Why Is My Water Heater Leaking?
There are several reasons why your water heater might be leaking. Some leaks are minor and easy to fix, while others indicate serious internal damage.
Here are the most common causes of a leaking water heater:
1. Loose or Faulty Drain Valve
The drain valve is used to flush sediment buildup from the tank. If itβs loose or damaged, it can leak water slowly.
π§ How to Fix It:
β’ Check if the drain valve is fully closed.
β’ If the leak persists, tighten the valve with a wrench.
β’ If the leak continues, you may need a replacement drain valve.

2. Corroded or Damaged Tank
Over time, rust and corrosion can develop inside the tank, causing weak spots that lead to leaks.
π§ How to Fix It:
β’ If the tank itself is leaking, it cannot be repaired and will need a replacement.
β’ To prevent corrosion, flush your water heater annually to remove sediment.
β’ Consider installing a tankless water heater, which eliminates the risk of tank corrosion.

3. High Water Pressure
Excessively high water pressure can put stress on your water heater, causing leaks.
π§ How to Fix It:
β’ Check your homeβs water pressure regulator (it should be set between 40β60 psi).
β’ If the pressure is too high, you may need to install a pressure-reducing valve (PRV).
β’ If you suspect high water pressure, contact us for a water pressure inspection.
4. Faulty Temperature and Pressure Relief (T&P) Valve
The T&P valve is a safety feature that releases excess pressure from the tank. If it malfunctions, water may leak from the valve.
π§ How to Fix It:
β’ First, check if the valve is loose and tighten it if necessary.
β’ If the leak continues, the valve may need to be replaced.
β’ If pressure buildup is the issue, we can install an emergency shut-off valve for added safety.
5. Worn-Out Inlet and Outlet Connections
The cold water inlet and hot water outlet connections can become loose or worn over time, leading to leaks.
π§ How to Fix It:
β’ Inspect the connections at the top of your water heater.
β’ Tighten any loose fittings with a wrench.
β’ If the leak persists, you may need new fittings or pipe replacements.
How to Prevent Future Water Heater Leaks
To avoid costly repairs, follow these preventative maintenance tips:
β Flush your water heater annually to remove sediment buildup.
β Check the anode rod every 3β5 years to prevent corrosion.
β Inspect the T&P valve regularly to ensure itβs functioning properly.
β Monitor water pressure and install a PRV if needed.
β Consider switching to a tankless water heater, which has a longer lifespan and requires less maintenance.
