What's the secret to installing PVC drains that don't leak?
My basement laundry tub started leaking at one of the trap connections. I replaced all the PVC piping, used proper rings and teflon tape, squared everything up carefully, tightened firmly by hand...and the dang thing still leaked. I tightened even tighter (by hand), but still it leaks. I took it all apart, re-installed...still leaks.
Is there a trade secret I am unaware of? Any tips?
Thanks,
Jon

Make sure beveled end heads out, I sometimes will apply pipe dope to the washers, this stops all leaks.

Yeah, brush the face of all the beveled washers, and the face of the p-trap arm with pipe dope... it is easier to use than teflon tape on those areas... then use a pair of channel locks to tighten the joints... not MUCH but you can definitely make them tighter than hand tight...

I've never used tape or dope on these hand fastened connections, and they've never leaked. Make sure you have enough 'pipe in pipe'. I usually cut the pipe so that it goes as far into the next fitting as it will go, then just tighten the rings.

Pendragon,
You're right, I had a brain cramp, I was thinking about NPT PVC fittings and all NPT fittings in general. I've never had to put dope or tape on the drain fittings.

I have needed to put pipe dope on the pvc type of tubular drains but not on abs tubular type of drains.
That pipe dope does stop the leaks.
Use it if you need it.
