More About 1" PEX tubing with Oxygen Barrier
1" PEX is most commonly used for running supply and return lines to an outdoor wood boiler or furnace. It is well suited for direct underground burial in a trench, with proper thermal insulation provided.
1" PEX is a cost-effective alternative to copper pipes, used for hot water supply lines in radiant manifold, boiler and storage tank installations.
It is also suitable for snow melting systems in large-scale commercial applications, including parking lots, outdoor recreational areas, etc.
Frequently Asked Questions
Q: What is the recommended trench depth to bury PEX pipe?
A: The minimal trench depth is determined by ground freezing level in your area. Tubing must always be buried below this level to prevent the water inside from freezing when system is off. The colder the climate, the deeper the trench should be.
Q: What’s the best connection method for 1" PEX?
A: The pipe is compatible with crimp, clamp (also called “cinch”), compression, press and quick-connect methods. We generally recommend the crimp method as the most time-tested and proven.
Q: Is 1" PEX much stiffer compared to 1/2" and 3/4"?
A: 1" pipe is thick and indeed can be somewhat stiff when compared to smaller PEX sizes. The brand and type does not make much of a difference. To remedy, place the coil in a warm place prior to the installation or (if available), place it in a tub filled with hot water - this will make the pipe noticeably more flexible.
