Recommended Interior Plumbing Strategy
As an option where feasible, it is advantageous for the plumbing “stack” to be placed interior to the block walls for the following reasons:
- The plumber does not need to hammer drill the stem wall to accommodate any of the plumbing;
- The mason does not need to cut block around the plumbing contained within the wall;
- The kitchen or vanity cabinet should be made with a 3″ to 6″ false back for simple installation which allows the plumber to easily and professionally trim out the water lines and P trap inside the cabinet.
- The plumbing is within the interior of the building which greatly reduces the possibility of any of the pipes freezing.
Recommended Hose Bibb Option
The Aquor hose bibb option is the cleanest application and can be securely fastened to the block.
The photo above shows the “rough” just prior to the plumber tying the Aquor to the hose bibb line.
Please scan the QR code at right for more information. Omni Block is not a distributor and does not have any installation information nor where to buy Aquor.
The photo below shows the appropriate size hole (per Aquor) bored into the block. The photo to right is a typical masonry hole bit and the bottom photo is hyperlinked to a video showing the short time it takes to bore a hole in masonry with the right tools.
Masons address all plumbing embeds the same as they would if they were installing it into standard CMU.
1 It is the plumber’s responsibility to completely protect the copper pipe within the block wall to prevent destructive corrosion to the pipe from occurring.
2 The stretcher block middle face shell was cut out to increase the opening which allows the block to slide over the 90° hose bibb. Alternatively, an Omni Block corner block could have been used.
3 It is highly recommended to place the vertical hose bibb piping in the slab where an interior partition wall is called for. This allows for the pipe to be secured to the interior partition wall.
4 The detail shows where to ideally install a sleeve where an interior partition wall is called for. This technique can be used for gas lines, freon lines, main water, virtually anything that needs to enter the building from the exterior. All then can be run vertically to the overhead space within the interior partition wall.
5 Communicating the location of the sleeves is first marked on the slab.
6 The detail shows ideally where a sleeve should occur vertically in the block wall. Notching the bottom or the top of a block makes for the cleanest installation.
7 Up to 4” vertical waste vents are accommodated by using the corner block units.
8 The detail shows that waste vents require that a mason alternatively places the Omni Block corner units over the vent.
9 The schematic provides the dimensioning within the block wall for the proper placement of typical under the sink piping.
