Possible to run 2 cycle stop valves in same system?

[GloNDark]

I bought a house last year and it has a the PK1A valve setup for the house. I love it for the house.

But the original owner plumbed the irrigation in BEFORE the house. It's been running like this for nearly 8 years. The lawn sprinklers will kick the pump on and keep it on while they are running. But the drip systems (4 of them) will not.

So my question is this: I know that I can install a CSV125 in a box underground outside of the well head and then remove the PK1A in the house. But can I install a CSV125 in line with the irrigation only and still keep the PK1A in the house?

I'm going to dig up my sprinkler main shut off and replace it due to it leaking and was thinking if this will work, it would be a perfect time to get it done.

There are a couple different ways you can skin that cat.  lol

Yes you can install a CSV125 or another CSV1A prior to the first tee.  And yes you can leave the CSV1A where it is, just need to tighten the adjusting bolt a few rounds so it doesn't do anything.  This way the CSV1A is just being used as a manifold for the tank, switch, gauge, etc.

Or you can install a manifold in the house for the tank, switch, gauge, and move the CSV1A outside and put it in the valve box before the first tee.

hhhmmmm Awesome. That gives me a couple of good ideas.

Thanks! i'm looking forward to not having to stress about my pump with the drip system comes on. hahaha

This is the way we do it when the CSV1A needs to go out by the well and everything else in the house.

I posted a while back about this and I finally got to pulling my pitiless and installing the Cycle stop valve at the top of my well head. Now I’m trying to adjust the Cycle stop in the well closet to make it work properly and I can’t seem to figure it out.

If I back it out it drops the pressure down to 30psi but it doesn’t cycle the pump on and off. If I screw it’s in to bring up the pressure it goes to cycling the pump on and off/on and off. I can’t find a happy medium. Any advice?

I figured it out (I think haha). Backed out the adjuster on the CSV1A until the pressure started dropping but the pump stayed on. Then slowly increased the pressure until I found the happy spot for it. Able to go,d right at 50 psi without the pump cycling. I can run all my irrigation with the same results.

Sooooooo stoked!  Now to order a new pressure tank since the one the well guy put on there is way too small. I had 4.5 gallon that worked great but the bladder failed and when I had the pump replaced they put a tiny tank on there. Now to decide between the 4.5 gallon or the 10 gallon tank. Hmmm

Maybe I don't understand?  Do you now have two Cycle Stop Valves?  Is there one in the well and another in the closet?  If so the one in the well is the main control and the one in the closet needs to be tightened down a few rounds so it can't work.  If you have one of the non-adjustable CSV's in the well you just need to turn up the pressure switch to make it work and prevent cycling.

Originally there was one in the closet, that ran the house. But all the irrigation was before the CSV. Now there is the CSV at the well head and he one in the closet in the house. When i first turned it all back on, it would rapid cycle, down to 40 psi, up to 60 psi, rapidly. Like twice a minute.

I tried adjusting the nut in and it only got worse.  So I backed it out until it would just run without cycling and slowly adjusted pressure up until it was normalized.

Our pressure tank was bad when the well pump died. And the well guy put a 1 gallon tiny pressure tank in there. Not sure that has anything to do with the rapid cycle though

I am guessing they put a 60 PSI valve in the well.  With your 40/60 switch the pump shuts off before that CSV can work.  Tighten the big screw in the pressure switch until the pump shuts off at 70 instead of 60.  Then tighten the bolt on the CSV in the closet 3-4 rounds to the right and try it again.

Thanks Cary, I will try that tonight when I get home. If it makes a difference here is that 2 valves i'm working with.


This is what is what is installed at the top of the well as of yesterday: https://cyclestopvalves.com/pages/csv125

And what was there in the closet already: https://cyclestopvalves.com/pages/pk1a-pside-kick

[Cary Austin]

Those CSV125 valves that go in the well come in 40,50, or 60 PSI.  60 PSI is the most common to put down the well.  Just means you need to turn the pressure switch up to 50/70 to make it work.  Then tightening the adjustment bolt a few rounds on the above ground CSV1A wiil make it work like a piece of pipe, and the CSV125 in the well will be doing all the work.
