There is another member here having the same issue. He stated that he removed the housing under shore water pressure. That may have caused damage on the housing or the base. Inspect the housing to make sure all the teeth are intact. Also check for cracks on the base.
Contact FR to see if they'll send you a new one. It's easily installed with two hose clamps. We've never had an issue with ours and I have removed/installed a couple of times without pressure in the lines.
