I called American leak detection when my pool serviceman couldn't figure out why my water levels were fluctuating and water bill was high. They sent out Rob and he is very sharp and fixed it with a float replacement part. It's always good to get a second opinion. He was one of the nicest techs I've ever dealt with and his charge was much lower than the original estimate. If I could give 10 stars I would. My pool serviceman is also Rob of Buckeye Pool Service and recommended American Leak Detection. So glad he did. It' a franchise based in Palm Springs. Fortunately there were no leaks.
