Washine Machine Macerator

[Mr La de da]

Guys,

I have a WC with a macerator for the toilet and basin which is fine, but I need to add a washine machine. So I am thinking is it possible to get some type of pump/washing machine macerator that can be plumbed into the same waste pipe as the existing macerator? The machine will be in use a fair bit 3 times a day at least.

The pipe goes up for about 3 meters then at least 10 meter horizontally before it drops into the main pipe out. Could do with some advise on the best solution on this?

Thanks in advance.

No, it will need it's own pipe.

Thanks Mike, do you know if a combi type macerator is made, one that is connected to the toilet and has a washing machine connection into it ?

speak to saniflows they will tell you which macerator to use, ideayl there shouldnt be a horizontal run on any macerator even a slight fall from the highest point is preferableif it within a floor void you should be able to get a fall on it

How far from the macerator is the washing machine? Many macerators have an entry point for a basin waste, maybe someone with more macerator experience than me could say if that could be used? I have zero experience with them as I avoid jobs when I hear the word 'macerator'.

You can't use a macerator designed for a toilet with a washing machine or kitchen sink. It has to be something like a Sanivite. There are pumping stations available but these are much larger and completely different.

Ahh I see, well that shows my lack of macerator knowledge.
Did a quick check of some macerators MI's and found them all similar to the following pic, it looks like they can handle basin/shower wastes, but not dishwashers/washing machines.

Had a look today at the pipe run and it's longer than I had hoped, also there is a metal vent pipe in the way that will hinder drilling holes for the new pipe, it's in a commercial property so need to gain access the the unit next door which isnt a problem because it's empty just a pain that we dont have proper plumbing.

The picture above would be an ideal solution as it's easy, because the washing machine will be close to the toilet macerator, I will call saniflo and ask what they have for our situation, probably not going to be the cheapest 🙂
