winterization questions for Elite

[Ben Phinney]

We have a new Oliver Elite trailer and a steep learning curve.  Doing winterization for first time - mostly successful but need help with several issues.  

1.  Water came up through the bathroom drain although we had emptied all water tanks. Why ?  We subsequently poured some antifreeze down the drain per the book.

2. When flushing the outside wash station water pump and hand pump had so  pressure such that it was difficult to get antifreeze to come out of the hose.  

3.  Is there a valve in the black water flush system?  Unable to find under the street side front dinette seat.  This was not mentioned in the book but was in the video.

 

We would welcome any thoughts.

For item #1, make sure you opened the gray tank backflow preventer valve (by pulling the handle near the floor by the toilet, or with the switch in the closet if you bought the optional auto-valve feature).

For item #3, there is no manual valve for the black tank flush line.  Just hook up a water hose to the flush fitting on the outside of the hull (use a dedicated hose for this, do not use your drinking water hoses) and turn on the water.  Keep an eye on it though so you don’t overfill the black tank and have it overflow the toilet.

The two valves under the forward dinette seat are the black tank DRAIN valve and the gray tank back flow preventer valve, both of those are remotely actuated by cables.

I'm not certain that this is what you are asking about with item #2 but ;

When using a hand pump in order to inject anti-freeze into the exterior ports (fresh water and city water), it helps if you open a faucet on the interior of the Ollie while you are using the hand pump.  This allows the pressure you are building up to go somewhere.

There were some trailers built that did have a valve in the black water line. It was accessed from under the forward dinette seat.

Ours has a valve that shuts off the flush line going into the black tank.  It looks like the fresh water tank drain valve.  Like Steve says, it’s under the forward dinette seat.  Mike
