I've replaced all the O rings, so now the only drip is in the spray. About 1/3 of the cone of spray just sprays crazy and dribbles from the hole in the top of the domed piece that screws on. The hole looks round to me. I can't tell if the inside of the dome is uneven.... it's pretty small and dark in there. I've cleaned it with Barkeeper's Friend on a Q-tip, but there is still some staining. If the problem is inside, how would I smooth it out?
If the problem is in the male part, what should I be looking for that might cause this?
