My plan for a kitchen move/extension has a critical dependency on being able
to tap into an internal boxed-in soil stack for drainage. Having drilled a
hole in the boxing today I've thankfully been able to confirm with a
borescope that there's sufficient means and room for a strap-on boss to be
used.

Given the soil pipe appears to be Osma I figured I might as well go with one
of their strap-on bosses[1] too as this isn't a connection I can afford to
get wrong. Too this end, I've noted from Osma's design guide[2] that
'Solvent Cement Filler' should be used. Presumably this is given the nature
of the joint not lending itself to 'standard' solvent cement?

However, I've since learnt that not only does hardly anywhere seem to sell
this stuff (why not?) but also that it's around £20+ for a 200g tube!

So, I was wondering if there are any alternatives (e.g. other brands,
standard cement, etc) or should I just swallow the cost on the basis that if
that's what's required that's what's required! Can the cement filler be used
on 'normal' connections too? I was also wondering why it's in a tube rather
than a tub-with-brush which I assume is easier to use?

I have also considered whether instead of the strap-on boss if I could cut
the pipe and insert a bossed pipe connector[3] in between but I'm not sure
if there's any slack to push the upper pipe up to allow this to work.

Solvent cement is what is used on some waste pipe fittings. (As opposed to
push in/Oring and the compression type)
I have used this in the past with no trouble.
