Water in the air system can cause air valves to fail & leak. Your coach has 10 or 11 air tanks that need to be drained regularly. I drain mine when I lubricate the coach at 5,000 miles. You may or may not have an air tank in compartment R-1. You do have a wet tank in the front of the right wheelwell. You also have nine more air tanks under the coach. Also the desiccant filter needs to be changed regularly. I do mine annually.
