Holding Tanks

We have recently purchased a 2017 Keystone Sprinter 33FWFLS and have noticed that it appears to have multiple holding tanks. We cannot figure out how to switch tanks when one is full. Is there a way to do so? The panel lights showed that one was full, but that the others were not. Any help would be appreciated.

You don't switch between them, they service separate areas of your trailer. Someone with your trailer will probably chime in soon to help.

Thank you so much! We have been trying to figure that out for a while. That makes perfect sense now. Some areas may fill up quicker than others, depending on the use. Thanks again!

The function of your waste holding tanks should have been explained to you during your walk-through at the dealer. In the absence of that info - you can go to Keystone's website and look up the specs on your trailer to determine the number and size of your waste tanks. There are many different configurations. For example: Our Cougar has one 38 gallon black water tank that holds waste from the toilet. We have a 38 gallon grey water tank that holds waste water from the shower and bathroom sink and there is a 38 gallon grey water tank that is plumbed into the galley sink. There is a dump valve for each of these tanks but they discharge through a common waste pipe/fitting. The sensors on these tanks are known to be very temperamental and inaccurate. Therefore, the tank you think is full may not actually be full. Have you successfully dumped these tanks? You might try reaching out to your dealer for assistance - good luck

You didn't state if they use separate drain hoses or a common drain. You can add a valve in line at the drain hose and open both valves. This will equalize the tanks to the same level giving you some space. If you have to use separate hoses (usually found on some older models) then you would have to have 2 hoses connected together with a Y or T fitting to use this method.

I am assuming your rig is a 334 instead of 33. If that's the case it appears you have 34 gal. tanks. 1 for black and 2 for gray water. You should have 2 separate drain handles for those.

You said one is filling up and the other isn't. The gray tanks are typically spit between kitchen and bathroom. Are you primarily using one of those locations causing one tank to fill faster than the other?

Thank you all for the help, and yes, it is a 334 instead of a 33. We didn't have good customer service from where we purchased the camper so we are learning as we go. We had a fifth wheel prior to this one , but this one is ten years newer so a lot of things are different.

Our awning button also doesn't work so we have to use the remote only for that. You would think with a brand new camper all of the things would work. We love it, but not the dealership.

Thanks again everyone!

I don't know how close you are to the dealer but I would insist that they do a thorough inspection with you. Sounds like you need to take it back for the awning button anyway. Make them take you through it and go through everything. If you can arrange that post back here and there are lots of posts plus a PDI checklist you could take back with you so that you can cover everything and get more familiar with the workings of your trailer.
