The are usually illegal because the building deparments figure that it would be too easy for a homeowner to make a DIY addition to the system, without getting a permit or inspection. The biggest problem with dead ends that I have found is that they have a tendency to rust out due to the stagnant water.

: 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.
