New pump problem

[NH Handyman]

Two line system - I replaced a 30+ year old 1/2 horse pump and 19 gallon tank with a new 1/2 horse County Line pump and AO Smith 32 gallon tank. The old pump sat on the basement floor next to the tank. I mounted the new pump on top of the new tank, extended the lines with a combination of black poly and PVC. The pump runs and is moving water but builds no pressure. I have checked all the pipe connections 3 times. Where clamps are used, I used two had heated the poly so it would clamp well. The pipes are full of water and they don't leak down. I need some help. No water going on 3 days....

Sorry for the delay. Raising the pump off the floor a couple feet shouldn't hurt with a deep well jet. But the plastic union on the suction line is not good as is can be a place for a suction air leak. It looks like there is a flow control valve on top of the pump. You should try adjusting that to get more pressure. If that valve isn't working closing the discharge ball valve about 80% will probably work just as well. Got to hold back some pressure to make the jet at the bottom of the well work. But best guess is a suction leak. Something clogged in the jet nozzle will also cause low pressure.

No pressure? Try closing the valve that feeds water to the house. Then watch the gauge more carefully as you run the pump.

Your third photo seems to have pressure indicated on the pressure gauge.
