I bought a Dolphin Pro 2011 for our pool almost a year ago and since about the second week it has been causing us problems. I noticed the water level dropping substantially every day, more than what could be contributed to evaporation.
So, I called out the pool company to take a look and they couldn't find any immediate problems. So, on came his dive suit and into the pool he went.
Ultimately, he said he was able to find about a dozen, very small tears in the liner. They ranged from the bottom of the pool all the way to the wall. He commented that he's repaired several dozen pools in the areas, all with very similar tears ... a lot of them use the dolphin. However he's never been able to confirm that it's the dolphin doing it, just that it seems to be the common link between all of the homes.
The liner itself we had gutted last season. It was all removed, the foundation and base were reinspected, etc and then had a new liner installed. Filled it up, let it sit for two weeks, divers got in, etc --- certified leak free, pre-dolphin.
So, the basic question still stands. Has anyone else heard or experienced anything like this?
I called Maytronics and they very quickly said that this was news to them. That they had never received a call about the dolphin causing tears in pool liners nor had any of their products produced such results in their tests. This may very well be true but of course, in my opinion, I need to take what they say with a grain of salt.
