      Answer This Question

      This could be due to some debris and grit inside the valve. You can remove the cap assembly to help clear it out. If this is a new installation the instructions on how to perform this will be in the troubleshoot section of the installation guide.

              I bought the fluidmaster and since I installed it, the water shuts off so abruptly now i'm getting the water hammer effect from it. Is there any way to adjust it so it slowly shuts the water off. Thank you

                  Blew Apart
                  I have installed several of this brands toilet fill valves over the years and never had issues. HOWEVER, this one blew apart. I made the install, turned the water on, flushed a couple of times to check for leaks and all looked OK. As I was beginning to clean up the blue cap on top of the valve blew off sending a jet stream of water to the ceiling and soaked the bathroom before I was able to turn the water off.

                    Easy to install, very simple to adjust. Used on a 30 year old toilet, works great. So far used it for a month, no more wasting water!

                    Very noisy fill valve!
                    I bought a Fluidmaster Toilet Fill Valve in August 2005 and installed it in the same month. When I flushed the toilet the valve made a high pitched whistling noise. So, I immediately called the company and told them about the problem. The representative said that the noise was normal at first, but it would subside in about a week. It has now been nine months and the valve still makes the same type of noise. This is bizarre since the company advertises the valve as being "Now quieter and faster" (see photo).The packaging is very deceptive. The Fluidmaster representative lied. I will never buy another Fluidmaster product again and I have told my many friends about the horrible experience I had with this product and the company.

                      High pitched whistle when filling
                      Bought this to replace an old ball float. It works in the sense that there’s no leaks and is functional. However, there is a high pitched whistle when the tank is filling. I thought this model was supposed to be quiet. It’s annoying

                      A high pitched sound after an installation can be due to grit or debris that's gotten into the fill valve and is not able to pass through getting stuck in the built in filter. The debris would come from your pipes and this is common. This is why we in our installation guide there's instructions in the troubleshoot section on how to flush out "purge" the fill valve so that you we are able to clear that out. If this continues after this is performed please reach out to us.

                        It is very easy to install and adjust. Because I had floodmaster installed. literally it took less than two minutes to change from beginning to end. It requires no tools at all. I only change the upper half (the gray part assembly. Didn't take off the black part from the toilet). Lift the locking ring and pull to separate and replace with the new and adjust to the hight of your liking.

                        unfortunately this is the incorrect way of replacing the valve. We provide you with a complete valve so the whole thing is replaced. We do not offer an option to where you can just take the lockring off and remove the top half and install a new top half. This can create problems. if you have any questions or need some assistance please reach out to us at 800-631-2011 or you can email us at techsupport@fluidmaster.com FluidMaster
