A leak in your RV bathroom sink can be a frustrating and potentially costly issue. When the leak is coming from the bottom of the hot water faucet, there are a few common causes that you should be aware of. By understanding these causes, you can troubleshoot the issue and determine the best course of action for repair. One of the most common causes of a hot water leak in an RV bathroom sink is a worn or damaged O-ring. This small rubber ring is responsible for creating a watertight seal between the faucet and the sink. Over time, the O-ring can become brittle or worn, causing water to leak out from the bottom of the faucet. Another potential cause of a hot water leak is a cracked or damaged cartridge. The cartridge is a small valve that controls the flow of hot water in the faucet. If it becomes damaged, water can leak out of the bottom of the faucet. This is often accompanied by a decrease in hot water pressure. Finally, a loose or faulty connection between the hot water supply line and the bottom of the faucet can also cause leaks. This can occur if the connection was not properly tightened during installation or if it has become loose over time. In some cases, the connection may also be damaged, leading to leaks. Common Causes of RV Bathroom Sink Hot Water Leaking from Bottom
Depending on the cause of the leak, there are a few different ways to repair an RV sink hot water leak. If the issue is a worn or damaged O-ring, the easiest solution is to simply replace the O-ring. This can be done by turning off the hot water supply and unscrewing the faucet from the sink. From there, you can access the O-ring and replace it with a new one. If the issue is a damaged cartridge, it may need to be replaced. This can be a more involved repair, as it may require disassembling the faucet and replacing the entire cartridge. It's important to ensure you have the correct replacement cartridge for your specific faucet model. In the case of a loose or faulty connection, it may simply need to be tightened or replaced. Again, it's important to ensure you have the correct replacement part for your faucet. If the connection is damaged, it will need to be replaced entirely. How to Repair an RV Sink Hot Water Leak

If it does, the issue is likely with the hot water supply line or connection. If the leak continues even with the hot water supply turned off, the issue is likely with the faucet itself.
