Fluidmaster does not offer repair manuals for its products, but does offer installation instructions on the Fluidmaster website that explain how to install or replace parts. These instructions are in PDF format, open in a new tab or window in your browser when selected and are available in both English and Spanish.
From the Fluidmaster home page, select the Do It Yourself link at the top of the page, then choose the Installation Guides option. Select the instructions for your particular model, and the instructions open in a new tab. The instructions note to use only Fluidmaster parts when making installations or repairs and claim Fluidmaster is not responsible for use of non-Fluidmaster parts. The instructions also feature a troubleshooting section, which covers issues such as the fill valve not turning on and the water level in the bowl being too low.
Under the Do It Yourself tab, Fluidmaster offers solutions to common problems with broken toilets, including the toilet fill valve running non-stop and new toilets not flushing correctly. Also under the same tab, embedded YouTube videos from Fluidmaster’s YouTube channel show how to do some repairs. Some of these videos demonstrate how to repair toilet tanks and flush valves.
