I had a plumber do some work on a remodel I am doing. Where the main line
comes in, it was split into an irrigation line. He rerouted it and where
the irrigation line was tapped into the main line he capped it off but he
didn't have a sleeve (which may not be the best solution with such a large
pipe anyway - never seen a large sleeve with stops). and didn't have the
right size cap so he put an reducer in, I think 1 1/4 - 1 if I am not
mistaken and then used a 1" cap. This dead end is about 4" long. Is this a
problem in terms of standing water causing a problem with the potable water?
I know buildings leave stub outs all the time for future remodeling. In
fact I have 2 3/4 inch lines that have stubouts that are about 12 Feet deadending
in a crawl space. I may put in a bathroom at some point and did not want to have to rip open the ceiling in a room. I also know that air hammers use the dead end principle. But why are some people against it and in some parts of the world dead ends
are out of code compliance. Many plumbers feel that these dead ends are a area where bacteria can grow and contaminate water. Is this true? By the way, doesn't the pressure change in ones home fairly regularly allowing for the drainage of dead ends. Do I have a problem having this type of dead end or should I just cover it up and forget it. Thanks.
