I replaced the water heater.. Since, then I have heard this loud horn like sound when water is being turned on upstairs.. How do I remedy?

Compliment horn with string bass and piano. Sorry, couldn't resist... locate the source of the noise-closer to faucet or water heater?

Could this noise be coming from the commode in that bathroom?

As long as you did NOT do something stupid like this at least it should not blow up.
