Cold water no longer running to one sink. Also lots of air
I moved in about a month ago to a 1920's duplex. Most of the plumbing was re-done when the house was gutted in the '90s, and there was an addition added (with PEX plumbing, incidentally) in 2001. When we bought the house the addition had been winterized. I've de-winterized it and now have a few problems. Firstly, the tub in the full bath will often sputter and spray air when you first turn it on. Also, the sink in the same bathroom will sometimes sputter and have grey, bubbly water come out of it. Now, even worse, there's -no- water pressure at all to the cold water in that sink. The hot is still flowing (and was sputtering air again tonight) but you turn on the cold and there's no air, no nothing. The other fixtures in that bathroom, however, are working fine currently. Any suggestions on what could be causing all the air in the lines, or what could be keeping my water from flowing tonight?
THanks,
Eric
Incidentally, I'm on city water, and the addition to the house (where the problems are) is on the ground floor, and gets its water from a line in the main part of the house (only 1 feed in from the street). There are -no- problems with the main part of the house.

Hi Eric,
It's for sure you have a problem in the Pex system, I hope they installed a shutoff on the Pex branch to the addition. You may have two separate problems. Let me address the lack of water first.Turn off the water to the lavatory and open up the valve. One handle or two knobs? If one handle, shut the water off to the tap and dismantle the tap and pull the cartridge. Check the inlet ports for any trash or debris that may be built up. If two knobs, shut the water off to the hot side and dismatle the tap. Shine a light down in the open tap body and check the seat for any thing that may be blocking the flow. Now I want you to place a pan over the open tap to prevent splash and turn on the water shut off valves, (or if you have shut the entire house down, turn on the water, count to thirty and turn it off) there should be a full stream coming out of the open valve body.. What you are doing is flushing the supply line and the open tap body. Do that and see if it doesn't help get water back. Get back to me with the results. Regards, Tom
