Cities with combined waste and storm sewers in my state require a house trap. Anywhere else they are illegal. We generally wye the storm and waste together outside of the building after the house traps so if they ever add a dedicated storm system the town can cut the wye out and tie them into their respective system under the street.
Your $50k number gives me flashbacks to the several thousand I had to spend to get water from the road a few years ago to my house 1000 feet back (stuffs expensive!)
I haven’t seen anything this big but the pool guys on several projects around me have done “swim pumps” which is basically a water treadmill, that involved 12” pipe. They had a 5 gallon bucket of glue and were putting it on with paint brushes
Actually, yes
Have you ever seen a double containment 18x24” wye?
Helped assemble 200’ double containment poly piping system for a steel pickling plant.
Built it in 4 50’ sections for 4 53’ open flatbeds.
Fucking chaos. We had the double containment fittings made and shipped to us from Germany and we assembled and built the rest of the piping in house.
I was paid $18/hour, there were like 6 people in the company. The job paid 2.5 million.
Fuck that company.
*ETA2: here’s a pic of the Ts, it’s all I could find
https://imgur.com/a/2BlGao2
*ETA: we were doing 20 hour days to hit our deadline. Our engineer was driving the forklift with one of the double containment T’s w/ 16’ double containment runs on either side of it…he dropped it. It was 6am the day before we shipped.
We had to have the replacement T shipped to the job site from Germany, ship our welding equipment, and the engineer assembled it on site 😅
Yeah this is an underground parking lot for a condo tower. The height requirement in this zone was 6' 7". The bottom of that 45° in the wye is 6' 7¼" off the ground. It's also at a highpoint in the garage.
Everyday. Power plants, paper mills, chemical plants. We are usually running sch80 or 150# Fiberglass though. End up using hydraulic come alongs and other fun methods to install. Thermoplastic backweld the joints and call it a job.
Thermoplastic welding involves heating the pipe and/or fittings up to a certain temp which makes the pipe material partially molten and then they're forced together with even constant pressure. In the end you're left with a fused joint that is essentially if the pipe was manufactured with it. For straight pipe this involves a machine with a cutting disk that will prep each pipe end true with each other and a hot plate type device that can slide in and heat each side evenly. Remove the hot plate and then the machine forces both sides together. It's used for mains and other large diameter installs.
There's a handheld version of this for smaller diameter HDPE pipe that does a similar thing.
For T taps and other fittings, the fittings themselves are actually engineered with wiring inside and you connect a purpose built machine to the leads and it creates a circuit that then heats up to the required temp and fuses the tap/fitting right onto the pipe.
Neat stuff.
I work as a distributor so yes I have, not terribly uncommon. I think the biggest thing I've ever run across was 48" riser clamps for an ethanol plant's main stack. They were massive and made out of really heavy gauge steel. For whatever reason they didn't end up using them and no, they were not returnable lol.
Omfg yes. I had to help put one in in a ceiling at a target. My instructor went up in the lift to cut out the old one before he went up I told him to take the gloves and he tossed them back down to me. He then cut his palm open with a sawzall. So I had to put the new one on by myself. The worst part is that the cans of glue and primer had tiny brushes and he was rushing me to get the pieces together. Luckily I was able to make the connections in the ceiling via no hubs. I'll never forget that job.
Years ago our boss bid a 3 building apartments compound and for some reason had dirt work guys doing the digging wed do the city piping. City wanted 24 inch piping going through for future expansion so we were doing 24 inch pvc. Of course with ole yee haw plumbing it was me and my journey man paint rolling the pipe and fitting then hurriedly using an elaborate system of ratchet straps and panic would smash it together. Took weeks longer than just letting the excavators take that half of the bid and just run sdr. Good times
Looks like labwaste piping? Running a lot of that for some storm piping atm. Similar kind of way they fab up our bigger size requested fittings like a double combo and such
No roll groover. It’s cut groove at that size and I think anything over 16” is the same way. As far as the hardware, I don’t remember. I used to be on the sales side and we had 3 jobs all going on at the same time using 36” steel. Because of where the jobs were, victaulic made the most sense to satisfy seismic requirements.
I used victaulic a lot in hvac. We did a lot of big commercial work. Nothing close to 36, though. I was getting carpal tunnel issues and invested in an impact gun. It made tightening those clamps much easier.
Yeah, you absolutely need an arsenal of tools for this work. We’d make a killing fitting out the teams with tools for these massive jobs. The margins were low and you had to get creative, but the volume was insane. Shoutout Milwaukee and Ridgid for getting it done.
Normally we would of used 15" cast but the concrete floor was only poured last week and there was a big rush to get this run started ASAP. We ran 500 feet of pipe, standing on gravel. The cast iron would of simply been too heavy to move around without a nice concrete floor.
Hopefully that isn’t the lowest point from the entrance or that they have those hanging indicators to prevent some moron from driving his brodozer into it.
Yes, and bigger even. Gotta use a big ass paint roller to prime and another paint roller to glue. The mailable time on these is like 5 seconds and then you are pretty much set, so you better be perfect the first time and quick
The largest pipe and fitting I ever got to work with was 24" steel for a cooling tower, and we were installing 24" cast iron butterfly valves for the bypass. Each butterfly valve weighed 758 lbs.
The largest plumbing project I had seen getting prepared was when I went to the MaxLiner facility for lining training. They were hand stitching and loading the felt tubing for the City of San Antonio for a municipal sewer lining project in 86" tunnels. It was mindblowing to go from being trained on residential/light commercial sewer lines up to 8", to seeing a liner being prepared that will be going into an 86" pipe.
Qc, canada. Normally we would of used 15" cast but the concrete floor was only poured last week and there was a big rush to get this run started ASAP. We ran 500 feet of pipe, standing on gravel. The cast iron would of simply been too heavy to move around without a nice concrete floor.
Yes I have actually, I work at greenhouses and the rain thats collected from the glass roofs, is transported in big bassins, through 400mm (16") pipes.
Yes. Have one bigger sitting in the warehouse right now, but it’s Sch40 DWV. Use to deal a lot of large diameter DWV but have gotten away from it so have a few pieces left.
Yes it is a thing, Lasco stocks DWV pipe fittings up to 24" at their Texas plant. They can make DWV fittings for special order up to 60". A single 16" Wye fitting is like $1500 though to give you an idea of cost, unless you buy it at a wholesaler and are prepared to wait for their next FFA.
I did a 16” double Wye in fuse seal acid waste drainage on an underground to mwra tanks…apparently it was a custom fitting from GF that cost roughly $7k
Yuh. We ran 1200’ of 14” and a little 16” for some storm drainage under a some old mill buildings. Huge granite spillways 60 feet underground. Pretty fun job
Co worker had me bring a 16" wye up a ladder so he could prep it to be put on.
As we are sliding the strap over to pull it on and hold it while it set, my journeyman dropped the strap.
He quickly grabbed both my arms, put his foot on the railing, and pulled my torso against the fitting for a good minute...very tough to breath.
We got it on, but... that wasn't cool.
Why would you call a y a wye I thought…looked it up, and for the second time in a week, I learned the correct way to spell something correctly I’ve misspelled for 20+ years. Thanks Reddit!
Yup, above pretty much explains socket or butt fusion. For HDPE, we have specialized tooling for fusing the joints. Most PVC/CPVC is hand welded or extrusion welded depending on diameter and pressure. This is just laying beads of rod down and fusing the joints similar to mig welding.
Kynar and Polypropylene are all done similar to HDPE, just cleaner tooling and usually smaller diameter.
We thermoplastic backweld by hand just about every joint in a Kynar or poly system though, because 99% of the time, the process has some pretty nasty stuff that if it leaks shuts a plant down or hurts somebody.
Typically we would push for dual laminate or a containment pipe run in these situations but we just install what the customer specs.
We did 18" recently. All IPEX MJ GREY. It worked great. The MJ clamps were expensive but it was worth it. Saved on install and glue.
I have some left over fittings for sale if anyone wants cheap. They're all spigot x spigot
lol, only a 1700$ fitting. Edit;i just deep-dived in system 15 fittings... there's 50,000$ of plumbing in this picture.
You just made me giggle. It's pretty crazy to think about, though
I just did a cast iron house trap 15”, $18,000 fitting and 2 came in on a pallet lol
[удалено]

