Sanicon 700, drain hose after dumping tanks

After dumping tanks with my Sanicon 700 the hose remains relatively full of rinse water when I go to store it. It appears as once closing off the gray tank, the water in the sanicon hose no longer drains due to the fact there is no longer any air coming in to break the vacuum in the hose. I have looked at trying to install some sort of vacuum break at the hose connection to the Sanicon motor unit, due to very little space have yet to come up with a reasonable solution. Anybody else come up with anything?

I have resorted to leaving the grey valve open and lifting the hose to get the water to drain works. Once done I close the valve and store the hose.

In addition to the grey valve, I leave the Sanicon valve open while lifting/draining the hose. Once emptied, close both.

(Took me too long to figure that out)

Hi Richard, We also found that leaving the grey valve pulled open allows the water to drain out well. Before I would shake the hose to try to get the water to work itself out but I was always worried all the extra shaking wasn't good for the hose. Since changing methods it has worked much better.

I just lift up the hose at the coach end and walk it out toward the sewer connection. If you hold it up for a moment, you'll hear it start to drain. I usually walk it out a couple of times to make sure it has drained fully.

I installed my SaniCon a little differently. I direct connected the SaniCon to the bayonet fitting. I didn't want the to waste 2' of SaniCon hose, by having it come out toward the front of the coach, go behind the drain and then out the cut away in the door frame. I added a pvc pipe to the SaniCon, ran it under the SaniCon and connected the hose to the end of the pvc pipe, just before the door frame cut out.

I disliked chasing the hose to get it to drain, so I added a 6" pvc riser to the pvc pipe. Now, once my tanks are empty, I uncap the riser, which releases the suction and lets the hose drain.

Yes, you need to recap the riser or you get a little volcano.
