What is a macerator?

To macerate means "to soften in water" however it is now commonly accepted in the plumbing industry as well as in the marine world that macerators also mean "to shred or to break in pieces". In our case, the macerator shreds waste and paper and pump these wastes away as thin slurry. The manner in which the waste is reduced is very simple, a serrated type impeller or a cutter blade shreds and pumps at the same time.

 

Is venting necessary?

All plumbing codes in North America require that p-traps, sump pumps and sewage pits are vented. This requirement includes macerators as well. Our macerators have a tapping on the lid, that needs to be opened up and then the case can be vented to a vent stack. A single vent leading from the case can pickup the vent from the hand basin, shower or bath. The vent pipe size is 1-1/2 inch pipe.

 

Can I connect other fixtures to the macerator?

Yes, the Saniplus and WaterGenie have a connection collar on the lid of the unit. The vent connection collar is 1 1/2-inch in diameter. The inlet drain connection collar is 1 3/4-inch from the floor to the center of the opening and is 1 3/4-inch from the rear of the unit to the center of the opening.

 

Does the shower or bathtub need to be raised?

Yes a platform of 2 x 6 inches or even 2 x 8 inches (if you have the head room) is necessary. This allows the installation of a P-trap underneath the shower or bathtub.

 

Is the product certified?

Yes the macerator and the toilet are certified. Macerator to the CSA B45.9 in Canada. Macerator to the ASME A112.3.4 in the USA. The toilet to the CSA B45.2 in Canada. The toilet to ASME A112.12 and 19 in the USA.

 

Is maintenance required?

No maintenance is required.

 

Do I need to winterize the product?

Yes, where freezing is likely to occur, the macerator and the toilet must be winterized. This can simply be achieved by pouring plumbers (or recreation vehicle) anti-freeze in an empty toilet tank. Flush the toilet and the anti-freeze solution will fill the toilet bowl trap, the macerator and the discharge pipe.

 

Does the horizontal discharge pipe need to be laid to gravity flow drainage?

All horizontal piping must have a 2% slope (1/4-inch to 1 foot). Do not raise the horizontal pipe again once the highest point has been reached at the macerator.

 

How high and far can the waste be pumped?

12 feet vertical maximum. 150 feet horizontal maximum. When combined, a lesser combination of these two values. Raise the discharge pipe as high as necessary and from that point on, the discharge pipe must be laid to gravity.

 

Where should I connect the discharge into?

As close as possible to the soil stack. But preferably into the soil stack.
