However, the good news is that replacing your toilet fill valve is something any homeowner can do. It does not take a lot of experience with plumbing or a lot of time. However, you do need a few parts, a couple of tools, and a little bit of effort.
|Part||Replacement Cost (Labor Included)|
|Flush Valve||$60 – $120|
|Fill Valve||$60 – $120|
|Flapper||$60 – $120|
|Shut-Off Valve||$60 – $120|
Fixing a toilet fill valve (once referred to as a ballcock) is relatively easy to repair if you happen to have a common Fluidmaster brand valve. Often, repairing a fill valve is done by simply replacing the entire fill valve, but Fluidmaster fill valves can be repaired by just replacing a seal inside the unit.
As the water fills the tank, the toilet float is moving up gradually. When the toilet float reaches its set height it stops and shuts off the fill valve. Water stops flowing into the tank and the tank goes silent. … It sends excess water in the tank down to the bowl to prevent the tank from overflowing.
All you need to do is before you try to unscrew the ball to adjust the rod length on the float arm, hold the float up as high as possible. If the water continues to flow or you hear any screeching or grinding noises, then the valve is in need of replacement.
A misadjusted float is the most common cause for a fill valve that doesn’t shut off all the way. Before you try unscrewing the ball to lengthen the float arm, adjusting the rod length on a cup float or adjusting the valve tension with a screwdriver, hold the float up as far as it will go.
The valve can go bad and get to the point where even after adjusting the float, the toilet will continue to run, wasting water. … A bad fill valve will usually cause the toilet to run constantly. This is a big waste of water and will cost you money on your water bill.
Toilet flush valves come in different sizes ranging from 2 to 4 inches, depending on the toilet design. … In most cases, larger valves move water faster, resulting in a better flush. When replacing the flush valve in an existing toilet, make sure you get a valve that will work for that specific toilet.
Adjust the Fill Height by Checking the Float
The water level in the tank is controlled by an adjustable float. A float that’s set too low produces a weak flush; if it’s set too high, water spills into the toilet overflow tube and the fill valve won’t shut off. The toilet keeps running.
There are two types of main shutoff valves- gate valves and ball valves (shown in the photo). A gate valve is more common in older homes, while a ball valve is standard in newer houses. Often, you don’t need to shut off your entire water source when there’s a plumbing issue.
