Draining Fresh Water Tank.

Is there an easy way to dump the fresh water tank?

Yes, remove the cap off the drain line, blue I believe is for the fresh water tank and red for the water heater. They are located in same area as the dump connection.

I am surprised there is not a drain valve. Both of my older trailers had them.

On the Puma I had people telling me my tires were coming apart because the water vapor looked like smoke.

The red and blue capped lines should be the low point drains. On mine, there is a fresh water tank drain underneath, slightly behind the axles. It has a pull handle similar to the grey and black drain handles. It's a white 1 1/2" gate valve.

What trailer do you have? On mine there is a 2.5 in gate valve with a handle. dumps it in about 5 minutes, depending on the amount of water in the tank.

The blue and red lines are low point drains and won't do a complete (or fast) job of draining the fresh water tank. There is a large-bore drain on the fresh water tank with a pull handle. You should find a white T-handle underneath the trailer. It looks just like the handles on the waste tanks but is a different color. On most models, it's just behind the rear axle on the street side. Crawl up under there and pull - but reach as far as you can or you'll get wet!

Imagine 2800BH. I see you have the Momentum. I crawled around tonight looking for that valve and do not see one.

About 6 minutes into the video it shows the fresh water drain. It is in the front curbside and is a twist valve.

Yesterday I found that valve, but I am really glad you sent the video. It has a lot of useful details.

I have a 2021 GD 29RS. If I drain the water from the two low point drains, why do I need to winterize (put antifreeze in my fresh water tank)?
If there is no water then why?
Thanks
