How to Manually Flush a Toilet

If the water is shut off, the toilet will have one flush left as it fills up automatically after being flushed.

While it may seem impossible to use the toilet without running water, it can be done. Newer toilets require 1.5 gallons of water or less to flush, though older ones often require more. If the water is shut off, the toilet will have one flush left as it fills up automatically after being flushed.

If there is a time when the municipal water service is scheduled to be off in a home, it is recommended to fill the tub with water and use that stored water to flush the toilet manually.

Flushing a toilet without running water

Homeowners who have already used the extra flush can easily recreate another. They will need a bucket and water collected from another source to do this.

• Method Removing the Tank Lid: Remove the toilet tank lid, fill the tank with water until it reaches the top of the overflow tube, then flush.

• Method Without Removing the Tank Lid: Lift the toilet seat and lid and dump the water from the bucket into the bowl with one pour. Don’t pour the water slowly; this will only fill the bowl. Instead, pour with as much force as possible to create a strong flush. Repeat this step until the bowl is clean.

Flushing a toilet without a toilet handle

If a homeowner is in the middle of a toilet repair or dealing with a broken toilet handle, it is still possible to flush the toilet without the handle.

Remove the tank lid to access the internal parts.

Inside, the tank should be full of water. Tubes from the water supply should be attached to the float ball on top of the water. The float ball is attached to the rubber flap at the tank’s bottom, which covers the hole to keep water from flowing out until the toilet is flushed.

Since there is no handle, reach into the tank and lift the rubber flap from the bottom. Hold it until the tank empties, then let it return to its position on the bottom.

The toilet will flush as usual, and the tank will refill.

Troubleshooting the flush

To troubleshoot what is causing the toilet not to flush, remove the tank cover and check for connection problems between the handle, flush chain, and flapper. The chain can be disconnected from the handle or flapper, preventing the toilet from flushing.

Disconnected chain

If the chain is disconnected, slide a link from the loose end onto the hook at the end of the arm. When the toilet is flushed, the handle arm pulls the chain, lifting the flapper and allowing water to flow into the bowl from the tank.

Making the chain taut

For best performance, the chain should be taut, with no more than two links of slack. If it is not taut, it will not lift the flapper. Note that the chain should not be too taut, as it will pull the flapper from its position at the bottom of the tank and cause a leak.

Testing the flapper seal

Reach into the tank and shift the flapper around gently. When the flapper is down, it should produce a tight seal that keeps water from flowing into the bowl. If it’s loose and can’t be reset, the flapper may need to be replaced. Before making the decision, troubleshoot the flapper to determine the problem.

Troubleshooting the flapper

Turn off the water to the toilet with the valve behind the toilet. Flush the toilet to drain the tank.

Lift the flapper and use a rag to remove any mineral deposits on the flapper’s rim and along the hole in the bottom of the tank. If it’s worn, the flapper may need replacing. Homeowners can purchase new components at most hardware stores.

Using a bucket of water to flush a toilet is a great solution to recreate modern indoor plumbing if running water is unavailable for any reason, including a plumbing issue. However, if the toilet is still not flushing or flushes weakly, there may be a clog, or the water level needs adjusting.

If a homeowner is uncomfortable inspecting the toilet or unsure of the following steps, they should contact a licensed local plumber for assistance.
