flexible copper for baseboard

that the pressure on your water heater would be considerably higher than your baseboard.... I can't think of anything that would cause problems.

    flexible copper for baseboard

    Hi guys, I installed a new section of copper 3/4" baseboard but because the crawlspace below was partial blocked I was not going to be able to solder a fitting so I used a piece of 3/4" fleexible copper tubing that is made for hot water heaters. The flex has been hooked up for a few weeks now and I still don't have any leakes or problems. Will I start to have problems in the near future or is this acceptable? Thanks for your help. Scott

    fllexible copper

    Just remember that copper is a work hardened metal...the more it works the harder (and more brittle) it gets. I wouldn't trust that "accordian" tube for too long. Can you use a piece of soft copper or pex in its place? That would be a more permanent fix in my book. My two pennies worth.

    As long as you

    soldered it in place. I'm not sure the gasket included with the threaded versions is up to the temperture it might see in a boiler loop.

    I'd guess the wall thickness is as good or better than the tube in most copper fin tube baseboard. It seems to be less then "M" grade?

    I think Slant Fin still offers a flexible connector like that.

    Watts Radiant Onix makes a nice flexible connector, if you have the fittings and clamps available. It never makes noise if it rubs on wood :)
