Guidance on installing a CSV to existing system.

[mark3885]

You probably have a 7 GPM series pump, which will do 9-10 GPM from that depth. You can use the hydrant before the CSV as long as you are using 10 GPM. But the CSV installed at the tank will not be able to control that hydrant, so if you use any less than 10 GPM the pump will cycle on and off repeatedly. We make the CSV125 and the CSVS125 to put in the well, so the hydrant would be controlled as well if you like.

Not concerned about the CSV controlling the hydrant so not a problem, I guess.

Now our replacement is complete.
On Thursday we had the well pump replaced with a Gould and the check valve is holding solid. The CSV is operating at about 43 psi and we have no leaks. Found out the level of our 200 foot well is at 113 feet .... so we have a much smaller reserve ( 130 gallons ) than we thought we had. The water level used to be at 30 feet but that was 40 years ago.
We let the system rest for a full day to get the mud and other crap to settle in the well and now we will live with "silty" water for awhile. Just have to remember to wet vac the dirt, rusty crap & silt out of the toilet tank in a few days.
