With warmboard low temp radiant should I use a wax ring for the WC or a rubber one? Don't want any suprises with melted wax!

    wax options

    We've always gone by the rule that if you stay 12" away from the toilet you can use a wax ring, but I generally use the rubber one to be safe, especially on upper floors with large sheetrock ceilings.....architects just love to put a toilet right over the dining room ceiling!!!

    Honestly


    I have NEVER EVER heard of a wax ring melting due to radiant floor temps!

    John Barba of Wirsbo called a wax ring manufacturer and asked what the melting point of the wax was. It was MUCH higher than you would EVER run a floor temp at.

    In my area there are Levitt style homes with copper tube buried in the slab. I have seen DOZENS where the heating contractor ran the temps on the boiler to 180* with NO attempt at tempering the supply water. Those slabs cook in the winter, until the homeowner calls me and I fix it, and the wax rings DO NOT melt.

    Error on the safe side

    Grab some of the rubber types, available at plumbing supply outlets. I have never had a meltdown either, but then again never say never! It only takes one to ruin your day.

    Wax ring

    If it doesn't melt in a 120 degree truck why would it melt on the floor?

    on the other hand...

    heat doesn't do great things for rubber products, either. I don't have direct experience in the matter, I might lean towards the old wax ring. Maybe you can do an experiment. If you have an old pot, you could try boiling a pot of water and put the wax ring in it and see if it melts. If you have a thermometer, you could monitor its progress and see at what temperature it melts (if it does).

    put 160° F boiler water into the toilet.

    That's funny....

    the guy's at Watts claim that their rubber tubing will last FOREVER!!!!!

    I guess that means you aren't a fan of rubber tubing either.......

    That's okay neither am I :-)
