Accumulator Tank

Well here is my latest experiment. It is a hot water tank expansion tank. Basically an accumulator tank. It holds 2 gallons instead of 1 ltr. I pressurized it to 50 lbs and installed it just like the accumulator. I ran about 100 gallons of water through it with different tips from 40's to 4's with great recycle times. The only downfall that I can see is that it is metal instead of plastic. I figure that a good rinse after every use should get me a year. If so I would be happy. $39.00 at Lowes.

Al, not sure what the bladder is made of. That looks like some sort of residential tank. I wonder if the ones you get from Flojet are any more chemical resistant than a standard model. I'd be curious how long it holds up.
The good news is if its a metal tank, you know when the bladder is shot by tapping the tank. If it rings, it's good. If it's a thud then you know the tank is filled with water and it's no good.

Thanks for the tip. The bladder is made of Butyl which is the same as the Flojet. With the tests I did yesterday, it looks like I can use just about any tip I need without the pump cycling too much. We'll see what happens in the real world after I use it for a while.

Now I'm on the hunt for a vender that sells the bladders for the flojets in case these tanks don't work. I took mine apart and it's a snap to change out the bladders if they go bad. Just can't find anyone that sells just the bladders.
 
usually, by the time the bladder goes bad, the tank has a rust problem.
..if it comes apart easy..
coat it with a film of axle grease to make it more rust-proof,
..and to keep the bladder from drying out.
