Don’t you hate flushing the toilet and there’s no water running? It’s frustrating, especially if you have to use a commode in an emergency. But in this article, I’m going to help you find out how to flush a toilet without running water. 

When I moved into my home, I was worried about this situation and immediately began searching for solutions on the internet.

I found that other people have had the problem of having no running water in their bathrooms at one point or another.

So I decided to help out such people through my article. So let’s begin this guide to teach you some possible ways to deal with such a frustrating situation.

To flush a toilet without running water, you can use a bucket of water. Pour the bucket of water into the toilet bowl. Flush the toilet. The extra weight of the water in the bowl will make it easier to handle when you flush.

How Much Water Do You Need to Flush a Toilet?

How To Flush Toilet Without Running Water

Toilet flushing is a science. The amount of water it takes to flush a toilet depends on where you live, how many gallons the toilet uses per flush, and how much solid waste is in the toilet bowl.

The average toilet used by an American household uses 1.6 gallons per flush or gpf.

That’s not a lot of water—but if you’re living in an area where your water utility charges by volume rather than by usage, the amount of water that goes down your drain can add up quickly.

To be safe, ensure you know how much water your toilets use to flush (and how much each one costs).

If you’re looking for ways to save water at home, look into dual-flush toilets: these models use less water per flush than standard models do by offering two buttons—one for liquids and one for solids.

That allow users to choose between using less or more liquid when they need to go number two.

How To Flush Toilet Without Running Water | Pro Methods

Well, you can easily find many ways to flush a toilet without running water on the internet. But I found that most ways are complicated and need special techniques.

So that’s why I have come up with the most straightforward 2 pro methods by which you can easily handle this intense situation.

1) Flushing A Toilet Through a Bucket Of Water 

How To Flush Toilet Without Running Water

Flushing a toilet through a bucket of water is a straightforward process. It involves using a bucket full of water outside the house to flush your toilet.

This method works great if you are experiencing an emergency or want to eliminate some waste in your toilet.

You will need the following:

  • A bucket of water
  • A plunger (if you have one)

Step 1: Fill your bucket with water, then carefully pour it into the toilet bowl.

If there are any problems with flushing, repeat this step until everything has been flushed out of the bowl and is down the drain.

Step 2: Once everything seems to be gone, use your toilet brush to scrub around inside the bowl and clean up any remaining messes.

This will prevent nasty smells from forming in your bathroom later on!

Step 3: If you don’t have a plunger handy, you can use a bucket of water to flush out any remaining waste from the drain pipes by pouring it down.

The drain slowly from several different angles and locations around the pipe opening until no more water comes back up into your sink or tub (this step will also prevent odors).

Flushing Toilet By Manually Filling The Tank 

How To Flush Toilet Without Running Water

If your toilet doesn’t flush, don’t panic. It’s easy to fix the problem by manually filling the tank with water.

Here’s how to do it:

Step 1: First, turn off the water supply to the toilet. This is usually located on the wall behind or near the toilet.

Then, flush out as much water as possible from the tank by opening up both sides’ valves.

You may need to empty some more water of it before proceeding with your manual filling process (though this isn’t necessary).

Step 2: Next, fill up a bucket with warm water and pour it into the back of your toilet tank. Until it reaches about one inch below its top edge (if using more than one bucketful of water, be sure they are all warmed beforehand).

Be careful not to overfill your tank because this could cause damage!

Step 3: Turn on its supply valve again after filling your toilet tank with warm water.

So that any excess spills out into your drain pipes instead of through them into your house’s sewer system—or worse yet—onto your floor.

Why Your Toilet Might Not Have Running Water (And How to Fix It!)

How To Flush Toilet Without Running Water

1) A Clogged Sewer Vent Line

If your toilet does not have running water, your sewer vent line may be clogged. This can happen when waste builds up in the pipe, preventing air from getting into it. If your toilet doesn’t have running water after flushing, this is likely why!

To fix this issue:

  1. Turn off the main water supply valve under your sink or behind your toilet.
  2. Remove the cap from your drainpipe and use pliers to remove any blockages inside the pipe (like hair).
  3. Once everything is clear and open, put everything back together in reverse order, so you don’t lose any parts.

2) Empty Toilet Tank 

If your toilet has no water, it’s probably because the tank is empty. This might not be the case if you have a tankless toilet, but if you have a traditional toilet, this is almost always why.

If your tank is empty, a handle on the side should look like a little bucket with an arrow pointing down.

Turn that knob until it’s pointing up (or in the opposite direction of the hand). This will open up a valve that allows water to refill your tank.

Once you’ve done this, push down on the plunger to empty any remaining water from the bowl into your septic system—the same one used all day by everyone in your house.

3) Leaks In Toilet 

The most common reason your toilet might not have running water is a leaking toilet. Several things can cause a leaking toilet.

But if you notice that your toilet is constantly running and not just when you flush it, chances are it’s leaking somewhere.

Here’s how to fix it:

  • Check the flapper valve inside the tank (the rubber flap that keeps water from running out when the tank is full). If this is damaged or cracked, replace it with a new one (they’re only $5 at your local hardware store).
  • Check the fill tube (the hose that connects to your faucet) for cracks or leaks. If any cracks or holes exist in this part of the system, replace them!

4) Leak In Flush Valve

If you have a leaky flush valve, your toilet might not have running water. The valve controls the flow of water from the tank to the bowl, so when it leaks, the tank will fill up with water and overflow.

First, check the supply lines for leaks by spraying them with soapy water to fix this problem. If there are no leaks, you will likely have a leaky flush valve.

To replace it, turn off the water supply to your toilet and remove the old part by unscrewing it from underneath.

Then attach a new one using Teflon tape or plumber’s putty, available at any hardware store.


In the end, I hope that now you know how to flush a toilet without running water and tackle this intense situation more professionally next time.
