Half a year after replacing the O-rings on the kitchen faucet, it’s dribbling again. This time, the symptom looked like a leak from the top of the faucet, which implied the three O-rings on the Spacer plate rather than big O-rings that seal the spout.
You can see the O-rings look different on the old and new spacers …
Indeed, the old O-rings are flattened out. It’s most visible over on the right edge of the lower ring; the top ring is new.
Replacing them is no big deal; follow the directions in the earlier post to get everything apart. But: only half a year?
Here’s a view of the diverter on the back of the column.
Notice that the larger O-rings that seal the spout to the column had glued themselves to the column and left shreds when I removed them. A narrow strip of Scotch-Brite scouring pad, applied shoe-shine style, cleaned the O-ring debris off the column and made it nice & shiny. I suppose as long as they slip freely on the spout, then it’s all good, but there are new ones in place now.
I used a bit more silicone grease on the O-rings this time; we’ll see if that makes it better or worse.
