How do i unscrew the collar from a moen montecello spout assembly. there is a lot of calcium deposit.

Are you talking about the aerator assembly? You can remove it and let it soak in warm vinegar to dissolve the deposits.

YES. USE TAPE WRAPPED SLIP PLIERS

Give them a call, they stand behind what they sell. There is a possib ility that it has lifetime warranty.

Usually they unscrew. Sometimes if the faucetis in a hardwater zone the mineral deposits build up and make getting the dome off very hard. Use a strap wrench to get a little more grip, this will prevent damage to the finish and allow you to twist harder.

Information on your faucet can be found here:

First turn off the hot and cold water supply taps. Then to remove the spout you simply unscrew the spout cap counter-clockwise; you should then be able to lift the spout up and off the supply post.

The design of a hand sprayer is meant to provide a higher pressure spray (the smaller outlet size means greater velocity in the water coming out of the sprayer head). That said, there could be something constricting the water flow in your faucet. If you unscrew the aerator on the end of the faucet do you get better pressure? Is the screen in the aerator clogged with sediment or mineral deposits? If this is the case you may have water requiring periodic cleaning of the aerator.

Hope this helps.

It sounds like the fine threads on the collar are stripped. Either replace the collar, or try some locktite.

Once you remove the spout collar you should be able to remove spout and replace the orings

The spout cover is threaded and unscrews then remove spout and replace the o rings with a Moen o ring kit only use Moen brand or Ace Hardware brand

It is probably a clogged airator. If the faucet is the type where the spout is attatched to a hose there may be a screen where the hose attaches to the spout. with the spout off check the flow through the hose. If the flow at the hose is good then the problem is in the spout. Most of the time it is in the spout. you can replace just the spout if you cannot find a screen or airator to clean.
