Number B: Links for Steel as well as Plastic Pipe


Many houses have actually galvanized steel or plastic (CPVC) water supply pipes. Galvanized steel pipelines are difficult to replace. We suggest that you eliminate the pipes back to the nearest tee, screw on a plastic-lined galvanized nipple area and also finish the links with copper as shown in our photo series.

As a result of possible warmth accumulation, keep plastic pipe at least 6 in. far from the air vent and container. Make a shift from plastic to copper with a special coupling that’s offered any place CPVC is offered.

Flexible copper connectors are simpler to mount than strong copper, particularly when the existing pipelines as well as the container inlets do not align. But not all local codes enable them. If yours does, take unique treatment not to pinch or kink them. You can get a leak.
