Kitchen faucet leaking at base of spout

[AreVeeThereYet]

I have a 2017 Thor Chateau 29G. I have a recurring leak where the spout meets the faucet base in the kitchen. It goes away when I tighten the round cover, but comes back. The spout also seems to wobble more than it should when moving it between the two sink sections.



The imprinted label on the rear says:. NSF 61-9 UPC.

I unscrewed the base cover, and there is a plastic ring that is split down the middle from top to bottom.



Is the split by design, or is it broken? I'm afraid to tighten it too much, but it has to be pretty tight for it to not leak. And the spout still doesn't seem as stable as it should be.

Should I go ahead and tighten it as much as I can so that it doesn't leak, or is replacement with a better faucet a better long-term solution?

The bathroom sink has been leaking from the bottom. I keep having to tighten the supply thumbnuts on each side to stop it from leaking. I'm guessing vibrations loosen up the connections over time, as I've had to tighten it several times.

Cheap faucet! Mine was a different design but I had the same issue. I bought a “regular” residential faucet at Lowes and it dropped right in. Works better and looks better too. My bathroom faucet isn’t leaking but is ugly and plastic so I’ll be replacing it the same way as soon as it’s warm enough.

probably time for nice new faucet!

split by design. Just tighten the ring.

If you remove that ring: can you lift the "spout" up off it's base?
Perhaps there's a leaky o-ring somewhere in that pile of pieces..

If they don't have replacement parts at Home Depot, Lowes or Amazon, replace it.

We had the exact same symptoms on a kitchen faucet in one of our TTs. Seems water trapped at the base of the faucet had frozen, expanded, and split the tightening ring. It was hard to see but it leaked and the spigot wiggled. Had to replace the faucet.

Can't tell for sure in the pic but looks like an O ring at the base. Local hardware should have o rings. I would replace the ring and wrap the threads with teflon tape would be the cheapest fix or go get a new residential faucet as Pete, Ted and Lt said.

I replaced both faucets with residential units specifically to get a single lever action. It is much easier to get the desired mix of hot and cold water, especially when turning water on and off as you make the best use of tank capacity.

The split ring is there to 'jamb' into the o-ring as the nut is tightened, creating a tighter seal. As mentioned, for a fix you remove the spout, lightly clean all areas where they meet, replace the o-ring, adding a dab of silicone grease to it and reassemble. When tightening the nut, the spout will also tighten up and not wobble. Also clean the air strainer at the end, maybe it is creating more pressure than needed.
EDIT: For the bathroom unit, turn of the water supply and remove those connections. See if there are o-rings or rubber washers in there that may have deteriorated too.
