We live in a thirty year old home. 8 years ago we renovated our upper floor washroom.?
Question:We installed a new vanity including two new sinks. Just recently while running the cold water the water would suddenly just stop flowing followed by a bang in the pipes. Shortly after the problem would fix itself and the water would continue to flow.
Can anyone explain what is happening and how to repair this odd problem.

Answers:
If the sinks are located a ways away from the main line coming in to the house you may be getting air pockets in the line, and that is what is causing the banging. You may want to consider putting a water pump on the lines. The pump will keep a constant flow of circulating water in the line, and prevent air from builing up.
its just air.
it happens in older homes.
its air you can get a valve to fit at at top of your pipes to get rid of air traps
well at a certain point in the pipes there is a dent or something and it must be somewhere in the middle of the pipe becuz then it would go smooth at the top and the have a hard time for water to come out in the middle cause by a dent or leak/whole and then make the noise when it ends in the dent then it flows naturally again when it gets to the part thats even
You've got air in your pipes (has nothing to do with age) the "bang" is called "water hammer".
A valve to bleed the air needs to be installed. Have it done quickly, water hammer can damage the pipes.
We also have a double sink vanity. The banging is caused by air pockets is the water line that water is trying to pass. The water stops flowing because of the air pocket. To fix this you have too install hammers on the water pipe to minimize pockets from forming. This envolves replumbing the water pipes. We went to a plumbing store when we did ours and thet told us to install hammers to prevent banging. Hammers are extra pipes that rise above and are soldered into the main line and are capped. Hope this helps.
