Pleases help me find a leak in my pool. I am losing about an inch and a half a day and my bucket is not losing anything. There are no bubbles from the returns when the pump is on (it runs for 12 hours on a timer). It is a concrete pool and I do not see anywhere where it would be leaking. In the spring I did use some dynomite pool patch in a few areas on the side of the pool but when I chipped away any loose gunnite it did not show any holes and the patch went on very well covered and worked very well (I recommend it but it dries extremely fast). and I used some mortar to reattach some tiles. All of this work was done well and all areas were well covered. I dont think this is where my leak is. My guess is possibly the main drain. I will check the pump in the am to see if any bubbles but I recollect that there are not. Do you guys have any guess as to where the water is going?
If I wanted to test the tiles which I installed or the main drain what is the best way? Is there a simple way to perform a die test? maybe food coloring? or thread?
I would like to get this sorted as I have already put in a lot of time for the pool as well as the repair above, I replaced the pump with a rebuild and redid some of the plumbing.
Thank you for any help. I will post a pic of the pool soon.
