Hi - hope you can help. I have a Gerber toilet with a pilot valve 99-646 and the toilet will not shut off. It looks like the valve is not functioning properly. I have shut the water off to stop it but don't know if I need to replace the valve and if so... how do I do that?:)
Just an update to this. I changed the pilot valve and things are now working fine. Got a Fluidmaster one and it is just as good if not better.
