Frequently Asked Questions / Re: Can I install this after a hose outlet?

Yeah those inserts in 3/4 pex make it work more like 1/2" pipe.  More pressure will squirt more water through the small lines.  78 PSI constant will make a lot of difference.  It is your water system.  No sense in putting up with "weak" pressure.  You can have as much pressure as you want, you just have to make it happen.  Adding the CSV1A and setting it at 78 should be all you need to do to have such good shower pressure that you don't even need soap anymore.  Lol!

You can certainly do that.  Placing the CSV1A at the pressure tank will let you set it for 78 when using a shower, and the irrigation teed in prior to the CSV will still work as normal at 65 PSI.  You actually want the CSV set at 78 when using a large tank and a 60/80 switch.  However, when the irrigation is not running, the back pressure from the CSV will be on the lines prior to the CSV, including the irrigation lines to the solenoid valves.  The back pressure will be as much, but also no more than your pump can produce.  You may want to figure the backpressure of your pump because of this.  Horsepower, GPM series, and depth to water is all you need to figure back pressure.  I can help if you feed me the numbers, or I can help you figure out those numbers.

In your second scenario of placing the CSV at the well, here is what happens.  Since you have already matched all your irrigation zones to the output of the pump at 65 PSI, installing the CSV1A prior to the tee to the irrigation will cause a 10 PSI loss at 20 GPM flow.  When everyone of someone's irrigation zones are small and cause the pump to cycle on and off, the friction loss of the CSV1A is a moot point.  They will never see a loss of pressure.  But if one of there zones is already maxing out the pump the way yours does, they see a 5-10 PSI loss on that zone.

A third option is to install the CSV125 or CSVS125 in the well or at the well head.  These valves have so little friction loss that zones matched to the pump will only see a pound or two loss.  However, they are not adjustable and the highest pressure unit we make is 60 PSI.  Therefore all your zones and your shower would be at 60 PSI.

Sorry to confuse you.  Just wanted you to know the options.

At 50 GPM flow the CSV1125 has 10 PSI friction loss.  That means it would need a pump that can do 50 GPM at 60 PSI to get 50 PSI out of the CSV125.

Yes and no. The water will flow backwards through the CSV1A no problem, but it cannot prevent the pump from cycling on taps before the CSV.  So if you use the tap for something small like filling a dog water bowl ii is OK.  You can also use that tap for irrigation as long as the amount used maxes out the flow from the pump so the pump cannot cycle off.  Otherwise it is best to out the CSV at or in the well so it is before any taps.

Sorry for your problem. Glad you figured it out.  Always glad to help even though it is rarely a Cycle Stop Valve problem.

Yeah the CSV125 or the CSVS125 need to go before the first tee.  The pipe before the CSV will see the max pressure whatever pump you get can build.  The 1/2HP, 10 GPM can only build 100 PSI.  The 3/4HP, 10 GPM can build 140 PSI.  The 1HP, 33GPM can only build 90 PSI, which is why it needs to go in a cistern or a well with a shallow water level of less than about 40'.

It is rare for the CSV to cause a lose of flow.  If they fail they usually fail in the open position, and the pump starts cycling on and off while using water.  A loss of flow is usually a clogged filter, a hole in the pipe, or a bad pump.  It is easy to take the CSV1A apart if you want to see if there is something stuck in it restricting flow.

All pumps are subpar these days.  That pump should be large enough, as it will run 3 showers at the same time.  If you are complaining about the pressure we can fix that.  A 10 GPM, 3/4HP would be a good upgrade for more pressure.  But you can get a 1HP, 33GPM, 230V Hallmark for about 160 bucks on Ebay.  Even though that is way larger pump than you need, the CSV will make it work like a small pump when needed while still delivering strong constant pressure to the house.  If your pressure tank and switch are still good all you need is the CSV1A valve.  But the CSV1A valve comes in the PK1A kit which also has a new tank and everything you need to replace what you have now.

The only difference between the CSV125 and the CSVS125 is the SS body.  The internals are the exact same plastic parts.  You should never need to repair either.  But you can repair the CSVS, it will just cost more than a new CSV125.  Just call for a replacement, and send in the old valve back for an inspection.  That is not a normal problem we will want to figure it out.  Most times we find nothing wrong with the old valve, and the replacement valve does exactly the same thing.  That is usually how we figure out where the real problem is.

Must be something lodged in the CSV125. Otherwise it could not do that. We will send you a new CSV125 at no charge. Just call during regular hours.

If the CSV is in the well there is no way to put a  pressure gauge  before the CSV.  The CSV is not the problem. Go ahead with replacing it with a nipple. Nothing will change.

The CSV125 is actually rated for up to 50 GPM, so 12 GPM is no problem.  You say the backpressure goes from 120 to 50 depending on how the water is being used.  What are you using when it gets down to 50 PSI?   120 to 50 backpressure sounds like the CSV is working.  The back pressure should also not go to zero after the pump shuts off.  Makes me think there is a check valve after the back pressure gauge somewhere, as the CSV cannot prevent reverse flow.  The pressure before the CSV should be the same as after the CSV when the pump is not running.  Still think something else, like a check valve, is blocking flow.

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.
