Falcon Stainless EXPT-2 Thermal Potable Water Expansion Tank 2.1 Gal with Butyl Bladder/Polypropylene Liner and Stainless Steel 3/4-Inch Male Thread Connection for up to 50-Gallon Water Heaters

Nicely made hardware. Follow installation instructions. At one point it suggests not installing the tank sideways because of the stress it's weight, when filled with water, would have on the copper pipes and solder joints. 8.3 lbs per gallon of water. 2.1 Gallon (if the bladder fails?) is 17.7 lbs. In a later section it shows a sideways installation with a SUPPORT for the tank. Support the tank if you must install it sideways. Vertical installation is urged. Nozzle up or nozzle down? Nozzle down/tank up above my electronics-laden Heat Pump Water Heater, looks easy enough but what if something should leak onto the electronics? No. Not above the heater in any direction for me. From other reviews I concluded nozzle down/tank up is ideal because even if the bladder eventually fails, the air trapped above will still have a cushion effect which will help keep the system pressure lower during expansion. I built a wooden framework secured to the basement ceiling joists off to the side of the HPWH. The tanks rests in it with the connecting flex tube (from the nozzle) joined to a copper T-fitting. I left enough space at the top to access the schrader valve for occasional checking and refilling with air. Our neighborhood around 55 psi.

Great product at a good price. I installed the tank took about 2 hrs. Plumbling experience is helpful. Filled the tank psi to what my water pressure was no problems. Great product and solve a problem of having excessive pressure. Disappointed that tanks are made in China but 99% of them are. Good quality and painted very good overall very happy.

The old potable water expansion tank had failed due to former owners neglecting maintenance on the house water system. The T&P valve failed, the expansion tank failed, the pressure reducing valve failed and the house was feeling full city water pressure which varied between120-140psi. This was an easy swap for the old tank and liked the materials it is made of and apparent quality construction.

So far seems to work well. Easy to replace old unit. Maker sure to set pressure to house incoming water pressure. So buy a guage that screws onto the water heater drain valve. Then pump up diaphragm pressure with bike pump to that pressure before instillation. Think the unit came set at 45psig but increased to 65psig. Used car tire plug in pump to increase pressure. After instillation the water heated relief valve stop popping once per day.

Excellent product....Easy to install....Pressured it to 55 PSI, and it was good to go. It's been installed for a few days, so a little soon to write an extensive review, but I see no reason it cannot last as long as the one I removed after about 15 - 20 years. The welds are solid all around, and all indications point to it being a quality product.

I bought two for two new water heaters I installed. Both are fine, no leaks. The houses previously did not have them and I blew out one old water heater by turning off the water main shut off and not thinking about the pressure building in the water heater as the heater cycled. Came home to water everywhere in the garage.

Very impressed with the construction of this tank. It solved my over pressure issue and actually looks pretty nice doing it, even tough I don't plan on showing it off. It's sturdy, easy to pressurize, easy to hook up, and the outside coating feels substantial. I have zero complaints. Great value.

Just in case anyone thinks that this tank is constructed of stainless steel, it is not. You will never find an all SS tank at anywhere this price. This tank is made of heavy gauge steel with a really nice, possibly epoxy, paint finish, with a connector make of stainless.

Excellent product met our needs
