LakeBob Posted February 11, 2022 Share Posted February 11, 2022 Hello All ! Me again! Trying to run the Sanicon Flush system for the first time. Is this handle in the Gray Flush or the Black Flush position?? I think its in the "Gray" flush position. I'm probably overthinking this, however when I attempted to flush the tanks today, dumped both tanks (have the macerator system) and then tried to flush the black tank first (with handle in other position) and I did not observe any flow coming out the tank and the flush water hose did not appear to allow any flow into the tank. Do I have the handle in the wrong position? Do I have a clogged nozzle? The previous owner let the coach sit for several months with a full black tank. Am I looking at pulling and cleaning/replacing the cleaning nozzle? Thanks! Appreciate all the feedback! Link to comment Share on other sites More sharing options...
Gary M Posted February 11, 2022 Share Posted February 11, 2022 Your probably right. Not only could the spay nozzles be clogged but also usually under a sink is the anti siphon valve that could be clogged too. In your case you probably have two. Mine is directly above the wet bay under bath sink. Link to comment Share on other sites More sharing options...
Larry Maida Posted February 11, 2022 Share Posted February 11, 2022 Waste left in black tank that long is no longer liquid. Its sludge. I would buy some Green Goblin and put it ib tank with as much water as you can. After a day or so I would drive the coach with a lot of breaking to more it around. Then try to dump again Link to comment Share on other sites More sharing options...

redstickbill Posted February 11, 2022 Share Posted February 11, 2022 Bob, The handle in the photo is in the "grey" position. Letting the black tank sit full for a time will clog the flush nozzle holes. I removed the flush nozzle and after cleaning drilled the holes out to 1/16". The green goblin idea sounds like a good way to go to get the sludge out of the tank. Bill B 07 Dynasty Link to comment Share on other sites More sharing options...

redstickbill Posted February 12, 2022 Share Posted February 12, 2022 Bob, On my Dynasty the flush nozzle is mounted on the top of the black water tank on the passenger side in the wet bay, same bay as my aqua-hot unit. Bill B 07 Dynasty Link to comment Share on other sites More sharing options...
Ivylog Posted February 12, 2022 Share Posted February 12, 2022 It’s on the grey tank, as the labels implies. My labels are above the valve and reversed. Nozzles are on passenger side and on the back side of the tank on my rigs. After removing the screws that hold the nozzle on the tank, you can unscrew it without cutting the plex water line.

LakeBob Posted February 13, 2022 Author Share Posted February 13, 2022 Thanks guys, I'll get in there and take a look. I'm not able to get flow in either tank...... This should be fun! Link to comment Share on other sites More sharing options...
