In particular, two pipe materials dominate retrofits and new installations while one newer material is making a name for itself. As you may know, copper is viewed as the “gold standard,” but PVC and its cousin CPVC are widely used and safe. Meanwhile, PEX is flexible, and widely used in retrofits and new construction alike.

Rigid pipe made of copper
If you look at your pipes and see steel or another type of metal other than copper, there’s a good chance those pipes have been in place for decades. ABS is also lightweight, easy to install, inexpensive, and resistant to cold temperatures, making it useful for underground outdoor use. One drawback to remember regarding PEX pipe is that you cannot use it for outdoor jobs because the sun’s UV rays can damage the material. Homeowners might also notice that their drinking water tastes slightly different after switching to PEX, especially in the beginning. This product is a preferred pipe for many contractors because it works with several different connection methods. As a result, it’s compatible with many of the tools on the market.
Flexible pipe, often called flexi for short, is flexible tubing typically made of stainless steel. It's commonly used for final piping connections to appliances, such as water heaters, toilets, and sinks. London fire brigade said the burst water main had led to flooding of up to half a metre in depth. People have been forced to evacuate from their homes because of a burst water main in a north London street. For any of your faucets served by exposed pipes, letting the cold water drip from the faucet can help prevent freezing.

'Shift water rescue crews used boats to move around 20 people to upper floors of properties. Without any pipe disruption, the water is safe to using for drinking, cooking, bathing and other purposes, officials say. "As the mild air meets the cold air currently in situ over the UK there will be a transient spell of snow, potentially to low levels, especially in the north.

Different Ways to Thaw Enclosed Pipes
It is an excellent choice for exterior underground use and has a high tolerance for heat. It must be properly installed and supported and can only be used on the exterior of the home for non-potable water. Because it is thinner and highly flexible, it can be prone to breakage more so than other options. Generally speaking, the main pipeline from the street to your home is either ¾ or 1 inch in diameter.
PVC pipes contain a smooth inner lining as well, which protects against sediment buildup and makes them more resistant to blockages. This inexpensive polyvinyl chloride piping is used for drain or vent lines. It is lighter to work with than the galvanized steel pipe used before it gained popularity. It is easy to cut and install using glue solvents, which means that you’ll have to cut and replace those sections if repairs are needed later. It must be well supported with all fittings installed accurately and tested. Diameters are marked on the outer surface of the pipe for ease of selection.
Both kinds of copper pipe can be joined with permanently soldered fittings or flare/compression fittings that can be disassembled. They are used in water distribution networks where the water is treated before distribution and chlorinated to prevent contamination. PVC usually gets its watertight joints from primer and glue, which enable design, retrofit and installation freedom. So it can be a smart choice for a retrofit job where space is limited.
These are located in exterior walls, unheated garages, the floor cavities above unheated crawl spaces, and the like. Generally speaking, it's not necessary to insulate pipes that run through interior walls or in basements that are heated. When preventing freezing is the goal, insulate both the hot- and cold-water pipes. Hot water pipes can also freeze unless water is actively running through them. Galvanized or zinc-coated steel pipes were used in the early 20th century to replace cast-iron and lead in cold-water plumbing. However, galvanized pipes rust from the inside out, building up layers of plaque that cause water pressure issues.
Supply pipes are ¾ inch in diameter and individual components are ½ inch in diameter. You can get a clue about the type of pipes used in your plumbing by looking at the year your home was built. The best way to determine the type is by having a peek at the pipes. All pipes used for all utilities at homes combined are called Home pipes. These pipes are required to carry water, waste, conduits for electrical & data wiring, air conditioning drains and piped gas. The material is lightweight, affordable, and its flexibility helps resist breaks and tears, which explains why it’s widely used in American homes.
When you see PEX as part of your plumbing system, you’ll notice that it’s often color-coded with the blue pipe carrying cold water and the red tube holding hot water. However, there are white PEX pipes, too, which can have either hot or cold water. These pipes are usually 1/2-inch in diameter, although some homes have 3/4-inch copper pipes.
Generally, water supply pipes within walls are considered to be insulated enough that they don’t need extra insulation. Continue to wrap the pipes with insulation until you reach the point where the water supply lines enter the floor above. Fiberglass pipe insulation should be used in high heat areas such as near the water heater or furnace. It can also be used in areas where the pipe makes many complex turns, since fiberglass pipe insulation is easy to wrap around bends. PEX is the go-to choice for water supply lines in newer homes or when homeowners replace their existing water lines because of its low cost and ease of use.
This type of pipe is affordable and available in a number of different fittings and sizes. It’s also a great choice for most warm and cold water applications. Though this kind of plumbing pipe is easy to install, it can warp when exposed to direct sunlight. ABS pipes are also noisier than other types of plumbing pipes, causing disturbances among some homeowners.
