    Angry Question: D3309 Grey Pipe, is it safe?

    I am trying hard to find out if this kind of pipe is safe. It has been withdrawn, yet my apartment is using it for hot and cold water. I think it is breaking down. We do not have chlorine in our village well water.

    Thanks

    Robin

    It's polybutylene pipe. No if ands or buts about it. Zurn, owner of the Qest brand, does make QestPex pipe, but the PB2110 identifies it as polybutylene. Now that that is cleared up.

    I seem to recall that the issues with PB were two: one had to to with the fittings, but then long term there is a problem with pinholes, but that was related to chlorinated water, so you should not have a problem.

    Jimbo you are right! The initial problem was with the actal fittings but later the tubing itself was breaking down from chlorine content of the water supply.

    If you are on a well (non-chlorinated) and you haven't had problems, why fix it if its not broke?

    Thanks for replying. We took off the tap fittings in kitchen, and bathroom and flushed the water through. About an hour later I could not smell or taste metalic anymore. A floral smell was in water instead.hmmm. Test results come in soon. Thank you Robin
