Pro Plumbers

Present-day water-supply systems use a network of high-pressure pumps, and pipes in buildings are now made of copper,[25] brass, plastic (particularly cross-linked polyethylene called PEX, which is estimated to be used in 60% of single-family homes[26]), or other nontoxic material. Due to its toxicity, most cities moved away from lead water-supply piping by the 1920s in the United States,[27] although lead pipes were approved by national plumbing codes into the 1980s,[28] and lead was used in plumbing solder for drinking water until it was banned in 1986.[27] Drain and vent lines are made of plastic, steel, cast-iron, or lead.[29][30]
Another way to avoid a service call from your plumber is to make sure the outside faucets are turned off in the winter and make sure you disconnect the outside hoses. You need to shut the water off from the inside. Then, open the valve on the outside to let the water that’s in there drain out—you switch both of them to the opposite direction so one is always closed and one is always open. We have to fix tons of these in the spring mostly because people leave their outside hoses connected and they freeze up. The repair could cost $100-$200 or more. Another tip would be if you’re going away for any length of time, like on vacation, turn off your water. If on any of those days the temperature drops below freezing, have someone check in on your house. I’ve been called to homes where the family returned from vacation, and there was water flooding out from the front door.

When a person has a blockage in their sewage system they often try to fix it themselves by adding an acid or a base such as Drano in an attempt to dissolve or dislodge the problem. These chemicals can get into the plumbers eyes [14]when the sewage is splashed during the repair. The plumbers skin during the repair does come into contact with the sewage water.[15] The owner of the toilet might not report to the plumber they have already tried Drano a highly caustic base .
