Does anyone happen to know the pressure rating of solvent-weld
overflow pipe (40, 30, 21.5 mm sizes) labelled "MuPVC BS EN 1566 CS
B"?

Thanks.

How high do you need it to be?

Enough to withstand diet coke and mentoes? It's either 21.5 mm
overflow or 20 mm electrical conduit that snuggly fits into the top
of a coke bootle...

Why not google that standard, you might be lucky and find enough
information without having to pass a paywall.

Well actually, I'm wondering if I can use it to do a scaled-down
version of William Gurstelle's hairspray-powered spud gun.

Overflow pipe is not pressure rated.

You can buy PVC and ABS systems that are, ABS being the better.
Quite costly ISTR.

Overflow pipe is usually polythene crap.
So all you can do is suck it and see.

Probably OK -

If in doubt, put it inside a bigger pipe to contain the shrapnel

They are intended to work at atmospheric pressure, but are nominally
considered to be rated to 0.5 bar. For pressure resistant water pipe you
need BS3505 pipe. In the sizes you mention, most will be Class E, which
is rated to 15 bar, although 1.25" (42mm OD) is also available in Class
D, rated to 12 bar.

Perhaps not if it is marked as PVC though. OOI, what would you use to
solvent weld polythene pipe Harry?

So all you can do is suck it and see.

Probably not the best way to test a pressure rating.

The PVC/ABS solvents don't work on it.
You might try the solvent they sell for the cheap pond liner repairs.
Or superglue.

I asked because the OP specifically stated it was solvent weld pipe and
you went on to suggest that overflow pipe is usually polythene, which is
one of the most solvent resistant plastic available, so nobody would
sell it as solvent weld pipe.

Most overflow pipe I have come across is push fit.

Still irrelevant to a query that is specifically about solvent weld pipe.

The stuff I have is labelled "PVC" (some of it says "MuPVC").

Thanks, I'll look for some BS3505. (I think it only needs to go up to
7 bar.)

It is usually coloured grey and should be available from builders' or
plumbers' merchants, but may not be in the sheds. I have had good
service from these people:

There's no *only* about 7 bar. The volume of gas pressurised also needs to
be considered if you're concerned about hazards.

But seeing as the OP specified solvent weld pipe, what is the relevance
