Hi Guys,
Looks like a great forum you have here.....maybe you can help me out. I want to replace my well pressure tank but need help sizing a new one. My current tank is original to the house, which was built in 1977. The label on the tank says;
Medalist Manufacturing Co
Posi-Pressure II, Model PP2-42
36 gal capacity
Draw Down = 11.6 (20/40), 9.5 (30/60)
16” Dia, 50” H
150 psi working pressure
I can't find any info on the web for this tank or the company that made it, but from the looks of it I don't believe it has an internal bladder or diaphragm............I think the air pressure acts directly on the liquid inside the tank, but I don't know what you call that type of pressure tank. There's a Schrader valve on the top of the tank, but that's it. The tank itself is a single piece of steel, not two half tanks like most bladder tanks. Regardless, the tank loses pressure within a few days of me setting it........so I'm going to replace it. I checked the Schrader valve and it doesn't appear to be leaking, but even if it has a very slow leak I don't know what the internal condition of the pressure tank is and want to replace it (along with the hot water heater, which is also original to the house). I'd rather replace these things now when it's convenient for me and not when one of them fails and makes a heck of a mess (usually late on a Sunday night when we have friends over).
When the house was built water demand was from 2 full bathrooms, kitchen, washing machine and 2 outside water spigots..........so I assume the tank was sized for that demand. Sometime before I bought the house an addition was put on, which added a third full bath and another outside water spigot. We're a family of 3 people with frequent guests visiting on weekends, so I want to make sure I size the pressure tank correctly. My well pump is located in the well, and I don't have the specs for it. So based on the tank label info and my current water demand..........can you tell me how to determine the correct size tank to use? If not what other info do I need?
I'm leaning toward a Flexcon Flex-Lite composite tank from what I've been reading. Does anybody think that's a bad idea? Oh, I'm a bit limited in the space available to put the tank, so I really don't want to go wider than 16" diameter............but I can cross that bridge after I figure out what capacity tank I need.
Thanks in advance.
regards,
bob
