I just installed a sprinkler service for my house and the water pressure was 40 psi which they said was too low for the system. So we installed a pump. They installed the pump so that it would increase pressure through the house plumbing as well. My question is that unsafe for the pipes in my house or the system in general? When you turn on the sink there is a delayed increase in pressure which is when the pump activates. Please advise. Thank you
