Question on low point drain ports

[vaarta]

Hello, first time poster and apologies if this is the wrong location for my question (I own a 2017 Apex Nano 185BH).

I noticed that there were two low point drain ports. I could recognize one as the drain port for the fresh water tank since it was right underneath it.

The second one, I am having difficulty with. It is located underneath the general sink area. Any idea what this one is for?

Thanks!

There are usually two low point drains, one red for hot and one blue for cold. They can either have caps on the ends or some have a valve on the end. SOME have the valve inside the trailer and just a hose hanging out underneath. For an Apex Nano, I'd bet on just plugs. You can see my plugs in this pic (not very well, though):



In addition there should be a FW tank overflow, it could be any color, but is usually white.

Then you may or may not have a FW drain hose. Most FW drains are either just a plug or have a valve installed similar to this one, although there are some other styles:



My FW tank had the plug, located right between the axles. I installed an elbow and some PEX and brought it out to a valve like above. You can see it in the first pic; I painted it black and it pretty much disappears into the rest of the plumbing underneath.

What was your source for the above valve? I want to switch mine from the dumb plugs to a valve. Thanks.

you may have 4 'drains'. it is key to determine if they have caps / valves on them or if they are open and the end.

here are the 4 that you might have and their typical colors:
fresh water tank overflow drain - white with an open end
fresh water tank drain - may be blue or white with a cap / valve
cold low point drain - blue with a cap / valve
hot low point drain - red with a cap / valve

the two low point drains with generally be right next to each other.
