Hello, Have had a few pinhole leaks in house Copper water pipes. House is 35 yrs old, and was apparently built with the thin wall Type M Copper pipe. Hope to avoid re-plumbing the entire house. Anyone know anything about those epoxy internal coating applications for house pipes? Apparently there are a few outfits that do it, as shown in: [url=http://www.toolbase.org/Technology-Inventory/Plumbing/epoxy-pipe-lining]Epoxy Pipe Lining[/url] Is this a "popular" or "common" approach ? Is it safe, in that your drinking water would be in contact with the epoxy ? Haven't checked, but is it Approved by most Towns ? How do they handle the 90 deg. bends, and the faucets, etc. What are the negatives, caveats, etc. ? Just curious: is Type M, the thin wall stuff, still "Legal" ? Still used much ? Where ? In 35 yr old houses, are pinhole leaks fairly common ? What (usually) causes ? Thanks, B.

O Wise Ones, Our washer drain recently started overflowing during the drain cycle. It was working fine for about a year. I called in a plumber and he used a 75 ft snake and didn't catch anything. He said he didn't have the equipment to help me any further and asked me to get hydrojetting done. I have tried using a liquid plumber kind of drain cleaner but that hasn't helped either. No other drains in the house are overflowing, so I don't think the problem is too far from my washer. Does anybody have any ideas that I could try out ? Thanks very much! Vivek
