After using black water tank before heading home we drain the tanks, flush the black tank with water, fill both tanks about full with water and split a quart of detergent to both tanks. At home I pump out black and grey water tanks to our septic drain line and flush both tanks until clear. It takes about an hour to complete the total process.

If we are going for a couple of days camping we split the bathroom duty to light one in the trailer and heavy one using campground facilities if clean; this method simplifies cleaning the black tank a lot.

A Flush King is a mighty fine thing to have. It does a great job helping to keep grey and black water tanks clean, just be careful you don't overfill.

I keep my waste tanks nice and clean, there is no room for stink in my little trailer.

The "Flush King" is not going to work very well, (if at all,) with the bends and elbows in the drain piping configurations of most black water tank installations. If you don't have an absolutely straight shot into the tank, there's no way they will provide any type of flushing action where it's needed. They really don't flush anything, all they do is refill the tank with water, which could be done for free with your garden hose. None of those purported "flushing" devices or gimmicks located at the end of the discharge pipe will work when the plumbing drain lines form bends. You get a tidal action, not a flushing action. The only way to really flush out a holding tank is to actually put the pressure stream right where it's needed-in the tank, not two or three 90 degree bends away.
The "wand" inserted in the toilet type of flusher is ok if you like having to drag a garden hose into the trailer each time. Then, there is also the yukkiness of having to deal with that mess and smell each time you flush the tank. I installed a regular rotating pressure flushing sprayer in my black and grey tanks. The flushing is done with a garden hose from the outside of the trailer, so I can not only flush the tank, but watch the "results" as I flush so I know when it is running clear. One really nice aspect of this installation is that it only takes one person to flush, so it is very handy for solo travellers too.
I do use a separate hose I keep just for flushing, but it does have a built-in one way check valve to prevent any water in the line from backing up into the water supply hose as well.

Hi Greg, When Dee and I had our HILO I put an adapter on the end of our wand which fit the shower hose. With that I didn't have to haul a garden hose into the trailer. It worked well. Keith

Hi Keith,
Did you have to have an external water supply hose hooked up to your HILO shower when you tank flushed, or did you just use your on-board freshwater pump/tank for supply?

Hi Greg, We have never used on board water in any of our trailers.
Also if my memory serves me Dee used hot water to flush it. Keith

I just went out to the garage to look at the wand and the adapter is still on it. LOL

A built in spray system is better than a flush king if you have access to the tank and I have one on one of my waste tanks, otherwise I have used the flush king with good results for the past 6 years. Maybe it works well on my Escape as the black tank is high and the tubing lines are short.

I follow up the flush king with a wand if the trailer has been moved with dirty water to blast the klingons off the top and upper sides of the tank.

I have used Calgon and only calgon for years, even with our Class A. Works great and we have never had any smell. Chemical or otherwise!

When you use Calgon, rinsing is easy because it breaks down everything.


After dumping, when getting ready to leave a campsite, I pour about 2 gallons of water and 1/2 cup of Calgon for the trip, home or the next destination.


I have a friend that uses the rid-ex method, and swears by it. They spend about 6 months a year mostly dry camping. So for them this works well.


Of course before winter storage a good rinse or two helps to prepare for non-use.
