Hi, the place we used to live had a lot of sand in the well to the house. It would plug up the hot water tank. There would be sand in the bath tub. Sand in the sinks etc. Finally after burning up the hot water tank and couple times. The land lord put a sand trap in at the well house. Sure did help matters. But we had to change the filters about every 2 to 3 months.(posted 9013 days ago)
