Could use some tips on debugging Lake Water pump

All fixed.

When looking last night I was surprised how shallow the pickup was at and figured that caused it. This morning I cut off the end and added 8 feet and a new foot valve.

I go to prime it and water is pouring the back. It was disconnected!
So I reconnect it and it just won’t prime. Just won’t get above 25lbs. But every time I shut it off I hear a little gurgle where I reconnected. So I replaced the whole section which had a couple unions. The tubing they used was 160psi the stuff I bough was only 100psi.

After that it primed right up. No more back pressure leak.

There was an odd cut in the line right near the foot valve which I think was the back pressure leak.

Now it only runs when water is used. Amazing the pump still works.
