    Default Behind the wall tanks? Will they last 20 years?

    I want to redo a tiny bath and gain space by installing a behind the wall tank and wall hanging toilet.
    Is it realistic to think I can install this and tile over the wall and it will last forever and a day?
    Or should I expect to have to open the wall every couple of years?

    I see this gerberit tank and carier

    Not from experience, but from what I've heard, you can do any maintenance through the 'cover' in the wall, and not have to tear into the wall itself.

    The in wall tanks are built to the same standards as any plumbing that is going behind a finished wall. The maintenance items on the tank (fill and flush valves) are accessible through the area covered by the rectangular plate for the flush buttons. Pull up a set of instructions from the mfg Web site and you will see.
