CSV1A or CSV2W better for my application?
« on: May 05, 2021, 04:52:25 PM »
Hello

I have a Grundros 16S15-14 set at 150’ going into 1-1/2 cts poly traveling 500ft and about 50ft up in elevation to where I’m setting up temporary water for construction. I was planning on setting up a well X trol wx-202xl with a 40/60 switch. I would like to also incorporate a CSV into the system. Can you recommend which one? What kind of pressure should I expect at the pitless when the CSV is holding my pump back to 1gpm? I think the compression fittings for the poly are only rated at 125psi. Thanks

A 16S15-14 can build 173 PSI.  The pitless will see 1 PSI less than that for every 2.31' down to the static water level in the well.  Use long insert or barb fittings with two hose clamps instead of compression couplings on poly.  A 20 gallon size 202 tank is fine but is larger than you need when using a CSV1A valve.  You can get that $179 CSV1A in a complete kit including a 4.5 gallons size tank for $395.00 total.

50' of rise after the pressure switch and tank will take 22 PSI.  You might want to run a 60/80 pressure switch with the CSV1A set at 70 PSI to make up for the elevation rise.  At 60/80 pressure you will need larger than the 4.5 gallon tank, so you can use the 10 gallon available with the kit for an extra 50 bucks or go ahead with the 20 gallon tank you were thinking of.  You can also get the PK1ALT kit, which the LT means less tank, and attach whatever tank you want to the 3/4 port on the bottom of the CSV1A.

I’m having a hard time finding barbed fittings for the CTS poly I have ordered, and from what I’ve read CTS requires Ford or similar fittings. The guys at the waterworks store suggested the Mueller h-15451 and some nipples and bushings to adapt the 1-1/4 pitless to my 1-1/2 poly.  I ordered the poly from Home Depot and kinda regretting getting the CTS. I haven’t picked it up yet and I’m considering returning it..but it was almost impossible to find IPS in the length I need locally and the cost was substantialy more.

The switch and tank will be at the top of the hill and will eventually be in the garage of our new house.

With the switch and tank at the top of the hill the pressure switch will just need to be 40/60.
