Why Is There No Water in My Toilet Tank? 3 Reasons Why it Happens

So you’re about to do the number two and can’t wait to get it out of your system. Then you notice… there’s no water in the toilet tank! Calling a professional plumber near you would be the first thing homeowners do. The good news is fixing a toilet tank without water is not as complicated as you think. 

Reasons why there is no water in your toilet tank 

Discovering that there’s no water in your toilet tank could be upsetting. Imagine you’re about to get your bodily waste out of your system, only to see that there’s no water in the toilet tank! How are you going to solve it? 

Before that, you should identify possible reasons why: 

Issues with the trip assembly 

The trip assembly is part of the flush handle connected to the toilet tank. The flush cycle may not function well when the trip assembly is positioned improperly or unintentionally blocked when the tank lid is on. Hence, there’s no water flowing in the toilet to flush with. In this case, you have to check your trip assembly. Remove the toilet tank lid and see if the trip assembly is broken or worn out. If it’s one of these things, you should replace it immediately. 

You need to adjust the fill valve.

New toilet models have a float cup instead of the traditional float ball. Meanwhile, the fill valve manages the water flow to fill the tank with water. Sometimes, the fill valve slips out in place, so you have to adjust it from time to time. 

Remove the toilet tank lid and check the float cup. There is an adjustment rod that connects the cup to the fill valve. To raise the cup and increase the tank’s water levels, twist the screw clockwise on the water level adjustment rod. Then, flush the toilet and wait for it to be refilled with water.

You need to replace or reposition the float ball.

Old school toilets have float balls to manage the tank’s water levels. It sits above the water and stops the water flow when it reaches a certain level inside the toilet tank. When the ball is set too low, not enough water may flow inside the tank. 

First, remove the toilet tank lid. Slightly bend the float arm upwards. The ball should move up and let water flow into the tank. If the water level remains low, you might have to replace the float ball. 

How to clean the toilet tank 

Toilet experts recommend cleaning your toilet tank at least twice a year to prevent the growth of mildew and the formation of rust, grime, and other minerals that could damage the tank parts. 

To clean the tank, you can use white vinegar (distilled or the basic white vinegar). It is an all-natural cleaner that won’t break the bank. Remove the tank cover, and pour the white vinegar into the tank (don’t drain out the water before doing this). For best results, let it sit for 12 hours, then flush the toilet several times. Turn off the water valve and drain the water completely. Use a scrub brush to clean the inside of the tank, then turn the water back on, flush, and check if the tank is already clean. 

Or you can use drop-in tablets to clean and prevent the formation of rust and mildew in your tank. Contact a professional plumber in Mt. Pleasant, TN,for your plumbing issues.
