Hello. I currently have a 1HP 20GPM pump set at 165'. It's not really designed for that depth so doesn't pump down anywhere near that far. The water table is typically at about 35' so it does put out a lot until it drains the well down, but not anywhere near the pump depth. I put it in about a year ago because my pump had failed and it was all I could get really quick - and it was cheap at Home Depot.
Anyhow, I'm considering buying another pump as a backup and am not able to buy a really expensive one like a Gould. I do a lot of irrigating around the house (big garden and do yard too) so I want a pump that will output a lot. I'm looking at a Tuhorse:
http://www.tuhorse.us/submersible-p...-complete-pump-end-motor-control-box-pro-set/
I figure it should easily handle the depth and still be pumping about 26 or so GPM at that depth, or close to it. One reason I'm looking at this pump is because I may also have the well deepened to 300' and fracked later on with the pump setting at 280' whereat, it should still pump about 13 GPM.
I said all that because I have a question concerning a CSV. I currently use one on my 1HP 20 GPM which isn't rated for much depth and a pressure gauge right off the pump shows it goes to just over 100psi when it turns on and then the CSV holds it at about 85psi while water is running at at least 3GPM and on the pressure switch side of the CSV shows 50psi (the switch is set at 40 on, 60 off, and so I've set the CSV to hold it at 50psi). So, my question is concerning what I assume will be MUCH higher pressure on the pump side of the CSV with the more powerful pump and wondering how I deal with that pressure. Should I add a 100psi or so pressure relief valve at the top of the pipe so it can just blow back into the well? Any suggestions of corrections of my assumptions?
Thanks,
Tim
