Running Toilets… A problem that may appear at any time!

Have you been hearing your toilet making sounds and acting as a rogue toilet?


If your toilet won’t stop filling up or it fills up recurrently without being flushed, don’t worry; there’s a big possibility the problem may be just inside your toilet tank.

Follow these steps to learn how to fix a running toilet. Even if you’re not very “handy” you may be able to fix it. The key is in having the right tools, the right parts, the ability to read, and lots of patience. In the event you feel you need help, you can contact our friendly and professional Benjamin Franklin Plumbers. 

Please follow these 6 easy steps:

1. Remove the Lid on the top of your toilet tank:

This will help you to identify the source of the problem.

To figure out which part of the toilet is leaking see the image below:

A: Handle
B: Rubber flapper: Blocks the tank water from descending into the bowl. It is connected to the toilet flush lever above.
C: Pump which refills the tank after it empties.
D: Float which raises and lowers with the water level to tell the pump when to go and stop.
E: Overflow tube, what sets the high water level in the tank.

2. Turn off the water connecting to the toilet by tightening the silver knob on the   wall behind the toilet:

      3.  Check the connection between the handle and the rubber flapper: 
    Check the connection between the flush lever and the rubber flapper it's attached to. The chain must be short but if it is extra-long, you just need to move the clip down to replace it for one shorter.

4. Check the rubber flapper:

It could be that the flapper is not seating properly. Over time, the flapper can bend or break at the hinge, and start to leak, to check this, take a close look to the flapper and check if there are any vertical lines of discoloration, if's so, and this should be replaced. To switch it out, simply disconnect the old one from the chain and attach the new one.

Sometimes you can tweak the hinge on the valve to get it to seat properly.
If the flapper doesn’t leak and the water still runs, inspect the stopper valve.

5. Check the Overflow tube: 

If the trouble with the running toilet, pressing down the flapper doesn’t work, the cause might be theoverflow tube; which drains excess water when the tank fills too high. If you see that the fill tube is under water, cut it back so that the tube clears the water level.

6. Check the Float Position:

The traditional float is a big ball at the end of a rod that controls the valve that fills the tank after a flush.  if the tank isn’t filling up as much as needed to flush properly, make sure the float isn’t leaking.  If it is, it’ll need replacing.

It may also happen, that the float is bent, the simplest way to  fix this is bending the rod connecting the float to the pump so that the float is lower and it will signal the pump to turn off sooner. If the arm won't bend, then it might be time to call Benjamin Franklin the Plumber.
