Mystery water drip

lkc001

Have a couple questions after my most recent trip this last weekend-- will post them in separate posts-- 1st.  Was hooked up to shore power & water.  There are 4 drain hoses coming from the bottom of the trailer-- one white about 9 inches behind the tire drivers side which had a very slow drip while hooked up to water.  Another white drain@ 7 inches behind the first which drains water when either the hot water tank or fresh water drain lines are opened then a few inches behind the second white is I assume the alde fluid drain - it is black with a gray plug in the line.  Then there is another black drain line @ 16 inches in towards the center of the trailer that also drains water when the drain lines are opened.  What is the white drain directly behind the tire & why would it be dripping?  No leaks or water anywhere inside where all the plumbing lines are & only drips when on city water.  Yes I do have a pressure reducer on the city water faucet.  Ideas please?

It sounds like one of your water shut off valves isn’t fully closed. Check underneath the drivers side back cushion where the Alde lives. There are red and blue (hot and cold) line each going into the floor/drain. Check both valve handles to make sure it’s closed. Just the ones going to the drains though. Good luck!

Hi. We have a 2016 320S.

Ours is similar in layout, except...

The first drain back from the tire is red and drains the hot water line for winterizing. (Under constant pressure from city water, I'm guessing this valve is not fully closed, or it has some gunk in it. Open and close it a couple of times.)

The next one back is blue and drains the cold water line for winterizing.

The one just behind that is plugged and drains the Alde glycol.

The one 16 inches in from these is the Alde cold water drain (the yellow handle on the floor next to the Alde, it's hard to see the drain tube from the top side).

There is one more a couple of inches in from the blue cold water drain. It is larger. On the top side it has a rubber stopper with four holes. Two of these have clear lines from the Alde glycol reservoir. The third drains the Alde hot water pressure relief valve. The fourth drains the Alde glycol pressure relief valve.

Hope this is of use.

You aren't running the AC, are you?

@jkjenn I believe the AC drip tube is forward of the tire and towards center. At least that is where mine is.

I didn't know of the poster has the new setup and if the drip location had changed, but yes, on the T@bs with the window style AC, it is ahead of the tire.

@jkjenn No I wasn't using the a/c.  According to the pic from @MuttonChops-- thanks!  It must be coming from the hot water drain line-- I'll be checking out that shut off valve next-- thank you all for your info😀
