Keystone Fuzion 371 Blackwater valve ?

[aceofspades]

In my compartment of my 2015 Fuzion 371 toy hauler, there is a pull handle for both the grey and black water tanks. Question, how do I access the actual valves that open and close? My two black tanks empty with the one handle, but the back bathroom (tank 1) will not hold liquid as it seeps out. I have since installed the external twist-on gate valve assembly outside so I do not have clump build up. I see all the videos on how to change these valves, but how do I get to them??
Thank you in advance.

We have that same model and found out the hard way that there is another black tank pull near the left side rear wheel for back bathroom. It's possible that valve could not be properly closed?

hmmm, I will have to take a look. Thanks for the suggestion!
Same year and model?

I've got a Keystone too, I believe the vales are actually enclosed under the belly. You'll need to drop that cover that's between the frame rails. Follow the cables and you'll know when belly pan to pull..

You've got a 2015.. Or take it back to the dealer.. Or try and flush it (lots of water, then dump) - unlikely it's a worn seal, but it might be installed poorly.

Ours is a 2014 model. The only other "valves" we have besides the two black and one gray that I mentioned above are the low point drains located on the other side near and behind the steps to the door (one is red, one is blue), we only released those when we winterized last fall.

I have even a worse problem. I can not get my black water or my gray water valves to open. does anyone know where these valves are located under the 2015 Fuzion 371 5th wheel. I don't feel like removing all the under cover

I think you will find the rear pull for the Black tank (which is also the rear gray tank (sink only) right behind the main rail where you found the pull.

We have a 2016 Fuzion 325 and the grey water seems to be going into the black tank? we were going to drain the grey water but nothing came out and showers had been taken so there should be something?
