2022 T@B 320S Grey Water Flowing Slow

aponteluis · July 2022

When I dump the grey water tank it flows relatively slowly compared to a Retro RV camper I rented a while back. It takes a long time for it to drain. I noticed the drain diameter is not the same diameter as the dump hose connection.

Has anyone experienced the same slow flow from the grey water tank? Is this normal?

Welcome to the Forums. The gray tank is a big rectangular tank in the middle of the trailer, and the "new" gray tank drain is on the back of the tank. It could be the tilt of the trailer is making things slow?

This thread shows pictures of the trailer's tanks during the build. About 5 or 6 pictures down, you can see how they are laid out. You have to do a little mental gymnastics, as the photos show the trailer upside down. The white fresh water tank will wind up on the passenger side of the trailer, and the black gray tank on the driver's side.

Hi,

I have tried positioning the camper with the hitch side a bit higher, but still the flow seems slow.

Thanks for the link to the other post. Very interesting.

The setups on the 2022 gray tank drain locations are still pretty new to us. If you wind up with a full tank and still very slow draining, something might be a little off. I understand it is hard to tell when the drain valve is fully open, etc. Maybe another 2022 owner will know a little more.

Lots of nice Factory Tour photos in the group. Always interesting to see if you want to have a look at more.

It appears the gray water tank drain on the new 320s with a cassette toilet, no longer have a 2.5” drain from the photos I have seen, but it is about half that size, around 1 to 1.5”, so it is going to drain at about half the rate of a 2.5” drain. It takes about 5 minutes for my gray tank to drain out the 2.5” drain. A full tank will have more pressure to drain, but will still be restricted by the drain opening.
Cheers
