Recently went downstairs to find a floor full of water near my HW Heater, softener and well pressure tank. Checked all 3 units and found multiple pinholes in the side of the pressure tank. Time for replacing. Also possibly time to increase size. Want some answers/opinions before I do it.
\*\*Current tank is a Goulds V200 (65 gallon). According to their site the drawdown for my 40/60 switch is 17.4 gallons.
\*\*Current pump is 3/4 hp Jacuzzi that produces 18 gpm according to the installation tag on its disconnect box.
Researching how to size a tank lead me to understand 18 gpm should be sized at 1.5 gallons of drawdown per 1 gpm. That's a drawdown of 27 gallons. Seems like I'm short cycling my pump with its current 17.4 drawdown.

Looking at sizing up to an 86 or 119 gallon tank. The 86 has a drawdown of 23.03 gallons and the 119 has a drawdown of 31.86 gallons according to the manufacturer specs. My pump seems to be right smack in the middle of these. Would it be fine to move all the way up to the 119 gallon almost doubling my drawdown capacity? The pump would run longer per cycle but cycle less often.
Drawbacks?
Pros and cons?
Assumptions: Not concerned about tank cost at this time. There is proper space for the 119.

Thank you.
