It’s a 4-gallon tank and can hold up to 3.2 gallons of filtered water when full which is a pretty decent amount for residential use.
The tank comes pre-pressurized between 7 to 10 psi and has a maximum working pressure of around 100 psi. Therefore, it can work pretty well with municipal feed water pressure as well as a boost pump.
The T32M is a perfect RO replacement tank for diverse use as it discharges effectively in both vertical and horizontal positions. It comes with a tank stand which you can use for either the vertical or horizontal position.
The water chamber is a high-quality, FDA-grade butyl diaphragm that has gone through special post-cure procedures to make sure that the water held in the tank remains safe, tasteless and odourless.
The inlet/outlet valve connection of this iSpring tank is also made of stainless steel. It won’t strip or break easily and it does prevent contamination by lead leaching.
The connection fits standard ¼“NPT thread ball valve which is fortunately included with the tank. The unit also has a standard air nozzle at the bottom part which you can use to adjust the air pressure inside the tank if needed.
In short, the iSpring T32M is a superb storage tank perfect for use with under-sink RO systems and has enough capacity to meet the daily clean water demand in a household.
