Well Pump Problems

I have a sand point well at my cottage. The pump is located approximately 12 ft away from the well. Its driven 25 ft into the ground and water is 15 ft down. I had bought a cheaper 1/2 hp diamond pump and it was difficult to prime and draw water with a 1 1/4" inlet pipe. We spent two days working on it when finally it was decided that we would purchase a 3/4 hp c series jacuzzi pump. (top of the line I am told and at this time wanted to make sure it would be the right pump) I have water but it draws some air. You could see bubbles come into the clear pipe that feeds the pressure tank Worst of all it kicks (shakes) twice when it finishes its cycle. Is this normal? I have checked all connections it does not take air in at the pump or at the check valve. The check valve is located at the well. I am concerned that going with a 3/4 that the pump may be outproducing the well. I was told to relocate the check valve at the pump!!?? Install a "air vent" to have air released from the system!!?? Thirdly I was told to reduce my water line thickness from 1 1/4" to 1"!!?? Where do I go with this. Did I buy the wrong pump. I have balanced the pressure tank. It starts at 30 psi and I have it shutt off at 40psi. Thank you.

No it is not normal. Air is either coming from a leak in the suction line, a clogged well point, or too low of a water level. Adding an air relief won't help.

is the pump overpowered or is this irrelevent

Still sounds like a suction leak. Probably the reason it was hard to prime. Smaller pipe won't help. Pump could be trying to draw more water than it can get but, it wouldn't just stop pumping at 40 PSI. You can choke the discharge of the pump back with a ball valve. This will simulate a smaller pump but, will probably make the problem worse if there is a suction leak.

well problems

Thank you. I am going to try and reseal the connections at the well and pump. I wlll choke back at the discharge. Should I change the settings back to a 30/50 psi rather than the 30/40 psi I have it set at.

Thank you for your Help

I have fixed the kicking problem. I have lowered the settings to a 20psi start and 40psi shut off. For some reason it runs very smooth now and does not kick at the end of its cycle. Still taking in air however. It could be a blocked screen. How well do these nu well tablets work and where can you get them in Canada? Once again thank you

Do a Google search for the Nu-Well Tablets.

Whether the screen is plugged or not, air has to come from the suction line, so you still have fittings that are not air tight.
