I picked up a 2 gallon pressure tank to use as expantion tank for my 40 gallon HWH. I then found a unit labled as an expantion tank near the HWH in the same store. They are the same make and look the same other than paint and stickers. The other difference is the expantion tank came with a saddle valve to hook it up to a pipe. It was only $2 more so I figure that is the added cost of the junky valve that comes with it. Are they the same? I am thinking I am fine with the pressure tank I bought.
My piping is copper/pex mix. The tank is steel. I have a dialectric fitting sitting here that fits the tank. Should I use it? Also I was considering instalint the unit with a pex line up to it to help take up any movement. Is this good or over kill?
