Valve Handles

I a new owner of a 29PRKS and the valve handles for my Grey #1 and Black tanks are located on each side of the main drain but are not marked. Which one is black tank? Thanks.

Hi scorpiorec,

Welcome to the Heartland Owners Forum.

I'm sure another Prowler owner will chime in shortly with an answer.

Most of us have a connection that goes between the hose and the pipe on the trailer that is transparent. The purpose is to see what is going on and when the tanks are empty. If you get and use one of these, you will soon know which is which.
