Saniflo and Shower waste
Discussion
Hi,
Hope someone can help.
We have bought a house that has an upstairs bathroom with a saniflo toilet.
The waste goes through a narrow bore pipe horizontally about 4 metres where it then goes down through the floorand it must joint the downstairs bathroom waste, although this must be behind the wall downstairs as I can't locate it.
Where the pipe leaves the toilet, it runs for about 40cm where it is T'd into the shower waste. There is a one way valve at the T so the pressure presumably doesn't go to the shower.
When we moved in that one way valve had failed, so toilet waste was being pushed into the shower. Yuk. I replaced the valve like for like (
McAlpine MACVALVE-2 1 1/2” Self-Closing Waste Valve White 40mm fanny trap) but I'm left wondering if that's only going to fail again as maybe it's not the right product (Doesn't seem heavy duty).
Is there a better one way valve, or is it bad form to share this waste pipe anyway.
Shower does seem to drain OK, so there is enough drop I suppose.
Thanks for reading.

You have my commiserations. Can't stand the things.I think your problem is that the shower should not be connected to the Saniflo output, rather the shower should either be a seperate pipe, or connected to an input on the Saniflow.
See the diagram here https://www.saniflosystems.co.uk/wp-content/upload...
As you've just moved in, I'll repeat the one bit of advice that everyone in the house must heed - nothing but 1,2, and toilet tissue. Nothing else. Not a single makeup pad, not one cotton bud. No "flushable" wipes. Nothing else. Nothing.
Good advice from Shtu above. I had 2 pumping up from my basement with lodgers in. Total nightmare. If your capacitor goes, which it will, you can replace it or just get one of the cheaper units non Saniflo, the internals are just the same. I usually got mine off ebay, went through quite a few.
The shower waste will have an adaptor into the Saniflo but the fall will probably be an issue.

Yeah, it's plumbed in wrong. The saniflo normally has several inputs. Mine has 3, small = shower, small = sink, big = toilet, then one small output at the top.
I've owned my place for around 8 years and I'm on my 3rd unit. 1st was always noisy and eventually packed up. 2nd was a like for like and died 2 weeks out of waranty (2 years - extendable to 5 but saniflo refused to acknowledge I'd extended (online) for free). 3rd went in recently.
Saniflo - after me issuing offical warnings to go to court, paid up for 2/3rd the cost of the latest one
The Saniflo Up is around £500. 5 year warranty. If I have to do it again, I'll buy a £150 equivalent and treat them as a consumable.

Luckily it's … only be for occasional guests.
I would say it’s unfortunate that it’s only used by occasional guests.The problem is you stand at least some chance of drumming into your family that NOTHING goes down the loo apart from pee, poo and moderate amounts of toilet paper. But you can’t control your guests, who don’t know it’s a Saniflo and don’t understand the problem.
You could put up a sign above the loo, but it needs to be so strongly worded that guests will think you’re an arse. It really is crucial that not a single pad or wipe (“flushable” or otherwise) goes down.

I recently got rid of a saniflo, digging up a lot of concrete floor in my case!Hope someone can help.

Thanks everyone.
Ok next summers project is to at least get the shower and sink waste into a different pipe. And explore options of putting a normal toilet in there.
I think I'll just make the toilet out of action for noe. When I say guests it's just friends staying. They can use the downstairs toilet. (House is a bungalow with a small loft conversion so everything else is downstairs).
Thanks

FYI - Saniflo base models only come with one input - you have to buy up the rage for multi input - Mine is an "UP".
They ARE very useful, but they do have a shelf life. My main motor died. Engineer said he'd never seen that happen before, but, it happened! Apparently my shower and sink use really shortens their life as it's constantly going on and off when showering etc. I have zero choice. Ground floor in listed building with nowhere to do "down" any further.
