questions re: pvc piping fitting, etc

[mas985]

I am not sure about the grey to white but I don't think it is a good idea. Anyway, what I normally do with usual success:

1) Fit all pipes before prime. Priming softens the PVC so you do not want to disturb the pipe after priming.
2) Prime both parts. I found that waiting to glue is not necessary.
3) Glue both parts. I apply glue on the male side first and then the female side but I do not redip the applicator so as not to get a lot of glue on the female piece.
4) Insert pipe but do not turn more than 1/4 turn.
5) Do not stress too much before 15 min. and pressure test after 2 hours.


Good luck

thanks a bunch for the quick reply gents..the common thing seems to be that i didn't put glue on both sides so it sounds like i got lucky on some joints, likely just happened to smear enough for it to work on some..i'll know better next time..as always a great forum and in the short time i've been here..it's become a favorite!

Yes, it's not "glue" it's "solvent" - and you are not gluing PVC together, you are actually *welding* them together. Yes, there's a difference :-) glue is adhesive (e.g. sticks stuff together without penetrating the stuff). PVC cement is actually "melting" the pvc during the join/weld. So it's important to use glue on both pieces, so that the solvent has several seconds to start melting the PVC so that when you push them together both sides are squishy and slightly melted.

well, now that makes a bunch of sense..who knew..oh..you guys did

Here is a link to a great video that I train all of my staff with. It goes something like this:
Cut the pipes, debur inside and outside edges, check the fit (male fitting pushing 2/3 of the way into the female is perfect), primer onto female side, primer onto male side, glue onto male side, glue female side and glue male side, push fittings together and 1/4 turn. I just finished a commercial plumb job with 700 connections and didn't have a single leak using this method. You shouldn't have a problem using the grey electrical pipe and the white pool pipe.

awesome stuff...having had leaks after doing 2 different parts,i was starting to think i was hopeless and would have to get the pool dudes out..now,if only i wasn't scared of breaker boxes..then again, that's a mistake that could be deadly
