Identifying the Source of the Leak

Okay, so your IRV water heater is leaking inside. Now what? The first step is to pinpoint exactly where the leak is coming from. This might seem obvious, but it's crucial for choosing the right repair strategy. Grab a flashlight and get ready to do some detective work. Carefully inspect the entire water heater, paying close attention to these areas:

• The Tank: This is the big one. Look for any signs of rust, corrosion, or cracks on the tank itself. These can indicate a major issue, and in some cases, the tank might need to be replaced. A rusted tank often means the internal lining has failed, and water is seeping through. Look for water stains, drips, or puddles around the base of the tank. Also, check the seams and welds for any signs of leakage.
• The Connections: Examine all the water line connections, including the inlet and outlet pipes, as well as the connections to the pressure relief valve and drain valve. Make sure all fittings are tight and secure. Look for any drips, leaks, or signs of water damage around these connections. Sometimes, a simple loose fitting is the culprit, and tightening it can solve the problem. Corrosion or mineral buildup around these connections could also indicate a leak.
• The Pressure Relief Valve (PRV): This valve is designed to release pressure if it gets too high, preventing the tank from exploding. It's usually located on the top or side of the water heater. Check for any water dripping or spraying from the valve. A leaking PRV could be due to a faulty valve, excessive water pressure, or a buildup of sediment.
• The Drain Valve: This valve is located at the bottom of the water heater and is used to drain the tank. Check for any leaks around the valve itself or where it connects to the tank. Sometimes, a worn-out or damaged drain valve can cause a leak.
• The Anode Rod: If you're comfortable with it, remove the anode rod (usually located on top of the water heater) and inspect it. This rod helps protect the tank from corrosion. If the anode rod is severely corroded or depleted, it could be a sign that the tank is starting to corrode as well, potentially leading to a leak. But, It's less likely to cause an immediate leak but can be a sign of future problems.

Take your time and thoroughly inspect each of these areas. Sometimes, the leak might be intermittent, only appearing when the water heater is heating water. If you can't find the leak right away, try running the water heater for a while and then checking again. This systematic approach will help you narrow down the source of the leak and determine the best course of action. If you have narrowed down where the leak is from you can move to the next step which is diagnosing the problem.

Common Causes of Leaks & How to Troubleshoot

Now that you've identified where the leak is coming from with your IRV water heater leaking inside, let's dive into the most common causes and how to troubleshoot them. Remember, safety first! Always disconnect power and water before starting any repairs. Here’s a breakdown of the most frequent culprits:

• Loose Fittings and Connections: This is often the easiest and most straightforward fix. Over time, vibrations from driving and normal use can loosen the water line connections. If you find a leak around the inlet or outlet pipes, or any other connections, try tightening the fittings with a wrench. Be careful not to overtighten, as this could damage the fittings. If tightening doesn't stop the leak, you might need to replace the fittings or the water lines. Check for cracks or damage to the lines themselves. Ensure that the water heater is properly supported and secured to prevent excessive vibration.
• Faulty Pressure Relief Valve (PRV): As mentioned earlier, the PRV is designed to release excess pressure. If it's leaking, it could be due to a faulty valve, excessive water pressure, or a buildup of sediment. Try lifting the lever on the PRV to flush out any debris that might be lodged inside. If that doesn't work, you'll likely need to replace the PRV. It's a relatively inexpensive part and easy to install. To test the water pressure, you can use a water pressure gauge to check if the water pressure in your RV exceeds the water heater's pressure rating. If it does, you may need a pressure regulator on your water supply to reduce the pressure. Too high pressure could have damaged the valve in the first place.
• Worn or Damaged Drain Valve: The drain valve can leak due to wear and tear, mineral buildup, or damage. Inspect the valve for any signs of leaks. Try tightening the valve or replacing the valve's seal. If the leak persists, you'll need to replace the entire drain valve. Make sure to use the correct type of valve designed for your water heater model. When replacing, use Teflon tape on the threads to ensure a watertight seal.
• Corroded or Damaged Tank: This is the most serious issue. If the tank itself is leaking, it usually means the internal lining has failed, and the tank is corroding. Look for signs of rust, corrosion, or cracks on the tank. Unfortunately, if the tank is leaking, the best solution is usually to replace the entire water heater. This is often an expensive repair, so it's important to catch the problem early by regularly inspecting your water heater. It's the most costly repair, it is worth the inspection time you spent.
• Failed Anode Rod: While not a direct cause of leaks, a depleted or corroded anode rod can lead to tank corrosion, which can eventually cause a leak. Regularly inspect and replace the anode rod (usually annually) to protect your tank. If you find significant corrosion on the anode rod, it's a good idea to inspect the tank for any signs of corrosion as well. This will help extend the life of your water heater. This is one thing you can do to prevent costly repairs.

By carefully inspecting these components, you should be able to identify the most common causes and implement some simple troubleshooting steps. If you are not comfortable or able to do these steps you can always consult a professional.
