Preserver Series Toilet Repair Parts

Q. "I installed a new fill valve and my new valve comes on (and then goes off) for a few seconds about once per hour?"
A. This could be caused by many things. The most common is with a Fluidmaster 400. This is a great valve but be sure to install the 1/4" tube per their instructions. Use the clip that comes with it and do not just stick it into the overflow tube or it will go on and off every so often by itself. If that isn't it, take some food coloring and place it in your tank. Wait a few hours and if some of the color has gone into the bowl then you probably need a new flapper.

Q. "My Universal Rundle toilet tank has a tilt valve. How does the Fluidmaster 400A fill valve allow the bowl to refill?"
A. If you are using a Fluidmaster 400A then you must also use the Fluidmaster #599 refill tube & clip. The clip attaches to the back of the tank and keeps the 1/4" refill tube pointed towards and into the overflow tube of the tilt valve. The 1/4" refill tube must not be attached directly into the overflow tube. There must be an air break between the refill tube and the overflow tube to keep the 400A from siphoning the water in the tank and putting it into the bowl continuously causing the 400A to turn on and off continuously.
