Hi. My first post so here goes. Two questions for you:
(1) Is fitting a shower unit a one-man job for a professional?
(2) Another 'professional', when we had a new kitchen fitted, took the waste pipe from the sinks and cut it into the Soil Stack pipe (right words?). He simply cut a hole into the Soil Stack pipe, pushed the pipe through the hole and then sealed the hole with silicon. He cut the hole too high and as a result the waste pipe sloped upwards to the hole.
Another plumber has just fitted the special adaptor and says its now AOK but both the pipe and the hole are in the same place so won't the waste pipe still have an upward slope to the hole? (Hoping this makes sense.)
