Lately, when we turn on the faucet in the kitchen sink, it will pulse some air out of it. I have checked for leaks and haven't found any, water meter leak check valve needle isn't moving indidicating a leak.

What the hay could be the cause of this?? This only happens at the kitchen faucet which is a Delta brand faucet about 5 years old now.

Mine was doing this as well. I removed the spray nozzle thing (whatever its called) and then turned on the water. Seems it had a little mineral deposit build up. I let it run for a few seconds, turned it off and on a few times. Put the spray nozzle back on and it seemed to cure the problem. Hasn't had that air in the line for months now.

If your on city water and they had/have a line break in your area, probably getting it their. You getting any air from any other faucets inside or outside?

Replace the SS ball in the faucet.

Jole, do these have the springs and small rubber gaskets same as in a single handle shower?? I have never replaced the ball, springs and gaskets yet.

Buy a new fricken faucet you cheap Cajun. Momma likes change and will reward you accordingly!

Start with the simple stuff first...Is the stop under the sink wide open?

Also any work on city lines will cause air bubbles. Normally to the first raised stub on the water line!

No city water works, again this just going on at the kitchen sink.

+1 on the stops being open
also washer on stop could be loose and floating around in stop

What the hay is a "stop"? I know how to change the ball, springs and gasket stuff, the only stop I know of is the one you put in to "stop' the water from draining from the sink to wash dishes....aka stopper.

If you open your cabinet doors and look at the back wall, you should see two or three stops/hosebibb looking things (depending on if you have a dishwasher) with piping running to the underside of your faucet. One is hot, one is cold (the third would be for the dishwasher). Make certain they are open all the way to allow the water to flow through to the sink.

It will look something similar to this...

Thanks, yes the hosebibs are open all the way.

Still sputtering here...

Sounds like you might have a piece of sediment lodged somewhere, then...

ok if washers on stops are ok deltas have diverter
thingy on them remove the handle and dis asembel
and remove spout on the back of valve body is the diverter dig it out with a pick or screw and replace it
