Toilet Slow To Fill: Common Causes

First and foremost, understand that this kind of issue is not your fault. The majority of plumbing issues happen due to worn-out valves, seals, washers, and other parts. In the case of a toilet slow to fill, the most likely reason is because of debris back-up or a worn valve. Typically, a toilet takes a minute or less to fill back up after flushing. If you notice it takes longer, you need to address the issue as soon as possible. 

Worn Out Supply Valve

A worn-out water supply valve is a common cause of slow filling toilets. The supply valve typically comes out of the wall or on the floor next to your toilet. The connection allows water to fill your toilet, and there is a knob to turn that cuts it on or off. All it may be is that the knob needs to be turned a couple more times to the left. If that doesn’t open the valve all the way and help, you may have a deteriorated valve or a clog. If the valve needs to be replaced or unclogged, it’s best to call your local plumbing expert

Fill Valve Issue

Fill valves are attached to the fill tube. If the valve on this tube is worn out or clogged in any way, you could wind up with slow filling. When you check the valve, make sure it’s attached to the fill tube and shut-off valve. Replacing a fill valve is simple, and you can find one at your local hardware store. 

Clogged Fill Tube

Frequently, a clogged fill tube is the reason for a toilet slow to fill. We’ve got some quick tips on how to clean out the fill tube and get everything up and running again. First, you’ll want to shut off the water supply valve. Unscrew any hardware attached to the valve, and use a brush to clean out the tube. Next, open and close the supply valve a couple of times to clear out any debris. Reassemble everything and watch to see if the toilet fills up normally now.
