  • How to replace cold water pipes for toilet?

    I'm planning to change the existing toilet with a newer model and noticed the pipes are rusty.



    Any idea about how to replace the cold water pipe? Do I need to remove part of the tiles?

    That rust looks like it's from the escutcheon, not the pipe.
    Just replace the escutcheon, supply valve, and supply tube.
    The pipe looks OK from here.

      Split escutcheon & chrome cleaner.

        Looks to me like the packing nut on the valve is leaking on the escutcheon. As suggested above get a split ring escutcheon or chrome cleaner and tighten the packing nut 1/4 turn.

          If you're going to the expense of replacing the toilet why scrimp on trying
          to salvage the escutcheon and valve? Just do it right and replace.

            Is that a galvanized riser to the straight stop? Is that an IP stop? I think it's copper painted to match the escution.

              Good call, it could be a packing leak. But also, with pipe coming up from the floor, it could just be condensation forming on the pipe in the summertime and running down onto the escutcheon. In any case... I wouldn't bother tightening the packing nut, I would just put in a new high quality 1/4-turn valve, and a new one-piece escutcheon while the valve is off.

              Since the floor is black tiles, if you spray the new escutcheon with gloss black Rustoleum it won't rust, even if it is just from condensation. Give Rustoleum out of an aerosol can a LONG time to dry, at least three days -- longer if you can.

                It's a "tinned" stub. Some guys do it as a finish on the stub. I don't particularly care for it.

                Gonna' make it a little harder to get that escutcheon off and back on. Unless you've been to tin snip butcher class like I have. Or the split ring.

                I agree with Jim. This time....

                  As the packet nut on the valve is leaking you should go for Split escutcheon & chrome cleaner and tighten the nut by quarter.

                    you guys are genius. every time I tried to open or close that shutoff valve, it would leak some water from the stem. I'm going to tighten the nut 1/4 turns. before I asked the question here, I went to HomeDepot, staff there said I cannot fix that valve and told me to replace the shutoff valve with a mini ball valve (compression ring connection).

                    As for the pipe, I'm pretty sure it's soldered somewhere below the floor so replace it is possible but difficult. I'm going for Split escutcheon & chrome cleaner as suggested.

                    Thanks everyone.

                      Asking for advice from home depot, is like expecting mc donalds to get your order right, the second time.
