Hello, I have a pump that feeds my house from a well. I contast that this engine will start only a few seconds and that even when we do not have water? Can you tell me if this can come from a drain or drain poorly done? In this case it is possible to know how to drain this? Thank you very much in advance for your help

If you have a large tank 200 to 300 L there is a possibility that the it does not contain enough air to prevent short cycling of pump, the pump stop solution, flush with water and once it stops running, open the cap or valve on top of tank

Then let drain naturally by a tap
when a significant amount of water is out, replace the plug, shut the faucet and put the poem on.

If you have a diaphragm tank (such as expansion tanks) to check if the pressure is good air side is good

other hand the fact that the pump operates from time to time indicates that there may be a leak in the water system

here is the solution for which I chose my home.

I a water tank of 200 liters and I had the same concerns.

So on top of the tank I removed the cap and y and m ' a valve there.

when my pump starts up too often, lack of air in the tank, I cut the pump I empty the tank completely by drain valve at the bottom and once all this closed valve on my top, I plug in my compressor.
and I put 2 of 1 bar air pressure.

then I redo the valve and restarts the pump

Good evening

I confirm the version of MUF for bladder tanks, except that I put 0.200 g less than the minimum pressure of starting. For 1.8 or 1.6 bar.
For the version without bladder Mareson is certainly right.
