How To Fix Your Toilet Flapper Chain – Get It Done – Ask THE Handyman St. Louis


On one of my toilets, I have to hold the handle down in order for the toilet to flush all the way.  What do I need to do?

This can be a source of frustration, especially when nothing appears to be wrong.  There are a couple of possibilities, however, and the fix might be an easy one.

Inside the toilet there is a chain that connects the flushing handle to the “flapper” (the covering which is usually at the bottom of the tank where the water drains out).  Sometimes, the chain has too much play in it.  It should only have a small amount of slack.  If it has too much slack, the flapper may not raise up all the way when the handle is pushed.  If it doesn’t have any slack, it may not let the flapper rest all the way completely down. 

In your case, it could be too much slack, so try adjusting it.  First, turn the water off to the toilet by closing the “shut-off valve” which is located under the toilet tank where the water comes out of the wall.  Turn the valve clockwise to stop the water flow.  Then unhook the pin at the end of the handle bar.  Put the pin down a few links in the chain (towards the flapper), making it slightly shorter in length.  Reinstall the “hook” or “pin” onto the end of the handle.  You’ll then need to turn your toilet shut-off valve back on, let the tank fill up, and see if this did the trick.  If not, you may need to adjust it a little more.

If the chain adjustment doesn’t completely fix the problem, there is one more thing to check.  Look at how the flapper is attached to the tank.  It should have either “ears” or a “ring” attachment.  The ears will be on either side of a tube which stands in the toilet – it’s the tube where the water goes down when the toilet is filling up.  These ears are small pieces that stick out slightly and the collar of the flapper fits into the ears.  A different way of attaching the flapper to this tube is by a ring on the flapper which goes over the tube and rests on the bottom.  Both the “ears” and the “ring” are designed to keep the flapper in place.    You should have one or the other.  If you have both, the flapper gets into a bind and won’t operate freely.   If that is the case, remove the ring and use only the ears.
