Gray going into the black tank

We have a 2017 Freelander 27QB and had it winterized by Camping World. Took it out this past week and the black tank filled after 2 days. When we went to dump we had nothing in the gray tank as it all flowed into the black. Any idea why this can happen. It worked fine when we used it last fall. Any help would be greatly appreciated.

Both grey and blank tank dump valves left open with a cap on the sewer connection?

Nope that did not happen. Both valves were closed with the sewer hose connected. Pulled the black tank first when done closed the black valve and opened the gray. Nothing came out. Had done dishes and taken showers so water should have been in the gray

Need more info.
Do you normally fill black in that time period?
Was sewer hose connected whole time?
If so then, perhaps, grey gate valve is leaking. Grey never filled with use because it just ran out.

The grey valve leaking would be my guess. Of course, if it's leaking into the black tank, that's another problem. I don't know if those valves leak from the outside in....

Open the gray valve and turn on the water. see if it runs out. Then close it and see what it does.

My bet is on leaking gate valve, too.

The gray has to be open slightly or leaking. Even if it were left open, it would not go in with the black water with a hose attached. I'm thinking it went down the drain.

Normally we do not fill in that amount of time. After reading everyone’s replies am thinking we have a leaky valve

Thanks for the quick responses, do think we have a leak. Will be checking it out. Thanks again!

Is it possible you have more than one gray tank and thereís a separate valve for it. My 20cb has two gray tanksÖ.one for shower and a separate one for two sinks. Each has its own drain valve

That was my first thought as well. I looked up that year model and everything shows it as one gray tank.

Seems there’s alot of missing or wrong information online. I’d suggest crawling underneath to figure out what’s what. I had to have someone pour water in each drain while I listened to the flow in order to figure out which drains went to which tanks. I wrongly assumed the bathroom sink and shower went to one tank and the kitchen sink to the other. It turned out the shower had its own tank and the two sinks went to the other.

I wouldn’t be surprised if you find another tank, possibly with a missing valve handle. On mine a previous owner replaced the black handle with a gray one! It doesn’t affect its operation, but definitely important to know!

As a general rule, I’d recommend crawling underneath anyway and try to identify tanks, exposed plumbing, exposed wires, etc. I’m frequently amazed at how little owners know about their own rigs. I’ve learned alot by physical inspection vs manuals and online forums. Sometimes people with similar models have different options and coachmen manuals are lacking

Could be inaccurate for sure these days. Looking underneath might reveal another drain, but you can't see anything else without taking down the cover. Opening the drain while someone runs water in each area will certainly reveal what goes to that one!

I didnít mean you should open the tank valves. Rather, I had someone pour water into the sink and shower drains while I was underneath and listening to where the water went in order to identify the two gray tanks. The gate valves stayed closed.

Once you identify the tsnks, itís fairly simple to visually see the pipes leading to the gate valves. I highly suspect you have a second gray tank based on your description.

Btw, to more easily get underneath I use something similar to this mat https://www.amazon.com/Reversible-Ma...dp/B00V94ZE84/. I found one at Walmart and looked specifically for something thatís smooth, which makes it easier to slide underneath (a poor manís creeper). It provides a small amount of cushion. Prior to having that, getting underneath was a difficult (and painful) process and I ruined a few t-shirts and got scraped up a bit. Look for one thatís smooth and not too expensive as it will get trashed if you use it a few times. You could also use a big piece of cardboard in a pinch, but I find the mat to be a good investment.

You have to remember that many owners have a hard time finding that noisy vibrating fresh water pump. I'd bet even fewer will stick their head underneath and find where running water is stopping. Anyone can see water coming out of the drain valve though.

These user forums are for asking questions and providing advice/solutions. I posted what worked for me. Everyone is free to do whatever works for them.

Some people will try DIY. Others will pay big $$ to have an ďexpertĒ figure in out for them (often the expert will collect the $$ without solving the problem). I prefer to DIY, which comes in handy when traveling and thereís no expert within walking distance.

I hope youíre able to solve this particular mystery. Personally, I highly doubt the ďslow leakĒ theory. Dripping would be visible.

When/if you figure it out please post what you discovered for the benefit of others looking for answers

Not all of us have x-ray vision

X-ray vision isnít necessary to see dripping water or a puddle. If you donít want to look underneath your rv, then donít look. Sounds like blinders are more your style.

Considering youíre not the OP, perhaps you should re-read this thread. Iím suggesting there might another gray tank. If so, there would be THREE valves and the OP hasnít yet found it. Could be the handle is missing.

If indeed thereís another gray tank, thereís at least 2 ways to locate it and one would be very messy.

Okay, sure. I stand corrected.
The OP obviously has an additional grey tank - one thatís remained hidden from him over at least a couple of seasons of usage since, as he stated, everything was fine last fallÖ.

Reading is fundamental, comprehending more so.

Iím sure youíll have a blissful day.
Iím out.

Our 2021 27QB Leprechaun has three shut off valves. Two black and one grey. There is a black behind the right rear wheels. The other black and grey are at the hookup pipe on the left rear side under the coach.

We have found the bathroom sink goes into the black with the toilette. The kitchen sink and shower go into the grey.
