In well csv

[Kristo89]

I’ve been looking at either converting my well pump to a vfd or installing a csv. The issue that I’m running in to is that my well supplies my house and my workshop and they are connected underground just outside the well casing. In order for the csv to work for me I believe I have to have it installed between the pump and the tee that joins the two water lines to the casing outlet. Is there a csv available that will fit in a 4” well casing?

Yes.  The CSVS125 can fit in the well just below the pitless adapter.  You can see it here.

Awesome! That should work perfect. I’m thinking of ordering the 60 psi valve. Right now my pump switch is set for 40/60. I’m guessing that I’ll have to adjust it up to 65?

Pressure switch off at 65 PSI would be right with a huge 80+ gallon size pressure tank.  With a smaller tank You will want a 50/70 pressure switch setting.  We also need to make sure the pump you have cannot make more than 150 PSI as that is the limit of the CSV125.
