Grey water gravity drain through a FloJet?

[RobtWms]

I'm going to use a FloJet to discharge black water into a sewer inlet that is about 3" higher than my RV discharge tube.

May I run a hose down hill and leave the grey water tank valve open to gravity drain grey water with the FloJet in place or must I remove the FloJet?

Thanks in advance!

Thanks all!

if your flo jet has a grey water bypass, you can easily drain your grey tank by gravity, if not,no. which is why I would always buy one with the bypass feature.

If you are not at home, be aware that very few places is it legal to just dump gray water like that without it going into the dump station.

If you are using it to pump black then use it to pump grey........

You'll have to take it off.
