Hi Guys,
Just received my booster pump for the merlin(70lpm,big brute of a thing)
Problem is I've calibrated it to the best of my ability but I can't seem to get it to run constantly.
Original psi. is 31,booster pump switches on and it hits 65psi,cuts out and drops to 50 psi before it turns on again,then repeats and so on.
Any body got this type of pump and can help with the calibrating??
