Toilet Bowl Drains Completely When Flushed (Solved)

Did you just try flushing your toilet only to find that the water drains completely, leaving behind a dry bowl? You are not alone!

Well, the good news is that it can be fixed with a little bit of effort.

In this post, I’ll explain why your toilet bowl drains completely when flushed, and how to fix it.

#1 Clogged Vent Pipe

A clogged vent pipe is a common reason why a toilet bowl drains completely after flushing.

The vent pipe is really important for your house plumbing. It lets air into the pipes so they can drain properly and stops them from getting sucked in.

What happens when this vent pipe becomes clogged or obstructed?

It can create a suction effect, which literally pulls the water out of the toilet bowl after flushing.

The vent pipe can become clogged due to various reasons, such as debris buildup, bird nests, or even small animals that have found their way into the pipe.

And in older houses, the pipe might have rusted or worn out, causing blockages too.

Solution: Clean The Vent Pipe

You can easily fix this by unclogging the vent pipe.

You can try using a plumber’s snake or auger, which is a long, flexible cable with a corkscrew-like end, to dislodge any obstructions in the vent pipe.

Or you can use a wet/dry vacuum to suck out any debris or blockages.

However, if the clog is particularly stubborn or the vent pipe is difficult to access, it’s best to call your plumber.

#2 Clogged Rim Jet Holes

The next reason why your toilet bowl drains completely when flushed is due to clogged or blocked rim jet holes.

The rim jet holes are the little holes under the rim of the toilet bowl.

During a flush, water is released through these holes, creating a siphoning effect that helps clear waste from the bowl.

What happens if something blocks these holes?

The flushing power can get too strong and make the water drain too fast!

Mineral buildup is often to blame, especially in areas with hard water.

As time goes on, minerals from the water can build up and block these small holes, stopping them from working like they should.

Solution: Clean The Rim Jet Holes 

Go and grab a small brush with stiff bristles or one made just for cleaning toilets.

Now gently scrub around the holes to get rid of any gunk.

You can also try using a mild acidic solution like white vinegar or a cleaner meant for getting rid of mineral deposits.

But do read and follow the instructions on the cleaner, as some can be pretty strong.

If the clog won’t budge, you might have to take off the lid of the toilet tank and flush water directly into the bowl while scrubbing the holes. 

This can help loosen up any stubborn buildup or debris.

#3 Faulty Flush Flapper, Chain, Or Handle

The flush flapper, chain, and handle are super important parts of how your toilet flushes.

When you flush, the flapper, usually made of rubber or plastic, lifts up to let water from the tank flow into the bowl. The chain connects the flush handle to the flapper, and the handle is what you use to start the flushing.

If any of these parts are worn out or broken, it can make the bowl drain too fast.

For example, a worn or cracked flapper can let water leak from the tank into the bowl, causing a strong flush that empties the bowl too quickly.

And if the chain is too short or too long, it can stop the flapper from sealing right, causing the same problem.

Solution: Replace Them

Check out the flush flapper, chain, and handle to see if they’re showing any signs of wear, damage, or if they’re not set up right.

If any of these parts look worn out, cracked, stretched or broken – replace them.

After replacing, adjust the chain properly so the flapper seals tightly after each flush.

Sometimes, just tweaking or switching out these parts can fix the problem.

It’s always a good idea to deal with any broken bits as soon as you notice them.

If you don’t, they could not only make the bowl drain too fast but also waste water and possibly mess up your toilet over time.

Wrapping Up

If none of the above solutions work, it may be time to call a professional plumber to inspect the toilet and the plumbing system for more complex issues. 

They can diagnose the problem accurately and recommend the best course of action.
