FW drain valve

Rick-s · 12-27-2015, 09:36 PM

We have a 2016 Forest River Forester. Can't locate the drain for the fresh water tank. Found a blue hose under the unit that appears to be coming out of the FW tank but there is no valve to release the water. Any suggestions on where the release valve is?

i dont know but my previous rig had a cap that you unscrew at the end of that blue hose

The valve should be in a compartment immediately above the line that extends below the floor. There is a door inside that compartment open it and find a filter and the blue line should be to the right of the filter and a valve in the line.

It helps to know the model # of your unit also. Our 3171 is in the same place as jwa795.

But you can not see it. It is a quarter turn valve behind the black partition. For me, it is easier to use my left hand to reach and turn.

Thanks for your replies. I found a compartment under the shower that has a small filter and a blue hose behind it but no valve and that appears to be above the FW tank, to high to drain the tank. I've gotten under the unit and can see a blue hose coming out of floor. There is not a cap or valve on that hose. It goes straight up in to the floor. I've looked in the outside compartments to see if the valves could be there. But nothing. The FW tank appears to be under the bed. The top of the tank is at floor level. With the slide out there is about 10 in between the bottom of the bed and what appears to be the top on the FW tank. So I can see the top of the tank and what must be the bottom from under the unit with the hose coming down. Where is the valve?

Post what model you have and you'll get the correct location I'm sure.
Here's the location on mine, 2701DS.

Sorry I didn't post the model. If is a 2016 Forester 2431S. Since my last post, I got under the unit again. The blue hose coming down from the FW tank had a bunch of foam insulation covering about 4 inches of the hose. I thought the drain valve is under the foam. Cut away the foam and could see about 6 or 8 inches up to the bottom of the tank. No valve. Still looking.

I would check the compartments on the driver's side rear where your bed is with the F/W tank. Someone will chime in soon with the location I'm sure.
Try running the water pump and listen in the compartments. That's where it should be.

I think the mystery of the FW drain has been solved. There isn't one. I called several RV service departments. All but one said they had no experience with a Forester 2431. They one that did said they had one in to be winterized and found no FW drain. They couldn't get in touch with anyone at the factory because they are closed this week so they used the pump to drain the tank so that is what I did.

Don't disagree with what you were told, but I can not believe anyone would build an RV today without a FW drain. Especially if you found the line hanging through the bottom of the RV??

Sagecoachdriver · 12-29-2015, 04:39 PM

Do you have a water filter? I would think the valve would be there. If there is a blue hose hanging down next to the red one underneath, there's a valve somewhere! Where's your water pump?

Sagecoachdriver · 12-29-2015, 06:12 PM

Brochure says you have a water filter. It will be with that and the water pump. Listen and find the pump. Where do the red and blue lines under the MH come out, pass, middle or driver's side and how far back?
In the photo, have you looked up under the white board and up in the corners?

I have to agree with Flybob, there has to be a FW drain somewhere. Will be interesting to see where it is on your unit when you find it.

Sagecoachdriver: The photo you posted is like our unit. As you suggested, I looked up under the white board and there is no valve there. Looking to the upper left with a flash light I can see the blue hose coming out of the bottom of the FW tank and there is no valve there. So I have followed the blue hose coming out of the tank to the end under the unit and haven't found a valve. Interesting, if the blue hose is connected to the tank what keeps the water from draining?

Where is the water pump/ filter? You've walked around the entire bed looking for a trap door? Why haven't some of the other MTS Forester owner chimed in. Please, when you do find it, post where it is. This is crazy!

What is the switch in the photo?

Sagecoachdriver · 12-31-2015, 01:34 AM

From your description of the where the blue pipe goes, that must be it in the photo! Then behind the plate to the left of the valve will have your winterizing tube and valves. Under the vanity should be your water pump and filter.

Rick-s · 12-31-2015, 05:52 PM

Sagecoachdriver - On the back side of the bed is a white 4-5 in screw off opening. That opens to the side of the FW tank. There is a blue pipe running from the drivers side. There is a valve on it. I take this pipe to be the city water hook up because is has nothing to do with the tank. In your photo the valve you have circled is the winterizing valve. It is part of the water system under the shower. Open a panel under the shower and there is the water pump and the hose to draw the pink stuff through the pump. The water filter is under the sink. From where are you getting the photos?

Is that valve in photo just a 2 position or could it be a 3 position? I would think the valve should be somewhere by the water pump and winterizing. It's crazy!!!
