Is there flexible PEX pipe?
PEX is the most flexible plumbing pipe available. It can be bent around most corners without a coupling or fitting. For example, 3/8” pipe may be bent to a 4” radius and 1/2” pipe to a 5” radius. Most plumbing leaks and system failures occur at joints in fittings.
Can you stretch PEX?
Stretching the piping requires a special tool – hand-powered or cordless electric – with an expanding cone tip. As you crank the tool, the cone expands the plastic. Some plumbers install PEX piping like traditional water supply lines. If you do this, be aware of water pressure and friction losses.
Why do you need a PEX expander?
PEX A uses an expansion-style fitting. These fittings are much larger in diameter the PEX B fittings, and require an expansion tool. Because PEX A is expandable, the material’s memory will ensure that it will shrink back to its normal size, tightening snugly around the fitting.
Why do my PEX fittings leak?
When water flows through your PEX pipes, the zinc in the fittings can seep out of the fittings, causing a white residue to build up inside the pipe, constricting water flow. It also causes fittings to crack or break, leaking water within your walls or underneath your house.
Are brass PEX fittings better than plastic?
The basic fact is that plastic fittings is better and effective, unlike the brass PEX fitting. Due to the problem earlier caused by polybutylene (PEX predecessors) plastic PEX fitting have been recommended. It is true that in areas where water is less acidic, brass fitting is better.
Can you bury brass PEX fittings?
PEX tubing is approved for direct burial outdoors, a practice most often necessary when running a water supply line to a house. PEX, since it can expand, resists freezing more effectively than rigid pipe, but PEX can still burst if water freezes in a line.
