how big of a drip zone are you installing? how many gpm do you have. if the zone is big enough you can run it.

jeff256, I am guessing here so please get an informed second opinion. Install a pressure regulating valve at the beginning of the drip zone and ahead of this device, make a bypass connection to the pump intake. Set the pressure regulating valve to the high and low settings and when the pressure from the pump is higher than the upper setting, the excess water would be shunted to the pump intake. But remember "one of the tragedies of life is the murder of a beautiful theory by a brutal set of facts".

Appreciate the thoughts. The lake pump puts out about 50 gph at 50 psi so why too much gph and psi. Need no more than 25 psi at maybe
