i have a toilet that when it is flushed during the time the water refills the tank a loud vibration and hammering sound is heard in the water line. what can be done to stop this problem or what causes it in the first place? any suggestions. thanks in advance.

There needs to be a short dead end piece of supply piping (inside wall) that points upward from where the pipe goes through the wall to the shut-off valve. This enables the vibration to be dampened by trapping some air in the piping above where it is going out to the shut-off valve. Water does not compress, air does. The other thing that may help is to securely fasten the piping to the framing if you can gain access to where it is rattleing. I have no idea what causes the situation and would welcome that information if anyone knows. Also, if I am wrong I would like to know because I have a sink that is doing the same thing (plumbed it myself before I was aware). I don't want to rip into my wall If there is a better solution.

A few possibilities:

1. Water hammer-this happens when water is shut off or meets a smaller opening that the water pressure can handle and it slams into the valve end or the end of a plumbing run. Any plumbing store will sell you an air cushion to stop this.

2. Water meter- Listen to the water meter while the water is flowing to see if the noise is comming from it.

3. Kansaz- The pipes may just be vibrating against the framing and, as he said, they need to be firmly secured to the framing to stop this vibration.

Check out the check valve in the toilet.
If it opens and closes rapidly, usually due
to something loose inside, that starts and
stops the flow of water abruptly, leading
to the hammering noise. The dry riser
advocated by Kansaz is a good old fashioned
solution, but over time, the air dissolves
into the water, and the riser fills up.
When you get the hammering again, you need
to shut off the main, open a nearby hose bib,
drain the system, and then re-fill it to
trap some new air. Make your dry riser at
least a foot high, more if you have room.

Also check out your water pressure, excess pressure raises havoic with faucets, also you may have a partial obstruction in the line or ball valve.
