Is Your Insulated PEX Pipe Leaking? Here’s What You Need to Know

Insulated PEX pipes are becoming increasingly popular for underground applications as more and more people opt for energy-efficient plumbing and heating. Like any other plumbing system, however, there is always the potential for problems, particularly with leaks. To ensure your system is both efficient and long-lasting, you will want to know how to identify and fix these leaks. This article will look at some signs of leaking insulated PEX pipes, the cause of the problems, and solutions. 

Signs Your Insulated PEX Pipe May Be Leaking

It would quite be inconvenient to find a leak through an underground PEX pipe buried there. Nonetheless, a few signs may indicate that a leak is possibly present:

1. Isolating Possible Cause: Rising Water Bills: If, after some time, water bills begin to rise without apparent reason, then there is probably leakage through an underground insulated PEX piping system.
2. Water Accumulation: Always investigate any suspiciously damp patch or puddle in your house, especially around any pipes you might have installed. This usually could mean that the underground PEX pipe is leaking.
3. Diminished Water Pressure: A reduction in the water pressure of faucets or appliances could be a symptom of leakages in the piping.
4. Strange Sounds: If there are dripping or hissing sounds, it could be water leaking from the PEX pipes.
5. Visible Damage: Look for signs of wear and tear, such as cracks, around the insulated PEX pipe.

Common Causes of Leaks in Insulated PEX Pipes

Knowing the reasons behind leaks helps in dealing with similar annoyances in the future. Below are some of the most common causes of leaks in insulated PEX tubing: 

• Improper Installation: If the insulated tubing is poorly fixed, stress points may develop and rupture PEX tubing. Make sure all the fittings are tight and the connections are properly anchored. 
• Extreme Temperature Fluctuations: It is true that PEX withholds elongation under high tension and compressive forces. However, excessive changes in temperature will not spare PEX. The colder it becomes, the more the material shrinks, hence the tendency to develop leaks. 
• Ground Movement: The movement of soil either through settling or through freezing will exert force on the PEX prior to its fracture. This is particularly the case when backfilling is done poorly or when there is no proper support done.
• Chemical Exposure: As its name indicates, a cross-linked polymer can be degrading with exposure to some chemical components found in the earth. In any case, make sure that the PEX installation meets the requirements for the specific area, including its soil conditions.

How to Fix a Leak in Your Insulated PEX Pipe

When you believe your insulated PEX pipe has sprung a leak, do the following:

1. Identify the Leak: Make use of the properly aforementioned signs to help you confirm where the leak is located. This might even involve some excavation if the pipe lies in the ground.
2. Turn Off the Water Supply: Before trying to carry out any remedial works, first, the water flow must be shut off so as not to cause any further destruction.
3. Cut Out the Damaged Section: With the use of a PEX cutter, eliminate the leaking portion of the pipe.
4. Replace with New PEX: Prepare a section of PEX pipe that is long enough for the gap and use fittings to connect it back to the structure. Observe the fitting instructions as stated by the manufacturer.
5. Test the Repair: After installing the new piece, bring back the water supply and inspect the area of repair for any seepage.
6. Insulate Again: Provided your PEX pipe is installed below ground, fill it with insulation to mitigate against any thermal problems that may be experienced in the future.

Preventing Future Leaks

There are several things that you may do to prevent insulated underground PEX pipes from leaking. Consider the following preventive measures:

• Regular Inspections: Frequently inspect the entire plumbing system for the signs of any deterioration or malfunction.
• Proper Installation: Professional installation is therefore imperative so as to comply with the professional requirements.
• Adequate Insulation: For the underground laying of PEX pipes, high-grade insulated PEX pipes should be used in readiness for any temperature fluctuations.

You may ensure the functionality of your underground PEX water piping system by taking precautions, and as a result, help avoid expensive repairs in the future.

Conclusion

The importance of timely tackling the water leakages in insulated PEX pipes cannot be overemphasized. If you will always be on the lookout and aware of what to watch out for, it will be possible to mitigate any leaks.
