Inground leaking, tried almost everything

Water level falls to just below the water return. There are no cracks of any kind. Dug up pump hoses, found leak and repaired. Still leaks. Filter now spews sand into pool. Questions: Can changing the filter possibly eliminate the leak? Can the leak be in the main drain? If so what can be done? Any advice is greatly appreciated.

Given that the water drops just below the return fitting(s), inspect around the outside edges of the return(s), especially just under the return fitting(s). I often find leaks in this area. If the water hasn't fallen below the light, you'll need to inspect the niche and conduit for leaks. I'd discount a problem in the main drain if the water loss stops just below the return(s). Don't attempt to dye test with the water level down, refill the pool first.
The filter problem is another issue. I would suspect a broken lateral in the bottom of the filter allowing sand back to the pool. Replacing the filter won't help the leak problem unless the backwash valve is leaking to waste, in which case a new filter and valve would solve the leak and the sand problem.

Thank you for your reply. I don't have a light and there are no cracks around the returns. I may replace the filter and hope that solves it. Thanks again.

Instead of throwing your money at a new filter which only needs a new lateral. spend your money on a company that does pool leak detection. to find someone in your area check out leaktools.com . Sounds like a main drain problem to me. plug off your plumbing and see if leak stops. if it does its in the plumbing if it continues its in the pool shell.

The bottom of most skimmers conforms to the depth of pool returns. It is not uncommon to find a leak in the bottom of the skimmer itself or in the pipe that attaches to it (especially if it is threaded). Most skimmers have 2 holes on the bottom. If the failure is on the pipe feeding the pump (usually the back hole), the pump will work well for a while until it drains the cavity around the leak. Then air will begin to enter the system and the pump will begin to loose prime. If the leak is on the inside hole or the skimmer structure itself the pump will function fine but the pool will continue to drain to the level of the leak. Many of the first generation plastic skimmers have had to be replaced because of cracked female threads on the skimmer base. Some have had success with epoxy and an insert to bypass the crack.

I have a pool leak around the outside concrete area of my pool, which is wet. What do I use?

Hi, I can only tell you what I've used on my skimmer and cement leaks that has worked great. Been told this will not work on pvc. "A+B Epoxy putty." Costs about $20.00, cures underwater. Bought it at my local pool store. Good Luck
