Looking for Adhesive that can fix a leak on multiport valve cracks

[LightMoon]

Hello,

There are a tiny cracks (not many) on the base of the multiport valve and it leaks when is under pressure.
Any recommendation on the adhesive available in the market that you previously had a good result with?

Short of some major skills with epoxy (on the inside) I doubt that can be fixed. My suggestion would be to get a new one.

There's a slim chance you can epoxy it. * If* it holds, it will last exactly until you pull out of your driveway to work a double shift and when it ruptures, it will take the whole MPV with it giving you your very own Old Faithful.

However, Mr Murphy is funny like that and nobody will be home to appreciate it. You'll come home to need half the pool water replaced, a new pump, and cleanup any water damage from it flooding near the house.

I tried to look from inside but I couldn't get the defuser out. Not sure how it is fixed to the whole MPV.

Any recommendation on the epoxy adhesive? Each well-known brand has multiple types and quite confusing which one could bind well.

If you must forge ahead here, This link has 3 brands that members have had success with. Jb water weld is another frequent mention.

If you want to attempt a repair, I'd highly recommend Plast-aid. It yielded much better results than epoxy. I used it to repair my cracked SWG. It bonds extremely well with PVC, and it's unbelievably strong.

You can't put a band-aid on a pressure leak. Epoxy will not last long, if at all, as it is just an adhesive.
PlastAid, mentioned earlier, will actually etch into the plastic and form a chemical and mechanical bond, essentially becoming a part of the plastic.
Unfortunately, if there is a crack in that valve, it will continue to get worse and fail at the most inopportune time. Best to replace the valve and save the cost of the repair.

The neck of the tank is prone to cracking and you should verify if the leak is on the multiport or the tank or both.
