Anyone know of such a thing? Mine's leaking like a sieve again. I rebuilt it earlier this year & used a marine sealant - maybe that was wrong - and reused the paper washer already in the unit. I've really tightened the 2 accessible outside nuts but hesitate to take it apart again. Worked fine on our March Fayetteville/Fredericksburg trip after the rebuild & now - I hide by the community dump and have the hose ready. Would hate to have to go to a new one just to eliminate the leaks.
