I took out the 1.25" steel well pipe and sand point and replaced it with a 1" pvc pipe and foot valve. I measured at least 5' of water. When priming it all I get is dirty water and the tank won't fill. I can only get 6 lbs of pressure. New pump worked good with the old pipe at first but then started sucking air and wouldn't hold pressure.
Thoughts?

1. Same pump?

2. Did you take out the old check valve, since a foot valve includes a check valve.

3. How big diameter is the well that you dropped the foot valve into?

4. How far off of the bottom is the foot valve?

So you can generate 6 psi, and get fairly continuous water?

You could have a vacuum leak, or you could have a clogged jet. clean jet pump venturi:

Let me see if I got that right... you pulled a sand point out of the dirt and stuck a PVC pipe with foot valve into the dirt? I would not expect that to work. The purpose of a sand point is to filter out the sand. A foot valve won't do that.

Oooh. I had not thought of that interpretation. That is scary. I was thinking there was maybe a casing or a dug well, and the sand point had just been a pickup.

It wasn't "dirt" before. There was 5-6 feet of good water. I know what a sandpoint is and what it does. I dropped a depth finder on a sting line down to measure water level.

New pump. No check valve. Pressure tank won't fill. Checked pressure for bladder. Made sure the 23psi was there. I suppose a bunch of sediment/sand fell down removing the old pipe
