Hydroflush advice

[tuckerfamily]

This thread is specific for Roo owners please. I need advice for the black tank. Already searched forum and couldn't find specifics. Would the hydroflush help with FULLY cleaning out black tank? There is a lip in our tank that doesn't allow full draining and I am tired of carrying five gallon buckets into camper to try to flush all the poop out! After several trips, there will still be special surprises floating around. Our camper is "permanently" parked now in a spot so I cannot drain like I used to at campgrounds. Also, the hydroflush has a 90 or 45 degree angle option. Which one for the Roo? BTW, I do not want to try the wand method.

What about a garden hose fitting attached to 3' of copper pipe and a 90* fitting on the end? Push it down the hole and turn it and raise/lower it as needed. The water pressure should (?) be enough to dislodge the "poop on your lip".

I made the hose/pipe things to rinse out my HWT sludge. Same theory, vastly different application...lol

You have to look at how your black tank hooks up to the hose connection. It must be a straight shot up into the black tank. Neither of my Roos met that criteria. The 23IKSS has so many bends that there's no way anything is going to go up into the tank - ever.

Plan B might be to put a hose adapter on your bathroom sink faucet and a short piece of hose from there to the toilet. You can choose - or not choose - to use a wand of some flavor from there.

Why not install a Tornado Rotary Tank cleaner at the opposite end of the tank?


I think you'll find it works better than those hydro-flush things. Watch this video:

I know that you said you wanted only Roo owners, so please disregard this if you choose.

Roo's aren't much different than a lot of other RV's in regard to black tank draining and flushing. In our previous TT I used a version of the Hydroflush and I still use it on our current RV.

In my opinion it will certainly help in cleaning your black tank if you use it correctly.
First you'll need a valve on the outlet side of it, so you can close off the flow. Because in all likelihood it's not going to shoot a stream of water straight into the tank. There's too many crooks and bends in the plumbing for that to happen.

1) Drain the tank as best you can.
2) Close the outlet valve on the Hydroflush and turn on the water into it.
Let the water run until the black tank is about half full.

WARNING: DO NOT leave the flush unattended, AND keep a close eye on the level in the tank!

3) Once the tank is about half full, open the outlet valve fully and let the tank drain again.
4) Repeat these steps a couple of times and your black tank will be as clean as you can get it.

I have tried the wand method and certainly not happy with the need to drag a garden hose into the RV. That said, just locally ordered one of these to get around this issue; first saw the hose attachment here on a recent thread. Figure I will be able to easily and adequately flush the system from the sink faucet at the dump station or last campground we use.

Realize you mentioned not wanting to try the wand, but I figure with this enhancement it should be OK. Won't arrive until next week.

Regarding the conclusions of the video, our 233S has two 90 degree elbows in the black tank drain, so looks like only the only reviewed product that will work is the permanently mounted devise. I didn't like the potential installation hassles. Also the dump station we most often use does not seem to have a working fresh water hose, so none of the featured methods would be very handy anyway.

My 23SS has two bends in the black tank discharge line as well. As you've stated a back flush is not effective.

When I empty the black tank, I stand over the toilet and dump a 5 gallon jug of water into the tank just as it is almost empty. This help flush out almost everything.

When I get home I fill the tank up with water and drain it again as well as use a wand down the throat of the toilet........seems to work.

What do you guys do with the wand when you're done? My DW would be very concerned about where I put it.

[Dave Lyon]

I hang it on a nail on the garage wall. The wand shouldn't get dirty.

Thanks.

But my DW will tell you: anything you put down your toilet is going to "get dirty."

And I don't have a garage.

Thank you RockfordRoo for posting that great Youtube video. My conclusion of filling the tank for several flushes seems to be the best option. I am so glad I watched that video. The same situation is happening to me as in the video. No matter what I do, there are still huge "floaters" inside the tank after flushing. I am going to buy a faucet hose attachment and fill the tank until floaters are gone. We only camp once every month and would really like the tank free of poop when we leave for the summer. Summer heat in Texas is 110 degrees with internal camper temps higher. Can make for a stinky combo!
