Macerator for bath tub

seannash

Hi,
So I'm looking install a macerator that can take a bath tub, sink and toilet from a bathroom in the attic

From what I can see there isn't one that will do all 3 so I'm wondering if the below will work
Option 1: Hook up a macerator that is designed to take a shower, sink and toilet and hope for the best. (Will it be able to handle it)



Option 2: Hook up the same macerator as option 1 but fit a slow draining plug to mimic the flow rate of a shower draining. To be honest I don't know if these exist or not.


Option 3: install a dedicated macerator for the bath tub and sink and another one for the toilet


Option 1 or 2 would be my preference unless someone can advise me of a relaible macerator that will do it all. I'm currently looking at Grundfos ones.


Any advise or alternatives are appreciated

Why do you need the bath/sink in the project?
what's the problem you are trying to solve?

Bathroom is in the attic on the opposite side of the house to the existing waste lines. I need a macerator to pump to the waste pipes for all services.
Don't want to / cant stick a pipe on the outside of the house.

I have always used Saniflo and used the commercial products so no drama.
Will noise at night be an issue?

I wouldn't think so. It will be buried behind a plasterboard wall (Accessible)
Do they run when not in use?

I have been working in the noise field since 1975...
I can tell you at 3 am, after a bad pint or/and a Chinese, and you are adoring the great white god, you will hear it:)
The PB will only act like a bass drum, so you need to think about sound at night

To be fair its not the main bathroom. Its more a guest bedroom with an ensuite in the attic.
We want a bath for occasional use so it wont be running everyday as youd have to pass the main bathroom to get to the attic.
