We have people constantly coming and going, so no doubt, infiltration is an issue.

High-SEER mini splits instead of WSHP?

I've had problems with my well drilling. While I COULD get a fair amount of sustained flow by starting over and going with a 4" diameter casing (to get an ejector inside) or 6" diameter (for a...

Well, I'm jealous! :)

I'm also surprised that you are getting the heat exchange that you need with whatever flow rate you get from the 1/2hp pump. For 15 tons of HVAC, I thought you would need...

@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?

Well, to do it ALL over, hiring a contractor may have been the way to go. But, on the 4' casing thing, my thought during posting that is that it would be removed; it would serve as a drilling aid,...

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.

There is no foot valve, but there will be a...

Unfortunately, yes.

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...

That's probably solid advice. I'm thinking if we were to attempt to simply go OVER the 1-1/2" hole coaxially, it ought to be fairly easy drilling.

Now, I made a really nice well screen about 22'...

WSHP: Supply well and return well spacing?
