Question

Have older home in W.V. and as you know if you have been there, there ain't no flat spots. Have to use a Sears 1/4 hp pump to get
adequate pressure. Problem is that the bladder on the last 2 pumps have given out
in way too short of time. Am going to replace
with the same pump. Is there anything that
should be done before hand to prevent this ?
Maybe a trap ??? Any other type of pumps.
Also do these pumps run to supply pressure, that last ones seem to run off and on quite
a bit, possible leak ???

Cool

A 1/4 hp pump? Sure that it isn't a 3/4 hp? I would not use less than a 1/2 hp for water pump. Yes, water pumps have a kick-on minimum pressure to maintain water pressure. This is controlled by its pressure switch. A pump will cut on and off more if the bladder in the air tank is weakening. The bladder pressure is pre-set at factory to be near minimum cut-on pressure. You can check it with a tire pressure gauge, and air it up with a portable air tank. There should be nothing between the pump and air tank (no trap, etc.). Make sure that your air tank is large enough to match the pressure of the pump, or they can fail prematurely. Good Luck!

Your right, 3/4 h.p. shallow well pump. The
bladder is located in the air tank ? If so
replacing the pump will do no good. Do I need to replace the bladder ? is that possible ? Or do I have to buy a new air tank?

Confused...

The bladder is in the air tank, and if it has failed, you will have to replace the whole air tank. However, check the pressure in your existing air tank with a tire pressure gauge. It should be somewhere around the cut-on pressure of your pump (30 lbs?). If it isn't, try pumping the bladder back up with a portable air tank before replacing. Good Luck!
