    Black Tank Flusher inlet

    Hello,
    Regarding the use of the 'Blank Tank Flusher inlet', I read that you should NOT use your "fresh water hose".

    ...Why is that -- could stuff in the black water tank backflow into the hose or what exactly?

    With that, should hook the hose directly to the city water source faucet, or can I hook to the fresh water docking station and pull the city water from there?

    Thanks!

    I think a lot of people do use their fresh water hose and I think that's ok. The water that comes back out of the flush inlet is clean water due to the vacuum breaker in the line. The place where you could potentially run into issues is where you leave a hose connected all the time, but you should be ok if you only hook it up for a flush and then disconnect.

    I'm not really sure what you are asking with your second question.

    It “could” contaminate the hose but highly unlikely
    But just get a separate hose and hook it to the campground spigot
    Easy and costs a few bucks

    Edit. Unsure how and where you would hook up to the docking station anyway
    To run a line from there all the way to the black tank flush would take more work imo considering the flush is likely right beside the source. On my model anyway
    YMMV

    My Water Docking Station has an Outdoor Shower connection -- and which also means I wouldn't have to disconnect from the City Water faucet.

    In addition, I could use "hot" water -- if that would be better than cold coming from the City Water faucet.

    Given that, is this a sanitary, and possibly even better solution?

    ...Oh, and I'll definitely use a separate dedicated "black water hose", either way

    I know a lot of people on here are strictly against using their drinking water hose for flushing or even using a y and having both connected at the same time due to the possibility of cross contamination. The flush system those have a vacuum valve. I think the risk are really low. Where you might run into an issue is using your drinking hose at a dump station, specifically if its indicated that it's non drinking water.

    Thanks, but the hose I use is not really the question here: It's super easy and cheap to use a separate hose for black water.

    The question is really more about whether it's ok to hook up to my Holding Tank Outdoor Shower -- as opposed to the City Water faucet?
    And does this also give me the advantage of being able to use "hot" water to flush the tank?

    I think if you're that worried about contamination that you would use a different hose, you cancel that benefit by hooking the outdoor shower from your freshwater system to the flush inlet.

    I dont think it's a problem either way you decide to do it, just saying that your proposed method defeats the purpose of a separate hose.

    Additionally, your freshwater outdoor shower water pressure is most likely a bit lower than that of the spigot. You want water pressure for the tank flush. I dont think the hot water is a huge benefit.

    That is exactly what I do. I keep a short hose with a quick disconnect attached to the shower port. I plug it in to the black water flush line when it is time to rinse. I dump the hot water in with the rinse before we leave to go on the next leg of the trip. It is recommended to never leave a hose attached to the flush port when you are not actively flushing. Bad things happen if the water gets turned on at all.
