In response to Re: Water Pressure Problems
: : : I have a problem which I hope someone can help me figure out.
: : :
: : : Lately, the water pressure in my home seems to go real high and extremely too low. I have checked all the pipes and cannot find a leak.
: : :
: : : I had the submersible pump and the piping to the well replaced about 3 years ago.
: : :
: : : When taking a shower and turning on the faucet, I lose water pressure all-together. I am wondering if it could be a water-logged pressure tank or a bad switch.
: : :
: : : If it is a water-logged pressure tank, how do I check?
: : :
: : : The pressure gauge seems to go too high on the pressure tank. It goes to 86-87 lbs.
: : :
: : : Thank you. I appreciate any advice you can offer.
: : Dave; First remove the valve cap on the top of tank and let a spurt of air out. Does any water come out? If not, then Drain the tank (pump off) and check what the air pressure is in the bladder....It should be 2 lbs less than your cut-in pressure. Is this 86-87 lbs when the pump shuts off? Normally, a system has a 30 on/ 50 off, so the air would be at 28 lbs. Post back with info and we will advise further. Hube


Hope you got your water system fixed. I was having the similar problem and was searching for an answer. Tried the recommended fix about cleaning out the pressure switch, but when I took it off there was nothing to clean out. Finally did some experimenting and found out that the pressure gauge was reading 4 lbs high, and with the pressure switch set at 40-60 it was actually 36-56. This meant that the pressure in the pressure tank (38 lbs) was 2 lbs higher than the cut-in pressure, thus, effectively draining the pressure tank and loosing most pressure before the pump cut in. I finally measured the pressure from the valve on top of the pressure tank when the pressure switch cut in and found out it was cutting in below 38lbs. When I adjusted the pressure switch to cut in at 40 lbs as indicated on the reading on top of the pressure tank things began to work well again. I just need to remember to replace the pressure gauge before I forget that its reads 4 lbs high.
