Are 90 degree soil waste bends available?

[me]

I ordered a 110mm waste bend off eBay which was advertised as 90 degree, which is what I want, but got sent a standard 92.5 degree bend. So does a 90 degree bend in waste fittings like this even exist?

I need one because the bend will be horizontal and a 92.5 will angle the pipe away from the wall (by 2.5 degrees)...unlike a 90 degree bend. I can bodge it to make it how I want but I'd rather have a proper 90 degree bend if they exist.

I'm just not sure if I've been sent a wrong part or not.

I think they're generally 87.5/92.5 to maintain the fall, you might need
to use one of the 0-90 degree adjustable ones if you actually need 90
degrees.

but they're not especially compact

Isn't there enough "flex" in the joint (and the pipe) to be able to
force it back to 90 degrees? ISTR that I had a similar situation some
time in the past and was able to sort it out without a special bend.

But if there is a proper 90 degree bend then I'm going to send the one they sent me (a 92.5 degree one) back as they advertised it as a 90 degree.

There's usually 2-3 degrees of slop in those anyway - is it solvent weld
or push fit?

Well the 90 degree bends do exist. Here's one: https://www.mkmbs.co.uk/prodl009195-polypipe-soil-vent-110mm-90-close-couple-bend-grey-swb47/

Pity they only do grey though, I need black.

Building regulations do not allow a 90 degree horizontal bend without
installing a rodding point - typically a man hole - IIRC.

So they are not sold.

Oh its above ground?

Then you should be able to get it with a rodding pint installed.

http://www.ebay.co.uk/itm/Black-Soil-Pipe-and-Ring-Seal-Fittings-UPVC-110mm-External-Or-Internal-Use/321647272032

and select 90 degree access point.

This: http://www.builderdepot.co.uk/polypipe-close-coupled-single-socket-solv-soil-bend-90-deg-110mm-black.html

is the actual, genuine 90 degree bend I want. So the eBay one is going back.

No, that site shows stuff with the 90 +- 2.5% bend. As I said, you need
a rodding eye if its 90 degrees, which that is.

I've never been very good at spacial perception, so perhaps I'm having
trouble with something that other people find obvious. However, I don't
see why you can't maintain the fall with a 90 degree bend? You just
rotate the fitting slightly, and you can get anything between a 0 and 90
degree fall?

[Bob Minchin]

you can only do that with a pair of bends but will get an offset.
A pipe running at 2.5 degrees off horizontal will make a 92.5 degree
angle with the stack hence the angle of the bend there is no possibility
of rotating the fitting to change that angle.

[Bob Minchin]

I'd have put a small wager on 90 degree bend being unavailable but that
one actually says 90 degree in the moulding if you zoom in on the photo.

I've learned something from this thread!

[The Natural Philosopher]

From a horizontal pipe. yes.

Not from a vertical.

though wherer 82.5 fits in I cant quite see at this point in time

(More or less) *horizontal* pipes are supposed to be laid with no bends
so they can be rodded, therefore where a direction change takes place
you have a rodding point (above ground) or a manhole chamber (below
ground. Pipe runs between are straight with a 2.5 degree fall.

Above ground you generally want to get TO the ground using vertivcal
pipes. If these have to dogleg they need the horizontal to have fall.
Usually that's 45 degree, but it can be nearly horizontal.

There are quite a few single socket 90 bends about but you really need
to check that they are actually 90.
