What's this valve?

We purchased a 2018 Classic 30 last week. The dealer had partially filled the tank with water...tasted horrible so we are draining it today.

Came across this valve but there is no mention in owner's manual.

We noted that when we turned it on we got fresh water! So that I know...but what is the purpose?

Thanks!

Low point drain for winterizing.

There are two low point drains next to the fresh water tank drain. All three are located between the tires. This one was for sure giving me fresh water from the hose which is connected and turned on. I know this because I turned off the supply and voila the water stopped coming out this drain also.

The valve you pictured is an additional low point valve for the bathroom area.

Then there are two others under the trailer, almost between the two wheels mounted on the tanks, one is hot one is cold.

Then another one under the dinette for the hot water jacket in the Alde boiler.

Ok, it makes sense. I can imagine other uses...a quick bucket fill and perhaps even a cold water hand wash.

I use that valve to drain the hot water tank when I need to capture another aggravating air bubble in our hot water tank. I do have to open the pressure relief vale when I do.

2017 actually don't have a traditional hot water tank. Only a small 2.5 gallon water jacket in the Alde boiler and it is drained by a flip valve under the front dinette.

Hi

The most practical use for that valve is to do a quick flush once all the hoses are hooked up. It's right where you want it for that purpose. Open it for 20 seconds or so to run all the weird critters out of your hose and the campground supply line.
