as this was a whole house installation, including radiant heat, i would have expected a higher level of plumbing knowledge. our pvc pipes (which i regret) were installed in such way as to forever impact our water use at the sinks. the cold water pipes were placed immediately beside the radiant heating. we never have cold water coming from our faucets except in summer when the heating is turned off. i find it amazing that a plumber would make such a mistake as this. he was not very professional and i found him unpleasant to communicate with. his attitude whilst working here was not great, i felt that he had absolutely no care for my home or the finished product. we paid him upfront for a start to finish price per water line hook up, and i feel that he did not complete the job - hooking up faucets and appliances to water lines. he claimed after the fact that this was not included. we did not have him back to finish our hookups.
