How Long Should It Take to Fill a Toilet Tank?

A normal toilet would not take much time to get filled up but if your toilet takes time then something is wrong. The problem can result from several issues that include clogged up lines or float malfunction which affect water flow into the toilet. 

To ascertain the cause of this malfunction, you need to inspect the toilet tank and see which damaged component is the cause of the problem.  When you find those parts, you need to replace them speedily. If you know how to work a plier, you can make these repairs yourself to save you the cost of engaging a plumber.  

How Long Should a Toilet Take to Refill?

The amount of time it takes a toilet to refill is 3 minutes based on the water pressure but the water shut off should be completely open to ensure the maximum flow of water. In case that doesn’t work, you would have to clean your valve and pump because there may be a build up somewhere in the valve which cleaning up would open.

How to Fix a Slow Filling Toilet Tank

• Before you begin fixing the slow filling toilet tank you should check that the valve that puts on the water flow in the toilet is fully open and nothing is blocking the water line making it free from debris. Turn the toilet handle in a clockwise direction to put off the flow of the water and loosen the buildup of calcium in the water valve.

• Turn the handle counterclockwise to release the valve. Let the valve open till it stops then close the valve again and remove it from the tank with a channel lock plier.
• Put a fill line into a bucket and put on the water let the line be clear of debris.  Attach the fill line back to the tank and open the valve again. Flush the toilet to see the water flow. If there are any spills, use a sponge to soak the spillover from the tank.

• Replace the water fill line connecting to the cold water valve to the toilet if after trying this action and the tank still fills slowly. If you haven’t changed the line and your water source is hard water you may have mineral buildup hampering your water flow.

• Turn off the cold-water valve by turning the toilet handle clockwise. Remove the water line attached to the cold-water valve using a plier by turning it counterclockwise. Put a bucket under the water line to catch excess water being released from the tank.
• Detach the water fill line from the tank after you have flushed the toilet to empty the tank. Change the position of the line to a reversed mode and turn back the valve on for the water to flow to see if the problem has been corrected with the water flow.

• If this doesn’t still work then you have to flush the toilet to watch the water flow and see the component mechanism.  If the tank fills up and the float becomes waterlogged, the problem hasn’t been corrected. Turn off the water valve and remove the component that controls the float. If the float is hanging on the end of a wire arm, have the wire arm replaced. Lift the float arm to line it up to its notch to set its arm free. 

In case the float is attached to a vertical stack, remove the line after flushing the toilet and put a bucket underneath the tank. Replace the stack with a new one but in reverse mode. Complete the installation by wrapping the bottom of the float stack thread with plumber tape.  Attach the cold water fill valve back to the toilet. Put on the water and adjust your float so your tank can fill up.

Conclusion

Do not over tighten the tank components as they can easily break off. If you want you can change your toilet tank from the ball float system to a vertical stack flow system as both systems work with any toilet.
