I personally would not call this plumber back if that was his prognosis. Sounds like it might have a stripped thread you could possibly try some loctite on the portion of thread before tightening or just replace the unit especially if it has age on it's side. Good Luck..

Modern faucets are made to be 'Eco', so less water flow and lower water consumption. If the water flow is a lot more on the hot side, there there is a fault with the cold. There aren't many reasons. Stuck shut of valve. Disconnect the braided line and open the valve into a bucket. Or the ceramic cartridge in the faucet is not correctly lined up. Or remove the strainer on the head, they can block with debris. ..

Try using a suction cup to pull the button out. Place the suction cup over the button and pull it outwards. The suction cup should create enough force to pull the button out. If the suction cup doesn't work, try using a strong magnet to pull the button out. Place the magnet over the button and pull it outwards. The magnet should create enough force to pull the button out. If the above methods don't work, try using a flathead screwdriver to pry the button out. Place the screwdriver under the button and gently pry it outwards. Be careful not to damage the button or the faucet. If this does not work, try customer support for Delta.

Taps lock up and rust. Although the outside is nice and shiny chrome, the inside is brass and they use steel screws that rust in place. Turn off the water, replace the whole thing. Take the parts back where you got them and buy the new one. When you get the new one, remove screws and removeable parts and grease them up with Vaseline.

There a little plastic tab on the cartridge that will line up with a notch in the valve body?...allowing it to go all the way in

The classic signs that it needs a new ceramic cartridge and o-rings.

Contact delta they will have that information

For me, the issue was the washer that's exposed on the underside of the circular brass piece that's exposed when you unscrew the top (I wasn't able to find any documentation that explains what anything is called). My washer looked fine, but I removed it, added some silicone o-ring lube i had and re-assembled. Stopped leaking.

Water condition, could be a variety of things with water.

They should simply twist off (unscrew)from the base. Assuming thus is a two handle faucet the "body" right below the handle will simply unscrew reveling the cartridge underneath. Hope this helps!

There is normally a filter at the end of the faucet outlet. They usually unscrew. its usually a fine mesh screen with a plastic backing mount.
