I have an 18x36' lazy L inground pool in my backyard. It has a skimmer hole and 3 return jets
I am using a supermax pump and a sand filter at the moment
I did the bucket test, and the water remained the same after 24 hours
however, when I turned the pump on high for a couple of hours, to get more chlorine into the pool, the water level dropped dramatically.
The skimmer line is under ground for 15 feet then goes into my garage for 10 feet. The return line is in the garage for 10 feet before it goes under ground to the 3 returns.
There doesn't seem to be any water leaking around the pump/filter, so where did the water go, and how can I check for a leak somewhere? Is this something I can fix myself or am I doomed to call in a professional? I have tried reading up on it, but there is no place to find a consistent answer unfortunately.
