Cast iron pipe is a pipe which has had historic use as a pressure pipe for transmission of water, gas and sewage, and as a water drainage pipe during the 19th and 20th centuries. It comprises predominantly a gray cast iron tube and was frequently used uncoated, although later coatings and linings reduced corrosion and improve hydraulics.
Residential plumbing pipes come in many varieties and types of metal and plastic pipes. Each pipe has their pros and cons and particular special usages in your home. Understanding your options is the first step when considering a large repiping project for your home.
Place the copper fitting on the pipe only after it is thoroughly cleaned and coated with soldering paste. When the fitting is firmly in place, rotate both the pipe and the fitting several times to spread the flux evenly. A propane torch is the tool we’ll use to sweat copper pipe.
A cross-linked polyethylene (PEX) pipe Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links. It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, and insulation for high tension (high voltage) electrical cables.
This product does not comply with the "Safe Drinking Water Act," which requires that products meet low-lead standards in order to be used in systems providing water for human consumption (drinking or cooking). This item is for non-potable (non-human consumption) water applications only.
A street elbow (sometimes called a street ell or service ell) is a type of plumbing or piping fitting intended to join a piece of pipe and another fitting at an angle. The difference between a street elbow and a regular elbow is the nature of the connections on either end.
There are two basic types of copper pipe or tubing: rigid and flexible. Rigid pipe, usually installed in new homes, makes a neater installation, but it is much more difficult to install than soft, flexible copper pipe. Flexible copper pipe is best for repair work since it can be run around obstacles without connections or cuts.
Galvanized steel water distribution pipes were used almost exclusively in Minnesota homes up until about 1950, when copper tubing began to replace galvanized pipes. Copper gradually replaced galvanized piping during the 1950’s, and was about the only thing used for water pipes in homes by 1960.
Knowing the history of this piping and what age, thousands of gallons of water does to galvanized pipe, we removed the nipple that was 95% obstructed and installed a new multi-turn shutoff valve directly onto the 3/8" brass riser that protrudes through the floor.
Water hammer can also occur when water pressure is too high. Installing water pressure regulators can solve water hammer issues due to water pressure. Whenever you have the opportunity, consider installing a pressure reducer valve at the location where the main water supply enters the home instead of installing multiple air chambers.
Copper pipes are used normally in the construction industry for the supply of water and as a refrigerant line in HVAC systems. However, there are many different types of copper piping with particular uses depending on how it is classified and where it will be installed.
Brass short rod forged flare nuts are used Brass short rod forged flare nuts are used for higher pressure applications with aluminum copper brass and welded steel tubing or fittings. They are recommended for oil LP natural gas and fuel lines (not for use with polybutylene or soft plastic tubing).
