I bought this house in 2002 and put in some additions which included running copper pipe to a powder room, a laundry room, and a master bathroom. In the past year or so I have been 'blessed' with several pin hole leaks in some of the copper piping. When it happens I remove the old pipe and replace it with new copper. But that's getting annoying! Some of the piping is in a crawl space that I know I can't get into and I'm just 'waiting to see a leak there.. I recently had to replace some piping behind the wall and above the ceiling in the powder room. Is there something I can do with my existing piping to stop the leaks? Thanks. Rich

Thinking about getting a sewer jet kit for my pressure washer. It's a Craftsman, 2700 psi, 2.3 gpm. There's lots of options, but would you go with a 1/8" hose or 1/4"? The drain pipe giving me issues is 1.5" in a kitchen. I'm thinking the 1/8" would go in easier, but would that smaller size cause issues with my pressure washer? The hose on the pressure washer and gun is 1/4. Thanks a lot.
