Irrigation system problem

My irrigation system will not work. The well has a new pump and supplies adequate pressure to the house unless an irrigation line is turned on. Each head only trickles a little and the pressure in my house drops to nothing. I don't suspect a leak because the well does not run unless a sprinkler line is running. The well pressure stays up in the 50 PSI range during this time but will not activate any of the heads. I cannot even get the sprinkler system to work manually. I do have one line that works and when the sprinklers are running, the pressure in the house is still good. It only dies down when a line is turned on but not putting out any water. Could this be a faulty gate valve that maybe blocking adequate flow of water to the sprinklers a creating some type of back pressure that stops the flow of water to the house? If anyone has seen this type of problem and has an idea I would appreciate hearing about it. Thanks.

How big is your pump? How much HP rating? It could be a case of blocked water line. Just check your pipe lines and the gate valve for blockage. Just your e-mail
for your comments.

Our auto irrigation system wouldn't turn off. We found the Davey XJ70 pressure pump was leaking so replaced the leaking pipe. Now the watering g system won't start. What do we do?

Hi Geralidine
Sounds like your pump is "air bound"...meaning that the impeller housing of the pump is full of air, and it cannot pump water.
Try bleeding the air out of the pump and put a positive pressure (garden hose pressure) and make sure that you shut the airbleed valve off after you start to pump.

The well pump is running, but no water is supplied to thr irrigation lines. once I put water in the pump housing by removing the pump guage the pump pumps water through the irrigation lines. when it shuts...

Sounds like you have an air leak. First check your fittings, next carefully run water over the pump seals (avoid getting water on the motor or you'll hurt yourself and the pump if not worse) the pump will prime if the leaking seal is covered with water. Take your time and be careful and it should only be a matter of a loose fitting or simple seal swap.

I have a lake house with irrigation system drawing water from the lake. The pump works. But there is a second primer pump that I do not know how to turn it on or how it supposed to work.

I used to take care of a system like that in the basement of a ten story college dorm. There was a big pump and a little pump. The purpose of the little pump is to maintain pressure when there is no usage of water. Then when a big demand comes, the big pump kicks in. I had problems with the
big pump getting hot, because the controls didn't work right. I unhooked all the controls and strapped a heat sensing aquastat box to the discharge pipe. When the water got hot, this state
would open a tiny little solinoid valve and dump enough water down the floor drain to keep the
pump cool.

I have a 1/2 hp pump which I use to pump lake water to my irrigation system. The pump takes too long to turn on when the spicket is opened and sometimes too long to shut off when the water spicket is...

when using the spicket you use less flow than your irrigation system so a delay in the pump coming on is normal...otherwise if you are having the same problem when the irrigation is running..a pressure switch adjustment may be necessary...please follow the manufacturer instructions for your pressure switch.
