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.

My hot water heater ruptured at 2030 on a Tuesday and Justin along with Trey were at my house at 0830 the next morning. They were consummate professionals the entire time they were in my garage. They were courteous and polite and worked as hard as they could on a difficult removal and replacement. I can't thank them and Atomic Pluming enough. I'll call them for anything in the future and you should too!


Try a plunger: If it's a double sink, use a wet rag or rubber stopper to block the other drain. Place the plunger directly over the drain until it forms an air-tight seal. If you have trouble forming an air-tight seal with the plunger, run it under some hot water to make it more flexible. Move the plunger up and down to dislodge the clog from the drain.

A handyman walked away from the job after cutting off the water to my mother's house and removing a toilet. He did this while I was attending a funeral. My mother is 87 years old. Called Atomic Plumbing and Ryan Dean responded Saturday afternoon and restored water to the house. He finished the job Sunday morning. He was the nicest, courteous, neat plumber I have ever met. I can't say enough good things about Atomic Plumbing from the employee who took my call to Ryan Dean's excellent service.
