Recently the toilet backed up and I tried to snake it. No joy. Called a plumber and found the old earthenware pipes had collapsed. $5500 later...
That included reworked bath, shower, basin, toilet, and floor piping, replaced gas line 'water pipe' with copper, and two extra yard taps.
Took two guys 8 hours. Nice money. But still feel it was worth every penny. It was a shitload of work, most under the bathroom floor & house, or within a great bloody hole beside the house.
Still, $5500!
[thinks... did I already tell this story?]
