Treatment for Contaminated Sewage Fixtures

First of all you’re dealing with sewage, so wear your personal protection.
If you ever cut yourself do not stop the bleeding (unless excessive) force more bleeding by squeezing the area. This forces any contamination out of the wound. Once you feel it is clean disinfect the area.

When rebuilding toilets, pumps and vacuum systems, it is best to start clean so it is best sometimes to remove to a workbench with good lighting.
Follow the manufacturers instructions to remove the bulky pieces (like the bowl off the flushing mechanism) wrap in plastic bags and remove to your work area.

If possible rinse off the parts with clean water beforehand.You will need a plastic rubbish bin or a large sink.
Place parts to be cleaned in the bin (no electrical parts).

Fill with warm to hot water till water is just over the top of the last piece.
Sprinkle over the top of the water 1 tablespoon of  Noflex.
Hot water speeds up the reaction cold water slows it down.
The surface of the water should start to foam as it reacts with the waste, this will stop once the Noflex is spent or there is no more waste. This can take anywhere from 1 to 24 hours, so it is one of those jobs best to be done late in the day and left to sit overnight.

In the morning add a tablespoon to the bin after 30 minutes if there has been no reaction (more bubbles) you can start removing the pieces for disassembly. If there is a reaction add 2 more tablespoons and wait 2 hours before disassembly.

Once you have the parts on your work bench you can start taking them apart. If you run into something that is still dirty use a brush in the garbage can full of water to clean.

The Noflex is not a disinfectant so even thought the parts look clean they may still contain coating of raw sewage. I recommend after you have all the parts clean and laying on the bench take a spray bottle with regular bleach and soak all the parts and table top area, let it air dry.

Start your rebuild.
