If you’ve noticed that your toilet tank has started to fill up slowly and you don’t know what is causing this issue and how to fix it, you have come to the right place. This is a very common problem and there are a couple of reasons why this is happening. None of them are way too expensive or complicated to fix. Identify the reason first so you will better know which method to apply when fixing the toilet tank.
Reason Why It Fills Up Slowly
Water pressure in your home has the biggest impact on how long the toilet tank will need to fill up completely. Still, in most cases, refilling should be done in less than a minute. Therefore, if it takes noticeably longer for your toilet tank to refill, it probably has an issue that must be solved.
Here are three reasons why your toilet is filling up slowly including solutions.
✓ Water Supply Valve Issue
Below the toilet tank there is a knob sticking out of the wall. That knob is your water supply valve. If it isn’t working properly or if it is partially closed and stuck in that position, it could be the reason your tank is filling up so slowly. Another potential issue related to the water supply valve is a buildup of dirt and debris. If the buildup is too big it could not only restrict but also stop the water flow.
How To Fix
If you think the water supply valve is causing the problem, the very first thing to do is to ensure that it is completely open. If it is fully open and still not providing the right amount of water you should contact a licenced plumber to see if there is a debris buildup.
✓ Waterlogged Float Ball
The ball floating on the top of the water controls the amount of water flowing into the tank. Occasionally the float ball gets waterlogged. If that happens, it won’t allow the water to flow into the bowl properly.
How To Fix
Take off the tank lid and check on the water level. If the tank is only partially filled, you may have an issue with a waterlogged float ball. Luckily, taking out the old ball off the float arm and changing it for a new one is a piece of cake.
✓ Fill Valve Tube Issues
The purpose of the fill valve tube is to control the water level inside the tank. After some time, the fill valve can clog, wear down or even shift out of alignment. Any of these situations can easily cause water flow problems.
How To Fix
The fill valve is supposed to be mounted on the left side of a toilet tank while the tailpiece should be extending through the bottom. If that is not the case with your fill valve, it could be a sign that the fill valve is causing the issues with the toilet tank.
All in all, fixing a tank that is filling up slowly can be pretty easy when you know where to begin. In certain situations you may need to consider hiring a licensed plumber to help you. On the other hand, fixing this issue may be as simple as swapping a tiny piece like the float ball.
