Description
18 l Lead-Free Potable Water Thermal Expansion TankThe 4. 8 gallon XT 18 Thermal Expansion Tank is utilized on potable water lines between the backflow preventer or pressure reducing valve and the water heater for protection against water thermal expansion in residential applications. As the system pressure increases, water enters the polypropylene lined water chamber of the tank, expanding a diaphragm into a pre charged air chamber to keep the system pressure below the relief valve setting.

Very nice looking
Color: Brushed Nickel
I like the metal finish on this caddy. It looks very sharp on my countertop. It holds everything I need close at hand to the sink. The only thing I wish was different is where you can put brushes with handles. They fall through the metal piece at the bottom. I wish that part of the caddy had a solid bottom piece.

Perfect For My Current Setup
Color: A-silver
LOVE this! Exactly what I wanted and needed for my outdated sink and countertop that is bad for collecting water until I can update. LOVE the mini, removable tray that catches water. Love the separate scrubber slots. Love the size and shiny stainless steel. Hope it stays shiny after I clean it.
