Toilet Shredder
May 7, 2010 7:23 PM   Subscribe

Toilet poop shredders - my friend is convinced they exist but I have never heard of them. Is there really such a thing?

A friend recently mentioned toilet shredders that chop waste to make it pass through the pipes easily. Does such a thing really exist inside the pipe or the toilet? Google search of "toilet shredder" failed. Has anyone heard of such a thing before? If they do exist, where can I find them?

They're called macerating toilets.
"instead of draining the flushed water down into the floor, the system transports it through a pump contained in a small box, typically located behind the toilet and against the wall. Much like a garbage disposal, the system uses a spinning “macerating” blade that liquefies the solid waste. The liquid waste is then forced through the discharge pipes by the pressure of the pump."

Yes. Try macerator or ejector pump.

Yes. Very popular in basement bathrooms.

If you've seen a toilet in a basement / cellar with a sign on asking you not to flush sanitary products, that's probably got the shredding system you're talking about. They are easily jammed by anything unexpected.

I just saw one of these for the first time in my life yesterday! Well, it wasn't as exciting as the exclamation point indicates. But they do indeed exist.

Yeah, if you've ever used a toilet that moos loudly after flushing, then you've used a macerator. They're the domesticated version of a Muffin Monster.

These are not uncommon in Paris apartments. They allow a toilet to be installed where a sewer pipe wide enough for solids can't be installed; you just a narrow pipe carrying liquids. They're called "sanibroyeur", "broyeur" connotes grinding or crushing, like a mill. Personally I think of them as a "moulin à merde", but I just made that up.

I'm not sure where you'd find one in North America. If you're thinking of installing one, know that they're noisy and require electricity. They also are a complete mess if they get clogged by, say, a tampon.

They are also very common on boats.
