Hi Lawrosa,

How about the ones intended for reverse osmosis?

Yes any tank made for potable water....

I agree with lawrosa - use a larger tank. Here's the one I put in: 2 gallon pressure tank. It does the trick!

Hi Lawrosa,

accumulator tank waste of money IMO unless you get a larger tank like used for a HWH... You will not like the results with the tiny ones they sell for RV that hold less then a 1/2 pint of water...

Just need a 3/4 x pex adapter, a 1/2 pex tee, and a small length of 1/2 pex hose...

IMO youll be happier with the results all for under $50 bucks...

I put a T valve on ours when we had one. Then I could empty out the last bit of water in it.

I have a valve at the tank that I close after expelling the water then I can pump the antifreeze into the water lines.
