One a day, plus iron

If you are not up to speed on the overall shittiness of Quest Pipe, you can take it as read that Quest Pipe is a shitty product that will fail, many times. There were lawsuits about it and everything. Now, as you know, Bob, I do landlording stuff in my day job. One of the buildings that we have is called 321 because that is its street number. Anyway, there is Quest pipe in 321. It has failed repeatedly since the 1980's when it was installed.

( But... if it's a shit product that has failed repeatedly, why haven't you torn it all out? )
