The fittings push apart because the hub of the fittings are tappered meaning the further in the pipe goes into the fittings the tighter the fittings get and that’s why you have to hold it until the glue and primer set up

Once I watched him go and nail the 2x6 on top of the wall top plate I said I must watch the rest this kid knows right what he is doing!

2 days just for pvc we do 3 houses in one day

10:11 b/c the chemical reaction in the solvent cement that is “chemically the 2 piles together is an exothermic reaction…..meaning it’s giving off some heat (very low amount) and it’s causing it to push back against each other, fighting….if you will while the 2 piles become one, which happens in matter of seconds; but will fully “cure” in few hrs. After few seconds, it’s “settled down” and the reaction still takes place but the push back is done.

My brother in law remodeled his whole home and when the GCs did the bathroom they had to redo shower drain as forgot to connect to DWV to house (slab on grade and was already filled with cement and tiled, DOH), then, after redid that and hooked everything up, they realized THEY DIDNT TIE INTO ORIGINAL VENTING🤦🏼🤦🏼, so, they had to add AAVs (which personally, not a fan) and called it good. Week later, bathroom sink underneath flooded bathroom, DOH, as they didn’t cement any fittings in, AND, overflow now hooked up AND the tailpiece wasn’t lining up and forced into p-trap (we talking 4 inches OFF!) and was putting pressure on other piles and without glue, it broke out, 🤦🏼
Can ya guess who the plumber was…..😉

Good guess on pipe separation. At least that’s what I was always told is that it was thermal expansion that pushed fittings off. I thought it was interesting he used a long sweep for the lav drain. I’m not saying it’s wrong because it is technically code. I’ve always put short 90s on sink and lav trap arms. The main reason I do this is so that I only have pipe going through the drywall. The escutcheon fits better and everything looks nicer. If you use a sweep you have the hub and sometimes part of the bend coming out of the wall. As for how it drains, the reason you can’t use regular 90s or tees is because it’s a change of direction and a short fitting stops the waste before it turns so it slows it down. If you use a long sweep (effectively two 45s) or combo, you’re not stopping the flow as it changes direction. When the short 90 is on the trap arm, the waste is just coming out of the trap and traveling a few inches. So it doesn’t have any momentum to slow down anyway. I’ve never had an inspector say anything about this.

Im a journeyman in Kentucky no wet vents are allowed on any fixture nice looking job also we don't use purple primer

[Aepek]

Nice vid, and a tip for anyone dealing w/ purple primer (pro or DIYer).
1:01 & 9:23 ¹ see that purple pain in the butt primer in this shot; taped to the solvent cement, like everyone does….
This fine for a rough in job, but for all that’s holy; if on a finished job inside someone’s house (regardless if they have $20 dollar fixtures/appliances/etc….. to a million dollar bathtub, PLEASE PLEASE PLEASE PLEASE, cover your work surfaces with a good heavy duty no leak canvas drop cloth when using purple primer (or just use clear cleaner if code allows in jurisdiction), b/c the worst thing that can do is get that primer inside a tub (which Halle Ed to my parents new jet tub 🤦🏼, and my sister’s new free standing soaker tub 🤦🏼 . And the soaker was $8500 🤦🏼) or countertop, floor, etc… BECAUSE THAT STUFF DONT COME OFF😉
cheers✌🏻

I am 1 in a crew of three. We get 5 bath houses done in 2 days. The 5th bath is typically an ejector pit with a 3 piece groundworks.

It would be helpful if the camera was actually pointed at the plumbing work.

[BaconJD]

It’s called interference fit why it pushes apart

[florence]

[lachcik]

minnesota requires your lettering on the pipe to be shown? wtf? lol

[jwfybgu]

why are you using pvc pipe . is it because it's cheap or you guys are cheap?

[Thetimberteam]

Please check out our page as well, we'd love to work with you some day!

[AtrGreasemonkey]

hole saw right through the support cutting half of it off..Stopped watching as soon as I seen this..

[cassidymichael]

Is there some new PVC where you don't have to hold it for like 10 seconds? I always have the problem with a Hydraulics out on me after I put it in the fitting. And I don't know what you're doing running the job and drilling I never saw those two go hand in hand before
