Return jet leak
Hi,
I have a leak in my concrete pool. I turned off pump and water level dropped 4" in 3 days until below return jets. Problem is I have 8 return jets so not sure which one(s) is leaking.
I live in Philippines so I'm sure pool construction is substandard. I have attached a pic of one of the return jets....was this installed properly? A "professional" pool company came in and sealed all the jets and performed a pressure test and said everything is fine yet pool continues to,leak.
Any idea how water could be leaking out through return jets?
Thanks

Re: Return jet leak
Hi,
Is your pool concrete (Gunite), vinyl, or fiberglass? Looks like vinyl to me.
Is it an inground pool or above ground?
Do you have a spa that’s higher than the pool?
In the picture it kinda looks like the vinyl is separated from the wall fitting.

Inground Concrete pool with tiles. No spa above the pool.

Re: Return jet leak
Accepting the pipes do not leak (from the pressure test) what height is the equipment pad in relation to the water line?

Re: Return jet leak
The pad the pool pump sits on is 4' below return jets. What keeps the water from exiting pool through return jets when pool is off, pressure?

Re: Return jet leak
The fact that there are no leaks around the pad means that the system is closed so wouldn't leak but would always be under positive pressure
I would suspect a fault with the spider gasket in your multiport valve allowing the pool water to run to waste
Is the waste connection plumbed in so that you can't see the leak

Re: Return jet leak
Actually the pump was leaking. I took pump apart thinking there was a gasket but there was only 4 screws which I wrapped with Teflon tape and tightened back up. So if pump was leaking then the pressure would be affected and water would drain out through the return jets? I have attached pics of pump that I took apart...thanks for your help..,hard to find anyone in philippines that knows what they are talking about.

It's very unlikely that the screws were the source of the leak as all they do are hold the parts together
If you don't have a gasket or "O" ring, clean up the mating surfaces and smear silicone lightly over them. Re assemble and leave overnight for the silcone to set before running it again

Which was obviously where I was heading, glad you found the leak. The bolts, as Dennis said wouldn't normally be a leak point unless they were loose, often they are blind holes to prevent leaks. From your first pump photo it looks like there is a large O ring (around 120mm dia) which should be silicon greased or some sealant as suggested.
It is still possible to get a leak in this situation as it could be via siphon effect, switching off the pump starts the siphon from the spider gasket leak.
Anyway good you sorted it.

Re: Return jet leak
I live in the Philippines where finding credible Pool contractors is hard. The contractor had installed a Chinese pump and filter. I have attached pics of the filter where water is leaking from multi-port valve and the sight glass is full of water and bubbles in filter mode. The backwash pipe is 20ft from house and is still wet even though I haven't backwashed in a week. My filter doesn't have a backwash valve like some of the pics I have seen online...was the backwash line installed properly? Could these filter issues be the source of my 2" per day leak? Thanks in advance

Re: Return jet leak
They are presumably above the water line? If so no to the source of your leak.
Sympathise with you problem, just replacing one of my returns, the fitting had broken after 17 years with some ground settlement. Liner is a bit stiff with age so having to go careful.

Equipment is below the water line

Re: Return jet leak
Right to the top of the filter?

Re: Return jet leak
Top of filter is probably a foot below skimmer drain pipe

Re: Return jet leak
Another question.....today I removed the multiport from the top of the filter. I turned off the power and closed the valves on the return line pipes, skimmer pipe and floor drain pipe. When I unhooked the pipe leading to filter from the pump it continued to drain water. Why would this happen if all power is off and valves on pipes are closed? If power is off should the water from the pump stop as well? Could that be how I'm losing water in the pool? Water is entering filter from pump when pool is off and flowing out backwash pipe?
