My wife and I purchased our home August 31, and as part of the closing the previous owner was required to fix a leak (I noticed a large water loss from one day to the next during a walk through). He paid Hamlin Pools to do a leak test, and they said both skimmers were leaking. Both skimmers were replaced, plumbing was redone from those skimmers, and deck was replaced and buffed. Looked good as new. At this time they noticed the main drain was plugged and tried to blow it without and success. I have been pretty much running through the skimmers since then.
I was following BBB and doing great, until I noticed I was loosing CYA. I would put some in, and wait to test. The numbers would be great, and a test a week after that should no CYA. I did notice I was loosing chlorine way too fast so I tested the CYA again.
I notice a bit of water coming out of the pump's pressure side connection, and used our home warranty (actually worth it) to get a brand new pump connected. Still losing water though.
So, early October I called Hamlin Pools to come and check to see why the pool was still leaking. I got a bit of a run around, and they finally just came out this Monday.
Hamlin Pools says that after they did the prior repair (skimmers) they did a pressure test on the skimmer lines which were fine. They did a bucket test yesterday which showed around 2" of water loss in a day, and a hydrostatic test on the skimmers which showed not leak (no water lost).
The water level is now about 1/2" under the highest skimmer and right at the lowest skimmer, and Hamlin has marked the bucket again to see if it continues to leak.
At this point the water is no where near light or returns.
I've attached photos for review, sorry for the unclean pool I have not wanted to put in any money till this is figured out. Any cracks on the deck have been there are while, the house has had previous settling and engineers said it has stopped. Any ideas or opinions are appreciated.
Pool is around 11K gallons kidney shaped, 1.5hp hayward pump, 36sqft de filter, 3-5 feet deep.
