Also, you might run into a problem where the shower arm is too short or angled too sharply for the shower head you bought. This can happen more with the wand-type shower heads and the wall gets in the way of the wand. You can solve this problem by making sure you buy a shower head that fits or installing an extension arm onto the main shower arm. You can find those the same place you buy the shower heads.
Plumbing reached its early apex in ancient Rome, which saw the introduction of expansive systems of aqueducts, tile wastewater removal, and widespread use of lead pipes. With the Fall of Rome both water supply and sanitation stagnated—or regressed—for well over 1,000 years. Improvement was very slow, with little effective progress made until the growth of modern densely populated cities in the 1800s. During this period, public health authorities began pressing for better waste disposal systems to be installed, to prevent or control epidemics of disease. Earlier, the waste disposal system had merely consisted of collecting waste and dumping it on the ground or into a river. Eventually the development of separate, underground water and sewage systems eliminated open sewage ditches and cesspools.
The projects we've laid out here are particularly simple, but plumbing can be tricky, so if you're ever unsure, don't be afraid to ask for help. These projects are all pretty straightforward, but you never know what will come up, especially with older homes. We've selected some pretty good videos, but do some research and find some other videos if something about your setup looks a little different. The Internet is a wonderful thing.
