Good evening. My 4.4 gallon pressure tank arrived today. I adjusted the pressure to 28 pounds to match my 30/50 pressure switch. I followed instructions to adjust the csv. The bolt on the top is almost all the way down to get to 40 psi while a shower was running. Shower head is newer,, within 8 years old. Is it normal for that screw to be adjusted all the way in to get to 40 psi?
Thank you
