20 Inch Big Blue Housing with Bracket
One housing, bracket and spanner. The building block.
A single 20 by 4.5 inch Big Blue housing with 1 inch ports, double O-ring seal and a pressure-release button, on a powder-coated steel wall bracket, with the spanner. Build a single-stage sediment filter for a tank or borehole line, add a fourth stage to an AquaGuard, or hold a siliphos shell for scale. Takes any 20 inch Big Blue cartridge.
What to build with it
A pre-filter. A 20 or 50 micron sediment cartridge ahead of a pump, a UV or an AquaGuard on dirty water, so the fine cartridges last.
A scale stage. The refillable shell with siliphos on the geyser feed.
A fourth stage. A GAC cartridge after an AquaGuard where the water smells.
Fitting
Two bolts through the bracket into the wall. Inlet on the left, outlet on the right, marked on the cap. Fit an isolation valve ahead of it and leave 15 cm below the bowl to drop it. Cartridge not included: choose it for the job.
