Common Sears reverse osmosis system replacement parts
- Water inlet filter. The water inlet filter traps large particles from entering the water treatment equipment to prevent damage and clogs.
- Inlet water seal. The inlet water seal keeps water from leaking through the water inlet connection on the water treatment equipment.
- Tank. The tank holds the water during the treatment process in the water treatment equipment.
- Water inlet cut-off valve. The water inlet cut-off valve shuts off the water supply going to the water treatment equipment.
Pressure testing water connections for your Sears reverse osmosis system
