Key Considerations for Deep Tank Fill Valves
- Adjustable Height: Ensure the fill valve can be extended by twisting the shank counterclockwise to increase height, enabling it to fit deeper tanks.
- Optimal Setting: The top of the fill valve (critical level mark) should be roughly 1 inch higher than the overflow pipe to prevent backflow and ensure proper filling.
- Best Options: Fluidmaster 400A or PerforMAX models are widely regarded as reliable for varying tank depths.
- Installation: Before installing, measure your current fill valve height. Adjust the new valve's height, secure the lock nut to the bottom of the tank (hand-tighten, then a slight turn with pliers), and connect the water supply line.
Steps to Replace a Deep Fill Valve
- Turn off the water and flush the toilet to drain the tank.
- Remove the old valve by disconnecting the supply line and unscrewing the mounting nut under the tank.
- Adjust the new valve height to match the old one or to fit the depth, aiming for the top to be 3 inches above the overflow pipe.
- Install the new valve by tightening the shank nut and attaching the refill tube to the overflow pipe.
- Test for leaks and adjust the water level using the adjustment knob/screw if necessary.

I'm trying to replace my fill valve and getting to this nut has been so difficult because of how it's inset within the bowl rather than being fully exposed.Read more
