Grey tank overfill prevention

Last season we were camping for a week and were pushing the holding tanks to last a full week without having to move and dump. As we all know the level sensors are not very accurate and we filled into the bottom of the shower about an inch. The indicator that this happened was the smell yikes! How do you typically determine when to dump before this mess happens. It is a pain to have to calculate every little bit of waster used and sometimes impossible. I typically clean my tanks the GEO method. Any additional suggestions would be helpful.

No sensors are not accurate, that empty space between 3/4 and full is impossible to determine, so when you see the 3/4 light come on, then time to dump or risk giving the wife a shower foot wash she doesn't want. The black tank, my lights quit working years ago, so I pay no attention to them, but its easy to tell when the black tank is full, the toilet starts gargling when you flush. Ours does anyway. The only thing you can do is limit your water use, soap and rinse showers, don't wash clothes if you can't leave the valve open, and try to use as little water when doing the dishes as you can.

Yes I agree that is were I also typically dump it but this last time I thought we had enough room to do the lunch dishes but I was wrong. What I'm thinking of doing is adding a wash tub in the kitchen sink that fits and measure how much is used. Also in the shower add a tape mark in the shower basin to know how much water is used. Then I should know better how much is going in the grey tank.

since you filled it then you know how many days you can go before it shows up in the shower Right? Problem solved. The toilet will burp when it is close to full. Carry on.

My theory is that it is easier to pull up and dump than to clean up a mess.

Sensors are notoriously known for not being accurate. Mine do a fairly good job, knock on wood, but I hit 3/4 I start watching things closely.

There are a couple things you can do.
1. Add the SeeLevel tank monitor system. They are very accurate.
2. If I'm dry camping for a week or more, I bring my "blue" tank. When the gray tank starts to fill up, I'll transfer gray water into the blue tank. Depending on the campground and their specific rules you can dump the tank into a nearby dump station, into the campground toilets, or near trees looking for a good watering. Make sure you check the rules as options 2 and 3 may not be allowed.
Good luck.

How often do you plan to run the grey tank to the maximum? If it's only on a rare occasion, why jump through hoops to measure water. If you need to dry camp for the same amount of time in the future, cut your showers back a little and pour some of your dish water down the toilet.

With experience you figure out how often you need to dump. I know I need to dump the grey every 3 days and the black every 6 days. Laundry day I dump after 2 loads. Not too difficult. If it does back up into the shower, ours doesnít really smell. Maybe use some Happy Camper in your grey tank.

I have the garnett seelevel 2 with bluetooth, so accurate I'll run the washer with the dump valve closed. Check into it is my 2 cents.

Typically we fill the black tank much less than the grey. On a couple of occasions I have put a cap on the outlet and slowly opened the grey valve to make sure there were no leaks then open the black valve and let some grey water into the black tank. Our holding tanks will hold more volume than the fresh water tank. Our gauges are not very accurate so I tend to guess when this is necessary. This will not help with the inaccuracy of the gauges but helps when boon-docking to add time between trips to the dump station.

After a while I find I can "hear" when the grey is getting full by how the sinks drain, it's not as obvious as he burping of the toilet but I can still tell.

I do however think that See Level sensors are probably in my future, I just wish they were more easily integrated with my Home Automation system, that way I could dump the gray automatically via my macerator.

You have to learn how to conserve water and that also will allow your tanks to last longer.

We did a video on this if you're interested.
