What Water to Use for a PEG Tube: A Guide to Safety and Flushing

5 min read

According to a study conducted at a multisite oncology institution, tap water was found to be a safe, effective, and cost-saving alternative to sterile water for flushing enteral feeding tubes for many patients. Understanding what water to use for a peg tube is crucial for preventing infections, avoiding blockages, and ensuring proper hydration.

Quick Summary

The type of water used for a PEG tube depends on the patient's immune status and health. Tap water is generally suitable for most healthy adults, while sterile or cooled boiled water is necessary for infants, immunocompromised individuals, or jejunostomy tube users. Flushing protocols with the correct water prevent tube blockages.

Key Points

  • Standard Water Choice: For healthy adults with a PEG tube ending in the stomach, freshly drawn tap water is generally safe and recommended for flushing.

  • Special Water Requirements: Immunocompromised patients, infants under one year, or those with jejunostomy tubes must use sterile or cooled boiled water to prevent infection.

  • Preventing Blockages: Regular and consistent flushing of the PEG tube with the correct water is essential to prevent blockages from formula and medications.

  • Proper Flushing Technique: Always use a gentle push-pause motion with an appropriate syringe (60ml) and lukewarm water, never applying excessive force.

  • Storage of Boiled Water: Cooled boiled water can be stored in a clean, covered container in the refrigerator for up to 24 hours before use.

  • Consult a Professional: The decision on the appropriate type and volume of water for your PEG tube should always be confirmed with your healthcare team, including your dietitian or nurse.

Understanding Water Options for Your PEG Tube

For anyone with a Percutaneous Endoscopic Gastrostomy (PEG) tube, knowing the correct type of water to use for flushing and medication administration is a fundamental part of daily care. The primary goal is to maintain the tube's patency and prevent the introduction of harmful bacteria, but the specific requirements can vary based on the patient's health status and the tube's location.

The Standard Choice: Safe Tap Water

For the majority of patients with a PEG tube that ends in the stomach (a gastrostomy tube) who are otherwise healthy, freshly drawn tap water is the standard and most widely recommended choice. Tap water in most municipal areas meets stringent safety regulations set by environmental protection agencies and health organizations. It is both cost-effective and readily available, making it a practical option for routine flushing after feeds and medications.

  • For Flushing: Use a 60ml enteral syringe to flush the PEG tube with 30-50ml of water. The volume can be adjusted based on a healthcare professional's advice. This should be done before and after every feed and medication to prevent buildup and blockages.
  • For Medication: Tap water is also suitable for dissolving crushed medications or diluting liquid medications, as long as the patient's condition allows.

When to Use Special Water: Sterilized or Cooled Boiled

Certain patient populations and specific circumstances require a higher level of water purity. This is especially important for those at greater risk of infection.

  • Immunocompromised Patients: Individuals undergoing chemotherapy, receiving immunosuppressant drugs, or with a weakened immune system should use sterile or cooled boiled water. This minimizes the risk of introducing bacteria that could cause a serious infection.
  • Infants and Children Under One: For infants and very young children, sterile or cooled boiled water is the safest option for tube flushes and feeding.
  • Jejunostomy Tubes: If the feeding tube is placed further into the small intestine (a jejunostomy tube), sterile or cooled boiled water is generally recommended, as the jejunum is less tolerant of bacterial loads than the stomach.

To prepare cooled boiled water, simply bring tap water to a rolling boil and let it cool before use. It can be stored in a clean, covered container in the refrigerator for up to 24 hours.

Comparison of Water Types for PEG Tube Use

Feature Tap Water Cooled Boiled Water Sterile Water Distilled Water
Suitability Healthy adults with gastrostomy tubes. Infants, immunocompromised patients, or those with jejunostomy tubes. Infants, immunocompromised patients, or filling balloon-retained tubes. Filling balloons on certain tubes, not for routine flushing.
Purity Filtered and treated by municipalities to meet drinking standards. Pathogens are killed by boiling, but minerals remain. Free from all microorganisms, commercially produced. Purified through distillation; free of chemicals.
Cost Most affordable option. Low cost, requires energy for boiling. High cost, sold as a medical product. Moderate cost, sold commercially.
Availability Accessible from any tap in areas with safe water. Can be prepared at home as needed. Purchased from medical suppliers or pharmacies. Easily found in most supermarkets.

Best Practices for Administering Water

Beyond selecting the right type of water, proper technique is essential for safe PEG tube management:

  1. Hand Hygiene: Always wash your hands thoroughly with soap and water before handling the PEG tube, syringe, or water.
  2. Proper Position: Ensure the patient is in a comfortable, upright position (at least 30-45 degrees) during and for at least 30 minutes after flushing or feeding to prevent reflux.
  3. Use the Correct Syringe: Use the specific enteral feeding syringe (often purple-coded) for administration. Using a smaller syringe can create excessive pressure and damage the tube.
  4. Flush Between Meds: When administering multiple medications, flush with a small amount of water between each one to prevent interactions and blockages.
  5. Use Gentle Force: When flushing, use a smooth, gentle push-pause technique. Never use excessive force, as this can damage or rupture the tube.
  6. Discard Unused Water: Cooled boiled water should be discarded after 24 hours to prevent bacterial growth.

Conclusion

Choosing what water to use for a peg tube is not a one-size-fits-all decision and depends heavily on a person's individual health circumstances. For many healthy adults, standard tap water is perfectly safe and effective for flushing and hydration, offering a convenient and affordable option. However, for vulnerable populations like infants or immunocompromised individuals, or those with jejunostomy tubes, the use of sterile or cooled boiled water is a critical safety measure to prevent infections. Always consult with your healthcare team to confirm the appropriate type of water for your specific needs, as their guidance is paramount for optimal PEG tube care and patient safety.
