We had a hot water circulating system installed in our 30 yr old house so that we would have almost instant hot water upstairs. Problem was it must not have been hooked up correctly because we would also get hot water coming out of our cold side for 5-20 seconds until it got cold again. So I went under the master bedroom sink and disconnected the tubing that allowed this to happen and reconnected the original hot and cold tubes back onto their respective faucet pipes.

Problem is that now water will not come out of the faucet, either hot or cold. All the other faucets and showers work correctly now, except the one faucet where I disconnected the hot water circulation system in the updstairs master bedroom.

The water is coming to the sink just fine, and when I disconnect the tubing from the faucet and turn either the hot or cold water on under the sink, water gushes out as it should, apprently with good pressure. But when I reconnect the tubes to the faucet, the water will not come up and out.

20 minutes ago, this faucet worked ust fine. It seems like there is an air bubble or some other type of pressure issue caused by the change, almost like you need to suck on the faucet or something to get it going, but for the life of me, I can't understand why the water won't come out of the faucet.

Any thoughts?
