Hello all
First time posting here.[:I]

My old 42 gallons galvanized water tank has seen better days.

I would like to buy a new tank; I plan to install it myself.

My options are flotec at Home depot or wellsaver at Lowes

I was looking at the 36-gallon pressure tank but I got a little confused with the maximum drawdown of 13.3 gallons and pumps up to 12 GPM?

All I know about my well pump is that is at least 15 years old, buried in the back yard and is 1/2 HP/115V.

Can someone here educate me on this well water pump business?

Thanks