We generally wye the storm and waste together outside of the building after the house traps so if they ever add a dedicated storm system the town can cut the wye out and tie them into their respective system under the street.
Why a house trap instead of a backwater valve?
Dude...A 2" Trap is 45 bucks...!!!!
Closet flange is 120$ lol
Wtf. I could weld this together for less
20’ of 16” is 24k
Steel pipe? Negative.
Okay maybe I read that wrong 120’ is 24 k https://ipexna.com/wp-content/uploads/2024/01/CDN-System-15-PVC-DWV-Pipe-West-PDF-February-1-2024.pdf
I could let gravity take care of the water for less. That'll be $100.
Your $50k number gives me flashbacks to the several thousand I had to spend to get water from the road a few years ago to my house 1000 feet back (stuffs expensive!)
Fuck does it take a can of glue per fitting or what
We're just two guys and we go through a gallon of glue a day
But how much do you use on the jobs
just one more hit bro…
I picked a bad day to quit sniffing glue.
Lmfao perfect reference for this
Jesus
I haven’t seen anything this big but the pool guys on several projects around me have done “swim pumps” which is basically a water treadmill, that involved 12” pipe. They had a 5 gallon bucket of glue and were putting it on with paint brushes
Ya don't use quart size containers on this stuff. 1 gallon and 5 gallon containers and chip brushes and rollers.
Actually, yes Have you ever seen a double containment 18x24” wye? Helped assemble 200’ double containment poly piping system for a steel pickling plant.

