well what dose that mean, If your on a septic system depending on the size the holding tanks all vent to the atmosphere. Maybe you should stay at a nasty hotel so you won't be offended by odors at all. Or maybe be located next to the tank itself. Have you ever seen the 6" pvc pipes coming out of the ground, well that is where it's vented. People who do not clean up after there dogs is way more offensive to me, then leaving my gray tank open. What is in your coffee today?....

OK, the holding tank indication system is the most misunderstood system on the RV.

1) The lights work by the water/slime making a connection between the level probes through the liquid to the "common" probe. In the attached photo, the far left "single" probe is "common" and the right side three probes indicate "level" by the different resistors attached. As the probes are covered, they route power through a resistor pack and the voltage drop is interpreted by the control display by turning on the appropriate light. (see attached diagram).

2) Wall slime will also make an electrical connection (of varying resistance) even though the tank is physically empty (a common error).

3) Since the OEM probes are flat "buttons," TP does not "hang on them" (a commonly - an erroneously - reported cause of bad readings).

4) Readings may be "marked" F, 2/3, 1/3, AND E; but the actual amount of liquid in the tank at each light depends on how the installer drilled the holes and the shape of the holding tank.

The E light is always on provided there is a minimum voltage of 6 volts available to the display panel. It is the "ON" light.

In the photo, the 1/3 light is actually a "NOT EMPTY" light since a single flush will turn it on.

The 2/3 light is actually a 1/2 full light and the F light is actually about 7/8 of a tank.

(Also note that the "BATTERY" condition display is NOT F, 2/3, 1/3, and E. It is C for charging, G for GOOD, F for FAIR and L for LOW) As an FYI, when the G light goes out you have less than 50% capacity remaining. The L light will stay lit till the battery is destroyed.

I flush out my sewer hose with the same hose I use for flushing the black tank. Works just as well as gray water.

I only need to use gray water to flush my hose Mr. PHD when I'm not on full hook ups. Other then that I use my black tank flush valve to flush my line and tank after I close off my gray tanks so I do not need to do that, I guess you don't know how to flush your tanks? Your answer to dosen't even make sence to me with you even explaining it. What solids are going to fall into my gray tanks Sir? I also use odor waist break down products in my gray tanks when I'm not hook-up to full sewer . Sir your opinion is false and I stated Where dose it state to not open your gray water. So you went to a seminar and some yahoo told you that, well he's wrong to. Do you even know how your plumbing is ran? I guess not by the new statement you just made. Have a good day I know I will...... PS You must have got your PHD off the internet now I'm really impressed.

So I really do not or will not stop leaving my gray tank closed when I connected to the sewer. That is your and his opinion only. Let me say this when you camp and it drops below freezing to protect my system I always drip water, If I drip water all night the tank would overflow. Your a little bit far out there to advise someone to keep it closed, that in my opinion........

Did you say two different things, you keep yours closed, but will not advise someone to keep it closed?

And yes, each camper does get sewer gas coming from it.... that is why there are roof vents. But some people, like the dear wife's poopy don't stink.

I like using the grey water as it flushes with a big gush to flush any chunky residue out real quick and finish with the black tank flusher just running clear water. Some folks just like to be different for whatever reason and that's just fine.

Good to know. I don't recall it being labeled on my display so I has always assumed the F, 2/3, 1/3 labels applied to both rows of leds.

I also never really trusted that as a reliable measure of battery capacity and just use it to double check whether or not I had hit the disconnect when the TT's in storage and the slide's in. (My disconnect is hidden when the slide's closed.)

Still, good to know.
