Common Questions on Single Housing Mounting Brackets
Q: What does the MB-25 mounting bracket do?
A: It secures a single filter housing to a stable surface so the housing stays aligned and easier to service.
Q: Will this bracket fit my filter housing?
A: It fits housings designed for bracket mounting. Match the hole pattern and mounting points on your housing head before ordering.
Q: Do I need a bracket for a whole house filter housing?
A: It is strongly recommended. Whole house housings can be heavy when full of water, and a bracket helps reduce strain on fittings.
Q: Can I mount the housing without a bracket?
A: Some installs do, but it can increase stress on plumbing connections and make cartridge changes harder. A bracket is the more secure option.
Q: How much clearance do I need under the housing?
A: Enough room to remove the sump and pull the cartridge straight down during service.
Q: Does a mounting bracket change filtration performance?
A: No. It improves stability and serviceability, not water quality.
Q: What surface should I mount it to?
A: A stud, plywood backer board, or properly rated anchors for your wall material to support the full housing weight.
Secure your filter housing with the MB-25 bracket for a cleaner install, easier filter changes, and less strain on plumbing fittings.
