Went to B&Q to buy some 110mm soil pipe fittings for the
new en-suite (should've bought from Screwfix but you know the
millisecond you
confirm the order you come up with a dozen items that could've been on
it...)

I'm connecting some lengths of soil pipe that run approximately
horizontally for
about 3.5 metres, hence I need a straight coupling (the way it all
works out)

The black plastic couplings are sitting on the shelf at over six quid,
but I spotted
a brown (underground) coupling that looks identical (perhaps a little
shorter) that
was half the price of the black one.
The Scottish genes then kicked in and I bought the cheaper one.

But is this a decision that I will come to regret later - is there a
difference between the
two types of coupling?

Any help appreciated (I still have the receipt :-)

Probably resistance to UV light (just guessing)

Ta Rob. Another Google search threw up the thought that the brown
(underground)
fittings have thicker walls than the grey (above ground) pipes so that
they
can withstand more ground pressure?

But why buy a six quid fitting when there's one there for half that
price and
it will do the same job (or will it)?
