Can you do a double wax ring on a toilet?

Can you do a double wax ring on a toilet?

You can certainly install a toilet with multiple wax rings, in fact sometimes it is necessary to make sure you don’t have a leak. You can buy an extra-thick wax ring, or you can just buy two rings and stack one on top of the other.

Why would you need an extra thick wax ring?

Besides diameter, thickness is also an important parameter when it comes to wax rings. Again, there are two possibilities: regular and extra thick. The wax ring forms the seal between the toilet and the waste pipe, so to determine the wax ring size, you have to remove the toilet.

Why does a toilet still leak after putting a new ring on it?

A: The most likely cause is that the wax ring around the closet flange is leaking, allowing a small amount of water to seep from under the toilet with each flush. The wax rings are probably misaligned. The fix is to reseat the toilet using a flange extension and one wax ring.

Why does my wax ring keep failing?

What causes toilet wax rings to fail? First and foremost, a loose toilet will often cause a wax ring to lose its seal and leak. Next, in the event that you have to replace your toilet, your wax ring will lose its seal, so you’ll need to install a new one along with your new toilet.

Is it OK to stack wax rings?

Do not be tempted to stack up two wax rings because this setup tends to leak. Installing a flange extender or using an extra-thick wax ring will work much better in the long run. Place the wax ring on the closet flange, not on the toilet.

How do you know if your toilet wax ring is bad?

The telltale sign of wax ring failure is water leaking out from around the base of the toilet. You might also notice a toilet feeling unusually wobbly if the wax ring is coming loose.

How many wax rings does a toilet need?

Two Wax Rings
Installing Two Wax Rings Place the toilet on the flange and push down firmly to compress the wax. Tighten the bolts, hook up the water and give the toilet a few test flushes to make sure it isn’t still leaking. A toilet bowl is heavy, so you may wish to have an assistant help you to position the bowl over the flange.

Does a wax ring only leak when flushed?

The only-when-flushed toilet leak could be caused by loose mounting bolts or a worn-out wax gasket while the all-the-time leak could be caused by a loose water supply line connection, a problematic water shutoff valve, or a faulty seal between the toilet tank and its base. Your toilet could have a damaged wax ring.

How long should a wax toilet seal last?

A wax seal will often last the life of the toilet, 20 or 30 years, without needing to be changed. There are times, though, when the wax ring will need to be replaced.
