It has no threads. It was clogged up with stuff and the water pressure blew it off. It just needs re-attached. Should I glue it or just use some silicone caulk/sealant?
We had the same thing happen to ours during our second trip out after purchase last fall. It was replaced under warranty. It wasn't even clogged, just popped off while running hot water. I think the hot water loosens up the glue. If it happens again it will be replaced with a regular hardware store faucet. I am getting to replace the bathroom sink faucet. It is so close to the edge I can't hardly use it.
