Hello,
Today I had used a plunger on the 2nd floor toilet and and after I did when I flush the toilet you hear a knocking sound which sounds like its behind the wall or under the floor. I have never heard this sound before. I don't hear on the initial flush as the water goes down but it seems to start as the toilet tank is filling up and the knocking sound stops when the tanks is filled. With this toilet recently I always have had to turn off the shut off value after I use it and on when I use it because it slowly leaks.
Any help or suggestions would be great.
Thankyou
