about a month ago our pipes started humming when the water was turned off

in the last few days our water pressuer is not like it used to be.
when the humming starts i can open an faucet and it tops right away?
would draining the water pipes and refilling them help? *would anything
else help?

thanks

Is it a single hammer noise, or a continuing hum??????
