pool leak?

[phillipjko]

I have an inground pool 18 x 32 with steps. I done the Pool bucket test. It stays the same when the pool is off. When I turn it on I lose about 1/2 inch per day. I have patched all visible small tiny holes I can see below the 9 foot deep water.... ranging from 4 ft deep to 9'. Skimmer seems fine... liner is about 7 or 8 yrs old now. We had asked American leak to come before we actually changed the liner. Now the price is about $600+. I do not want to call them in fix it and then about 6months to 1 year I change the liner. It would be a complete waste of money then. Should I just change the liner or ask American leak?? The pump leaks a little... the ball valve on the pump itself when doing the backwash is secured by a valve. The pool filter itself does not seem to be leaking anywhere. It was not leaking for the past 6 years or after I had replaced the liner. I use Fix a Leak on the skimmer. Pictures here show the steps, 2 skimmers (both on opposite sides), the filter itself (filter, chlorine feeder, SWG, etc). I checked backwash it seems not to be leaking on filter and outside. There is also some rust like stain a little on liner.... There was some crack on the skimmer sides before which I had used epoxy to fix about 6 years ago (not relating to liner--- see the skimmer open one with the star sponge). It seems to be ok.. maybe there is still leaking? Anyone knows how to fix stain? When I use Jacks magic purple stuff it comes out after 3-4 days of the pump... iron in water. Pool is balanced chemically using taylor kit.

According to what your symptoms are, you have to have a leak on the PRESSURE side of the system, not in the suction side. Even with the system off, there is water in the skimmer and if there is a leak there it would leak with system on or off. BTW, what does it matter if there are some leaks when you backwash?

What is meant by Pressure side of the system? When the pool is not running the water level stays at '0' loss for 3-4 days.. when pool is on pool level drops 2-2.5 inch every other day. How to correct this problem. Pool was not leaking since summer only after about a month the water level drops every now and then. I was not aware only till lately...

It seems you have started another thread with the same question, unsure why. The pressure side of any pool system runs from pump to return jet, water features, etc. The suction side runs from skimmers, drains and vacuum ports to the pump. With the pump running, the suction side will only suck in air, not leak water. So. if you are losing water when the pump is on, it has to be somewhere from the pump to the returns.

Other than that, you will have to do some troubleshooting or have someone else do it to find the leak, no one here can find the leak for you. Once you find it, let us know if you need any help fixing it.
