This video will guide you through the process of repairing a new style toilet that makes a hissing sound, which is an indication that water is continuously running and you are wasting water.

The repair is quite simple and can be done by a single person without assistance.

You only need a brush (like a old toothbrush or other) to clean the underside of the flapper valve seal and the main water inlet valve seat.

Good Luck with your repair, and please feel free to leave any comments or questions and I will do my best to respond as best I can.
