Reply To: Water pressure system tank size?

[Robert Stephen MortonParticipant]

ddparker. install the biggest you can get or at least 5gal, then also install a pressure reduction valve to the outlet side of the pump to at least one lb below your bottom switch setting. That way you will get constant pressure, alternatively there are a multitude of constant flow pumps on the market that do not cycle.
See a pump man.
