Valve Tech / Re: CSV 125 50psi failing
« Last post by Cary Austin on May 10, 2025, 10:12:18 AM »A 12 GPM pump will actually put out about 17 GPM running wide open like that. Again, below 50 PSI the CSV is just a piece of open pipe.

« Last post by ron958 on May 07, 2025, 03:31:00 PM »If I understand you correctly, using an 1 1/4” hose with 1 1/4” valve on the outlet of the CSVS 125 50-1 should allow the pump to develop its full potential of 12 gpm? The CSV valve is at the top of the well, the pump approximately 20’ deep in the well with a 1 1/4” pvc line between the pump and the valve.

With the CSV installed you cannot test how much the pump will produce because the CSV will only let out as much as your faucet will at 50 PSI. The faucet only lets out 5 GPM at 50 PSI. If you open enough faucets or big enough valve to get the pressure down to 40 PSI the CSV will be wide open and you can test how much the pump is producing, just not from a single little faucet. The faucet is restricting the flow, not the CSV.

« Last post by ron958 on May 06, 2025, 05:46:02 PM »Looking to get more volume using CSVS 125. Pressure is fine no issues.
Test is to determine gallons produced by a 12 gpm pump in one minute with the CSVS in the piping system and when the CSVS is removed from the piping system. Container used to measure was a 5 gallon pail.
1 minute of unrestricted flow, tap wide open, with CSVS 125 in water line, 5 gallons.
1 minute of unrestricted flow, tap wide open, without CSVS 125 in water line 10 gallons.
Question is, does the plastic restrictor on the inlet side of the valve restrict the flow to 5 gallons per minute.

The 120 PSI back pressure just means you could open another faucet or two and still have 50 PSI constant as the back pressure comes down to signify more usage. All you are testing is how much water can go through the hose bib at different pressures. At 50 PSI constant you can only get 5 GPM through the hose bib. Without the CSV the pressure is higher and you get more flow through the hose bibb. But if you restricted the hose bibb to 5 GPM as before, the pump would cycle on and off without having the CSV.
Re-reading back to 2023, I don't think there was a problem there either. When running two sprinklers the pressure dropped to 32 PSI, and I don't see how the back pressure could have been 120 PSI. That is because when you open enough hose bibs to get the pressure below 50 PSI, the CSV just turns into a piece of pipe. At 32 PSI the back pressure should have been about 40 PSI because you were using all the water a 3/4HP, 12 GPM pump could supply.
If when you open enough hose bibs to bring the pressure below 50 PSI, the back pressure on the CSV should drop to almost the same. As long as the CSV is holding 50 PSI as it should, it is doing its job.
Now if you want more pressure the CSV125 also comes in 60 PSI, but I think you are out of pump and need a larger one for what you are doing.

« Last post by ron958 on May 05, 2025, 07:36:26 PM »I received the CSVS 125. Thank you. The new valve was placed in service with the same results.
Using an existing hose bib at the well head and isolating the rest of the system, timed how long to fill a 5 gallon pail.
Manually start pump, back pressure 120 psi. open valve, outlet pressure 50 psi.
After 1 minute 5 gallon pail full.
Removed CSVS 125 from the line, repeated same test, same equipment.
After 1 minute two (2) 5 gallon pails full = 10 gallons
Replaced CSVS 125 valve conducted another identical test. Same results 1 minute one(1) 5 gallon pail full.
Nothing between CSVS 125 and pump except check valve at top of pump.
Pump 3/4 hp 12 gpm.

« Last post by Cary Austin on March 31, 2025, 01:52:44 PM »Yes, you can easily add a pump to boost the 44 PSI gravity supply to 60 PSI or whatever you want. But we would need to know the flow rate required by the "high flow" demands to size a pump.

Pumps, Wells, Tanks, Controls / Booster Pump
« Last post by Winesalot on March 29, 2025, 11:31:53 AM »Here is my setup: Well pump feeds a 3800-gallon cistern on the high-elevation portion of our property, which is 100' in elevation above our commercial/residential building. The building is fed from the cistern with 2" white pipe, and I get the expected 44 psi at the building. The 2" pvc feed from the cistern is converted to a 1-1/2" Uponor PEX main header that runs the length of the building with tee's supplying all the various water needs.
I would like to boost the building's pressure to 60 psi. We have a commercial hot water dishwasher, and it just barely meets the minimum pressure required. (We Occasionally get a low-pressure error code.) We also find on our wine production crush pad that our garden hoses feel like they have a bit of a weak stream.
It seems logical that I would install a booster where the water comes into the building, where the pipe converts from 2" PVC to 1-1/2" PEX. The pump would only need to increase pressure by 20 psi but would need to meet the potential high-flow needs of a wine-tasting room, wine production space, and a three-bedroom residence.
I'd love to hear your thoughts.

Valve Tech / Re: Pressure between the pump and CSV
« Last post by Cary Austin on December 09, 2024, 08:53:17 AM »With the CSV1A adding additional back pressure it can make the pump think the well is deeper. So, you should be fine as is. But if you get a chance to change it the 1HP motor is fine, even with a 3/4HP pump end. You could put a 10 GPM, 3/4HP pump on the 1HP motor, or replace the 10 GPM, 1HP pump end with a 15-18 GPM, 1HP pump end.

« Last post by Mike56 on December 06, 2024, 02:33:19 PM »Thanks, Cary. The well guys put this in because that's all they had on their truck, saying it would be no issue. I suspected it wasn't right. They replaced a 3/4hp, 10gpm. I need to have this corrected to a 3/4 or even 1/2hp with this well setup, correct?
