Does the motor turn it self off after a couple of minutes of no pumping?= ran out of water. If there is water up to the pump and still no water, check filter/s ( if there is any). Undo V band and check pump internals, impeller may be broken from shaft? When putting back together tap V band with block off wood or back of screw driver evenly as you do up the clamp to stop it distorting

Hi,After my wife had a shower the pressure in the pipes seem to drop heavy.Not just in the shower but the whole house's.Cold water comes out like a dream but dont know if it can be the pressure valve.


That sounds like a supply problem if it affects all taps (faucets). With no water running in the house, take a screw driver and put the blade on an uncovered supply pipe, put the other end to your ear and listen for a shushing noise. If you can hear it, you have a leak in the supply outside. Call the water supply utility. If there is NO noise, contact them and ask if they are throttling supply for the summer.

There is a high pitched sound coming from under my 2002 Jimmy. It seems to be originating in the vicinity of the fuel tank, catalytic converter, differential area. But I cannot isolate it. Possibles?


Fuel pump in the tank makes a high pitch sound which is normal. Turn your key in the ignition, but don't start, you should hear the high pitch sound with the pump priming the system. You will still hear it when started, it's annoying but normal. Different brands are quieter than other, I just replaced mine with a Delphi brand fuel pump which is a tad quieter than AC Delco stock pump.

Last week my electric power went off for about one hour, in my kitchen I heard water rushing out my drains. when the lights came on I had no water.The well man came and said he had to turn my pressure...


It sounds like the bladder in your pressure tank is water logged. Turn your pump off and open a tap and let the pressure off. Once the water has completely stopped coming out of the tap go to your pressure tank and pump air into it. There should be more water come out of the tap. Continue to pump are in until you reach the pressure recommended for your tank and there is no longer water coming out of the tap. Close the water tap and turn the pump back on and this should fix the problem. If it does not you will probably need a new pressure tank. The bigger the pressure tank you have also will make the pump work less. I prefer a smaller one myself as there is less change in the shower pressure when the pump cycles than with a bigger tank but this is just a matter of prefference. Some people prefer a larger tank as it uses less power by the pump not working as often.
