Saniflo installation

[TR1CKY]

I was wondering if anyone could advise on the electrical side of a Saniflo installation in an upstairs en-suite.

I know that an unswitched 5 amp fuse is needed but my question is, does this need a separate isolation switch or can the feed be taken directly from a spur from the floor ring main?

Also, what are the rules for positioning of the unswitched socket? (ie, how far away from the toilet / shower / basin etc).

Thanks in advance.

You certainly would be advised to have an isolation switch, and that must be at least 600mm horizontally from the edge of any bath or shower. However, if circumstances permit, there's no reason I can think of why you couldn't have a switched fused connection unit at that location (fed as a spur from the ring circuit), thereby serving both purposes (that's the arrangement I have for a Saniflo in my house).

I don't see the distinction.
A separate isolator is not mandatory but advisable and useful.

Also, what are the rules for positioning of the unswitched socket? (ie, how far away from the toilet / shower / basin etc).

If you mean 'socket' it must be over 3 metres from the edge of the bath/shower.

If you meant the fused connector -
Unswitched - anywhere except zone 1, not above the bath/shower tray.
Switched - outside the zones, more than 600mm from a vertical line at the edge of the bath/shower.
In both cases they must be suitable for the environment (manufacturer's instructions)

Thank you for the replies.

So, am I able to hide a switched fused connection in the cupboard that holds the basin (so effectively more than enough distance away from the shower) or is this switch better off on the outside wall of the en-suite?

Anywhere sensible (i.e. not likely to get wet, and not too difficult to get at when needed) that is >600mm from the shower. Mine is in a downstairs loo, and my switched FCU is, just as you propose, in a cupboard which holds the basin.

Kind Regards, John

Thanks John, much appreciated.

No, but you might like to read this.

And don't forget the requirements of 30mA RCD protection if not already existing on the circuit being spurred from.
Also routing of buried cable within permitted safe zones.
The manufacturers instruction will likely only recommend a unswitched fused spur but will/should also recommend RCD protection.

Thanks all (apart from Ban All Sheds - needs must I'm afraid!))

Is there a good reason behind an upstairs en-suite requiring a macerator?

Short answer, yes.

Long answer, yes because of the way the en-suite has been created, it's effectively in the middle of the house and the outside wall is on the boundary.

Rather than run a soil pipe some 7 metres to the next best outside wall through the bedroom or down into and through the kitchen, a Saniflo was the only viable option. Had five plumbers / builders all saying the same.

Seems a fair option in respect of distance and upheaval.

I had exactly the same situation with my ground-floor loo - which is right in the middle of a large house, very many metres from the nearest drainage, with routes involving solid floors in most directions. There was really no sensible alternative to using a macerator.
