The Rise of PEX in Modern Construction
In the world of professional plumbing and radiant heating, the PEX pipe has
become the preferred choice for its flexibility, durability, and
cost-effectiveness. However, "easier to install" does not mean "foolproof." Even
the highest quality pipes, like those manufactured by Ritable, can fail if basic
installation principles are ignored.
To ensure your system lasts the promised 50+ years, avoid these
five common installation blunders.
1. Using the Wrong Tools for the Job
One of the most frequent errors is using a crimping tool on an expansion
system, or vice versa. Ritable PEX-A pipes are specifically designed for
high-performance cold expansion connections.
The Fix: Always use certified expansion tools and rings. Using a mismatched
tool can create a weak seal that might hold during a pressure test but fail
months later under thermal stress. Check our Plumbing Fittings page for
compatible connection solutions.
2. Ignoring Thermal Expansion and Contraction
Unlike copper, PEX expands and contracts significantly as water temperature
changes. A common mistake is installing the pipe too tightly—like a guitar
string. This puts immense stress on the fittings every time the hot water is
turned on.
The Fix: Always leave a little "slack" or create a small loop in long runs.
This allows the pipe to move naturally without pulling at the joints.
3. Improperly Fixing Kinks
Kinks happen, especially in tight renovations. However, how you handle a
kink determines the life of the pipe. If you are using PEX-B and it kinks, you
must cut it out. Many installers try to "straighten" it, which creates a
permanent weak spot.
The Ritable Advantage: Our PE-Xa Series Pipe features unique "thermal
memory." If a Ritable PEX-A pipe kinks, you can carefully use a heat gun to
return the pipe to its original shape and strength. This saves time and material
costs.
4. Excessive Exposure to UV Light
PEX is a powerhouse indoors, but it has a "kryptonite": sunlight. UV rays
break down the molecular bonds in polyethylene, making the pipe brittle and
prone to bursting. Many installers leave coils at the job site uncovered for
weeks.
The Fix: Keep your Ritable pipes in their protective UV-resistant packaging
until the moment of installation. Never install PEX in outdoor locations where
it is exposed to direct sunlight.
5. Bending the Pipe Too Sharply
While PEX is flexible, it has a "minimum bend radius." Forcing the pipe
into a turn that is too sharp puts constant tension on one side of the pipe
wall, which can lead to stress fractures over time.
The Fix: Use bend supports or "drop-ear" elbows for 90-degree turns. As a
rule of thumb, the bend radius should be at least 5 to 8 times the outside
diameter of the pipe.
Conclusion: Choose Quality, Choose Ritable
Avoiding these mistakes starts with choosing the right material. Ritable’s
PEX-A pipes provide the flexibility and professional-grade reliability needed to
overcome common site challenges. Whether you are a DIY enthusiast or a
professional contractor, following these guidelines will ensure your underfloor
heating system or plumbing network remains leak-free for decades.
