What is the toilet fill valve?

A fill valve is that part of the tank that usually refills the tank with water. It is located in the tank of the toilet just beside the overflow tube. The fill valve can be considered the heart of the toilet, as, without it, the flushing system will collapse badly, and there is nothing much to be said about the fill valve. Sometimes it behaves badly, and it could even explode if the condition worsens. This article will discuss the grim consequences and solutions of a fill valve explosion.

Why does the toilet fill valve explode?

The main reason why the fill valve explodes is mainly because of the uneven air pressure in the system. When a toilet is flushed, the water forcefully moves to the bowl to clean the waste, and when it flows into the bowl from the tank, it backdrops a decent amount of pressure as the tank starts to empty in a rapid manner. Sometimes, the fill valve explodes out of the tank to adjust the pressure.

The consequences of the toilet fill valve explosion

The fill valve explosion is not a good sign for a toilet, and it has further consequences that might be harmful to the bathroom,

The explosion might damage the internal parts of the tank like the trip lever, overflow tube, chain, and even the flapper, which can feel the aftereffect of the explosion. The fill valve explosion may create immense pressure on the water supply system. Even the tank and bowl can be damaged, which is a complete mess in these circumstances. This explosion might also destroy the internal drainage and shock the system. The lid of the tank will be the worst victim during the explosion.

How to Repair an Exploded Toilet Fill Valve?

The repair process for the toilet fill valve is very simple. Let us see the complete procedure in a short time.

Step-1

First, address the entire toilet’s condition and assess the damage level. Then turn off the water supply line and pull off the lid of the tank. Flush the tank if the button is working or manually empty all the water from the tank.

Step-2

Then, unscrew the fill valve nut and take out the damaged fill valve using a wrench. Check the inside parts. Everything is okay.

Step-3

Take a new fill valve and implant it in the place where it belongs, right beside the overflow tube, and tighten the screws by using the wrench or pliers.

Step-4

Finally, turn on the water supply line and see if the fill valve works. If it works, the tank will be filled in no time. That’s how you must change an exploded and destroyed fill valve.

Wrapping up

An explosion is always a horrendous incident; if it is happening inside the bathroom, it could be disastrous. So you need to check the insides of the toilet parts very frequently, especially the water fill valve, which needs a regular check-up. To avoid this horrendous situation, you must finish prudently and always take time between two consecutive flushes so that you may avoid the explosion.
