Plumbing problems happen. Many homeowners feel as though pipe problems and even leaking toilets require a plumber to fix. Not so.

You can make most of the common bathroom plumbing repairs yourself with a few tools and a trip to the home improvement store. A typical repair is replacing a toilet valve, namely the toilet filler valve.

What Does a Toilet Fill Valve Do?

The fill valve on a modern toilet is relatively simple. It is a tube with a shutoff valve attached. It is connected to the water supply by way of a connector at the bottom of the toilet tank.

The toilet fill valve lets water into the tank to refill it after a flush. An air-filled ball or cup connects to the fill valve. The ball floats in the tank and shuts off the valve when the water reaches the right height.

When the toilet fill valve leaks, it needs replacing. Here are seven signs that you have a toilet fill valve leaking.

1. When Your Toilet is Humming an Aggravating Tune

You may not hear it at first. If your tank has an older, ballcock-style toilet fill valve, sooner or later the metal parts inside will wear out. The valve will no longer open and close correctly.

As the water flows through the aperture, the valve will begin to make noise. First, you will hear a low humming. It can be soft enough it will drive you crazy until it becomes loud enough to trace to the valve.

This noise indicates that the water isn't flowing as freely as it should through the toilet fill valve.

2. When the Humming Turns to Screaming

When the nerve-racking hum turns to an all-out, high-pitched scream, the toilet fill valve may be working on borrowed time. The metal parts are most likely loose. Sooner rather than later, the fill valve will fail altogether.

Luckily, replacement fill valves are inexpensive. There's little need to try and repair the one you have.

3. When Your Toilet Runs Constantly

Most people think that a leaking flapper causes a forever-running toilet. Many times that is the case. Though, the culprit could also be a worn-out toilet fill valve.

To rule out the flapper, put dye in your toilet tank. Wait for several hours to see if the water in the bowl changes color. If it doesn't, the fill valve is the problem. The valve is also the problem if the water level in the tank is higher than it should be.

In either case, you can either attempt to adjust the valve or just replace it.

4. When It's NOT the Float

More often than naught, a misadjusted float prevents a toilet fill valve from shutting off all the way. Before you attempt to troubleshoot the float, make sure the problem actually is the float.

Hold the float up as much as it will go. If the water doesn't shut off (or you hear the humming or screaming that as mentioned earlier), it's time to replace the fill valve.

You may end up replacing the float anyway. You may not be able to make the right float and valve adjustments for the new float to make the water stay off.

5. When It's Not the Flapper

Another reason a toilet keeps running is that the flapper doesn't seal. If you see the water from the tank seeping around the flapper and into the toilet bowl, the flapper is most likely worn out.

Replacing the flapper is relatively easy. Buy a new flapper that is the same type as the old one. Install per the instructions on the package.

6. When You Look and Find Leaks

A leak somewhere in the tank can make your toilet run continuously or intermittently. If your toilet is leaking, you've probably already noticed it. If you haven't, it's wise to check to rule it out.

Leaks in the Flush Valve or Tank Bolts

If you detect a leak that is coming from the toilet flush valve or the tank bolts, you'll have to remove the tank from the bowl.

That way, you can replace whatever toilet tank parts are causing the leak. The usual suspects are rubber washer, tank bolts, and the toilet flushes valve gaskets.

If you find leaks around the fill valve, tighten the locknut. Leaks can come from cracks in the tank, too. Of course, if that is the case, you need a new toilet. If that is too big a project for you, it's time to call a plumber.

If There Are No Leaks

If you don't find any leaks, then it's time to look in the tank. While the tank looks full of many working parts, there are only two main toilet tank parts to consider.

The first is the toilet flush valve, which allows the water to fill the bowl during a flush. The other is the fill valve, which allows water to refill the tank after the flush.

If your toilet is running intermittently or continuously, one of the two toilet valves is usually the cause.

7. Water Is Flowing Into the Overflow Tube

Look at the overflow tube to figure out which valve is causing trouble. If the water is overflowing into the tube, the toilet fill valve leaks. In this case, a toilet filler valve repair is in order.

If the water level is below the top of the tube, the flush valve is leaking. It is enabling water to trickle into the bowl. The water is slowly and continually flowing out. That keeps the fill valve from closing completely.

Perform the Toilet Filler Valve Repair Yourself

Toilet fill valves wear out. If you own a home long enough, you will eventually need to perform toilet filler valve repair.

Let's face it, the inside of a toilet tank isn't pretty. Just remember that it's clean water running through the tank. And, the working parts are less complicated than they seem.

Replacing a toilet valve is one of the easier do-it-yourself tasks that homeowners can complete without calling a professional.
