Hi...I am the Facilities guy at a 100 year old school (it was once a hotel many years ago)...I don't have much plumbing experience...every so often we get hot water coming out of the cold water taps...usually it is lukewarm, but lately it has been very hot.
Possibly, this latest problem dates from the time 6 months ago when we had our dishwashing room done over...the sinks where it happens most back up to the wall that has the dishroom sinks.
We have pretty good plumbing drawings, altho some are 30 years old.
Any ideas on how we can start to track down where the problem is?
Also, I don't mind hiring a pro, but I would like some ideas on how to start him/her off in the most efficient way.
Thanks for any help,
Yours truly,
Getting Steamed
