Questions & Answers
Whistling noise why and how do I correct??

We've tried two of these & both had the same problem - every now & then the fill valve kicks on by itself. We replaced the flapper as well, but even this second one is doing it. What is causing this & how do we fix it?
What you are hearing is the “Water Waste Signal” and it is telling you that the water in the tank is leaking out. If you do not see water on the floor or on the outside of the tank, then we know that the water is leaking into the toilet bowl. Here are a few things to look for A) if you have the refill tube shoved down or placed inside the overflow pipe pull it out and reattach to the overflow pipe using our refill clip. This will stop a siphon from occurring and stop the leak and B) Clean the bottom of the tank along with the drain seat that the flapper sits on, if you can’t get the tank to stop leaking with a new flapper then it might be time to change the flush valve. If you need further help, contact Fluidmaster’s Technical Service Department as we are available Monday through Friday from 5:30 AM through 5:00 PM Pacific Standard Time.
