SInk waste disposal

[Harry Flashman]

I recently had my flat in London redone, and one oversight was the fitting of a sink waste disposal unit - I tshould have done this.

Needed for light waste only - no bones or heavy duty cooking stuff. Vegetable peelings, scrapings, that sort of thing. Has anyone retrofitted something suitable for this to their kitchen? How involved are the plumbing and electrics (plenty of electrical sources in my kitchen, as I have numeroud new sockets put in both above and below the worktops, when I had the rewire done.

One further complication - I have a ceramic Belfast sink. Can I fit the disposal unit to one of these, or not.

Ta, chaps...

From a plumbing point of view the disposer needs connecting to a 40mm waste pipe. There will be one under the sink, but one issue may be the height of this. WD's, once fitted with a trap, tend to be lower than the sink waste so check the height of this and the height of the ultimate destination (soil and vent pipe or whatever).
You certainly CAN fit one to a Butler sink, but you may well need to order a separate (deep) connecting piece to bolt through the sink onto which the disposer will mount.

ThakS Ferg. Actually, the waste problem is one I dealt with when I had the kitchen redone - the old sink did not drain properly due to too muck similariy in height. So the new waste outlet goes down through the wall to next doors outlet for the bath (bathroom next door), which is at floor level. So drainage should be good.

I shall look into this. Any recommended brands, anyone? My parents have a (decades old) Tweeny, that works fine to this day. Looking at the In-Sink-Erator too (despite the dreadful name).

I'd go ISE definitely, but look carefully at:
That issue with the thickness of the sink (longer adaptor available, and
How you're going to switch it.

Can use an air switch as could drill a hole through the wooden worktop.

The main problem seems to be that the ISE is not compatible with my sink - apparently you can't use them on a sink with a weir extractor; which is what mine, as a Belfast sink, has...
