Hi all,
Need your help in selecting the cut in/out value for a pressure switch. Here is my situation. We are on city water with 44 psi. Wish to pressurize hot water from a non-pressurized solar tank and feed the home hot water supply with a jet pump. Not sure if it matters but the solar hot water tank is on the roof 35 ft above the pump in the basement. This provides a gravitational 15 psi at the input of the jet pump.
Which pressure switch should be selected 20/40 or 30/50 psi. And should it have a low pressure protection (doesn't turn on unless there is a min or 10-12 psi) to prevent the pump from running if the tank is dry.
Thanks,
