The Dreaded Saniflo

Stingray13 · 23 Feb 2018

My wife wants to install a downstairs WC and having looked at the locations and pipework accommodations without gunning out 6" of my ground floor (Concrete floor), I don't think it can be done. and this opens all sorts of issues about cost and DPM etc.

I've worked on these contraptions and really don't like them but she has a point we could benefit from a downstairs WC but to get this to actually work we would need to ideally rise about 3m up and approximately 10m through the house to get to the existing soil stack in the bathroom, I see a Vertical and Horizontal number but no conversion factor for when using both having never installed on I am not sure if this will work

Does anyone have any advice other than don't get one, I know there rubbish

Thank You

Only other advise is...bit like a yacht toilet....if you block it you unblock it....so you could potentially have 10metres of human waste to remove from a pipe?... Rather you than me

DP you disappoint me, thought you were better than this. "10m of human waste to remove from pipe".

That distance will be fine, although it is vital the upward lift is done first, then a gradual fall across the horizontal run is preferable if possible. If absolutely no way you can run a conventional drain, then its a option, just remember, other than tissue, not to put anything through it that hasn't been through you first.

Run it in 32mm solvent weld with a minimum fall of 10mm per metre and put a big sign up NO WET WIPES AND THAT INCLUDES THE ONE`S CLAIMING TO BE FLUSHABLE.

I wish people could see the havoc wipes cause in the sewer network, blocking pipes, jamming pumps, and that's before they even get to the treatment works! Invariably the screens used to remove debris at the inlet to the site fail due to these wretched things. A Macerator in domestic premises has absolutely no chance. Its high time the manufacturers were made to contribute towards the costs of dealing with the things.

It's a bit far for me, but maybe some of you should organise a forum meetup!

Fit a drain tap ( or similar ) at the base of the vertical to allow you to drain the vertical into a bucket when you need to take the Saniflow apart for any reason.

I tell all my customers to keep using wet wipes and I'll be back to jet their drains out again!

I agree with that and also add to that list the dry tissues that you blow your nose on. They are definitely not suitable to go in a macerator. I lazily checked a wodge of them down mine, blocked the damn thing and burnt out the capacitor. Okay, with some good advice on here from just pumps I fixed it for about a fiver but what a palaver- I have the sanislim and it is boxed in - major aggro to get it out, dismantle, clean, fix and refit. https://www.diynot.com/diy/threads/any-saniflo-experts-on-here.496359/

I use to work on sewage pumps and used to laugh when we had a stoppage caused by a johnny wrapped round the impeller between it and the wear ring and acting like a brake shoe.Bob
