Nowadays, PEX pipes - especially ASTM F1960 ■■■■■■■■ - are offered in larger sizes of 2-1 / 2 “and 3” which allow for greater use and flow in commercial plumbing and plumbing work. Applications.
PEX diameter PEX pipes have a diameter of 3/8 “to 1” for housing. For adequate water flow, it is a good idea to install 1/2 “or 3/4” PEX for the main pipes. The standard when replacing old water pipes with PEX is to use the same size.
There are three different types of PEX pipes: PEXa, PEXb and PEXc. Uponor produces PEXa pipes, which are considered the superior type of PEX in the industry because crosslinking occurs during the manufacturing process when the polyethylene is in an amorphous state (above the crystalline melting point).
Church, CEO of the Plastic Pipe and ■■■■■■■■ Association. Uponor Wirsbo said PEX pipes were introduced in California in 1990 and the product helps solve problems in areas with aggressive soil conditions that copper pipes cannot.
In most cases, the main road pipe to your home will be 3/4 or 1 inch in diameter, the utility branches will use 3/4 diameter pipes, and the individual component pipes will be 1/2 in diameter. . Remember that for every path that extends over the water supply, the water pressure will drop by half a kilo per square inch.
The pex / plastic pipes have a higher capacity than copper. However, the inside diameter (inside diameter) of the Pex ■■■■■■■ is smaller than that of a pipe of the same size, so the flow of water is substantially prevented.
Increasing the pipe diameter does not change the static pressure (the pressure when no water is flowing). However, if you open a faucet, the water pressure on that faucet will drop slightly, and because a larger hose offers less resistance, the water pressure on the larger hose will drop less.
PEX pipe sizes are indicated by CTS (copper pipe size), not OD (outside diameter) or ID (inside diameter). The outside diameter of PEX, copper and CPVC (CTS) pipes of the same size is the same. For this reason, all these tubes can be used with plug connections.
Color code: red PEX pipes can be used for hot water supply, blue PEX pipes for cold water supply and white PEX pipes for hot or cold water supply. These colors are for your convenience only. The plumbing code does not require the color of the hose to match the type of water supply.

The internal drinking water pipe is made from a plastic called cross-linked polyethylene (PEX). There is no health risk with drinking water from PEX pipes. Some types of PEX pipes can cause a long-lasting unwanted taste and smell if water remains in the pipe over time.
Disadvantages of PEX Installations
Pressing and compression produce equally reliable seals that, when done correctly, will not leak. Stainless steel locking rings are more corrosion resistant than copper shrink rings, which can be a great advantage when laying directly into the ground. PEX clamps are often also easier to remove.
PEX does not degrade like copper, freezer pipes with a higher PSI value will continue to break, but PEX can handle more ice water than copper. PEX pipes are much more frost resistant than copper or rigid plastic pipes. PEX is cheaper / easier to install and usually not as many connections are needed.
Yes, they are not intended for use with gas and no hose clamps will work. You don’t even get full compression with hose clamps, so it leaks.
Typically, SharkBite ■■■■■■■■ only leak for one of the following reasons: The hose was not primed properly prior to installation. The tube is not positioned correctly. The tube has scratches or dirt on the outside, which prevents the Oring from sealing.
PEX cannot be connected directly to a water heater. First, stretch an 18-inch hose from the water heater and connect the PEX power supply to the hose.
