Macerator advice for newbie

[Lucy387]

There is space behind the boxing in and the pipe would fit behind the bath.
The plumber said that the only issue was creating enough fall so he asked me to find a toilet with a high outlet. When I couldn’t find one, he said I’d need to have a macerator.
So in your opinion, can I get away with having a normal toilet and running the soil pipe internally along the wall and boxing it in? It would run for about 2 1/2 metres, including around two corners, from the toilet to the soil stack. Are you saying that the fall isn’t a problem?

Thanks again for your advice!

I just said I couldn’t see the fall being a problem, obviously wouldn’t know without being able to see it for myself. If you were to contact a supplier or look up on google, a high outlet toilet, you would probably find one. In my opinion, I would always try gravity systems first (less cost and complications generally).

What's the other side of the internal wall on the right that creates a dog leg in the bathroom?

Personally I'd look at a 900 square shower in the alcove - no bath. Build the end wall out to 900mm which would then leave room for a soil pipe from the wc mounted where the bath end is. The sink could go along the LH wall. By using a Novellini bifold door (they fold ALL the way back) access to the shower is full and free.

It's the staircase, sadly no scope to knock through.

If budget is tight then be sure to factor in the cost of calling a plumber out whenever someone even gives the saniflo a dirty look and it gets blocked... (many plumbers won't touch them when they're blocked - which is understandable) 😱

Back to my first point, you just need a decent designer or experienced bathroom fitter to help you. It really is possible to sort this without a macerator.
Whereabouts are you?

Now you're scaremongering the op! Depending on which make and model, possibly the hardness of local water, the installation and not asking it to deal with items it wasn't designed for it could last 15yrs without trouble.

So is there a way of having the layout I want and having the toilet plumbed in without a macerator?

The current problem is that the new loo and the existing outlet are the same height so the plumber said it wouldn’t create any fall. He said to find a toilet with a high outlet (at least 220mm), but I couldn’t find one despite asking the local suppliers, so then he said a macerator would be my best option.
But what if a new hole is made into the soil stack, say 2 or 3 inches lower than it currently is, and running an internal soil pipe to it? That would give me a fall of 2 or 3 inches across 2.5m. Would that be possible?

Put pan on plinth? Better than using a macerator.

It would be possible, but obviously need to repair old hole then. Your plumber has probably already done this, but have you measured the floor to centre of existing soil pipe and toilet and your new one?

Yes, both are 180mm.

It really is simple to sort.
1) raise the pan outlet height.
Or
2) lower the soil connection height.

1) is achieved by building a plinth.
In your case I would raise the whole floor from half way along the corridor part. One step should suffice , the wc and basin would be on this raised floor - it would also have the effect on making it easier to get into the bath.

2) yes this can be done, obviously we can’t see how in your case but trust me it can. That’s why I keep saying you need a decent experienced set of eyes on the job.

I have just lowered the branch on a soil stack by 1 1/2 “ to give s proper fall on a lavatory. The lady has lived there for 35 years, had this lavatory changed three times and it’s never flushed properly. She can’t believe how it is now , and all for the sake of a days labour.

Hi @rpm sorry if it came across as just scaremongering ,was meant to be advisory. Op stated they were could not afford professional advise which may help them avoid a sani. My point was that this is possibly a false economy. As for sani blocking easily, you are correct they only usually block when badly installed or abused. I find it often takes several "incidents" before the message hits home and people stop putting tampons, qtips, wet wipes etc down the loo and this is a cost to be factored in. Anyway, "onwards and upwards" as they say (saniflo related humour)😀

Most plumbing components go wrong at some point. Electro mechanical devices usually the
worst. Gravity is free and rarely goes wrong. I would re design your bathroom along these principles...Complicated is easy...simple is hard. Especially when your macerator jams up when the blades go blunt or the lecky goes off. These units are meant for supplementary bogs not the main one..install at your peril. Also purchase a good pair of gauntlets and nose pegs to clear the thing out when it does go LALA. Rob Foster aka centralheatking

Blunt blades Haha. Think about it, what inside a domestic macerator could cause Stainless steel to blunt?

Even stainless steel knives used in kitchens need to be re faced
some sanitary products can be quite wearing and some things have plastic in them. let alone the things that go into bogs that should not. I agree in an ideal world these products are ok but
...our experience of fixing them in rentals is not a happy experience. Rob Foster aka centralheatking

 

[Ben-gee]

Rpm is it the case that a domestic property HAS to have at least one toilet that is not a macerator?
I seem to remember reading this somewhere, if it isn’t a rule it certainly should be!

 

[rpm]

You are correct.

None of which you talk of should be flushed away macerator or not.
