I live in a manufactured home & am city sewer line. But when we run water or flush a toilet we can hear the water. Sounds like it is running into an empty tank under the house. I even hear water sometimes when we don't even have any on. It's like i am hearing the neighbors water when it runs.
Thanks for any help.

Try adjusting the valve under your toilet as a globe valve is designed to throttle and excessive velocity can cause lots of strange sounds and piping erosion
