A heavy-duty powder-coated steel wall-mount bracket that securely supports three Big Blue water filter housings for a 3-stage system — fits both 10″ and 20″ Big Blue housings and keeps stress off your plumbing.

What it does

The MyWaterClub Triple Big Blue Mounting Bracket carries the weight of your 3-stage Big Blue whole-house filtration system so your inlet and outlet plumbing doesn’t have to. Three Big Blue housings bolt into the bracket and the bracket bolts to the wall — giving you a rock-solid, permanent installation.

Beyond simply holding the housings up, the bracket keeps them parallel and evenly spaced so cartridge changes are quick and clean, and it prevents pipe fatigue over time by taking the load off your 1″ NPT fittings and unions. Ideal for basements, garages, utility rooms, or any mechanical area where you want the install to look clean and stay put. Fits both 10″ × 4.5″ and 20″ × 4.5″ Big Blue housings — use the same bracket regardless of housing height.

Good to know before you buy

• Mounting hardware is not included. Choose wall screws and anchors appropriate for your wall type (wood stud, drywall, masonry, etc.).
• Anchor the bracket into studs or solid backing — three water-filled Big Blue housings can weigh 40–60 lbs (more for 20″ housings). Toggle-only mounts loosen over time.
• Attach housings to the bracket using standard 5/16″ hex head screws (sold separately).
• Leave clearance below the housings equal to the cartridge length — about 12″ for 10″ housings, 22″ for 20″ housings — so you can drop the sumps for filter changes.
• Designed for indoor or protected installations. Not for outdoor exposure.
• Ensure bracket is level before tightening fully — a tilted bracket makes cartridge changes harder and stresses the plumbing.
• For 1-stage or 2-stage Big Blue systems, use the matching single or dual Big Blue bracket instead.
• Professional installation recommended if you’re cutting into your main water line.
