what is the leaking faucet in the middle of my DP

this was only our second trip in our new DP. There is a faucet below the undercarriage about right in the middle of the coach. Doesn't smell so I don't think it is any kind of oil. Only thing I can think of is it a drain for the moisture accumulated in the air compressor and if so do I need to do anything with it?

  • thanks for all the great help - I think you got it. It is on the bottom of the fresh water tank. Why would they have a separate drain for the fresh water tank? I would have thought the low point drains would cover it. I turned off the faucet and the water stopped.

    To my knowledge all FW tanks have a drain.


    Haven't heard of too many that require you to crawl under the RV. My low point fresh water drain is right inside my basement wet compartment.

    Low point will only drain the lines while a separate drain for the tank ensures you get every bit of water beyond what the pump will pull out. Also makes it easier to drain after sanitizing.

    Camping buddy's fifth wheel has what looks like a 1 1/2" drain valve. Dumps the tank in seconds. I have a 3/8" petcock to drain my tank. I open it and come back the next day to finish what I was doing.
