Water pump is STILL constantly running! Since this past thursday, we did:new check valvenew pressure controlnew foot valve (well)well is not dryprime, air pressure are finewe have above ground pump in the basement. we called a plumber and he could do nothing! we have water and pump/tank and everything seem working fine.But the pump is on and off every 30 seconds - 1 minute. It is so annoying and out of ideas what could be wrong.My husband think it could be the tank and suggested that we replace it. But the plumber didn't say anything about the tank. And it is not too old.Do you think it is the tank and we need to replace it? If so, we will do it on this Sunday morning even though it might cost extra charge! please help!!!
If the pump is running it is being asked to from some where. The pressure switch is what calls for it to run when the pressure drops. So if the bladder in the tank was bad it could cause an insufficient pressure fall and that is asking for the pump to run
you have what is called a water logged tank!! that means you are not putting enough air into it to act as a pressure source for the water,, this makes the prsessure switch kick on and off constantly,, if you have a bladder in your tank you have to add air thru a bicycle like valve usually on top of the tank,, if no bladder then you have to drain all the water from the tank and then screw everything tight before you turn it on to refill with water!! the air in the tank will compress then!! or or pressure switch was not bled right!!!!
Reading through what you have replaced about the only thing it could be is you have a hole in the supply line somewhere. If the tank needed replacement, when there is no draw on the system, like when you get a drink of water, there will be no cycling of the pump. In other words if there is no spigot on then there must be a leak somewhere.
I had the same problem with this in my home and I fixed it by simply adding air to my pressure tank. where your well line comes in there you should have a water softener and filters and a tank for holding pressure in the lines. shut off the water to the house and start filling the tank with air until you get to around 46 PSI once that's done turn the house water back on. It should take a lot longer for the pump to kick on now. It's pretty easy and I would definitely try to do it yourself first before calling a repair man out. It'll save you a few bucks!
ITS A WATER LOGGED TANK, DONT REPLACE IT JUST DRAIN IT drain the tank, you need the air pocket in the tank. drain the pressure tank completely, let it fill it again, and have an air pocket in it. if it has a rubber bladder in it , the bladder could be leaking and all the air has been replaced with water, drain the tank and see if it feels empty after it is drained, if not the rubber bladder is full of water, new tank is needed. with no air pocket the pump is going to keep cycling on and off. the pressure switch comes on at 20 lbs, shuts off at 40 lbs. the only way it gets the 20 lbs difference is with the air pocket expanding. if all is well, lets say it takes 2 minutes for the pressure to drop from 40 to 20 with a faucet wide open. with no air pocket it will drop from 40 to 20 in a half a second, pump kicks on to pressureize it and its back to 40 in a half a second. pump is on and off, on and off over and over over. with an air pocket it will take the pump several minutes to bring it back up to 40 from 20.
