Todd did an amazing job, and fixed a problem that could of been devastating. Replacing a leaking water heater and also a replacing a failing, leaking main shut of valve. The possibility of major flooding was a real danger It was a 12 unit townhome which made the job even trickier, as water had to be shut off to the entire building while he fixed the valve. Todd, replaced them quickly and expertly, without a hitch. Plumbing repairs are never fun for a homeowner, but these people (especially Todd) do great work. It is definitely a weight lifted off my chest.
The thicknesses of the water pipe and tube walls can vary. Pipe wall thickness is denoted by various schedules or for large bore polyethylene pipe in the UK by the Standard Dimension Ratio (SDR), defined as the ratio of the pipe diameter to its wall thickness. Pipe wall thickness increases with schedule, and is available in schedules 20, 40, 80, and higher in special cases. The schedule is largely determined by the operating pressure of the system, with higher pressures commanding greater thickness. Copper tubing is available in four wall thicknesses: type DWV (thinnest wall; only allowed as drain pipe per UPC), type 'M' (thin; typically only allowed as drain pipe by IPC code), type 'L' (thicker, standard duty for water lines and water service), and type 'K' (thickest, typically used underground between the main and the meter). Because piping and tubing are commodities, having a greater wall thickness implies higher initial cost. Thicker walled pipe generally implies greater durability and higher pressure tolerances.
We actually have our own guide on this, but the above video from Lowe's is a good basic guide too. Do make sure to read the installation instructions that come with the faucet, though. Sometimes, there are important variations. We've only included a video on kitchen sinks here because the process of installing a bathroom sink is largely the same. However, you can always check out this video from RONAinc if you want to see the process.
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 when the sewage is splashed during the repair. The plumbers skin during the repair does come into contact with the sewage water. The owner of the toilet might not report to the plumber they have already tried Drano a highly caustic base .
