Could someone please recommend a plumber who is capable of working under a double-wide to replace original piping with PEX pipes (to prevent ruptures in winter should pipes freeze)? I mention this detail because many plumbers can't or won't do this kind of work, understandably since bad knees when older, it's claustrophobic, etc. It IS possible to get under it since I watched the inspector crawl up and down the whole length of it, although he got kind of dirty. So, please recommend plumbers who do this kind of work, preferably something reasonably affordable (if for example it turned out to be a $3000 job, I'd be happy with that).
Note this is urgent because it is related to a house purchase that's about to happen. Thanks!
