Leak near water pump
On this camping trip we developed a leak somewhere in the fitting going into the water pump.
I tried tightening the fitting on the water pump but there’s still a drip.
Previously I replaced the kitchen faucet and installed a shark bite cutoff.
I was thinking of replacing the black T with a shark bite elbow and replacing the cutoff going to the sink with one of those dish washer sharbite cutoffs and running a flexible supply line back down to the pump.
Is the fitting on the pump the same as on the bottom of a faucet?
Would the smaller diameter of the supply lime cause problems when using the pump.
Is there something better to replace this with?

The photo shows the pump out, just check for cracks and try to crimp the connection a bit more. Or just get a new pump connecter and crimp it in place.

If could also be the cone washer, you may want to loosen it up and look at that. Sometimes they deform a little when installed.

These..I didn't realize they are so expensive. I took a bad one into my local RV store and he handed me a handful for free!

I don't know if you have been camping in cold weather but that is the first place that cracks when it freezes. The lines can, in most cases expand a little with freezes but the connections on the water pump freeze and crack. Ask me, I know.

This happened to me as well. When I repositioned the pump and reconnected the fittings I had a small drip. Unscrewed the fitting and repositioned the cone washer and all was good. The best way I've found to install the cone washer is to slip it onto the pipe and then screw the fitting back together.

I had one deformed on a bathroom sink line, and bought a package at our local hardware store, that has mobile home parts. They looked the same in the package, but didn't fit right. Went to our local small RV dealer and bought 4 of them. Fit correctly and sealed up first time.

FWIW, I had a leak in the same place. It is hard to get to under the pantry. I tried tightening the connection to the pump inlet, thinking it was in the plastic fitting. Turns out it was where the flex hose is connected with the Shark Bite clamp. I cut if off and replaced it with a worm-gear hose clamp. So far, so good. Not sure the solid-band SB clamps are meant for the white flex hose.

I think that many be where mine is leaking now. It’s hard to get to too.

Yes, it is a b**ch in mine. I toyed with putting a quarter-turn shut-off valve in the white flex hose, since it is the back flow from city water hookup that is causing the leak. I only use the pump when sanitizing the lines, so I’d keep the valve closed until I needed to do that. But I couldn’t find a valve that I was confident would work with the white hose. Plus, if it ended up leaking too, it would be virtually impossible to replace it as it goes way out to the wall of the coach. I don’t fit in pantry-sized cabinets LOL.
