Ah, right. A two-foot diameter soakaway isn't a soakaway at all
unless you're on the kind of broken rock that doesn't need it anyhow.
Tell all your friends who did the job.

What actually happens at present? Do you get puddles, or squidgy bits
of ground where you don't want them? Where I'm heading is, does it
actually matter? Most people don't have separate drainage for their
greenhouses, and never notice any inconvenience. A minor patch of wet
ground could be cured simply by laying a deepish gravel path. How
often do you have so much water coming _out_ of the greenhouse?

Hi,

the problem is a little bit more severe than that, as the sump whole isn't
draining at all, the water is just sitting in the pipe.

it doesn't get used very often, only for a bit of watering etc....but as the
sink is underneath the concrete base of the greenhouse, its difficult to
work on - hence the idea for the work round

very low volumes i agree, but still gotta go somewhere - sorry if previous
post was unclear.

cheers
