Hi p-s.ogrady,
Welcome to the Heartland Owners Forum and to the family. We have a great bunch of folks here with lots of information and all willing to share their knowledge when needed.
I'm sure some of our other Cyclone owners will jump in soon, but I do not think the Cyclone every came with a filter for the water. Now, someone may have installed one if your not the original owner. You might remove the pass through panels and look behind the docking area.
Be sure and check out our
Heartland Owners Club. Join us at a rally when you can and meet lots of the great folks here and make friends for a lifetime.
Enjoy the forum.
Jim M
