Aquainwent can help with compatible cartridge selection and replacement planning.
No. In bypass mode the water line remains available, but the water is not passing through the installed filter cartridge.
Cartridge choice depends on the water issue, flow, housing size and treatment objective. Aquainwent can recommend compatible sediment, carbon or specialty media.
The current product information lists up to 100 psi for the 10-inch housing and up to 90 psi for the 20-inch housing.
The listed operating temperature is 40–100°F / 4.4–37.8°C, so it is intended for cold-water applications.
Provide enough space below and around the housing to remove the sump and installed cartridge safely. Exact clearance should be checked for the selected size and mounting arrangement.
