Two Homes Off of One Well Pump

[mike48130]

My understanding of the CSV is it stops the pump from cycling (turning on-off-on) during specific usage situations where the usage (draw down) flow duration is longer than the normal pump cycle duration. Thus it stops the pump from turning off/on several times when water is constantly being drawn. The pump just turns on once for a long time.
Thus, while pump run time is longer, the number of cycles is less. Which is good.

(IMHO) Depending on your ballast tank size, for most usage like flushing a toilet, brushing your teeth, filling a pan of water, the short duration of your draw doesn't cause your pump to repeatedly cycle and I don't see the benefit of a CSV.
Don't get me wrong, there's long duration draw down applications where a CSV makes sense, but it does sometimes seem like its promoted here by its inventor as a solution to any post regarding well pumps. That's my impression.
I don't have a problem with Valveman, his forum name lets you know where here's coming from.

It does sometimes remind me of once being at a horse show with my wife watching our daughter ride. A nice lady next to me started talking about how nervous she was watching her daughter...we were nervous too...a pretty lady, a nice friendly conversation, then she mentioned the thing that calmed her nerves was Lavender Essential Oils. How they made her sleep well, gave her focus, relieved soreness (might of cured cancer too!)..okay...that's interesting...blah blah blah...and then she just happened to have some extra bottles for sale...."and oh by the way......what's your email so I can get you on the mailing list for the whole product line of Essential Oils." or maybe she gave us a business card with the weblink.

Then I thought to myself "Oh, that's what this "friendly conversation" is about...ok, uh-huh"
The whole encounter felt.....what's the word?

The snake oil salesmen have been around for hundreds of years.

See this is the kind of stuff I have been dealing with for 28 years now. I know the CSV sounds too good to be true. Eliminating the cycling really does solve nearly every problem associated with pump systems. I have always offered a money back guarantee, and in 28 years have never had anyone return one. Once they see how it works, even the skeptics are amazed. Several major pump manufacturers blacklisted the CSV in 1994 as a disruptive product. "The CSV makes pumps last longer and use smaller tanks. Anyone working for xxxxx pump company who mentions a CSV will be terminated immediately". We should all be angry about corporate planned obsolescence. I make something that shoots their planned obsolescence in the foot and they don't like it. Some people accused Galileo and Columbus of selling snake oil, and they were wrong too!

I would love to see what the pressure in the line is between pump and CSV when only 1 gpm is flowing and you have a pump that can deliver 20 gpms at 50psi.

As for use cases, I would very much like to put a single sprinkler or soaker hose on by itself and not have the pump cycle every few minutes. I can run 4 or 5 sprinklers in the yard and the pump stays running (which is what we do), but there are many times when it would be nice to just be able to leave a hose running a little bit to water a tree for a few hours so it soaks deep.

The CSV style sounds kind of intriguing to me, I may give one a shot when I have to work on my pump.

Hawkeye08 what I found interesting years ago was that throttling pumps down reduced the amp draw as compared to open unrestricted flow.
I have seen many 3 phase pumps that would trip the overloads when the pumps were run with no restriction.
My personal house water pump needed to be restricted or it would run with a higher amp reading then recommended,
my lift was less then the pump was rated for and it would over perform and over load itself if not restricted.

Well that depends on which pump you have and your static water level. This is the one thing we figure for every pump to make sure it is compatible with a CSV. In my case I have a 25 GPM, 2HP with a static water level of 120'. This pump has a max head of 330'. Subtract the static water level and divide by 2.31 to find out how much back pressure the pump will build. 330-100=230/2.31= 99 PSI. When the CSV puts 99 PSI on the pump and makes it think it is in a 330' deep well, it can then only produce 1 GPM for a soaker hose when needed. Mine runs 3 GPM for a drip system in the garden for many days/months at a time. In the last 28 years the CSV has saved millions of cycles and my pump is still running. Never lasted very long before installing the CSV.

As for use cases, I would very much like to put a single sprinkler or soaker hose on by itself and not have the pump cycle every few minutes. I can run 4 or 5 sprinklers in the yard and the pump stays running (which is what we do), but there are many times when it would be nice to just be able to leave a hose running a little bit to water a tree for a few hours so it soaks deep.

Kudos that you understand four or five sprinklers are necessary to keep the pump from cycling to death. Most people just run one sprinkler and don't understand why their pumps don't last very long. But yes a CSV lets you run water anyway you want without having to worry about cycling.

Wasnt directed at you. That's why I quoted the post about the lady selling oils. See it was kind of like one of those pun type things. She was trying to sell him oils.......... snake oil salesman.......... get it now?

LOL! Now I get it. Sorry, I have been called that so many times in the last 28 years I instantly think it is directed at me. Looking at our reviews you can see that nobody who ever tried a CSV would say that. But I hear it all the time from people who "think" they know how pumps work.

I have run my place directly off our well/bore pump for years but it is hard on the bore pump stopping and starting all the time.
I finally fitted a 5000 litre water tank fitted with a Hansen Leveller valve. The bore fills the tank once every 5-6 days when the level in the tank drops down low. If it rains the tank refills and the bore doesn't need to be used.
I have a household pressure pump now from tank to house.
If you have a tank on each house you can fill both from the well and use household pressure pumps for your supply. Hansen valve is ideal in this situation. (one in each tank)
You can set the leveller valve to whatever level you want in your tanks.
If I ever have a failure I turn a tap and it switches back direct to bore again.

Cycling on and off is bad for any pump. You just swapped the cycling problem from you bore pump to the booster pump. However, doing it yourself I am sure you would be able to work on the booster pump much easier than the bore pump, so not too bad an idea. However, if you stop the bore pump from cycling on/off, it will last a long time and the storage tank and booster pumps would not be necessary. Water coming straight from the well is usually clean and pure. When this water is put in a vented atmospheric storage tank, it is now exposed to the air and heat. Care must be taken and usually chlorine added to the storage tank regularly to prevent stuff from growing in the storage tank. Plus, when supplying the houses straight from the bore pump you don't have the extra expense and maintenance of the extra booster pumps and the extra electricity they use.

You can use a CSV on the bore pump well and/or the booster pump, then cycling is greatly reduced and any pump will last longer
