Troubleshooting a Toilet That Is Leaking From the Base

Troubleshooting a Toilet That Is Leaking From the Base

There is nothing more annoying than a toilet that leaks water, and troubleshooting a toilet leaking from the base is something that cannot be done in a few minutes. You will need to take the time to work out how to spot where the leaks come from, and you will also need to learn how to fix that problem once you have found it.

There are several reasons why a toilet might leak from the base, and being able to spot the difference can help you to get the best from your toilet.

Cracks in the Toilet Bowl

Cracks in the fabric of the toilet bowl can often cause it to leak around the base. Water being flushed away from the bowl will run out of the crack, forced by water pressure, and this will form a pool around the base. If this is the cause of the problems, then you will need to empty the bowl of water, and then use some water-proof glue or sealant to fix the crack. The sort that is suitable for sinks and baths will be perfect for this. Leave to dry.

If you find that you are still having problems with your bowl leaking, then you may need to replace it entirely.

Problem With the Wax Seal

The base of your toilet is water sealed using a wax ring. Sometimes, if you have had recent plumbing done, or you have altered the sub-flooring, the drain can take longer to work, meaning that water will sit around the wax ring. If the ring is slightly loose, this water will then seep out around the base.

Toilet Not Firmly Fixed

Toilets are fixed to the floor using a pair of bolts which you can see on the side of the toilet bowl. Close them up tightly, and you may find that water stops leaking from the base. Tighten both of the bolts, not just one, in order to ensure that the bowl is properly fixed to the floor.

Leak Coming From Elsewhere

If you cannot find a solution to your problems through these solutions, then you should consider that the problem might be coming from elsewhere. Water can flow down from something like a leaking tank, and then escape around the base. The bolts that secure the tank to the toilet bowl are one source of leaks, as is the gasket underneath that bowl. These can be easily fixed by removing the bolts and replacing, or tightening them where they are in the location. Use a screwdriver, and screw from the inside of the tank down. This will allow a better seal.

Troubleshooting a toilet that is leaking from the base may be time consuming, but seeing if it is an easy fix can save you big. Happy plumbing!

Repair a Running Toilet

A running toilet is a nuisance. However, fixing it doesn’t have to be. You’ll save money on you water bill and on a plumber by fixing it yourself. Use this guide to find, and fix, the source of the problem.

Check the Guide Rod (or Chain)

If the rod is bent or the chain links are twisted, just straighten them.

Check the Float Mechanism

If lifting the ball up stops the water from running, try to bend the float arm down to get the right buoyancy. If you notice that the ball has water in it, it needs to be replaced. Replace it by unscrewing it from the arm and putting a new one in its place.

Check the Valve Seat and Stopper

If the toilet is still running, the valve seat and stopper may have corrosion or build-up preventing the stopper from closing. Lift the stopper up and check for any objects. Gently scour the seat and the rim. If there is a great deal of damage, replace the stopper and valve seat.

Check the Flush Valve Assembly

It may have to be replaced if the toilet is still running. Take the old parts with you when purchasing new inside gaskets and assemble to ensure a perfect match. If the shaft of the assembly is cracked, the whole shaft and assembly will need to be replaced. Again, take the flush valve assembly with you to get a perfect match.

Now that you’re toilet is no longer running, you’re water meter won’t be either! You saved big by repairing this yourself.

Repairing a Leaking Toilet Water Supply Line

There are several reasons why a toilet water supply line would leak. It could be a hole in the line or worn out treads in the connection. Troubleshooting this problem is the first step to fixing it. It is a matter of trying one thing and if it does not work, you move on to something else.

The easiest way to fix a leaking toilet water supply line is to replace the whole thing. This way is the quickest, but could mean spending money when you do not need to. Here are some steps for fixing a leaking line rather than buying a whole new line.

Step 1 – Find the Leak

First, you will need to determine where the leak is coming from. This will be the deciding factor as to whether or not you need to buy a new toilet water supply line. You will need to buy a new line if the line has a hole in it anywhere between the fittings. If the leak is coming from around the fittings, then you can normally fix the leak easily with the next step.

Step 2 – Tighten the Fitting

If the leak on your toilet water supply line is coming from around the fitting, it can usually be fixed by just tightening the fittings a little tighter. You need to take your small pipe wrench place it on the fitting and very gently tighten the line. If the leak stops, you are done. If not, move on the the next step.

Step 3 – Checking the Washers

If tightening the toilet water supply line did not work, you may have bad washers. You need shut the water off at the shut off valve. Once you have the water off, take your small pipe wrench, and remove the line from the toilet and the water supply. There will a rubber washer in each fitting. Remove the washers and replace them. Reattach the line. Turn the water back on and check for leaks. If you still have a leak move on to the next step.

Step 4 – Putting on Plumber’s Tape

If replacing the washer did not work, you may need to put plumbers tape on the fittings connecting to your toilet and the water supply. Remove the line just like you did in step three. Wrap the tape around the treads of the fitting on the toilet and the threads that attach to the water supply. The leak may be from worn treads on the fittings. The tape will help fill in the gap. Replace the toilet water supply line and check for leaks. You may choose to do this at the same time you replace the washers.

If you have gone through these steps and still have a leak, you will need to buy a new line.

Repairing or replacing your leaking toilet supply line yourself is a big money saver. Enjoy the satisfaction of a job well done1
