My tub/shower unit was leaking onto my downstairs bathroom ceiling. The tub/shower unit is back to back with a stall shower. When we built our house we did leave a 12 inch access that we built a removeable cabinet for. Apparently the shower head unit is leaking where the copper pipe connects to the wall. This is evidenced by green corrosion. Is there a way of using compression fittings to fix the problem, as I don't get warm and fuzzy at the thought of soldering. Also, there are no shutoff valves on either sets of plumbing. Can/should I install valves on all the lines? Thank you in advance.:rolleyes:
