Hi,

Here's a daft question: I see Toolstation sells two types of solvent
weld bend.

A 90 degree bend:

and a 92.5 degree bend:
http://www.toolstation.com/shop/Plum.../sd2885/p70029

What's the difference and when do you use either type?

To answer my own question, the obvious difference is 2.5 degrees. I am
guessing that 92.5 degree gives a slight angle to the pipe to aid
drainage but in that case, what do you use the 90 degree bend for? Is
that for connecting a vertical pipe to a trap perhaps?

TIA

92.5 would be used between a horizontal pipe (actually with a 1:40
fall) and a vertical pipe. 90 would be used for a bend in the
horizontal plane.

A normal 1:40 slope requires and angle of only 1.4 degrees.
2.5 degrees gives 1:23 - that sounds rather steeper than normal.

but in that case, what do you use the 90 degree bend for? Is
that for connecting a vertical pipe to a trap perhaps?

Horizontal bends?

They can help with, for a good example, coming through the wall to a stack
pipe, helping to get a good run angle to the stack branch. That little bit
extra angle stops you forcing the last bit in. Or if there is a change in
height or direction from old to new positions on appliances, they help in
allowing the existing pipework to used.

It's amazing how a couple of degrees at one end of a length of pipe can
dramatically change where the other end of the pipe goes.

So my next silly (?) question must be: why is there only one type of
bend in push fit and compression waste (as far as I am aware)?

To answer my own question, I think it is because there is sufficient
play in compression and push fit joints to insert the pipe at either
90 or 92 degrees?
