Re: sealing the intake and return

You can use silicone but I don't recommend it. The best thing to do is put the gaskets in the proper order and tighten them down correctly. It usually doesn't require a lot of force to get them to seal. When putting the skimmer in don't tighten the screws down until you have them all in and snugged up. Then tighten them from the center out alternating top and bottom, side to side.

should i lube the return along with plumbers tape?

just installed new liner. water is filled pretty high. its at the point to where i can install the intake and the return. my question is: when i screw together the return do i just use plumbers tape or should i use plumbers tape and lube. or should i just use lube.

the reason im asking is because we kept having a steady drop of water coming from the return. THANKS TFP!!!!!




i tell everyone at the poll stores about this site!!!!!!

You should really use paste for plastic piping. It works better than tape especially for larger fittings.

also if i use this paste and have to replace another liner in the future how hard will it be to break the seal?

The paste is for threaded fittings. If you have hoses and barbed fittings you can use silicone caulking on them and it helps. You have to let it dry before exposing it to water. It's hard to get off once it's cured but it can be done.

Re: im confused!!

O.k. so the larger piece fits inside the pool and the smaller piece screws into it from the outside, correct? Do you use a nut outside the pool to secure the larger piece to the pool wall?

Re: im confused!!

Use a non-hardening teflon based pipe dope. Pipe dope works better on larger threaded joints, while teflon tape is better for smaller joints.

Re: HELP

If sand only went into the pool just once that is alright. But if it does that again, something is wrong. Really, sand shouldn't ever get into the pool, but now and then when you are first setting things up some sand gets into the wrong place and ends up in the pool.

The black gasket should seal tightly to the pool. The key thing is the gasket on the water side of the wall and how well it seals to the liner. The black gasket on the outside is much less important. The gasket should be free of any nicks or cuts and clean. Any dirt or debris can prevent it from sealing properly. You can also have problems if any of the plastic parts crack, which can happen if you tighten it down too much.

HELP

Seeing that it is coming from the wall surface I would agree that it looks like the seal is bad or that it could be tightened down to much and making it pinch. If it were me that is what I would be checking out first.

Re: HELP

also with that non hardening paste should i just add more and tighten the pieces down more?

Re: HELP

The paste isn't important for the return fitting sealing to the liner. If you are having leaks from the threaded fittings on the filter, tighten them down some more.

There should not be anything between the outside pool wall and the black gasket. It looks like you may have some pipe dope under there, so clean it off if you do. The pipe dope is to lubricate and fill in the threads when pipes are screwed together. It helps seal threaded connections by allowing them to be screwed together more completely and filling in any tiny gaps where the two pipes are screwed together to prevent leaks. It will not make a watertight bond between to flat pieces of material.

Either clean or replace the black gasket and re-install it on the outside of the pool. You can use a little pipe dope on the nut that holds the return fitting to the pool wall but not on the gasket. Snug the nut a 1/4 turn past hand tight. If the connection still leaks, plug the return and dry the outside area well. Apply a bead of clear silicone caulk around the outside edge of the return and allow to cure as per package directions. Then unplug the return and test for leaks.
