Our water pump in the basement lost all pressure yesterday. We have taken the pump apart 3 times and put in new parts. We still cannot get any pressure to stay. How do we fix this problem or find out where the air is coming from? HELP

Are you pumping air or does the pump pump up to pressure and then loses it? Please give us more details. Regards,Tom

Hi Tom, The pump in the house will keep 50 lbs for a couple minutes and then drops to nothing.The pump and water line from in the house are full. We know it's getting air but don't know how or where from. We started digging to find the line andconnections to check them. So hard when we are all handicapped in one way or another. Doing it all by hand. If you have any answers please let me know of if we've done things right. Thanks

Good morning Teresa,

The pump in the house will keep 50 lbs for a couple minutes and then drops to nothing.

Two things will cause this, a faulty check/foot valve or a leak in the system. This can be checked by allowing the pump to pump to cut-off and then closing the shut off valve from the pump to the house. If the pressure remains then the problem is from the pump to the well point. The air in the system could be caused by, 1) the pump cavatating, 2) a break in the suction line in the well allowing air to enter, **or** 3) a low water table that's letting you pull air instead of water. ( Number 1 and 2 are connected) After checking, let me know where you think the problem might be. Good luck, Tom

Hi Tom, We got to the connection right at the cistern. It was leaking . So for now we tightened the screws until we can get our cistern down enough to change the valve. What a job,we just hope that's all it is(lol). We have another problem now though. The pump maintains 65 lbs now which is good, however,we don't have the pressure in any of the taps. Water definitely comes out but no where near the pressure we had. What could be wrong now? Thanks for answering my other questions. Teresa

Hi Teresa,

The pump maintains 65 lbs now which is good, however,we don't have the pressure in any of the taps. Water definitely comes out but no where near the pressure we had. What could be wrong now?

Your pressure should be good, you're 20 PSI above the average house pressure. However, I have a hunch that when you repaired the leak you disturbed some minerals built up in the pipe walls which got sucked up into your system.
Now the fun begins. First, remove the aerator and check the screens for trash from a faucet that's running slow. Can you get a full stream out of the faucet now? If not the water has to be shut off, the faucet opened up and the inlet ports of the cartridge cleaned. Now place a pan over the open faucet and turn the water back on for a minute to flush out the supplies and open valve body. Reassemble and move on to the next one. Do this with each faucet affected. Start with the faucet closest to the cistern, regards, Tom
