1. Fluidmaster 400CRP14 Toilet Fill Valve – Top Pick

Our top pick is this Fluidmaster 400CRP14 that comes with a flapper repair kit. So you can say it’s somewhat of a self-sufficient toilet fill valve. It’s designed specifically for toilets of 3.5 gallons’ flush capacity or more. This makes it an ideal choice for you if you have a large toilet capacity.

2. TOTO TSU99A.X Adjustable Replacement Fill Valve – Quietest Toilet Fill Valve

This TOTO Fill Valve has great performance but is too restrictive. The reason is because of the design that only allows use with TOTO flush tanks. If your tank is a good match with this fill valve, then you have solved your problem of a noisy fill valve.

The EcoPower feature and Hydrotect features are added to make this product eco-friendly. With the EcoPower feature, you get a hands-off experience for better hygiene, and the Hydrotect feature allows self-cleaning for even better protection against microbes.

Even though its design is for two-piece toilets, it can also be used on one-piece tanks as well by making adjustments. On a two-piece toilet, you get the option of adjusting both height and flow rate. You don’t need to worry about electricity bills as the valve is self-sufficient and uses electricity generated from the flowing water. There is an in-built sensor that prevents water flow once the tank is full.

Pros

  • Easy installation
  • Adjustable height

Silent Flush Toilet Valve FAQ

Why Is My Toilet Fill Valve So Loud?

Your toilet valve can get loud when refilling mostly because the refill valve has restricted water flow. If this is the case, you can fix the problem by completely opening the shutoff valve. Other reasons are the presence of debris, deteriorated rubber seal, and hardening of the diaphragm gasket inside the seal valve.

How Does Quiet Fill Valve Work?

The toilet fill valve controls the toilet flush. When you press down the flush button, the toilet flush valve is opened. When the tank empties the toilet fill valve takes over to refill the tank as it’s connected to the water mains line. The tank stops filling once the water reaches the preset fill line as it is determined using a float.

How Do I Muffle My Toilet Sound?

If you have a noisy toilet, you can muffle the toilet sound by using a weatherstrip. While this is cheap, it’s also effective. A more effective way would be to use a soundproof blanket. If the sound is coming from the opening at the bottom of your door, use a door sweep to seal the opening.

You can also soundproof the toilet walls using drywalls.

Why is There a Flush Toilet Valve?

The flush toilet valve is responsible for controlling the filling of the toilet water tank. It opens the water flow to refill the tank and shuts off the water supply once the water reaches the preset fill level.
