I have a new 540' well with a 4" PVC liner that will be serving a four bed, three bath house with two yard hydrants, and I'm deciding what kind of down pipe to use.
My current plan is to set a 2hp pump at 480'. That was the driller's suggestion, sounds good to me, but I'm not knowledgeable enough to be married to those figures. The static water level was at 255' down, and I don't know what the recharge rate is.
I would be comfortable with 1 1/4" schedule 120 PVC (300 psi) for the down pipe. But I prefer continuous roll pipe over segmented straight pipe, partly because I can get a 500' roll of tubing and not have joints every 20', but mostly for installation and pulling the pump. With appropriate rollers I expect to hitch the pipe to the back of my pickup and take off down the yard when the time comes to pull the pump, similar to the way I've pulled aerial cable in the past.
The sch 120 would cost me about $1.89/ft, which is pretty similar to what I expect to be able to get the roll poly pipe for. BUT, the poly pipe isn't rated for such a deep application. And there seem to be a lot of variations of potable polyethylene, or high density polyethylene, HDPE. As an example I see Menard's offers a 500' roll of 1 1/4" SIDR 7, 250 psi poly pipe for about $900. I don't even know if that's suitable for down-hole usage, but it seems to have similar characteristics anyway, and the 250 psi rating is a little better than the 200 psi rating of some similar poly pipe.
So my first question is what's the strongest poly pipe I could use, is 200 or 250 psi the best there is for a comparable price?
If that poly roll from Menard's isn't appropriate for the application, what specifications am I looking for?
And I've seen some discussion of the different pipe types on here, so I'm seeking input from people with actual experience with poly pipe at depths approaching 500' with a 2hp pump.
I would also appreciate a little input on proper connectors because I'm not familiar enough with CTS, NPT, IPS, SDR, SIDR, etc to know what fittings go with what styles of pipe. I expect to use long barb stainless or brass fittings, but if I should be looking at different connectors like pack joint fittings please let me know.
And I'm just expecting to install one check valve near the pump, which brings up the subject of a weep hole between the pump and check valve, because I noticed Hallmark recommends one, but the idea of pumping water out a hole in the side of the pipe seems counterintuitive to me.
Many thanks,
Bill
