I have a Leader 110 pump jet pump, a 120 gallon galvanized tank and a CSV 12540-1

Firstly I would like to use the 120 gallon tank because it's still in good condition and because we have regular power outages so the 30 gallon drawdown would be nice; but I don't know if it will cause issues with the Cycle Stop Valve.

Secondly, if I use the 120 gallon tank does it make sense to use the CSV12540-1?

Finally, If I do use the galvanized tank & the CSV how should I set things up? Be mindful that there is no pressure gauge on the pump.

The CSV12540-1 will work fine with a large tank as long as you set the pressure switch about 25/45. That way it won't take too long to refill the large tank, as it will fill quickly to 40 PSI, then it will finish filling at 1 GPM from 40 to 45 PSI. The problem will be in how to maintain the proper air charge in a galvanized tank. You will need to regularly air up the tank with a compressor or have something that inject air as the pump is running. A bladder tank would be better in that the air charge cannot get out.

A couple of 5 gallon jugs in a closet is the best way to have water when the power goes off. It will just be luck of the draw if the tank has any water in it when the power goes off. If the power goes off when the pressure is at 45, then you will have 30 gallons from the tank to use. But if the power goes off when there is only 26 PSI in the tank as is normally the case with Murphy's law, you will only have a gallon or so in the tank to use.

With an electronic pressure switch, you could set it to 35-45 PSI. Then you would always have some reserve water.

With this configuration how do I run my air line? On the old setup the line ran from the AVC to the pressure switch. Do I now attach an air filler where the AVC was and run the air line from the pressure switch to a somewhere in the piping near the tank entrance?

 

[Valveman]

There really is nothing to change on the AVC. It is just that when using a CSV, the pump won't cycle as much. And since the AVC only adds air when the pump cycles, it will add less air than normal. Just need to keep an eye on the air/water ratio in the tank.

I guess this is one of those "one of these things don't belong here" situations. I'l bite the bullet & buy the smaller tank. A 120 gallon tank here is over $900.00, maybe I can get a sale.