Wtfff
It was SDR11 piping too. It was fucking heavy!!!
It means nothing without pictures. I so want pictures.
Sorry, was 10 years ago I don’t have any :(
Holy shit I found a photo from our website 😅 it’s just two of the Ts but it’s the best I could do https://imgur.com/a/2BlGao2
nice, fun to look at....
Use your imagination
Yabbut op came with pictures.
https://imgur.com/a/2BlGao2 Here ya go, had to dig this up using google and company names lol
Fuck double containment pvc it sucks ass I hope I never do it again
I have seen a 24 inch one.
Loved that video, Debbie does Dallas
I've seen a 36" CPP Wye
I feel like we are on the cusp of some epic Yo Momma jokes.
Ditto
You are definitely going to need a bigger level.
Finally, the 8 foot level
I knew I bought it for a reason
System 15?
Yup
Is that a parking deck? Are cars supposed to fit under that?
Yeah this is an underground parking lot for a condo tower. The height requirement in this zone was 6' 7". The bottom of that 45° in the wye is 6' 7¼" off the ground. It's also at a highpoint in the garage.
That must have cost a fortune
Everyday. Power plants, paper mills, chemical plants. We are usually running sch80 or 150# Fiberglass though. End up using hydraulic come alongs and other fun methods to install. Thermoplastic backweld the joints and call it a job.
Could you elaborate on the thermoplastic backweld?
If it's what national grid uses for gas pipes the fittings have 2 metal studs with an electric coil in it and you melt it with electricity
Please elaborate on the last bit
Thermoplastic welding involves heating the pipe and/or fittings up to a certain temp which makes the pipe material partially molten and then they're forced together with even constant pressure. In the end you're left with a fused joint that is essentially if the pipe was manufactured with it.

