Do you ever hear a sound like rushing water, but aren’t sure where it’s coming from? The sound could very well be coming from a running toilet, due to a fill valve that’s seen much better days. Show
You know how the toilet valve quickly refills after a flush? That’s the fill valve doing its job. But when the fill valve gets stopped up, this is a sign that you should replace your toilet fill valve. To replace your toilet fill valve, follow these simple steps: This is what you’ll need:Tools: Bucket, crescent wrenches and rags. Step 1: Turn off the water and drain the toilet. You’ll notice residual water left below the drain valve in the toilet that will leak out when the old fill valve is loosened. Prepare for this by placing a low pan underneath the opening so whatever water drains out will go into this pan. Also, place a towel on the floor to catch any excess water that might overflow. Step 2: The fill valve must be loosened from the other side of the tank (down below) in order to remove it. Before you do that, disconnect the fill hose, which detaches easily. Step 3: Now, using adjustable pliers, loosen the nut that’s holding the fill valve to the tank. The water will begin to flow out. Once the tank is completely empty, clean out any debris, and empty out the pan before putting in the new fill valve. Step 4: Now you’re ready to install the replacement part. Put the threaded end down through the hole and hold it tightly against the bottom of the tank. Then thread the nut onto the bottom of that. Use the adjustable pliers to tighten the nut. Note: Whenever you’re tightening anything against a ceramic part, you don’t want to tighten it too much, or you could crack the ceramic. Step 5: Next, secure the water supply to the new fill valve and adjust the height, if necessary. Then, put the water feed tube back into place, in the downspout, and turn the water on. When flushed, the water should stop at the right level, with no running and no leakage from the bottom of the tank. Finally, because breakdowns are inevitable, consider an American Home Shield® Home Warranty Plan. It helps cover many of the items Homeowners Insurance leaves out — like major components of home systems and appliances that simply break down due to normal wear and tear — saving you money. A toilet fill valve is probably the most important part of a toilet tank. It is responsible for filling the toilet tank with water after every flush. Toilet fill valves are normally installed on the left hand side of the toilet tank. A water supply line is then connected to the fill valve from the underside of the tank. On the inside of the toilet tank, the fill valve is connected to the toilet float and to the overflow tube through the refill tube. Old toilets have a float ball which is attached to the fill valve via a lever while modern toilets have a float cup/cylinder which is directly attached to the fill valve’s vertical body. To replace a toilet fill valve, start by turning off water supply, flush the toilet then disconnect the supply line from the tank. Remove the locknut, unhook the refill tube from the overflow tube and lift it out. Adjust the length of the new fill valve, slide it in and secure it with the locknut. Connect back the water and hook the refill tube to the overflow tube.

How a Fill Valve WorksIn order to understand how to replace a fill valve, it is important to first understand how it works. Before you flush the toilet, the toilet tank is normally full of water, fill valve shut, flapper sitting on the flush valve opening and the toilet float at the top of the tank. This is what happens when you flush the toilet: Toilet FlapperWhen you push the flushing handle down, the lift chain lifts the toilet flapper off the opening of the flush valve. The water in the tank flows to the toilet bowl through the flush valve for flushing to happen. After flushing, the flapper sits back on the flush valve opening to allow the toilet tank to refill. Some people prefer to replace the toilet flapper as well while replacing the fill valve. In case you would want to replace your flapper this is how to do it. Toilet FloatAfter flushing the toilet, the toilet float moves to the bottom of the tank a move which opens the fill valve. Water starts to fill the tank and the float starts to move up gradually. When the float reaches its set height, it stops move and shuts the fill valve. Refill TubeThe refill tube is small tube that is connected from the fill valve to the overflow tube. After flushing and as the fill valve fills the tank with water, the refill tube send a little amount of water back to the toilet bowl. That is the water you see at the bottom of the bowl which acts as a barrier for preventing sewer gases from coming up into your bathroom. Overflow Tube.The overflow tube is a large tube in the toilet tank that acts as the tank’s failsafe. If the fill valve is defective and is continuously filling the tank with water, the overflow tube sends the excess water back to the toilet bowl to prevent overflowing of the toilet. When you have a toilet that won’t stop running, either the toilet flapper is not sealing or the fill valve is defective and therefore continuously sending water down to the bowl. Water Supply LineThe water supply line is a tube that runs from the shut off valve to the toilet tank. It is specifically connected to the fill valve and supplies it with water as and when needed.
