@jeff5may:
I haven't had the time to give your suggestions a try yet, but may tomorrow. I have a check valve just below the ejector, which is offset from the pump about a foot. I can't recall if...

@simenad:
Have you measured temperature changes over time?
What is your tonnage and flow rate?
What kind of pump(s) are you using?
Does the injection well have any problem taking the water?

A submersible won't fit in 1.5" PVC... We'll just have to see how it goes. The pump is a Myers, so it isn't crap. Hopefully it'll get the job done.

So, cement set up overnight. We tried pumping from the well with the 2" trash pump, which didn't really work so well. Tough to prime, but we DID pull some water out. The...

Well, we have a problem.
Shortly after adding some kitty litter (bentonite) to help remove cuttings, our pump ran out of gas. I rushed to partially fill the tank, and in those down 30 seconds, we...

WSHP: Supply well and return well spacing?
