Yes RV Water Heaters can develop leaks and yes they can be replaced and depending on the cause of the leak even repaired.
The first thing you need to do is make sure that the leak is actually coming from the water heater and not a loose connection or cracked water line under the sink. Unless you are comfortable working with the plumbing in your RV you may want to take your Travel Trailer in and have a Certified RV Technician take a look at the water system on your RV and determine the exact cause of the leak.
Whether your water heater is replaced or not you need to be aware that there is some routine maintenance that you can perform to extend the life of your water heater. Take a look at the video below by RV Expert Mark Polk from RV Education 101 to learn about the maintenance that should be performed.
If you have done the routine maintenance and still determine that the water heater is leaking, you may decide to replace the water heater yourself. Before you tackle this project you may want to take a look at the video below that will walk you through the process of replacing a conventional RV Hot Water Heater.
Another option you should look at if you have to replace your water heater is replacing it with a Tankless RV Water Heater. The advantage of a tankless RV Water Heater is that it will provide a constant supply of hot water in your RV. For even more information on RV Tankless Hot Water Heaters you may want to take a look at the video below by RV Expert Mark Polk from RV Education 101.
