    I have an elevated water tank (15 feet; 6.5 psi head pressure) connected to a diaphragm pump with pressure switch settings of 40-60 psi. Connected to a pre-charged pressure tank at 30 psi. I run overhead sprinklers which do fine with the pressure.

    Just added drip irrigation to water the pecan trees. It's on a separate valve from the overhead sprinklers. The 60 psi is blowing the emitters out of the poly pipe. Can I add a pressure regulator to the drip irrigation after it tee's off from the main line? I want to dial the pressure in the drip line down to 30 psi but don't know if that will have any adverse impact on the performance of the pressure tank or pump.

    Appreciate any advice

    Thanks for the reply. I know that downstream from the pressure regulator all will be fine and the barbs will quit blowing out. I am concerned that the pressure regulator will have an upstream effect back on the pressure tank and pump.

    Thanks for your response. I know the pressure regulator will solve the barb problem and that down stream from the regulator, everything will be fine. My concern is whether or not a 30 psi pressure regulator will have any upstream impact on the function of the pressure tank or pump.
