I'm going to be a *lot* more careful in the future but given that
everything is getting revamped, I was wondering about a grease trap
for the drain. A quick seach just seems to throw up catering sized
traps. Are there any smaller ones for domestic use?

Now you know why I tip caustic down at regular intervals.

Can't see why you'd need to. You don't have to put insoluble fat down a
drain. If you don't keep it for re-use - as our parents or grandparents
used to do - put it in a container and out with the rubbish.

There is always some tip off that is too contaminated for reuse.

Anyway my grandmother used to keep everything and every time I ate her
'left overs' I had the squits for a week.
