I have a 2013 Columbus 320 RS and currently camping in Colorado.
I am trying to drain all my tanks, pulling all levers, one at a time, but no drainage is happening on all three tanks. Big problem and I have no idea why it is happening. Everything worked fine a few days ago, now something is stuck?
Any ideas?
its Monday....go on line and get forest river telephone number and call them. Explain where you are and situation and ask for suggestions. Obviously something is wrong.
If you do not have have success in locating the number, CALL YOUR DELIVERING DEALER. (REVERSE MY NOTE. CALL DEALER FIRST IF POSSIBLE).
You will receive suggestions from the forum, BUT, all tanks not draining is a HUGE issue.
In the event you cannot resolve, as a last resort, call large campgrounds where you are or going to be and see if they have MOBILE RV TECH REPAIR services posted on their bulletin board that they can recommend.
If nothing, seek out the nearest large town near you and do the same.
I assume you DO NOT have a special warranty plan. IF YOU DO, get their ok first.
There is an All Pro Water Flow Service in Colorado Springs. Not sure how far you are from there. All Pro is a RV Holding Tank Service - they specialize in plugged tanks. Look under the dealer tab at All Pro Water Flow to locate the Colorado Service.
320RS should have a black tank flush. You can turn that on with valve open to check. You may be able to push blockage out if there is one. I also agree that the tanks may be empty. Valves may have not completely closed and sealed.
