OutsideToilet flush not working...

[jpf]

Has anyone had this problem or have suggestions for a fix....?

I hooked up a hose to the outside flush three days ago and it worked OK, sounded like not a lot of water pressure spraying into the black tank but I figured that may be the Park we were in.
Today I attempted to flush again and NO water is flushing into the black tank.

Checked the filter at the connection- OK.
Tried running it without the flow regulator, still no flush.

Any comments, how to remedy, or suggestions appreciated.

Jerry,

It's possible the flush head is plugged with yuk that dried. Not a happy fix. Another check you might make is the vacuum break that prevents black water from siphoning out the flush connection. On our 07 3400 it's located up in the tub enclosure. Not sure on your 05, but try to follow the hose from the outside connection.

I have the same problem now. The good folks on this forum told me where to look for the anti-siphon-check valve that often times sticks. I found mine behind the access cover which is located inside the upper pantry, It is in the wall space between the shower and the pantry. I removed it and it was not the problem. It turns out the blockage is downstream from the valve and most likely it is the spray nozzle inside the tank. I called the manufacturer and they told me I have four options. 1) hook up a water hose directly to the outlet line of the valve and try to flush from there ( I can't get enough access to do this as I can only get one hand inside the space); 2) pour some lime-away or CLR into the outlet line and let it soak; 3) add 3 times the chemicals to the tank (the kind that will dissolve TP) and let it sit for several days;4) If the above does not work, pull the nozzle from the tank and clean or replace it. Right now , I just today filled the tank and am letting it soak. I decided to add a cup of laundry detergent and 3 cups of Calogen water softener to help. If that doesn't work, I will add Lime-Away. I don't think I will ever go into the tank - I will just get a Flush King or some other device.

I would still suspect the anti-siphon valve as the most probable failure. Mine failed a year ago. I removed it and reconnected the hoses directly. I added an anti-siphon valve on the connection end of the hose I use from the CG water supply. Worked fine for 3 months until I got around to getting a replacement part from the mfg.
