Both my bathroom faucets bang when the hot water is turned on. If I turn either one on full blast it will bang, and the water will pulsate and spatter, the shaking will continue and then the water will stop coming out and the shaking/bang will still continue until I turn off the faucet. If I turn the fuacet down a halfway it will act like a normal faucet. What can I do about this?

Hi Tm tacp:

You need to shut the water off and remove the stem units and replace the washers in place. You may even need to replace the seats if these are worn.

If the faucets are extremely old it may just be best to install new faucets... ;)

Let me know if you have questions...
