3M Aqua-Pure™ Opaque Replacement Sump for the AP101T

The opaque replacement sump fits  the AP101T, AP11T and AP141T whole house water filtration systems and is a genuine OEM part. Replacing the 3M Aqua-Pure 69811-31C sump on your filter system is recommended every 5-7 years. This is especially important for filter systems that are consistently exposed to sunlight or high pressure above 60 psi. The plastics break down and the potential for catastrophic failure increases over time.
