County Water Pressure Too High

It is not that easy. You can't "soft start or soft stop" a pump slow enough to prevent water hammer on pump start and stop. Even if the pressure is up, starting a pump of any size is trying to shove even more water into the system, and the pressure will spike.

Eliminating the pumps cycling on and off is the best way to get rid of water hammer. Starting and stopping pumps from a very low flow rate is then next best thing you can do. Starting a 50 GPM pump at 50 GPM or a 300 GPM pump at 300 GPM will cause water hammer. But if you start these pumps at 5 GPM, then open a valve to full flow, they will not cause water hammer. Same thing on pump shut down. Reduce the flow from 300 or 50 GPM to 5 GPM before shutting off the pump and there won't be any water hammer.

Or just run the pipe to to top of the tank. Pump near or far has nothing to do with it. A distant pump feeds water to the tank locations so adding a standpipe to the top is no big deal.

Sure, tell me how it works out when when you tell the water utility to totally rework their piping. Besides with a standpipe how to you bypass the tank if it needs to be out of service? Typical installation is the tank is on a T the infeed and outfeed pipe are the same - Close one valve and tank is isolated.

Water pressure that high can cause all kinds of issues. Fix it soon.

MIght take a couple of valves but it is a trivial problem.

I hiad forgotten about our local system. Spring about 5 miles away feeding into the town system in the valley bottom, Tank on top obviously being fed from the town network. Probably by far the most common system.

Mine was 120 and all it took was a call to my rural water provider and they installed a new regulator and problem solved.

Apparently written by CSV salesman. Total bs that VFD wild cause high pressure issues.

Actually it is very common. What do you think happens when a pressure transducer malfunctions? And that is just one of several ways VFD's can cause pressure spikes.

Barbara Hesselgrave and Water Efficiency Magazine are both well respected in the industry. I don't advertise with them or anything. They would have no reason to spread bs for me. But if you are going to hate on me anyway for something written by someone else, here are a couple more.

So you are Cary Austin, the inventor and owner of Cycle Stop Valves (CSV) headquartered in Lubbock, TX?

I have only said that a couple dozen times or so. I don't know why the name "Valveman" doesn't clue you in. I am not hiding anything. I would post a logo and a web page, but I don't want to be considered advertising. Who better to explain CSV's and VFD's than someone who really knows what they are talking about?

Maybe I will change my screen name.
