Where's the leak?

[MiamiSun]

We have just taken ownership of an older home with an older inground pool. Over a period of about four days the pool is losing nearly four inches of water and the connecting spa which is set at the same level goes down about nine inches. The water level doesn't seem to drop while the pump is running, only when we shut it off. I've checked around the pump and filter system, even the skimmer, and I can find no dampness or condensation anywhere. Where should I look next?

Try to find the problem at the spa end. Could be a light fixture, return jet drain, ...

Any more details may help others here determine the problem better.

Come to think of it, the light in the spa is burned out. It is possible that could be the problem. I'll look into it. Thanks!

I just thought of something...

The pool loses about four inches of water and then stops, the spa loses about at least double that and then stops. Once it hits a certain point, the water level stays where it is. And when this happens, it is above the light in the spa, so could that still be the problem??

It could well be the light. The electrical conduit may be channeling the water out. It is almost impossible to know how the conduit was laid. If it goes up a few inches before dipping down again, it will only leak out to the level of the apex or peak of the bend/junction.

I suggest you remove the light and inspect it to determine whether the problem could be from the fitting.
