Hooray!
My (ancient, late 19th century-installed) sewerage pipe has just been unblocked!
Now I can have a shower, flush the toilet, wash the dishes!
What a relief.
The things you take for granted ....
Just spent an hour & a bit out the back with two very nice young plumbers who did the job.
I hope I don't need to see them again for a long, long, time!
