Pink Dolphin is one of the more trust worthy service providers here in Phoenix hands down. I had them replace my old sand filter on my pool a few years ago with a new cartridge filter and I just recently had them replace my pool pump motor with a new dual speed motor. Both jobs were hassle free and done right. I have Pink Dolphin come out and clean my pool filter cartridges every six months and the technicians are always on time. Steve the owner always returns my phone calls and emails and handles every job we've ever had with a level of professionalism rarely found with other contractors and repair "professionals" here in the valley. Great company.
