We are on a community well and the last time the pump burned out, the Einstein who controls it replaced a 10 hp with a 5 hp. AND we have added two new houses tot he system. The pressure in the house is acceptable, but now my auto sprinkler system doesn't have enough pressure to rotate the heads. I have replaced all the heads with low pressure heads but it doesn't help. Is there such a thing as an "accelerator" pump I could install under my house where I take water to give me better pressure?