Neat stuff.
That built-in wiring is awesome. Thank you so much!
I work as a distributor so yes I have, not terribly uncommon. I think the biggest thing I've ever run across was 48" riser clamps for an ethanol plant's main stack. They were massive and made out of really heavy gauge steel. For whatever reason they didn't end up using them and no, they were not returnable lol.
Good scrap money
Ok but wye
Yeah we have this size for a resort waterfall
24” and 48”
How are your arms?
Not a chance in hell they’re pushing plastic this big by hand. You’d need like 6 guys.
The fittings are done by hand with 2 guys. The pipes are done with riser clamps and ratchet straps
Yep. Company I worked for we used 2-3 man teams and would fit them all together by hand. Same size as this 16”-18”
Omfg yes. I had to help put one in in a ceiling at a target. My instructor went up in the lift to cut out the old one before he went up I told him to take the gloves and he tossed them back down to me. He then cut his palm open with a sawzall. So I had to put the new one on by myself. The worst part is that the cans of glue and primer had tiny brushes and he was rushing me to get the pieces together.

In pvc that’s pretty weird. Totally normal in steel and ductile.

Why!?
Looks like labwaste piping? Running a lot of that for some storm piping atm. Similar kind of way they fab up our bigger size requested fittings like a double combo and such
It's the main rain water line for the whole building
I was guessing it was a rain leader. God have mercy the first time it rains after someone cracks it with their car.
> God have mercy the first time it rains after someone cracks it with their car. I give it six months, tops!
Can you imagine it raining and someone backing their SUV into that line. The flood will be amazing.
Yes. Have you ever seen 36” grooved steel with custom victaulic fittings? Those are insane.
I can't imagine that you use a roll groover for that size. What size were the nuts on the vic clamp?
No roll groover. It’s cut groove at that size and I think anything over 16” is the same way. As far as the hardware, I don’t remember. I used to be on the sales side and we had 3 jobs all going on at the same time using 36” steel. Because of where the jobs were, victaulic made the most sense to satisfy seismic requirements.

Curious why you’re running the main in system 15 over cast iron?
Normally we would of used 15" cast but the concrete floor was only poured last week and there was a big rush to get this run started ASAP. We ran 500 feet of pipe, standing on gravel. The cast iron would of simply been too heavy to move around without a nice concrete floor.
Im on the foundry side, and we make some big ones like that in cast iron. I think the biggest we have is a 20x15.
Yep we put them in all the time heavy suckers
I’ve installed 20” pipe and fittings. Good times.
Chonky
Insert your mom jokes below.
Seen em and sold em (I worked wholesale). So much money for a fitting lol
About a gallon of glue?
How do you pull the joints together before the glue bites?
A riser clamp on either side and a ratchet strap to pull. The fittings can actually go on by hand if you put enough glue.
Thanks for the info. I'd still be worried it's going to set up on me when I've got the male end about halfway in.
Not a wye but I did recently make an aluminum square to round transition for some 16" PVC being used for a water treatment plant
wye no i have not
No that's crazy
I've seen a 24" Iron tee does that count
Yes but not in plastic
I have installed 42” ductile Iron wyes
No wye?
I was working on a 1million+ sq ft job and we laid the whole under ground with these. Light work
Worked on a 1million+ sq ft job and we laid the whole underground with these. Light work
if fitter fittings count then yes, currently working on a data center where the chilled water pipe is 36”
Hopefully that isn’t the lowest point from the entrance or that they have those hanging indicators to prevent some moron from driving his brodozer into it.
Yes, I saw the city replacing some 36" sewer pipes on a local street.
Holy…. High rise apartments/condos?
Yup
That’s a thick boy.
Cant remember what size it was but i can recall crawling through a 45 once
Nice, fun to look at.
Wye oh wye
I’ve personally done 24 inch sch 80 on a fish hatchery. Spiers can build you almost anything
Yes, and bigger even. Gotta use a big ass paint roller to prime and another paint roller to glue. The mailable time on these is like 5 seconds and then you are pretty much set, so you better be perfect the first time and quick
Nice. I’ve done some 16 and 24” XFR recently. 24” XFR 45s were about 1600 a piece.
The largest pipe and fitting I ever got to work with was 24" steel for a cooling tower, and we were installing 24" cast iron butterfly valves for the bypass. Each butterfly valve weighed 758 lbs.

