The Common Leaking Toilet Problem

You would think that after a couple of hundred years and multi millions of installations around the world, that manufacturers would have a rock-solid toilet design that doesn’t leak. But as we all know they haven’t.

Not for lack of trying – there have been developments from basic floating ball valves to sophisticated multi shut-off valve models, but to no avail. Leaking toilets (followed closely by blocked drains) are the number one reason that people call a plumbing contractor.

You probably know the symptoms, after flushing the toilet, water keeps running and doesn’t shut off. Often it is just a small amount and easy to ignore, but you would be surprised how much water can be wasted by a leaking toilet, and you can end up paying the Plano water department a far larger amount for your monthly water bill than you need too. Imagine just leaving a garden hose turned on slightly 24 hours a day and you can get an idea of how much it can cost if not repaired promptly.

Repairing a Leaking Toilet

There are a few common reasons for a leaking toilet. The first is with the flapper valve. This is a rubber or soft plastic flap which is lifted up by the toilet handle to allow the stored water in the tank to flow into the toilet bowl. Sometimes the toilet handle gets worn out and the portion of the handle inside the tank causes the flapper not to return to its closed position. In most tanks there is a small chain which connects the flapper valve to the toilet handle, and this can become disconnected or twisted so that the flapper does not fully return to the closed position.

Another common issue is the flapper valve becomes hardened over time. The effects of the natural salts (and added chemicals) in the municipal water in addition to natural ageing can either build up a deposit of salts on the flapper or it can become brittle so a perfect seal with the toilet bowl is not made, leaving a small gap for water to continuously drain into the bowl.

One of the other reasons for a toilet leak is a failure in the inlet shut-off valve, again over time the float mechanism can jam or become mis-aligned, so that the valve does not shut-off when the water reaches the correct level, and again water will keep running through the overflow tube into the toilet bowl.

So now you know the possible reasons for a leaking toilet, the solution is simple. Give us a call and have one of our professional plumbers fix that leak.
