    Default Identify type of pipe

    The pipes shown on top of the water tank are everywhere in the house. No signs of leaking.
    Is it plastic, if so, any known problems with these pipes.

    Looks like CPVC.

    I agree w/ CPVC. Not a fan of epoxy welded joints for water, but it's legal and it does work. At least you have reportable work in that photo.

    I have only seen it used as the discharge pipe. There was some writing but was illegible.

    Its copper and CPVC mix, must happened when copper prices when crazy way back when....

    Thank you kindly

    It was common for a few years around 1985 -95. I used it and liked it, but had a few joint failures, like a hose bib that flew across the yard one day. That was from people pulling too hard on the hose. It is a reasonably stable product, and it can stand heat.

    I think its in the article posted above, they run it for a month in super high temps and p. My read on it is that if it was installed correctly the first time, all things being equal, it should last as decsribed.

    That white sheathed cable coming down in the back is the main ground, its at least 6AWG and connected to the water line. First Ive seen them sheathed. Home built in approx 1958.

    Also the armored cable needs the proper connector with an anti-short bushing installed.

    Since the armour went right inside there is no reason for a bushing ...the tank will no doubt be replaced shortly...there were some other issues as well, rusty slurm seeping out of the side and it was installed in 1998. Almost done, budget for replacement.

    Hey Stephen, that tank was installed in '02, per the writing on the lid.

    A bushing is still required there, or rather, a cable clamp. Without the clamp, the armoured flex can be pulled up, exposing the unprotected wires.

    CPVC can go directly to the water heater. That part's OK.

    John

    I only use the serial # on the the data plate . And yes the wire should be clamped.

    Thanks for the tune up ...

    FYI repairs made on CPVC hot water piping need 6 hours to cure before pressurization.

    Yea; that's what I mean't about by there at least being some reportable work for Steve earlier. I admit to being chemical/s parnoid, but "Chlorinated Polyvinyl Chloride" simply does not sound homogeneous w/ drinking water to me. More like a "go to" ingredient in Dr. Kavorkian's medical bag. Legal and safe are not always the same thing in my personal handbook.
