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 .
Using corrosive chemicals to dissolve a clog is like throwing a grenade down a gopher hole. Instead, Wroblewski recommends flushing your drains weekly with a half cup of baking soda and one cup of vinegar. Let it fizz in the drain for ten minutes, then pour in four cups of boiling water. Find out about the plumbing nightmares that will make you cringe.
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.
I had 207 Plumbing come to fix a leak in my ceiling. It's a terrible, terrible company to do business with. He came and fixed a broken pipe in the ceiling, and I asked him to check the rest of the pipe to make sure that nothing else was broken, he said everything was OK and charged me $219.00 for 45 minutes and left. Never cleaned up his mess. I went to clean up the mess after he left and found there was more damage to the pipe. I called him to come back, which he did. He looked at the water coming down from the ceiling, into a light fixture and said he had another job to go to and couldn't come back until next week. He also wanted to charge me $350.00 to come back. I told him that was too much and he said he would make an exception and only charge me $219.00. Now I have major damage done to the ceiling, the light fixture and the floor. All of this could have been prevented if he had stayed and fixed the problem. I will NOT hire him again.
