Hi All.
We’ve had a 85 gallon pressure tank given to us, which I’ll add to our existing well system with a 25 gallon pressure tank.
I’m thinking about a simple 1″ brass manifold in front of the tanks with ball valves before each tank so that if one fails it can be isolated, removed and replaced. Hence the well pump will be on one side of the manifold and the house on the other side. The pressure switch will be somewhere in the middle.
Is there anything else I should consider?
Thanks,
Scott.

A union between the tanks and the valves.
Why do you need a second pressure tank? Seems redundant!
.........Iron Helix
Increased capacity will lengthen the time in between pump cycles, usually overkill to buy one but I think he said he got it for free.
And increases the run time duration with the "on" cycle and gives a longer wait for the pressure to be boosted toward the cut-off pressure during water use.....right?

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
But you could probably tighten the differential.
>>>but I think he said he got it for free.Exactly. The current tank has 14 gallons of drawdown; this will triple that. I really hope it lengthens the pump life because I have no desire to pull a 220' column of 1 1/4" water pipe through a hole in the roof, though I'm sure it will happen some day....Thanks for the responses... this sounds pretty simple.Scott.Always remember those first immortal words that Adam said to Eve, “You’d better stand back, I don’t know how big this thing’s going to get.”
Make sure the pressure switch is between the pump and any valve. I added a second tank for a customer because he also used the well for irrigating a few acres. Had to replace our pump last year because the splines between the motor and pump wear out due to starting. The pump guy asked if we irrigate with the well as this is a common cause of failure. The male splines on the motor are fine but they dont sell just the pump.
With no water pressure in the line or tanks, set the air pressure in the tanks so they are equal, at 2psi. under the cut in pressure of the switch.
Pump companies say longer run time, and longer off time adds to the life of a submersible pump. The longer the pump runs, the more water passes by the motor helping to keep the motor cool. More off time allows better heat dissapation.
One minute is a recommeded minimum run time.
A union as the fist fitting at the outside edge of the tank makes future repairs quick and simple.
