400A - Genuine OEM Fluidmaster Universal Toilet Fill Valve

400A - Genuine Fluidmaster Universal Toilet Fill Valve

The 400A Genuine Fluidmaster Universal Toilet Fill Valve is a high-quality original Fluidmaster replacement component designed for residential toilet tanks. It controls the flow of fresh water into the toilet tank after flushing and shuts off the water supply when the correct tank water level is reached.

The Fluidmaster 400A features adjustable height and an anti-siphon design, making it a versatile replacement for many standard toilet fill-valve applications. Fluidmaster's official documentation identifies the 400A as a fill valve and provides installation instructions for replacing an existing toilet fill valve.

Available from Appliance Kingdom in Canada, the 400A is a practical replacement when a toilet has a noisy, slow-filling, leaking, or continuously running fill valve. We serve homeowners, landlords, property managers, and professional plumbing and maintenance technicians across Canada.

What Does the Fluidmaster 400A Fill Valve Do?

The toilet fill valve controls the water entering the toilet tank after a flush. As the tank empties, the fill valve opens to allow water back into the tank. Once the water reaches the appropriate level, the valve shuts off the incoming water supply.

The 400A uses an adjustable float-cup design and adjustable height to help control the tank's water level. Fluidmaster's installation instructions also specify the correct positioning of the refill tube and critical-level components during installation.

A properly functioning fill valve is important for reliable toilet operation and efficient water use. A worn or defective valve can allow water to continue flowing, refill the tank slowly, or create unwanted noise.

Common Symptoms of a Failed Toilet Fill Valve

A faulty or worn fill valve can cause several common toilet problems, including:

• Toilet tank fills very slowly

• Toilet continues running after the flush

• Water does not shut off completely

• Noisy or vibrating fill valve

• Water continuously enters the toilet tank

• Toilet tank does not refill correctly

• Excessive water usage caused by a valve that does not shut off properly

Fluidmaster specifically describes the 400A as a replacement solution for noisy, slow-filling, leaking, or inefficient toilet fill valves.

Will Replacing the Fill Valve Fix My Toilet?

If the fill valve is responsible for the problem, replacing it with a properly installed 400A can restore normal tank filling and shut-off operation.

However, a continuously running toilet can also be caused by other components, such as the flapper or flush valve. If replacing the fill valve does not resolve the problem, the complete toilet tank assembly should be inspected.

Compatibility & Ordering Guidance

The 400A is a universal toilet fill valve designed for use with many standard toilet tanks. Fluidmaster lists the 400A as a universal fill valve, with adjustable height to accommodate different tank configurations.

Before ordering, compare the existing toilet's fill-valve configuration and available tank space with the 400A installation requirements. For unusual, specialty, or one-piece toilet designs, verify compatibility before purchase.

If you are unsure whether the 400A is suitable for your toilet, provide Appliance Kingdom with the toilet brand and model information so compatibility can be checked before ordering.

Installation Overview

Replacing a toilet fill valve is generally considered a straightforward plumbing repair and can be suitable for an experienced DIYer.

The basic installation process involves shutting off the toilet's water supply, flushing the toilet to empty the tank, removing the existing fill valve, installing the replacement valve, connecting the water supply, and adjusting the tank water level. Fluidmaster's official instructions provide specific installation steps and warn against overtightening the locknut because excessive force can damage the toilet tank.

No electrical or gas connection is involved, but the water supply should be shut off before beginning the repair. If you are uncomfortable working on plumbing connections or cannot identify the correct installation configuration, professional installation is recommended.
