Gray Drain

[Aidan Trainor]

Hi , I'm new to the Oliver scene. We had a 5th wheel and are getting use to the Oliver Elite 11 . I have one question ,  why does the gray tank drain very slowly. The black tank drains quickly. Has anyone had or have the same issue? 

Thanks Aidan 1455

Hello Aidan.  The gray tank will drain quicker if the front of the trailer is raised a little. Raising the curb side a little near the end of the process also helps. The gray tank is long, narrow, and thin and the drain valve is on the left side rear corner of the tank. 
 

 

The gray tank level sensor on hull 313 is located where the yellow blotch is shown on the picture below. My tank level could show 0% and still have water in the rear of the tank if the nose is too high.

I did raise the front put it still seams to take a long time to drain , not of water flow. Im used to a large flow when I pull the handle , very very slow stream.
