as the title says I am losing 1/2" everyday.
here is the info, IG plaster pool with an attached IG spa, that is 2 feet higher than the pool. Spa has a waterfall overflow into the pool. the waterfall is about 3 feet wide and I have pretty decent flow over the waterfall with some splashing off the brick pool edging.
If I bypass the spa when I run the filter, so feed from the skimmer or pool drain, and return to the pool jet or pool drain (yes I can return to the pool drain) I only lose about a 1" of water a week. If I include the spa, feed from the skimmer or pool drain, and return to the spa. I lose about a 1/2" a day. now I have a crack in the spa plaster(I learned the hard way that you shouldn't leave a paster spa empty in 100 deg weather) that leaks some water, and a tiny leak coming from one of the spa jets. If the I don't run the spa, I lose about a 1/2" of water a day out of the spa. Spa dimensions are about 2 1/2' x 4 feet, so I think that is about 36 gallons a day. If return to the spa, I lose about a 1/2" a day out of the pool in stead of about 1/7". at a 18'x48' pool I calculate is about 2500 gallons instead of about 700 gallons. So could I really be losing 1764 gallons a day out of the waterfall? I can see almost all the spa plumbing ( i have dug it all up to fix previous leaks) and there are no leaks, so if not the waterfall, where could the water be going?
I am not even sure if 1" a week is an acceptable loss for our pool, but that is about the lowest I have been able to get it since we bought the house and it was losing 4" a day. is there a way to calc. what the evaporation should be so I can know for sure that I am losing water somewhere else?
Thanks and any help will be greatly appreciated
