In response to Re: pressure tank
: : My pressure tank is set to turn on the pump at 40 psi then shut off at 60 psi. here in the last week or so, the pump has been running every time a toilet is flushed, shower goes on etc. I noticed that when the pump comes on the psi goes to 45 then shoots up to 60 and the pump shuts off and then the psi drops back to just above 40. usually it would pump up to 60 then gradually decrease as the water was used until it hit40 and the pump came back on. I can manually force the contacter to make the pump come on to build the pressure back up but it shoots up very quickly. psi on tank is 35 with a tire gauge. wondering if there could be a hole in the bladder. what do you think?
: : thanks for your thoughts
: Bill; To see if the bladder leaks remove the air valve cap and release some air. If no water sprays out, then the bladder is not leaking.....To pressurize the tank properly, DRAIN ALL the water from the tank,then pump in air so its 2 lbs BELOW your cut-in pressure. Now go thru a few cycles and see if this helps. Let us know how you make out. Hube

ok, I pulled the cap and released some pressure from the tank and no water. drained the tank thru the boilercock at the bottom and figured if I put air on the top valve, if there was a hole in the membrane/bladder, then I would be able to feel the air coming out the discharge boilercock
Nope,AFter the water was out of the tank, the bladder held about 10-12 pounds of air so I am assuming that the bladder is not torn and is holding air. Pump still surges after it kicks on there is about 36 lbs on the bladder gauge and the pump comes on at about 38 pounds. it still comes on then slowly builds to about 42 then about 45 it shoots to 60 and the pump kicks off then the pressure levels off at about 42. this one has me stumped!!!
