so, after spending 5 hours cleaning up in the basement again today, I have this to say:
If the darkroom is flooded, it's probably the trap on the street, call Scottish Water to get it fixed.
BUT...... if the watery goodness is coming out of the trap under the new toilets (1st stall) then it's probably our problem (as it was today) and call Ken or Chris ASAP to sort it out. it was mega gross today, Ken came & helped out and then the lovely scottish water guy fiddled his report & helped us even though he wasn't supposed to.
Would anyone please like to make some signs about not sticking bad stuff down the toilets? as humorous as you like, maybe describe the look on my face after 5 hours of cleaning up poo...
