I've done some research but can't pin down what wrong with my pressure tank. Ever since I lived in my house my pressure tank has always kicked on/off very often, running a shower or a toilet filling up causes it to kick on more than once every minute. I decided to test it and determined my drawdown is only 1.25 gallons, my pressure tank is 20 gallons and says it's factory charged to 30psi. I've read drawdown for a 20 gallon tank at 30-50psi is about 5.5 gallons. What's wrong with mine?
One odd thing I noticed is the pressure at my whole house filter goes down to about 30psi and almost 60psi on the high side, when the water is running it will drop from 60psi to 50psi within a second or two. Is the pressure switch/valve suppose to spike the pressure above 50psi if it's set to 50psi? One thing I did notice is my pressure tank tee has no check valve, is that required? Is it possible my tanks air pressure is screwed up? Is it possible someone set the pressure switch to 30-60psi, can it be set to any low and high pressure within spec?
Questions?
-- What do I need to look at to try to get back proper drawdown for my 20 gallon tank?
-- Since the water pressure appears to be cycling between 30-60psi, do I just need to adjust it to be 30-50psi or 40-60psi?
