I am on a well system. WHen I turn on my kitchen faucet (Delta 61201) cold I get spurts of air along with the water. It only lasts for about 3 seconds and then will not happen again until the faucet is off for about 1/2 an hour. This is the only faucet that is affected. I cleaned out the aerator (which was clean). Do I need to bleed the system? If so what is the correct method? If not what are possible causes? Thanks in advance for your help.
