    Need help troubleshooting low pressure

    Problem solved, I pulled the jet and nozzle replaced it with the next size bigger. The pump now cuts out at 52psi and cuts in at 32 psi and with the sprinklers running pressure stays above 30 psi. The well is working great, thanks for all the help. Pete

    Need help troubleshooting low pressure

    I tried to add back pressure by slowly closing the ball valve, the pressure did not go up until I had the ball valve 3/4 of the way closed. At that point the pressure went up to 30 PSI but the sprinklers were only spraying about two feet. The pressure tank was empty. I will pull the injector...

    I will try choking back on the ball valve, will this help with the volume of water. When I tested the pressure was ok until the pressure tank ran out of water then the pressure dropped instantly to 10 psi. I could feel the tank when it ran out of water. thanks, pete

    Need help troubleshooting low pressure

    I will check the tank pressure when I get home today. I will also run a test with the pump running and the pressure at 40 psi I will turn on the sprinklers and see if the pump can maintain close to the 40 PSI or if it drops immediately to 10 PSI like it does when the pump cuts in at 30 PSI. I...

    Need help troubleshooting low pressure

    There is no regulator the two pipes that go down the well are connected directly to the pump, which is only 1' from the well casing. Should I install the bigger or smaller nozzle to get more volume, I do not have the old injector anymore.

    the pump has no label on it. The regulator (the part that controls the cut in and cut out)is on the motor, and the gauge is on the pump.It has worked fine for me for the last 15 years.

    The deep jet motor says on it 1/2 HP manufactured by GE. This is an old pump maybe 20 years old. The new injector I bought came with 3 nozzles I think a 51,52,53 I used the 52 and the venture that went with the nozzle per the instructions. I can pull the injector back out and change the...

    Need help troubleshooting low pressure

    I will try and let some air out of the tank. How would too much precharge in the pressure tank cause the symptoms I have. Just trying to understand a little better. Thanks, pete

    Need help troubleshooting low pressure

    I have a deep well jet pump used for irrigation. I just replaced the injector at the bottom of the well because I could not get more then 35 psi. Now the pump shuts off at 50 psi and cuts in at 30 psi, the problem is when the pump cuts in at 30 psi and the sprinklers are on the pressure drops...

    Help replacing deep well injector

    I just pulled the pipe out if my well to inspect the injector. I have a GE 1/2 HP deep well jet pump. The water level is at 18 feet, the injector and the foot valve are at 25 feet. After doing some research, I read that the injector should be 5 feet up from the foot valve. Does this mean when I...

    Well pump will not build enough pressure to cut out

    Does all the water go through the 1/4" hole in the center of the funnel? Does some water go around the outside of the funnel?

    Well pump will not build enough pressure to cut out

    So if the 1/4" hole is open the injector is good? Pete

    Well pump will not build enough pressure to cut out

    Ok I pulled the Injector, what I see is a small plastic funnel on the 1 1/4 line. There is a 1/4" hole at the bottom of the funnel. There is sand packed around the plastic funnel. This is the first time I have seen an injector so I am not sure how they work. Is the water pulled up through the 1...
