Reasons water heaters leak from the bottom.

Water leaking from the bottom of the heater can indicate more serious issues. Here are the main causes:

1. A leak from the drain valve

  • Cause: The drain valve, located near the bottom of the tank, can become loose or faulty.
  • Repair: Tighten the valve carefully with a wrench. If water continues to leak, the drain valve may need to be replaced. If you need help, call us for assistance.

2. The internal tank is leaking

  • Cause: Over time, sediment buildup or corrosion can weaken the inside of the tank, causing it to crack and leak.
  • Repair: Unfortunately, an internal tank leak means the water heater will need to be replaced. If your water heater is over 8-10 years old, it’s likely time for a new system. Contact us for advice on water heater replacement.

3. Condensation

  • Cause: In humid conditions or with high-efficiency water heaters, condensation can form and appear like a leak.
  • Repair: Wipe the tank dry and observe whether the water reappears. If it’s condensation, there’s no need for repairs. If it’s an actual leak, call us for assistance.

4. A faulty pressure relief valve

  • Cause: As with leaks at the top, a malfunctioning temperature and relief valve (TPR valve) can leak excess water and cause pooling at the bottom.
  • Repair: Replace the faulty TRP valve and ensure the pressure in your system is properly regulated. Contact us for TPR valve repair and replacement.

How to prevent water heater leaks.

Below are a few tips to keep your hot water heater in good working order and avoid leaks.

  • Regular maintenance: Flush your water heater annually to remove sediment buildup.
  • Check the anode rod: Inspect and replace the anode rod every 3-5 years.
  • Monitor pressure: Ensure your water pressure doesn’t exceed the recommended levels.
  • Book a regular water heater service: Did you know that your water heater should be serviced every 5 years?

Regular water heater service prevents problems, including leaks.

Getting your hot water system serviced by Cheapa Hot Water every 5 years will ensure it is in good working order and running efficiently.  We can replace parts that may be showing signs of imminent failure, preventing unexpected and catastrophic breakdown, whilst increasing the life expectency of the appliance. It’s a small price to pay for peace of mind and trouble free hot water usage.

To ensure you don’t void your warranty, any repair or service of your hot water heater should be undertaken by an experienced and licensed hot water plumbing technician.

Servicing your hot water system typically takes between 30 – 45 minutes.
