    Question for XLS 22 MLE Owners re: Tank Flush

    Hello All,

    DW and I put money down on an XLS 22 MLE a few weeks ago (expected arrival in April-May). Whoop!

    I've noticed the black tank flush is on the opposite side from the black/gray tank drain.
    I also notice that GD put a spray hose attachment directly next to the black tank flush.

    Question: do you guys use the spray hose attachment to flush the black tank?
    Also: if not, what length black tank flush hose would you recommend, since the black tank flush is on the opposite side from where your water source on a camp pedestal would be? (I'm gathering the required bits n' bobs as this is our first TT)

    Thank you!

    I have two expandable garden hoses and they are only used to connect from water to black tank flush. Make sure you use a water pressure regulator as well.

    Welcome to GD and the 22mle group. I simply used a dedicated hose for the flush.

    Roger that on the pressure regulator - got one on order.

    Curious what length hoses you're using for the black flush. You figure 25' would do it, or go longer?

    Thanks!

    I carry 2 x 25. I find this more practical. Only use 1 if all that is required. I have 2 x 25 for flesh and 2 x 25 for fresh. Most of the time I only need 1 but for the odd times that need 2 I'm sure glad to have it. Same with the sewer, get 2 x 20 feet or like me 4 x 10 feet (it just happen that they only had 10feet but got them for the same price). Most time you'll need just 20 but.... I got caught once.

    In addition to what others have said since this is your 1st TT, when using the black tank flush make sure to leave the drain valve open. I have read stories on other forums where somebody gets to talking with a neighbor and forgets the valve is closed.

    You might also consider getting a flush valve that attaches to the sewer drain like this:
    https://www.walmart.com/ip/Valterra-...Valve/55356021

    I use one and keep the water running thru the flush but close the gate valve to allow some build-up then open and release. Repeat several times until all is clear. Once satisfied, dump the gray tank to further clear the sewer hose.

    Hmmmm... Many people don't use a pressure regulator on the flush line, myself included.
    I have a clear elbow on the dump line. After using the on-board flush I also use a toilet wand. There's a lot more "stuff" that comes out using the wand as opposed to the flusher only.

    Good point about the pressure reg - you're sort of defeating the tank flush action while not really jeopardizing and plumbing fittings in the rig.

    I have also ordered a clear elbow for the dump outlet to ensure the tank is free of solids after the flush.
    By "wand" do you mean a sort of high pressure spray wand that you stick through the toilet valve?
