View Full Version : Black and gray tanks switched

All, I had the misfortune of having this happen to me. Anyone know of a quick test to determine if they’re switched PRIOR to buying an RV from a dealer?

What do you mean by switched

The T-valve handles were installed in the Spot of the other . So when I opened the black tank valve, gray water came out and vice versa.

So next time when I go to upgrade, I’d like a quick test to make sure they’re not switched. Mine was bran new btw

Make sure all tanks are empty, close all valves, dump a couple gallons of water down the toilet and see which valve you pull to dump it not heard of this before but is a simple fix. Tell the dealer you buy from to confirm for you

Great and simple idea. There were 3 other fuzions iat dealer for dame thing when I finally took it back. 4 hour drive. I was going to do myself but under warranty. Thx

Couldn't you keep the same configuration and just change the handles for correct color?
Or relabel them? Wondering how you know the TANKS are switched and not just the handles?

No way you drove four hours to have some $10 laborer get a Philips screw driver and swap handles, please tell me you didn't....
Probably close to a third of the RV's coming off assembly lines all over the country have them labeled wrong. If this was a big deal to you then you are in for a world of trouble dealing with RV'ing in the real world.

lol thx fir the practical replies and the last conical one. That’s funny. There was other warranty work needed addressed.
Further, not only were the handles switched but th tanks were plumbed in reverse. Black tank pipes going to gray water tank and vice versa. How do you know, cut the underbelly and look

Well, I feel better....:D No, not really. I'm sorry that there are other items for them to fix. I'm curious what about a holding tank that would be different between grey and black. (Color, of course)

That was kind of my thought. If the black piping went to it, wouldn't that make it the black tank? And the same with the grey tank. If the piping goes there , isn't it the grey tank? No matter what the handle says? Is it really that difficult to change the handles around? When the belly was cut did either tank have a sign on it that designated it to a particular use?

If I went to a dealer with a similar problem (I would not) and he started cutting the under belly we would have to have a discussion. Ans it sounds like you believed his stupid answer for a non problem?
Sorry if this hurts your feelings but you need to learn some about your unit so people can't take advantage of you.

Seems to me the difference in the tanks is in the size. Typically, RVer's generate much more gray water than black and therefore, the gray tanks are larger. I'd want them plumbed correctly too, and I'd want the dealer to do it. Best way to ensure that some $10 an hour guy is not working on your trailer is to find someone good at the dealership, and cover their palm with silver. Just like a waitress in a restaurant. We may tip for the service, but if we're regulars, best to tip enough that the waitress remembers.
