Hi
We need to replace a kitchen faucet spout. Moen 87500A and the other number 7650. Our plumber said it was clogged? Where do we get a replacement spout?

Your spout is clogged with what? Why couldn't the plumber clear it? Did he even tried to snake the spout with a wire? If this were my call I would repair the old spout, however, if you wish to contact Moen here is the information.Call: 1-800-BUY-MOEN (1-800-289-6636)
8:00 am to 8:00 pm Monday through Friday
8:00 am to 6:30 pm on Saturdays EST
Closed on Sundays and all nationally observed holidays.
To contact Moen Canada call: 905-829-3400
Good luck, Tom

My wild guess is you need to replace that plumber not the spout. NBefore you call Moen double check your numbers, neither of the ones you posted come up on their list.
