I am the same person with the broken toilet flanges...
In the last couple of days we have noticed a problem when we turn on a faucet, or shower, the water has a burst of pressure, sounds like a rush of air mixed with the water. It last for a couple of seconds and then the water flows normally. The second part of the problem has to do with the shut off valve located behind on of our toilets. This shut off has a "button" that you push to allow water and pull to stop the water. Several times a day we have to puch the button to allow the toilet to fill back up. It "pops" closed on its own. I think it is related to the "air" problem I mentioned at the beginning of this post. Any Help?