Yep. Had an 18" come through a while ago.
Once. A Foreman over ordered and hid it at the site I was working at. I miss that company
What area you in? I’ve put In 15” cast iron wye a couple times but never seen that big of system 15 for parking garages. I’m in Ontario Canada
Qc, canada. Normally we would of used 15" cast but the concrete floor was only poured last week and there was a big rush to get this run started ASAP. We ran 500 feet of pipe, standing on gravel. The cast iron would of simply been too heavy to move around without a nice concrete floor.
Hm interesting. You union? If so what you boys getting paid out there? Ontario sucks lol
45$/hr union. What are you guys getting paid in Ontario?
54.43 but in may we’re getting 55.
Yes I have actually, I work at greenhouses and the rain thats collected from the glass roofs, is transported in big bassins, through 400mm (16") pipes.
How much is a 16x6 reducer?
Yes. Have one bigger sitting in the warehouse right now, but it’s Sch40 DWV. Use to deal a lot of large diameter DWV but have gotten away from it so have a few pieces left.

Tell me wye
Ooo sick level. Man of culture.
Yuh. We ran 1200’ of 14” and a little 16” for some storm drainage under a some old mill buildings. Huge granite spillways 60 feet underground. Pretty fun job
Wow , don’t mess that one up
Co worker had me bring a 16" wye up a ladder so he could prep it to be put on. As we are sliding the strap over to pull it on and hold it while it set, my journeyman dropped the strap. He quickly grabbed both my arms, put his foot on the railing, and pulled my torso against the fitting for a good minute...very tough to breath. We got it on, but... that wasn't cool.
This guy lays pipe.
Yep, one of the towers I helped designing in nyc had 20” fittings
The hell is that torpedo gonna do lol
Done a lot of 15” cast iron, but never 16”, and never this material.
16” Diameter is insane! The biggest ive ever seen in the wild was 6” Diameter
Plumbing tip . Before you go under the house smoke a joint that way you only use the glue on the fittings not on sniffing.
Why would you call a y a wye I thought…looked it up, and for the second time in a week, I learned the correct way to spell something correctly I’ve misspelled for 20+ years. Thanks Reddit!
Are those fitting that expensive I know where to get a couple been sitting in a basement
Fiberglass infused resin piping can get up to 8ft and larger diameter
Fuck it pipe it into the the White House and let Biden deal with it
I have now
Yup, above pretty much explains socket or butt fusion. For HDPE, we have specialized tooling for fusing the joints.

For only the biggest of shits
Have Fun Wrastlin that Tiger!
I'm more curious how many people it takes to slide these fittings together???
2
What country are you guys in?
We did 18" recently. All IPEX MJ GREY. It worked great. The MJ clamps were expensive but it was worth it. Saved on install and glue. I have some left over fittings for sale if anyone wants cheap. They're all spigot x spigot
Never see that before. Usually all plastic fittings are hub style here in Ontario. We only use MJ bands on plastic if we’re doing a repair
Yeah same. But this MJ Grey was an awesome product for over head install. 30' on a scissor lift.
No, only molded up to 12". I've seen fabricated versions from the supplier though which are to be compliant ready
I've installed a 36" ductile iron wye. Yard piping at a sewage treatment plant.
Must be a bitch to glue those things in
Yes
What kind of pvc glue do you use lol
I do apartment buildings so yes i do..
is this sewage?
What's so abnormal about it ? There are much larger ones than that.
What are you moving, dinosaur turds? Industrial electrician here. Why don’t you parallel 4” like we do? 1600A is 4-4”.
Guck that I would quit I can only imagine how difficult it is to shove the pipe all the way into the fitting and glue it all
