I have a 35 year old home that has copper water pipes in the crawl space. I have had a few leaks recently where the copper had corroded through. So I want to get a rough ballpark idea what it might cost to replace all the copper with pvc in the crawl space under my house. It is about 1200 sq feet with 1 and 1/2 baths, kitchen and laundry room in the Columbia, SC area. Any info would be appreciated.
