The plumbing industry is constantly growing with new ideas and ways to get the job done. Over the years many pipes have been used for plumbing (abs, pvc, copper, etc.) Now plastic or (PEX) piping can be used in almost all plumbing applications.
PEX plumbing pipe is increasingly growing in popularity as an alternative to copper pipes due to it’s higher flexibility, ease of installation and cheaper cost.
PEX tubing is a cross-linked polyethylene pipe that is fairly new to the plumbing market. It is a single-layer pipe with smooth inner surface and matte exterior and comes in red and blue colors for easier distinction between hot and cold water lines. (Also in black and white.) Often assumed to be weaker then metal pipe, PEX will hold up just as long if not longer.
1/2″, 3/4″ and 1″ PEX pipes sizes are the most common for residential and small commercial installations
1/2″ PEX is the most common of all sizes and is typically used in conjunction with PEX plumbing manifolds to carry hot or cold water to plumbing fixtures. This size is also the most cost-effective and one of the most flexible tubing sizes.
3/4″ PEX is generally used for main water distribution lines in small to medium sized residential homes. Usually, it carries the supply of water from the water heater to the PEX manifold. Due to it’s larger water carrying capacity, 3/4″ PEX can also be used for plumbing fixtures which require high flow rates. These include shower jets, jacuzzi tubs and similar.
1″ PEX is typically used for water mains in medium to larger size residential homes.
3/8″ PEX pipe can be used for plumbing fixtures with normal or less than normal water flow requirements.
PEX does not get pinhole leaks as easy as copper can and there are usually less connections needed when installing PEX. Since it is also cheaper then copper, then the customer will save more money.
Diamondback Plumbing has been using PEX on many installations since it has came to the market. We have seen first hand the quality of the tubing and have no problems installing into any home or project.
