Have a look at this photo of my waste stack at the point where it joins the clay rest bend: http://i1298.photobucket.com/albums/...ps8ae7g62j.jpg



Two questions:

1. The clay rest bend is cracked. The bit between 3 and 6 on the clock if you looked at it from above is a bit loose so it's abviously cracked to below ground level a bit. It's been like this for years without any obvious problems and I'm wondering if I should just fill the clay collar with fresh mortar to make the plastic pipe water tight again. Or do you think I should replace the rest bend (doable but I'm not keen)?

2. What's that ridged part of the plastic pipe called? If it's a fitting can you link to one on screwfix or similar so I can see it please? I can't even tell if it's part of the pipe or a separate fitting. I assume the ridges are to make sure it beds well in the mortar.

I would either fill it with a 3:1 cement mix and forget it, or bite the
bullet and dig the lot out and rejoin the clay pipe at a suitable point
beyond the crack. Depends on how much work you want to do.

If it ain't leaking Id be inclined to chop the last of the clay
verticals away make a mould out of some plastic or wood sheet and cast a
lovely concrete collar.

Thanks. Any idea what the ridged part of the plastic pipe is? It looks like it's part of the pipe but might be a fitting. I can't find any pipe being sold with those ridges on it but this is old pipe. I can see the point of it is to anchor it in the mortar (I think) but there must be a modern version.

The modern version has rubber ridges for want of a better description.
I guess the plastic ridges are to firstly hold the plastic in place in
the clay pipe and secondly to anchor it into the mortar.

Digging out the cracked piece is not worth bothering with.
Yes, you'll have a nice new plastic 90d bend for your plastic stack to slot
into, but the joint between plastic and clay will now be underground at the
bottom of the bend. Even if you replace like for like and get clay (still
available), you've got to join it to the next piece underground, crack or
break that during replacement and you could be digging the next three
drainpipes out.

I'd just give it a good clean and repoint with strong mortar, 3:1
sand/cement.

Fill it so that it's flat all the way around and then while the mortar's
still wet, put an angled mortar collar up about an inch all the way around

It's probably just a plastic to clay connector of some kind, maybe still
available maybe not.
If the gap where they meet is big enough for mortar to get through when
you're pointing, you may want to run a bead of silicone around it first so
that no mortar gets into the rest bend. 3:1 mortar sets hard and will stop a
turd in it's tracks, resulting in a blockage.

+1 no question. Trim with angle grinder rather than bolster!

I'm wondering if that is a bodge using a flexible toilet pan coupler.
The ridged part is the flexy bit, maybe?

I wondered that, but under the grey and black paint the actual
plastic looks like orange/brown so it must be a proper
underground fitting. Maybe one intended for connecting to
cast iron ?.

The big question is why is the collar of the old glazed pipe
so large ?. Normal foul drainage is about 4 inch, so the collar
would be about 5 inches. This looks more like the collar of
a 6 inch pipe.

Can the photo be re-taken with an inch ruler laid across the
collar so we can see the actual diameter ?.

The ridged part is something like this, which is what I'll be using on the new pipe: http://www.diy.com/departments/flopl.../218347_BQ.prd

As for the size of the clay collar, this is some sort of bodge by whoever installed it because it goes directly to a manhole which is barely under surface level. So it can't be a proper rest bend,the depth is much much too shallow. It certainly won't pass any modern regs. But it's caused no problem in the last ten years so I'm going to repair as best I can and leave it at that. The plastic pipe, by the way, is a standard 110mm grey one which has been painted over black!
