I have a moen t6125 that I am installing. Most of it is in place and fine but I cannot get the drain pipe to stop leaking. I have put the cap on above the sink(it,s a snap on type) and have tried several times to tighten the nut underneath. It turns but the seal doesn't stay place. I fell like I'm doing something simple incorrectly and need some help here. Thanks!
I have snapped the cap in place, and turned the nut underneath.
Welcome to Just Answer. I will do my best to fully answer your question(s).
Did you place some plumbers putty underneath the top (sink) portion of the drain assembly? This is the part underneath that which you snapped into place. Next I ALWAYS wrap the threads of the drain assembly with teflon tape to aid in sealing the nut which you are trying to tighten underneath the sink. The seal will squish into place quite tightly if you turn the nut enough. Then the drain will not leak.
Just one question: how long does plummer's putty take to dry? I put a generous amount on to keep everything in place.
Plumbers putty does not (is not supposed) to dry. It is oil based and keeps a flexible gap filling seal under the drain assembly rim that sits on the top portion of the sink drainhole outlet.
