I was having some trouble with my pool and after doing some research and talking to the people at Imperial Pools I discovered that it was my heat sensor. I went ahead and purchased the new heat sensor from these guys and of course as soon as it came my pool started working properly again. Fast forward a couple months and my pool started exhibiting the same symptoms and luckily I already had the heat sensor on hand. The heat sensor is working wonderfully and my pool has ceased acting up which I am loving. These guys give good advice and sell good parts, definitely recommend them.
