28/Feb/2025

You’re probably here because your toilet won’t stop running, your tank is taking an unusually long time to refill, or the toilet is flushing on its own. These problems are usually caused by a faulty fill valve. This component is responsible for replenishing the tank after each flush. The valve opens up the supply line to the toilet when the water goes below the desired level. It works together with the float mechanism to regulate the water level.

Like other components of your toilet, the fill valve is not indestructible. It can wear out from repeated use or become ineffective due to exposure to hard water. A malfunctioning fill valve can lead to a running toilet, slow refills, phantom flushing, overflows, and other problems. Left unrepaired, it can waste a lot of water and render your toilet unusable. It’s advisable to replace this component as soon as you notice a problem in order to keep your toilet in good working condition and save water. Here at Mr. Rooter Plumbing, we offer professional toilet repair and replacement services. If your toilet is acting up, our plumbers are ready to respond to your service call and restore your toilet to good working condition.

How to Choose the Right Toilet Fill Valve

Compatibility

The fill valve you choose should be compatible with your toilet model; otherwise, you risk improper function. While many fill valves are universal, someolder toilets might require specific valve types. Check your toilet's model number and see if the manufacturer recommends a particular fill valve. Besides, ensure the fill valve is compatible with your water supply line.

Type of Fill Valve

Older toilets often use float cup valves, while newer models commonly use diaphragm valves. Diaphragm valves are more reliable and less prone to mineral buildup. Consider upgrading to a diaphragm valve if your toilet has an older float cup style. A diaphragm valve will not only improve the performance of your toilet, but it will also last longer. Our plumbers also recommend you choose a fill valve with adjustable height. This allows you to fine-tune the water level in the tank.

Features

When you’re replacing a toilet fill valve, it’s important to consider the features that will best suit your needs and ensure optimal performance.Some fill valves are designed for water efficiency, using less water per flush. Look for models with the WaterSense label. If a noisy toilet is a concern, choose a fill valve that's designed for quiet operation. If you plan on installing the fill valve yourself, consider fill valves that are designed for easy DIY installation.

Material

Most modern fill valves are made of durable plastic, which is resistant to corrosion and mineral buildup. Some older valves might be made of metal, but these are more prone to corrosion.

Brand and Reviews

Choose fill valves from reputable manufacturers known for their quality and reliability. Our plumbers in Nashville, NC recommend that you check online reviews from other users to get an idea of the performance and longevity of different fill valve models.

If you’re unsure which fill valve to choose, consult with a professional plumbing repair service that specializes in toilet services. A skilled plumber can perform a comprehensive inspection and recommend the right fill valve for your toilet.
