Saniflow or wastepipe

[mk12874]

Hi,
I'm looking for advice on the classic saniflow Vs standard toilet issue.

We're looking at getting an understairs toilet fitted in our house. We've had 5 people round to quote for it and all but one suggested we use a saniflow to go under the kitchen cupboards and out to the soil stack. The last person quoting for digging up the concrete kitchen floor and putting a 110mm waste pipe in instead. The quotes were roughly the same cost.

I'd definitely prefer the normal toilet version, but I'm worried that this 5th person hasn't spotted something all the others have. Or maybe the others are suggesting the saniflow because it'll be easier for them to fit it?

Are there any major issues in digging up the concrete floor? Breaching damp course or something? Anything in particular to look out for?

Thanks

digging up the floor and getting a new connection to the soil pipe is a major job. Yes, you'll go through the damp proofing . Can you post some pics of inside route and outside too - somerimes it's better to go outside and undergtound .

One rule often overlooked with macerators is that you cant go down below floor level, along and then rise up at the end without effecting the life expected of the unit.

Get a Saniflo, they're the easy option and they are fine for occasional use. Mrs Mottie says ours is only to be used for number ones but when the cats away…….

You'll be sorry!

You'll be sorry!

Why do you say that?

You'll be sorry!

Had ours more than 20 years. Only blocked up once when I had a cold, was blowing my nose on Kleenex tissues that are different from toilet tissue and chucked a big wedge of them down there.

Here's a rough image of the potential route:

Just outside the wall at the bottom is a garden wall (about 60mm gap between it and the house) so running a full size pipe round the outside is probably out.

Mines run outside on my flank wall in 22mm copper. If it was on your picture, it would run from top right corner to just round the bottom right corner.

Are all your floors concrete?

How old is the house?

 

[mk12874]

Yes, concrete. It's an old Victorian house so >100 years old.

110mm pipe (laid correctly) is going to be fit and forget, and will take a lot more abuse than a Macerator will cope with.

Just be prepared for a few surprises though if you start digging up an old Victorian Floor, you never quite know what's underneath...
