The staff at this store are so helpful and knowledgable. When you describe a situation they can offer solutions and they are trustworthy. Our pool pump gauge was over 40 psi and it normally is supposed to be about 12-15 psi. It is very old and they suggested just start out by replacing the gauge if everything else seems to be in order. We got a new one and it works as designed.
They also demonstrated and explained how our sand filter works and how to change out the filter material and choose dolomite or sand.
