Hi, I have been noticing a loss of about 1/2" of water per day in my 1972 gunite pool in MA. I started noticing it last fall and shut it down for the year. The water level seems to stop dropping at the skimmer mouth. I checked around the skimmer mouth and other areas of lost tile with red dye and could see nothing evident. I did the bucket test last year and there was a difference between bucket and pool.
There is no leakage around pump.
Not sure what else to do. I can tell you the pool is really old and does need to be resurfaced. There are a number of lost tiles and all and the previous home owners did not open it for years and it was a black swamp.
Next year we are hoping to get it replastered and such. Any ideas in the meantime?
