Let me explain how a toilet works. First when you go to flush the toilet a little arm pulls a rubber flapper up and lets the water drain into the toilet bowl. The water draining into the toilet bowl forces the old water out along with the number two or number one waste and extremities.
If the toilet sounds like it is running there is a good chance that the seal between the rubber flapper and the plastic rain at the bottom of the toilet is broken somehow. The sound you are hearing is water running around this ring and in to the toilet bowl.
This leak is actually causing no damage to the toilet itself but is wasting water. Hence the water bill will be a little higher if you don’t fix the leaking toilet. The best way to find out if this is actually your problem is to take the toilet tank lid off. Then stick your hand down into the toilet bowl and press gently on the rubber flap.
If the water stops leaking or starts running faster this is your problem. Turn the water off to the toilet. There will be a shut off valve on the wall under your toilet bowl in the bathroom. After you turn the water off removed the plastic flap and examine it.
You will be looking for a warped toilet flap or of some sort or grooves on the flapper itself. Take the toilet flapper down to your local home improvement store and buy a new one. Go home and replace the new toilet flapper and this should solve 90% of your leaking toilet problems.
There is one more thing it could be. With the toilet tank lid off, check to see if water is overflowing into the little round plastic pipe. This plastic pipe should have a small hose running from the float valve assembly into it.
If the water is over flowing from the toilet tank into this little plastic pipe you will need to adjust the float.
First thing you will need to do is while the toilet is running lift up on the float lever arm. If the water stops you can simply bend the metal arm of the float lever. The purpose of bending the arm will force the float deeper into the water there for stopping the water from rising over the small tube in the center of your toilet.
There are few parts to a toilet and most parts can be purchased at your local hardware or home improvement centers. Toilet Repair Massapequa NY like this can be made simple and the parts used to replace are inexpensive.
