How to Fix a Toilet Fill Valve

You walk in the bathroom and what do you see — a puddle of water surrounding your toilet. This puddle is commonly caused by a faulty fitting of the toilet fill valve. Fixing this problem can be as simple as following these quick steps.

Step 1: Shut off the water supply valve behind the toilet before attempting to fix the issue. You can now take the lid off of the toilet and begin the repair.

Step 2: With the water supply shut off, flush the toilet so the remaining water from the tank will drain. This will allow you to access the parts of the toilet without getting wet or having the leak continue while you work.

Step 3: Locate the toilet fill valve on the left side of the tank and grab ahold of it with one hand. With the other hand you will need to tighten the nut attaching the water line to the tank of the toilet.

Step 4: Carefully tighten this piece until it is secure. Too much tightening can cause this piece to break because it is commonly made from plastic. You can then open the water valve and fill the tank once again. Check to see if the leak still exists.

Step 5: The leak should be fixed, but if not then the seal may need to be replaced. If the toilet leak still continues after replacing the seal then the entire toilet valve should be replaced.

A toilet valve and its seal are a common reason for many toilet leaks. During your repair, if you need the help of a professional, be sure to rely on the expert technicians at Lancaster Plumbing, Heating, Cooling & Electrical. To learn more, or to schedule a repair, give us a call at (717) 207-8198.
