tzscales Report post Posted April 1, 2018 Greetings!! In the process of draining my rear air tank I noticed a leaking drain valve which is located in the engine compartment. It has an air line connected to it that leads to the air tank. This was confirmed by spraying a soapy solution on the valve. Is this as simple as removing and replacing with a new one? I know that I will need to drain the tank first and will not need to crawl under the coach. Is is a replacement easily attainable? Thanks for any feedback.
