A few weeks ago I noticed water seeping from the drain which drains the pool overflow and the run off from the decking around the pool. Upon closer inspection, I noticed that the flow of the water from the drain increased when I turned on my pool pumps. I ruled out water coming from the overflow drain or from any cracks in the pool. After contacting my pool construction company they said they believed it to be a pump's overflow valve. They are sending out a "Leak Detector" guy later this week who is set to charge me $400 just to locate the leak.
As a result, I am here, on this forum. I am have no idea how a leak from the pump could end up in the drain. The pool company said they never use glue when constructing the drain pipes and they feel the overflow valve is leaking into a section that might have shifted and come apart.
Anyone have any ideas? I sure would like to save $400.
My pool is an in-ground pool, 110 linear feet and 40,000 gallons.
