Where??? Low Water Drains....

[cgaskins]

Hello. I have a brand new 2015 Big Country 3650RL. I have found the drain for the fresh water tank. I can't locate the hot and cold line low water drains? On my previous RV (Montana), they were right inside the compartment that held all of the connection / hookups. We are not using the RV for a few weeks and I want to drain all the water.

Thanks,
Chris

There aren't any. You can drain the fresh water tank and the HW heater. The fresh water drain is hanging down behind the wheels on the street side. To winterize you can use either air or run anti freeze through the system. I guess if you just wanted to drain the water you could use air, but I always use antifreeze for the final storage. There is a nice write up in the Manuals section on how to do this. You'll love the 3650 layout.

I too just got the 3650 RL was told by dealer service guy there was no low point drains. Had to blow lines out when winterizing. He is going to show me when I'm ready to winterize.

Hi Chris,

As mentioned, we have some owner-written user guides that will be of help to you, including a Water Systems Guide and a Winterizing Guide. Here's a link.

Thank you everyone. I thought I was going crazy not able to find it. Kinda disappointed there are no low water drain points, doesn't make sense since to me not to have them.... I'll check out the documentation link provided by danemayer.

Oh, one more question.... I was reading in the Water System Guide and noticed the following statement: "The air pressure on the compressor should be set between 20 and 40 psi. If your compressor doesn’t have an adjustable output pressure control, you’ll need to obtain one to insert in-line." My compressor doesn't have a way to set the max pressure to a particular setting. Where does one find the in-line adjustable pressure control? I searched on Amazon and didn't see one. Maybe I am using the wrong search terms.

Thanks,
Chris

Here you are for the in-line regulator. http://www.harborfreight.com/14-in-air-line-filter-regulator-with-gauge-68228.html
You would need to add the appropriate sized air disconnects and couplings and snap it into the airline between the compressor and final destination/

Thank you!!

If you google the air pressure method, I saw the guy cautioned not to use much more than 18 PSI to blow out the lines.

Thanks for the warning!
