Hello all,

I'm wondering what you would do when installing a new waste pipe from the kitchen. This will be a new 42mm pipe used for the sink, washing machine + dishwasher.

I was originally thinking about going into the gutter with an adaptor to keep things looking clean. Would be great to hear what you would do.

Waste pipe will come out of the wall anywhere on the left hand side.

Currently awaiting to be fixed.

Got this at the moment and can take it back if required.

Could someone also advise me on what those clay channel guides are called and are they still in use today?

Half Channels, rarely used these days outside of manholes. Would strongly advice not using them in a similar setup to whats already there, extend existing pipework to suit and connect to the drainage system using modern methods.

What I would do, looking at the pictures. Swap gulley in your pic for this one, https://www.screwfix.com/p/floplast-d530-back-inlet-bottle-gully/12051. Into the 'Back Inlet'. fit a 90° 110mm bend, short piece of 110mm pipe to get you to ground level (or just above), then fit an adaptor to accept the downpipe, https://www.screwfix.com/p/floplast-rainwater-adaptor-110mm/38593

New waste can be run to suit, cut a hole in the grid of the gulley to allow pipe to discharge into gulley, below the grid but above the level of the water. Connections for waste pipes to rainwater dont exist. mainly to prevent misconnections of grey water appliances into rainwater pipes, and subsequent discharge of waste water into storm drainage systems.
 
Those half channels were part of Victorian building regs - a waste pipe had to discharge some distance (18" ? ) from the gulley grid. But then one had servants to clean and disinfect such things ;)
 
Thank you Hugh / Nige.

Having gone over today, to prep everything, we also have the neighbours waste pipe which is also 42mm and exits into our gully. If the neighbour agrees (can't see why not), could we also connect their pipe in addition to ours?
So we'll have 3 connections 2x 42mm waste & one downpipe.

Neighbours.

Looking at your options and whats available could we also use the below to connect the waste pipes below ground? Any issues you see or do you have some other recommendation. Thanks again.

Can you get to the neighbours waste further back? Not much left there to get a joint onto, and I'd be concerned about the condition of the pipework just there. If you can cut it back above the rearmost elbow, then join onto it there, I'd extend that in a similar fashion to its current setup, and use the front bend to take it through the grid of the new gulley to discharge. Ditto with your new sink waste. Downpipe via back inlet.

Alternatively, fit a 110mm junction before the gulley, short section of pipe to take you to the wall, 90° bend and a waste adaptor in the top of the bend to accept the neighbours waste pipe.

Hi Hugh, i'll make some enquiries but their waste pipe is coming from the other side of our wall so guessing that it could be done. I'd rather not have to see or muck about with the neighbours waste... After all it'll be me that will end up cleaning it!

So what you're saying for the 1st option is that both 42mm will sit just under the grate after making 2 holes for those pipes.

The other option is also interesting but fitting 2 sets of 110 soil pipework in a limited area may not give us the flexibility. Therefore for this option are there any other options for joining multiple pipes?

Just keeping some options and an open mind as we may have to go with either option if it doesn't quite turn out right on the day. Though for some reason this one sounds more appealing as everything will be discharged directly into the sewer pipe without going through the gully...

assuming that also because the sink, washing machine and dishwasher has or shares its own trap so no smells should come through also?

Thanks again.
 
It's fine to connect a waste directly to the drain provided it has a adequate trap upstream, yes. That'll provide the defence against any foul odours coming back. Ideally I'd be looking to drop both wastes in through the grid of the new gulley, (easier and cheaper), but not sure if you'll be able to get the neighbours waste in without altering it.
