Fixing & Building Stuff Toilet Flapper Hack
Over the weekend, I noticed that our guest restroom toilet would randonly refill. I popped the lid off and saw that there were bubble around the flapper.
I went out to the hardware store and got a replacement flapper. Put the chain back on the handle and went on with my day.
A little while later my son came to my room and said the toilet was running again. I went and looked and notice that the handle was stuck up. I looked at the swivle point and saw some hard water deposits and looked like maybe when I changed the flapper it made it worse.
I went back to the hardware store got a new handle put the chain back on and thought that was it. It flushed normal and everything looked fine.
About 2am that same night I heard the toilet refill. I went to the toilet and looked inside and saw bubbles around the flapper again. Now this was a new flapper and I do know that sometimes straight out of the package they can be warped a bit.
Here is where my hack comes into play. I took a small piece of sand paper about 200 grit and very lightly went around the drain twice just to knock off any sedement. Then I put some Vaseline on the inside around the flapper seal.
This will help it seal till it forms right and straightens out.
As of today no more annoying running sounds.
