Common Causes Of Dripping
Leaks in Navien tankless water heaters often stem from loose connections, faulty valves, or mineral buildup. Regular maintenance can help prevent these common issues.
Loose Connections
Drips often come from loose connections. Check all pipes and fittings. Tighten them if needed. Even small gaps can cause leaks. Always use the right tools. Incorrect tightening can damage parts.
Faulty Valves
Faulty valves are another cause of drips. Valves control water flow. If they break, they can leak. Inspect each valve carefully. Replace any that seem worn out. New valves prevent future leaks.
Condensation Issues
Condensation can also cause dripping. This happens when warm air meets cold surfaces. It creates water droplets. Insulating pipes can help. This stops condensation from forming. Make sure the heater has proper ventilation.

Identifying The Source Of The Leak
Start by turning off the heater. Remove the cover to see inside. Look for visible signs of water. Check around the heat exchanger and connections. Any water spots or corrosion can indicate a leak.
Examine all the pipes connected to the heater. Make sure to look at the inlet and outlet pipes. Feel for any wet spots or drips. Tighten any loose connections with a wrench. Replace any damaged piping.
Inspect the pressure relief valve. This valve can drip if pressure is too high. Check for any cracks or corrosion. Make sure it is properly sealed. Look at the drain valve as well. Ensure it is not leaking.
Tools Needed For Quick Fixes
A screwdriver is very useful for many tasks. Wrenches help in tightening and loosening bolts. Pliers can grip and twist parts easily. Tape is great for temporary fixes. Buckets are important to catch water.
A pipe cutter is essential for cutting pipes neatly. Teflon tape helps to seal pipe threads. Pressure gauge checks the pressure levels. Digital multimeter is used to test electrical connections. Pipe wrench is perfect for large pipe fittings.

Fixing Loose Connections
Loose connections can cause water to drip. First, turn off the water supply. Use a wrench to tighten any loose nuts. Make sure not to over-tighten. Over-tightening can damage the connections. Check all the fittings carefully. Ensure all are snug and secure.
Sealants can help stop leaks. Apply thread sealant tape to the threads. Wrap the tape around the threads 2-3 times. Press down to make sure it sticks. For extra protection, use a pipe joint compound. Apply it to the threads before screwing them together. This creates a strong, waterproof seal.
Replacing Faulty Valves
Choose a valve that fits your water heater. Make sure it is the correct size. Look for valves made from strong materials. Brass and stainless steel are good choices. Check the valve’s pressure rating. It must match your heater’s requirements. Read reviews to find reliable brands. Good brands last longer and work better.
Turn off the water supply first. Drain the water from the heater. Use a wrench to remove the old valve. Be careful not to damage any pipes. Install the new valve in the same place. Tighten it with the wrench. Turn the water supply back on. Check for leaks around the new valve. Tighten more if needed.
Dealing With Condensation
Condensation happens when pipes are cold. This can lead to dripping. To fix this, cover your pipes with insulation. Pipe insulation keeps the pipes warm. This stops condensation from forming. You can buy pipe insulation at most hardware stores. It is easy to install. Just wrap it around the pipes. Make sure there are no gaps. Gaps let cold air in. Cold air causes condensation. Insulating pipes helps your heater work better.
The temperature setting can cause condensation. Set the heater to a moderate temperature. This reduces the chance of dripping. Very hot or very cold settings can cause problems. Check the manual for the best temperature. Adjust the settings as needed. This keeps your heater working well. It also helps prevent dripping.
Preventative Maintenance Tips
Inspect the heater every six months. Look for leaks and corrosion. Clean the air intake and exhaust vent. Check the water filter. Make sure it is clean. Replace if dirty. Look for error codes on the display. Call a professional for serious issues.
Ensure the heater is installed by a certified technician. Follow the manufacturer’s guidelines. Use the right materials and tools. Check the gas supply and water pressure. Make sure they meet the requirements. Secure the venting system. Make sure it is not blocked.
