Sealing a leaking return port flange on gunite pool

[etbrown44]

The pvc is stubbed through the concrete wall. The return port flanges are slipped over the pvc with a typical glue connection. It would seem that the failure is at this glue connection, as under air pressure when winterizing, with the outlet plugged, air leaks between the flange and the wall.

The return flange port, once installed, does have female threads, but that is just to accept an eyeball, or for plugging in the winter. Those threads, in this case, don't pertain to how it's installed.

So given this kind of setup, any idea as to how one would repair a leak between the pvc and the return flange - internally? Still use the hydrallic cement?

. . . pictures? . . .

the port slips over 1.5" pvc and glues on the back side.

Hi Ben,

I trust you view the pic, before it was deleted. (I did not see any mention of a copyright on google images, but no harm )

From what you saw, how do you suppose one cuts the flange fitting from the 1 1/2" pvc, still ends up with a clean pipe end, and still has enough to glue a new slip on flange onto it?

Have you possibly seen this done before.

Do you suppose in the alternative, it can be epoxied from the inside?

I have epoxies some hard to reach hot tub fittings.

tips appreciated!

Again, without seeing pictures from YOUR pool, I can't be sure, but MOST eyeballs screw-in, and most 'flanges' are either part of, or retained by the eyeball.

But . . . I'm not going to tell you to unscrew it, without seeing a good picture of the actual eyeball & 'flange' on YOUR pool.

Also, it's not too likely -- unless you've seen reason to think otherwise -- that the leak is from the pipe into the concrete. More common is a leak from the *pool*, along and around the pipe, through the wall, to the ground.

I re-read your first post, and realize it's not clear, so I'll ask. Is water leaking OUT of your pool, causing water levels to drop, OR is water leaking INTO your pool, bypassing the eyeball?
