When Faucet is turned on I get a loud noise. If I use the Sprayer the noise goes away.

tis more than likely a defective diverter. diverter if you have a side sprayer. If you don't have a side sprayer, check the technical info to see if your faucet has a diverter anyway.
wherever you bought it tell them and ask for a replacement.
Does it do it with only cold? hot?

Turn off the water supply valves beneath the kitchen sink. Turn on the faucet and squeeze the trigger on the sprayer to empty any water left in the supply lines, faucet and sprayer.
Trace the sprayer hose from the end of the sprayer to where it connects to the faucet. Use pliers to loosen the connector holding the sprayer hose to the faucet.
Remove the sprayer hose from the faucet to expose the male threads. Wipe the threads dry with a towel. Wrap the threads with pipe-joint tape. Twist a 3/8-inch threaded brass flair cap onto the male threads. Use the pliers to tighten the cap.
Reach beneath the sink and loosen the mounting nut securing the sprayer support to the sink or countertop. Use a basin wrench if you are unable to reach the mounting nut with your hand.
Slide the mounting nut off the hose attached to the sprayer beneath the sink. Pull the sprayer support and the sprayer from the hole in the sink or countertop.
Insert a sink hole cover into the hole left by the sprayer. Depending on the style of hole cover, it could snap in, or a mounting nut could hold it in place.

Things You Will Need

• Pliers
• Towel
• Pipe-joint tape
• 3/8-inch threaded brass flair cap
• Basin wrench
• Sink hole cover

turn the shut off to cut down on pressure to faucet,

to reduce the 'thumping' noise, open the supply valves more. If they are already at maximum, you may have a restriction further up the supply lines. Thumping is typically caused by unbalanced flow around the seat and washer, usually caused by restrictions.

It could be lime/ calcium deposits in the shower head. Soak shower head in clr and it should be good to go

Delta comes with a limited lifetime warranty. call them to get free parts. I believe you will need to check several things. Remove the spray head from the sprayer hose, point the hose into the sink drain and turn the faucet on. If it no longer makes the banging noise, replace the spray head. You need to look for a leaking spray hose under the sink also. If the faucet is making noise, replace the ball and cam assembly under the faucet handle. One other thing that I have run into is that the shut-off valves under the sink can also go bad and cause banging and vibration.

Moen has a diverter built in that will need to be replaced.

use the same steps as when you replaced the cartridge, but this time you will need to remove the spout, there is a small diverter, you will see it when spout is removed.

take this part with you to the hardware store, along with the O Rings from the spout, as they will need to be replaced also

use a non silicone faucet lubricant when putting back together

hello, you may have a air pocket in the line try shutting of the water supply and then sqeeze the handle and slowly turn the water supply back on with the hose handle squeezed on till the air is forced out, hope this helps

there is always water pressure on the sprayer when water is on. if sprayer is leaking check if trigger is stuck in . best to just change the sprayer handle it comes off at the base of the handle

If you have a Delta faucet your diverter may need to be replaced. The diveter is located under the spout (see diagram)(this is not your faucet but works the same)

2. Remove handle.
3. Remove top cap.
4. Turning spout back and forth gently lift and remove.
5. Remove and replace diverter.
