toilet leaking

If you believe that the water line to your toilet has sprung a leak, but you’re not sure how to confirm it, then here are some helpful tips on what you need to do.

Drop a dye tablet into the tank of your toilet and then wait for about 15-20 minutes. Then, when you return, check the toilet bowl and not your tank. If you notice that the toilet bowl contains colored water, then you likely have a leak on your hands.

There are other methods of determining if there is a leak in your water line. You want to check if your water level is above the overflow pipe in your tank. If this is the case, then you likely have a defective fill valve. If water is trickling down into your toilet bowl without you flushing it, then you have a leak in your water line. Another indicator of a leak is when your toilet makes a lot of noise when you are not using it (it sounds like running water).

Finding the Leak

You have now confirmed that there is a leak in the water line connected to your toilet, but now you need to locate it. The severity of the leak can determine the difference between repairing it or investing in a new water line installation. If there is a hole in the fittings, then you will need to replace your water line, because otherwise, you could easily fix the issue.

Tightening Your Fitting

Sometimes the leak is a result of a loose fitting, and you can usually fix this by tightening the fitting. You can tighten it with a small pipe wrench and we recommend that you are careful while doing this. If the leak is fixed, then you are done, but if not, then you need to do a little more investigating.

Bad Washers

If the tightening didn’t work, then that means you could have defective washers. You will need to locate your shut-off valve and turn off your water supply. Next, you will need to remove the line that connects to your toilet and water supply. He washers are found in the area where the fittings are located and they are made of a rubber material. You can then replace the rubber washers and then re-attach the water line. You can then turn on your water supply again, and if the leak persists, then you will need to take things a step further.

Applying Plumbers Tape

This kind of scenario is your last resort. You will need to acquire plumbers tape and wrap it around the fittings that connect your toilet and water supply. Also, the leak could be due to worn out threads in your fittings and the tape will help fill in those gaps. You should also do these when you replace your washers.

Repairing Major Leaks and Replacing Your Toilet’s Water Line

Although you can repair minor leaks without professional help, we recommend that you hire a well-trained plumber to handle any major damage. They will inspect your entire system and they can easily access those hard-to-reach places. They will assess the damage and determine the severity of the leak. If the repair is going to be extremely expensive, then we recommend that you replace and install a new water line altogether. This will ultimately benefit your long-term finances by limiting repairs and simplifying maintenance and cleaning services.

If you have repaired several leaks over the years and the problem persists, then replacing your water line might be in your best interest. If a pipe were to burst underground, then you will have no choice but to install a new water line. The last thing that you want to do is place a band-aid on a much more serious issue.
