Macerator advice for newbie

[Lucy387]

Hi there,

I’m having a new bathroom installed and the awkward shape of room means that the best option is to move the toilet and fit a macerator.

I have chosen for a corner toilet as it’s the best space-saving option, but would appreciate some words of advice and wisdom when it comes to the macerator.

There is very little space behind the corner toilet to accommodate a macerator and I am struggling to find a macerator with suitable dimensions.
Can I place the macerator long-ways against the wall and run a flexible pipe from the spigot to the macerator? It would be about 1ft/
1 1/2ft long.
Or does the macerator need to be directly attached to the toilet spigot?

Advice gratefully received! I am not a plumber, just a home-owner who is trying to learn the most basic of basics!

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?

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.

The reality is people do put the wrong stuff down a bog and expect it to work like a normal one, and often its up to the householder, their engineer, etc to
get the thing back working after its jammed ..I agree with you about the wrong stuff.

Reality and theory are different..we have a lady we put a saniflo in for under her stairs years ago, as she only uses it there has never been a problem
but ...these units are problematic in my opinion

Hi Lucy,

Do you have another lavatory in the property?

 

[Lucy387]

Hi Lucy,

Do you have another lavatory in the property?

I do, yes, a small cloakroom downstairs.

 

[Ben-gee]

That’s good.

I think you just need a fitter with more experience/ ability to think outside the box to suss this out for you.

Really, don’t go with a macerator.

Where are you located?

 

[Robert Bell]

I thought you had to have a soil piped toilet as a main if you wre to have a macerator installed by regs.

Thought it was answered Rob. A macerator toilet can not be the only toilet in the property. There must be one on mains drainage.

Thanks, I’m starting to understand that there are better options to having a macerator. I’m in South Wales.

Yes Lucy ..a gravity system properly designed and installed will always beat a macerator, people do install them because they Really have no other option ..you do, re post with a diagram and we will help you get it right...Rob Foster aka centralheatking

Finally.... a

 

[Lucy387]

Thanks everyone for your help and advice. I am really grateful. I have posted a diagram of my ideal set up for my bathroom including dimensions and some details.
I have already purchased the suite so I would really like to make this layout work if at all possible.

Is it possible for the internal soil pipe to run as diagrammed in my picture (blue line)? It would be almost a 3m pipe with 3 bends. Is this possible to do without the risk of blockages?
Also, is there a standard ratio of fall that I would need to have? How would I work out how much to raise the toilet or lower the waste outlet?

Many, many thanks!

 

[Riley]

Are you doing this install ?

 

[Ben-gee]

Is there any reason you can't run the soil pipe on the outside?
Then you wouldn't have to raise to lavatory at all?

Well, if it went on the outside then it would have to go across the front of my house and I don’t particularly want it to do that.
