Thanks for the suggestions Trek, Dan, and Robb. We will check once we have the canister apart again so we can take the o-ring to somewhere to match it up.
So far, what we did was just slather a whole bunch of silicone plumbers grease on our stretched out o-ring and screwed it back on (we're out of K-Y
) No leaks! *yay!*
And let me add that we went to Home Depot and bought a pair of GE carbon paper filters for about $13. We also saw a Whirlpool pair for about a dollar less at Lowes. We learned that as long as they're a size
C1 , they'll fit any canister brand.
Note: Anybody who is having problems with the water flow in their coach, be sure to replace this filter!! We thought our flow problem was our water pressure regulator-throttle thingy we put on our hose. Boy! What a difference it makes replacing that filter! Showers are SO much better, washing dishes is really easy now! I'm literally a "happy camper!"
