Macerator behind partition wall

[MarkSmith]

Hello,

Fitting a back-to-wall toilet in loft conversion, with use of a macerator. Macerator to go behind a partition wall. I have bought a Stuart Turner WC3 and upon unpacking read in the manual that it "must be located immediately behind the WC pan and must not be mounted behind a partition wall".

Does anyone know what the problem with doing this is, please? No reason for this is given in the manual.

Other macerators can be fitted in this way, although the WC4C (which can be mounted behind a wall) will not fit in the space -- I'd have to change to a Saniflo or other brand.

Just to save people the time writing and others having to read, yes, I must be completely mad having a macerator, what a wally, ha ha ha, this hilarious thing happened to someone someone I know knew, poo everywhere etc. Thanks. That should leave more room for the helpful responses

My guess is for access for maintenance or blockages.

But they will apply to any machine sooner or later.
Believe it is the design where on one model the cutting blades are nearer the pan inlet connection.

Thanks. Could you elaborate a bit on that please? What effect does that have if I add a 10cm extension?

For goodness sakes, whatever you do, do not deviate in any way from the installation instructions. ST make good products but in my experience will do everything they can to pick fault with the installation if you call them out under warranty. If they do manage to find an issue, they will immediately invalidate your warranty and refuse to fix your broken appliance

Well, some people still think they suck waste matter in where they rely on gravity and a good strong flush of water to pick up and carry the waste to the cutting area which with ST and some others is down low near the floor of the tank. Add in the facts that a lot of flush valves nowadays are pretty weak and a few pan designs just don`t help either I think ST are covering their ar$e as (I believe) they are the only manufacture with this rule.

That`s not ST, the company they use is Pump Assist.

Outsourcing your after sales service - great for the customers

Update on this, in case anyone should have the same question in the future.

I couldn't easily find an alternative device which was going to fit the space and do what I needed, and I couldn't convince myself that the restriction was more than butt-covering by the manufacturer, so I fitted the ST WC-3 with a short extension, and so far, so good. I am aware that it won't be covered under warranty, but it won't be for the majority of its life anyway. It seems to work so far (and is really not all that loud). The plan is for this toilet to get minimal use (and very minimal solid waste) so fingers crossed. I'll try to remember to update in a year or two, or earlier if we have any problems.

Choice of toilet paper used is important

Yes, any particular ones to use or avoid? I will check that anything we use will disintegrate easily in water before using it.

Take one square of paper, put it in tall glass of water and stir with a blunt knife, suitable paper will fall apart.
Avoid recycled or air blown types
