Pumps, Wells, Tanks, Controls / Low pressure due to low flow?
« Last post by john98266 on August 24, 2023, 06:08:19 PM »HELP! My system is a 78' well with a 1/2hp F&W 11GPM pump at 70'. I have a CSVS125-1 installed in the well at the pitless adapter. The pipe from the well to the manifold is 195' of 1-1/4" Pex. Past the manifold is a Kinetico water softener system. From there, there is a 1" poly pipe approx 50' to the 3/4" connection under my manufactured home. The CSV is set for 50lbs and the pressure cut-off is at 40-60lbs. I have checked the pressure at the hose bib in my shop (where the manifold and softener systems are) and it is 60psi. The flow at the hose bib in the shop is about 6gpm. When I turn on the faucet to water the lawn, the pressure drops to 40psi or lower if any other water is being used. This is a new home and I'm not sure where to start looking. Maybe a bigger pump? The wiring was installed to handle the amperage. I'm open to all suggestions.

Valve Tech / Re: Sizing CSV for well
« Last post by Cary Austin on August 21, 2023, 12:07:10 PM »With only a 5 GPM pump your pressure problem could be from a lack of flow instead of pressure. A 10 GPM, 1/2HP would be a much better fit for such a shallow well. A 3/4HP, 10 GPM would be even better.
But you can get what you can get with the 5 GPM pump. That pump lifting from 17' can make 155 PSI, which is 5 PSI higher than we recommend for the CSV125. We have some fudge factor figured in, so it will work. But the higher the pressure setting the better. You can use a 50 PSI in the CSV125-1 with a 40/60 switch. But you have plenty of pump pressure to turn up the switch to 50/70 and use a 60 PSI CSV125-1. If the 5 GPM volume is not your problem, the 60 PSI pressure would be such strong shower pressure than soap would no longer be needed. Lol!

Valve Tech / Sizing CSV for well
« Last post by Andrew12 on August 20, 2023, 11:57:49 PM »Hey
Been reading a bunch of posts here, think I have it somewhat figured but looking for some guidance. Looking to get a more ‘constant’ pressure from my well. Current setup is a 40~ gallon pressure tank, Franklin 1/2hp 5gpm submersible. 30/50 psi pressure switch. All located in the basement of the house. Going to be trenching over to a barn in the next couple weeks from the well, teeing into the existing line/hydrant. Well is 105’ deep, pump landed at 85’, static water level 17’. Pitiless adapter at 10’. Flow tested the well at 5 gpm. Looking at the csv12550, would you recommend leaving pressure switch at 30/50 or going to a 40/60? Or would a csv12560 be better with a 40/60 pressure switch. Looking for 40-50 psi for showering etc. Thanks in advance!

But a 12 GPM, 1/2 HP is a 12 GPM, 1/2HP and there isn't much difference between brands. Can't find a pump curve anywhere. But from the stupid chart I can see it matches the numbers of other such pumps so the max pressure will also be the same.

It is this pump:
https://www.zoellerathome.com/wp-content/themes/zoeller/content/literature/025095-Zoeller-4inSub-Instr-2-wire_190128_100819.pdf
Model #1450-0011
If I read the performance chart right it should be capable of 40 psi and ~9GPM at 65ft. Static water level is ~20ft.
I don't know how this translates with the CSV1A between the pump and the tank tee running @50PSI.
I'm using 160psi poly so I don't think I am stressing it.

Frequently Asked Questions / Re: Can I install this after a hose outlet?
« Last post by Cary Austin on August 19, 2023, 10:42:10 AM »Adjust the CSV down a bit first. That way it will take longer to fill the pressure tank and you can recalibrate the Littlefuse thing while the tank is filling. It will be running at the lowest amps while filling the tank and hopefully the Littlefuse will adjust low enough to work. If not, we made the Cycle Sensor to be infinitely adjustable for this reason. Some pumps will drop a lot more in amps and the Littlefuse and other similar devices that are set at 25% amp drop just will not work.

I looked up a 12 GPM, 1/2HP Red Lion pump and it can do max 240' of head, which is the same as 103 PSI. You can deduct from that 1 PSI for every 2.31' it is to the static water level. If it is 23' to the water level you will have 93 PSI max at the surface.
