Valve Tech / Re: CSV 125 50psi failing
« Last post by ron958 on June 17, 2023, 01:05:01 PM »
Thank you for the prompt reply. I will post pictures of my system later. There are no mechanical restrictions in the water system anywhere other than manifold and valves, all of which have not been changed or modified. Only two check valves, the one built into the pump and another brass 1 1/4” check valve directly above the pump as a back up. 1 1/4” PVC  line from pump to CSV valve and 1 1/4” PVC line existing.
There is a factory installed fine mesh  screen surrounding the inlet of pump which is unobstructed.
Internal openings in the CSV must be quiet large if it’s rated capable of passing full flow of 12 GPM pump?
Can the CSV be removed and back flushed? Are all the internal components stainless?
Gauge working as pressure fluctuates between 120 and 50 PSI and down to 0 if pump is shut down,  depending on how water system is used.
Pressure gauge is on main line 6” below CSV, between pump and CSV.

It is almost impossible for the CSV125 to fail in the closed position.  It could have something inside of it blocking flow, but the valve cannot physically fail closed.  Maybe the inlet pressure gauge is pegged and reading 90 PSI more than it should.  It could be a check valve by the CSV failed in the closed position?  Post a picture so we can see the set up.  No problem sending you another CSV125 if that is needed, but really need to find the cause of problem first.

3/4 sch 40 pipe has an operating pressure of 289 PSI and a burst pressure at least twice that much.  Your 1/2HP pump will only be able to make about 100 PSI back pressure.

Valve Tech / CSV 125 50psi failing
« Last post by ron958 on June 15, 2023, 11:13:31 PM »
CSV 125 50 psi is failing closed. Valve about 4 yrs. old and no longer allowing full volume of pump to flow through valve. Pump is 3/4 hp rated at 12 gpm approximately 30 deep in the well. In the past could easily handle 2 lawn sprinklers and any water demands in the house. Lately with 2 sprinklers  going, the max pressure capable slightly above low pressure cut in 32 psi., and if any demand for water is made in the house the volume of water can’t keep up, pressure falls below low cut off and system shuts down. Back pressure between the pump and valve 120 psi. Volume no longer going through valve to meet demand.
No changes made to water system since valve installed. Any thoughts to solve issue?

Cary,
The plumbing that runs to the well head is 3/4" sch 40 PVC I assume that it will be able to handle the expected back pressure from the CSV?

Cary,

Thanks again for the detailed reply. I will see if I can figure out the gpm for the drip emitters. In the meantime, I'll set the rapid cycle sensor to 35 seconds and get a CSV1A ordered. BTW if in the future when the pressure tank needs replacing which of the I purchase the pressure tank kits would I need?

Regards,
Lou

You need to add up the drip emitters and see how many gallons per hour you have and translate to gallons per minute.  My guess is you are not even using 1 GPM, which is 60 GPH.  IN that case the 45 seconds you have set in the Cycle Sensor for rapid cycle fault it too much. With no other water running the tank fills faster than when a faucet, shower, or other device is using some water.  Just turn down the rapid cycle setting to say,35 seconds until you get the Cycle Stop Valve installed.  With the CSV installed you can make it take as long as 8 minutes to fill the tank and shut off. 

The 32 gallon size tank only holds 8 gallons of water.  The 10-12 GPM pump is filling the 8 gallons in the tank too fast, and causing the Cycle Sensor to detect a short run time and shut the pump off.  The CSV will only fill the tank after all water uses are turned off, and then it will only fill the tank at 1 GPM.  To get about a 2 minute run time to fill the tank as needed, we just set the CSV1A for 55 PSI to work with your 40/60 switch.  In this way the CSV gives 55 PSI constant, and only takes 2 minutes to fill the tank after water use stops.

Just cut that 1" PVC pipe right where you made the red arrow that says "from well".  Screw a couple of 1" PVC male adapters to the CSV1A and glue it in that place.  Order it preset for 55 PSI and your done.  Or set it yourself to 55 PSI with a shower running.  You will like that strong constant 55 PSI when you are done.

Oh yeah, then reset the rapid cycle feature in the Cycle Sensor for about 90 seconds because the rapid cycle problem will have gone away as well.

Cary,

I don't believe that the output from the drip system would exceed the well capacity. We're using 5/8" tubing with drip emitters, not an actual sprinkler type system. I turned off the drip system last night and this morning there were no issues, so it appears that it is related to the drip system.

I'm looking over the website to see what would work for ourt application, that is, just a cycle stop valve with our older existing pressure tank, or a complete pressure tank/CSV kit.

I was eventually going to replace the 36 gallon pressure tank, but it's hanging in there. I'm attaching a couple of pictures of the current plumbing setup. If you could recommend which CSV I would need, and if I went with a full system which Side Kick kit.

Thanks,
Lou

A high peak amp draw on start up is normal.  The 15 PSI regulator is common and not important.  What is important is the GPM of the drip system zones.  Are the zones larger than the output of the well is the question.

A Cycle Stop Valve would help as 2-4 minutes between cycles is a lot of cycling, which will destroy the pump, tank, switch, check valve, and other things.
