After you dump it add 2 gallons of water to the tank

wiscjc · 09-25-2011, 07:26 PM

I added a second opening in the other side of both the grey and black water tank. Drilled a 1.5" hold with a threaded cap. I can flush out both with a wand or just a hose. since the sensors are on the other side of the tanks, both are also flushed out completly, works great...JC

The wand can work wonders cleaning the sides of the tank. Be aware and careful of back-spray; move the wand up and down and turn it around. Adding several gallons of clean water and a bottle of Calgon water softner, liquid, will really help clean. Once you are SURE the tank is clean, the sensitivity of the sensors can be adjusted. Remove the panel from the wall; sensors have adjusting screw on the back of each row of lights.

Just one more word: one poster left his grey water valve open after the whole smear. I wouldn't do that - I just made that mistake. I was washing clothes and taking a shower and didn't want the grey water tank to back up into the tub when too full. I forgot to shut the valve and found that those dreaded sewer smells invaded the coach. With an open valve and nothing flowing through it, it is wide open to the sewer! Seems I had lost the water in a p-trap and the smell just came in. Never again!

I always leave a dog loop in the end of my hose before it goes into the ground. Self made oder trap.

Personnally, I leave both closed till they are full. The grey fills up twice as fast as the black in my case. Since I am usually hooked up it is no big deal to walk around sometime during the day and pull the valve. Had a service center tell me to do this to help flush the solids out of the grey tank. I use the grey water to flush the hose after dumping black water.

I add about 5 as our tank is 45 gallons and it takes some water to fill the pipe to the drain valve and I want the chemicals in the tank, not the outlet pipe.

Thanks to all.

We were all newbies at one time, I am just 6 weeks into the "Class A" thing and I will tell you I am still learning a whole lot as it is so different from my Class C. Happy Trails and use the RV often.

Also tried the reverse flush with a valve that is built into the Rexhall. Didn't help. If I order one of those wands that you stick down through the toilet and hook up to water hose, how do you know which way to aim the jet ?

I had a problem with one of my sensors in my black tank. It was reading 1/4 full after I finished emptying it.

What I did was buy one of those wand thingies with the spinning head (Camco ??) for about $16. I hooked it up to my backyard spigot and used FULL power, while moving the wand up and down and all around. I really had NO idea where the sensors were, but it really didn't matter as the spinning head covered a 360-degree area.

I did it for once for about 2 minutes, checked the sensor and it worked. And just for good measure, I did another 2 minute cleaning session and the waste water that came out was almost clear.

I'd give the wand a try if I were you. What have you got to lose ? 16 bucks and a few minutes of your time ??
