Plumbing advice

I am redoing the plumbing on my 120g tank.

There are two 1" overflows. My question is about attaching the plumbing (1" pvc) underneath the tank, to the threaded bulkhead underneath the tank.

I used a 1" threaded to slip adapter, glued the slip end onto my 1" pvc pipe underneath the tank, then screwed the threaded end of the adapter into the female threads on the undersurface of the bulkhead, using some teflon plumbing tape.

However there is a very slight leak (ie. a few drips every hour or even less) from the connection between the underneath of the bulkhead and the 1" threaded adapter. The bulkhead itself is not leaking.

My question is, should I just try and add more teflon tape then tighten the threaded connection tighter, or should I use pvc cement on the threaded connection?

i would use aquarium silicone.

i would use aquarium silicone.
if its a very very deadly slow drip, use silicone and seal up the joint. this will allow you to remove the joint in the future.

Not plumbing, but the furnace guy just left the house.

Amoungst other things, I asked was why they use joint compound not teflon tape, told quicker plus never leaks.

Wondering if some new tape and a little smear of plumbers putty might work.

Be a pain if you glued the joints then they still leaked.

Silicone all the way :cool: I have used this on high pressure applications with great results.

For our plumbing needs we use a couple wraps of teflon tape and silcone. Makes it a little easier to take a part later if needed. If you don't care for teflon tape then use silicone.

Ha a reply from me the plumbing geek - but I had a plumber come out and do the magic for my 190 recently and he used the teflon tape together with some liquid teflon. Comes in the same kind of little can that the primer and glue come in.

Do you mean aquarium silicone like the one used to make aquariums with, or silicone lubricant?
