pvc cement, needed on drain lines?

[Jandree22]

Soon going to start building my plumbing down into the basement, and I got a can of both primer and cement ready to go. I've heard that pvc cement is only really necessary on load bearing lines (ie, the return line) and not needed on the drain lines as the slip fittings do make a nice snug fit together.

I don't want disaster first and foremost, but slip connections seem to me to be very solid w/o any cement, and if possible I'd like to avoid as many cemented connections as possible for any plumbing maintenance down the road.

please let me know any thoughts, thanks.

ur going to want to glue it. ive got some drain pieces just slip fitted over my sump and they leak.

use unions if u want to be able to take apart the plumbing.

Yep, I didn't glue the last couple of pieces and they slowly leak -- not an issue for me, since it is over the sump.

And like "reef2" said, put unions in convenient spots so you can take it apart if needed.

put as many unions as you need to make cleanup as easy as you can.

not cementing will leak...meanning salt creep mold? possibly from moisture more cleanup loss of salt you get the picture.


unions go for about 3$ a pop and they will be your fav part of the plumbing

Pay attention to the inside diameter of your unions. Most are a little (1/4") smaller than the pipe they are designed to join. I always buy a larger size and then use reducers ($0.30 each) on each end so as not to reduce the I.D. of my plumbing anywhere.

ie; a 1" union is only 3/4 dia. on the inside.

use ball valves too so you can shut down sections for maintenance you will be glad you did later on

yep, I got some unions and ball valves ready to go

thanks again all.
