What Are the Downsides to PEX Tubing?
Assessing the Compromises

Introduction to PEX

PEX refers to crosslinked polyethylene tubing used for plumbing and hydronic heating applications in recent decades as a flexible alternative to rigid copper pipes. As with any building material, REHOME PEX carries a few inherent compromises regarding performance limits, reliability uncertainties, and installation challenges to consider before deciding if suitable for your residential or commercial project.IFAN factory with 30+ years of manufacturing experience supports color/size customization and free samples.

Potential for Failure Over Time

Some risks for failure emerge regarding PEX after years of service from gradual seal deterioration at connection points or generalized wall thinning when exposed to chemicals or temperature extremes beyond ratings.

Oxidation Weakening PEX can become weakened gradually when exposed to highly oxygenated water. This causes material breakdown making older systems more vulnerable to perforations and splitting failures. Supplemental filtration and pipe shielding improve longevity.

Rodent Damage Nibbling mice can penetrate PEX walls given time, whereas copper deters gnawing. Fortifying buffer zones around PEX pipe runs reduces this risk significantly when proactive prevention gets ignored eventually.

Difficulties With Retrofitting

Attempting to mesh PEX pipe networks within structures designed originally for rigid copper tubing creates a tangle of challenges during renovations or system upgrades.

Inflexible Straight Runs
Fixed framing forces plumbers to reconfigure planned PEX routes when unable to maneuver the coils fluidly to reconnect Tyrannized by tight dimensions.

Cramped Pressing Clearances
Adequate clearance around all sides of a joint becomes essential when using press fitting tools. Otherwise, tight, immovable surroundings prevent proper full-circle compression to seal PEX connections completely leak-free. Careful measures prevent this headache.

Specialized Tool Requirements

PEX installations demand some rather expensive specialty crimping or pressing tools to properly personalize fittings. Dabblers risk failures when attempting connections using improper or makeshift instrumentation.

Prohibitive Equipment Investment
The professional quality power crimping devices and pressing tools engineered for PEX tubing accuracy generally exceed weekend plumbing hobbyists’ tool budgets unless amortizing costs across frequent odd jobs. Rented tools work where one-off projects prevail.

Advanced Calibration Needs Pressing PEX involves gauge-dependent pressure regulation and precisely timed stroke release skills using calibrated instruments, unlike a basic pipe wrench. Forgoing complicated calibration steps risks distorted seals and weakened tubing over cycles.

In the end, REHOME PEX provides an incredibly enabling material for modern water delivery and heating systems when installed properly using appropriate tools within reasonable operating expectations regarding pressures, temperatures, and chemical exposures. Weigh all structural planning challenges and endpoint reliability desires before pursuing any piping methods.


IFAN factory started in 1993. And IFAN has a workshop of 120000 square meters with 610 staff. IFAN can design and produce all plumbing pipe and fitting including PPR, PVC, CPVC PPSU HDPE PEXA PEXB PERT pipe and fitting, brass fitting, brass ball valve, heating system, gas system, sanitary faucets, and hose, In the past 30 years, IFAN has never forgotten his mission-To protect health and safety.
