Float Valves

Finding the Perfect Float Valve

If your toilet is running or leaking, it may be time to replace the float valve. The float valve, which is found inside the toilet tank, automatically controls liquid levels and ultimately prevents the overfilling of tanks. Most float valves are universal and can fit the standard tank opening on any toilet; however, it is always a wise idea to ensure compatibility before purchase since valve stem length can vary.

How Do I Know If I Need a New Float Valve?

Float valves can wear out over time or become corroded, and when this occurs, you will need to replace the mechanism. Here are some signs that your float is ready for replacement:

  • A Running Toilet: A leaking flapper or worn-out fill valve can result in water flow that creates a running toilet. To determine the issue at hand, drop dye into the water within the toilet tank. If the water bowl has not changed color after several hours, this is indicative of a faulty fill valve. To keep high water bills at bay, you will want to quickly replace your float valve. Doing so is straightforward and requires basic tools that you can find around the house.
  • Humming Noise: Noise may occur if the valve is not opening and closing smoothly. This noise often begins as a low humming sound and eventually develops into a screeching noise when left untreated.

How Do I Change a Float Valve?

Replacing a float-valve system is a relatively straightforward process when you're armed with a little know-how. To do it, simply follow the steps below:

  • Disconnect Supply Line: Turn off the water at the shut-off valve and drain the tank by flushing the toilet. After this, disconnect the old supply line and remove it.

  • Adjust New Fill Valve: Next, adjust the height of the valve. The marking on top of the valve should be at least one inch above the overflow tube.

  • Insert New Fill Valve and Connect Supply Line: Once you have inserted the new fill valve and connected the supply line, attach the refill tube and angle adapter to the overflow. When this is complete, turn the water back on, allow the tank to fill, and then adjust the water level.

What Type of Material Should I Choose?

Float valves are made from a variety of materials, including brass, stainless steel, and cast iron. The right material depends on the application at hand, as well as on your personal preference.

  • Brass Valves: Brass float valves are highly resistant to corrosion, making them a solid option. They are often a more economical choice over stainless steel valves.
  • Stainless Steel Valves: Stainless steel floats are often preferred for their increased sturdiness and resilience over typeslikeplastic valves. These parts, while often less economical, hold up better over time and are less likely to leak.
