shower drains into black tank

[wayfarer]

This thread is in response to answers to my previous thread, (which I can't find).

I made the following test:
I removed the cap on the sewer evacuation pipe, opened the valve on the grey water tank, and made shure the tank was empty.

I ran water in the shower for 2 minutes and NO water came out of the sewer evacuation pipe.

The toilet and shower are next to each other, they sit on top, and DRAIN into the black tank.

Draining the shower into the gray tank involves running a pipe from the shower, going around the 50 gallon fresh water tank, (with lots of 90 degree turns), with a not so shure satisfying end result.

Since this is a HEALTH issue, I hope that the rv manufacturers who build this way, will be forced to correct the situation by Courts of Law.

I thank the folks who showed interest in this issue and offered their help.

Depending on where your line exits the tank and how the tank is tilted, it might take more than 2 minutes of water to make it run out of the tank. While you have things set up, try all other sinks to just see if they run to the gray tank. Once you get water flowing out of the gray valve, let the water stop, and then try your shower again.

Good Luck

I know this won't make you feel better, but it isn't against any rule to run gray water into the black tank. It's actually a fairly common practice (though it's usually the bathroom sink).

I really don't understand how it's a health issue.

REPLY:

When raw sewage from a full black tank flows back up the shower drain, then it becomes a health issue. It happened to me.

I should have mentioned this in this 2nd thread, sorry.

The shower on my 2604 also goes into the black water tank. Only the sinks go into the gray tank. This sure makes the black water tank fill up fast during a weekend of dry camping.


Has anyone had any luck with the dealers correcting this problem?

This really makes no sense. The designers on this one really dropped the ball with this model. Apparently none have actually used any of the units they design.

Someone on the RFS site had the same issue and it was confirmed by FR that it was the correct design for that model.

I'm really disappointed that Forest River responds in this manner. It's an obvious design mess-up and they should be stepping up to fix it!

We got a similar response from FR on a heating outlet that blew hot air at the couch from 3 inches away on our 2605. They said that it was designed that way...for what possible reason?

Same here with the shower draining into the black tank. They've clearly screwed up and are CYAing by saying it was designed that way on this model. Again, what possible reason.

They're really saying that you weren't fortunate enough to discover this on pre-delivery therefore you accepted this "design".

Pretty damn lame on their behalf!

Our 2011 Flagstaff 26RLS' shower also goes direct to the black tank. It is just my wife and I so I guess we don't generate that much black water. After 3 trips with the new TT I find that on a weekend trip dry camping, taking full showers (no "sea showers") that we only fill the tank about half to 2/3. Before I dump, I fill the black tank the rest of the way to help move the poo. I have no complaints with the shower going to the black tank. It helps me with water to clean the tank. I do understand that the black tank will fill before the gray, but if it was plumbed to the gray the gray would fill quick and you would still have to dump. If I'm going to dry camp longer than a weekend, it will be "sea showers" and the blue tank to shuttle to a dump site. I grew up boating, and spent a few years in the USCG, some aboard the sailing ship EAGLE. We often had to take "sea showers" (wet your self down, shut the water off, lather up, turn water on and rinse). Takes a little to get used to but quite easy. Just my opinion.

Questions
1. Do you have 1 or 2 gray water tanks?

2. So if you have 1 gray water tank then it is filled only by the sinks?

[kbrown1075]

Iggy,

I have one gray tank. Only the sinks go to the gray tank. Seems to be a bit of a waste, but I have not have any trouble making it work. With some calgon in the tank and the shower water, the poo slides right on out.
