What type of hanger must be used when supporting copper piping?
Pipe hanger used on copper or brass pipe should be made of the same material or protected from the effects of galvanic corrosion by using an insulating material. (EX- A steel hanger will eventually corrode through a copper pipe.)
What is primary pipe support?
A primary support connects directly to the pipe. A secondary (or structural) support is connected to the foundation or structure and supports the primary support. The second way pipe supports are classified is by their construction.
How many types of support are there?
There are five basic idealized support structure types, categorized by the types of deflection they constrain: roller, pinned, fixed, hanger and simple support.
What are the plumbing standards for drinking water?

Water service pipe shall conform to NSF 61 and shall conform to one of the standards listed in Table 605.3.
What kind of pipe do you use for water supply?
More recently, various forms of plastic have replaced copper as the favorite, though copper pipes and fittings are still widely available. Due to the price of copper and longer labor needed to install, many builders have switched to alternative water distribution piping, especially PEX.
Is it against the law to install a water supply pipe?

What kind of pipes are in a water tank?
Most water tanks contain an inlet, outlet, and overflow pipe made from steel. The inlet and outlet pipes should be two different pipes if the tank is used for drinking water, because a silt stop needs to be placed on the end of the outlet pipe to help eliminate sediment and contamination.
What kind of pipe support do you use?
Our supports have been specified and installed on major water treatment, pharmaceutical, process piping, petro-chemical, hospital, and school buildings as well as many other industrial projects throughout the world. Carpenter & Paterson, Inc. products and the “Witch” trademark are synonymous in the pipe support industry for quality.
Where are potable water pipes not to be located?
Potable water service pipes shall not be located in, under or above cesspools, septic tanks, septic tank drainage fields or seepage pits. Where soil or ground water causes contaminated conditions for piping, analysis shall be required in accordance with Section 605.1. 604.1 General.
What do you need to know about plumbing standards?
Each length of pipe and each pipe fitting, trap, fixture, material and device utilized in a plumbing system shall bear the identification of the manufacturer and any markings required by the applicable referenced standards. Nipples created from the cutting and threading of approved pipe shall not be required to be identified.
