I share a well with my Mother. The line T's off to my place it is 350' to my place with its own shut off vaulve. PROBLEM....Water runs for a time then stops running. Thought it had to do with old galv pipes, put all new plumbing in under house..still doing it. Then ran hose from my mom's outside spicket to my house thinking the line underground might be clogged with a loose scale deposit floating...still stops running????? Suggestions???? What else might we try???? During all this my Mom still has water running at her house. We also put a new pressure tank at the pump house and a new hot water tank at my place. One more thing... When the water does stop if we turn the spicket on just above the main water line it will work good there and within seconds the house water comes back on???? Were at a loss for a soultion any suggestions...please let me know......

Thank you so much!!!

Where is the presure tank? Where is the pressure switch?

What is the elevation between where the pressure switch is and where your mothers house is and where you house is?

And when this happens what is the pressure like at your mothers house?

When this happens read what the pressure is at the pressure switch both when you don't have water and when you do.

My guess is that the pressure is too low for it to make it too your house.

Thank you for responding....

The pressure tank is a few yards from my Mom's in a well house and 250' of hose to my house. The pressure switch is right off of the tank. We have already checked the pressure tank pressure, it will only go to 60 psi and we have it 55. When I have no water my Mother's if fine.

The stumper is when the water does stop at my house and we turn on the spicket that we put on just above were the main water line comes into my house it will imediatly start running again and there is no delay at that spicket....

I wanted to put a seperate pressure tank at my house, but my Uncle says that will confuse the well pump.(250' away???) He says we need to perhaps install a bladder??? Cost wise the pressure tank is less and would give the pressure at my house. What do you think??? Is there any way if it is the pressure to boost it without costing an arm and leg???

Thank you again,

Is your house at a higher elevation than your mothers, if so about how much?

When you open the spigot that starts the water flowing again just what happens? Do you get air coming out of the vavle first?

The next time that this happens and before opening the spigot run down to the well tank and see what the pressure is reading.

Are there any pressure reducing valves in the system any place? Where?

Likewise any check valves.

In general a pressure tank at your house won't do anything. In a few cases they can be helpfull. One is if the supply to your house is too small so that you have pressure until you open a valve and then it quickly drops off. The other cases is if you have wildly functuation pressure and then you would need also need a check valve.

Basically the well and tank that you have is nothing more or less that what cities have, but on a very small scale.

BTW, pressure tanks come in two versions, one is plain and the other has a blader in it.

Both use air pressure to cushion the water and provide pressure to for the water when the pump is not running. The bladder tank version has a rubber blader between the air and water and it is a better unit. It keeps the water for absorbing the air (and thus aire needs to be added or a an air control vavle is needed) and it allows the tank to hold more water than the same size plain version.

Typically there is a 20 psi difference between the pump shut off and start. If yours is set to shutoff at 55 then it would start about 35 psi.

When some one uses water the air pressure will push water out of the tank and cause water to flow. Then the pressure will slowly drop down to 35 and the pump will start.

A common problem with wells is if the tank air press and the pressure switch are misadjusted to each other then the air pressure in the tank can fool the pressure switch and the pressure stays up until the last drop of water runs out of the tank. Then the pressure drops to zero and the pump starts.

I have a feeling that is what is happening with you. But it does not follow the symptoms that your mother still has water. That is unless you house is much, much higher than hers.
