It is designed for perfect pressure inside the home. ![]() Also, the pump constantly shows an error message that there is no water when there is, which leads me to believe there might be air in the line between the cistern and the pump.Ī pump technician came out and said that the line from the house to the cistern may have an air bubble trapped and suggested adding a standpipe before the water enters the pump that I would fill to help prime, but that doesn't seem to have made a difference. SCALA2 is an integrated, self-priming, compact water booster pump.
