How to Prevent a Running Toilet and Water Overflow - 4D Heating and Plumbing

One of the common problems in most houses these days is a running toilet along with waste of fresh water that causes great annoyance to everyone. Thankfully, addressing this issue has become quite easy that will help to lessen use of water. Let us begin with a simple lesson related to the mechanics of maintaining a toilet so that you may not suffer from unnecessary problems.

How your toilet works

  • On pressing the handle, there is a chain that lifts the flapper and allows water to flow into the bowl. When the tank gets empty, the flapper drops and then closes the opening for starting refill cycle.
  • There is a big plastic float that drops when water empties out of the tank. The float is then connected to the valve that opens when float is down and closes when float is up and the tank is full.
  • You will find an overflow tube at the center of the tank that drains away excess water into the bowl when the level in the tank becomes high. This tube is the channel with which float valve sends water to the bowl at the time of refill cycle.

A toilet that tops up the tank or a constantly running toilet may occur due to several problems such as – a high water level, a water-logged float or a faulty flapper. The best solution is to get it replaced as soon as possible.

How to check for a faulty chain or flapper

How to adjust the level of water

The overflow tube of the toilet ensures the tank may not overfill and flood the washroom. But if the fill valve’s float has been set extremely high, then small amount of water can cause leakage into the overflow tube and the bowl thus, leading in the fill valve to turn on automatically and top up the tank periodically.

  • Lower float setting on the valve – There are certain valves that have a metal rod and small clip to slide the float up and down on the rod as well as move clip down to lower the level of water. If you have an old valve with a tank ball and a long rod, then bend the rod carefully at the middle so that the ball goes a little deeper into the tank.
  • Flush the toilet properly – It is necessary to flush toilet properly so that it refills and then stops by itself.
  • Check the level of water – This should be at least 1/2 to 1 inch below the top of overflow tube.
  • Try to adjust with the float – Adjust the float as much as possible and flush again till the refill stops at a proper level.

How to detect a water-logged float

Water-logged floats may be the reason for a constantly running toilet. When the water gets trapped into the float, it will reside lower and leave float valve partially open. It is important to check your float by unscrewing it and then shaking it. Your plumber in London will replace the float when you hear there is water inside.

How to replace a fill valve

Your fill valve will keep a control of the flow of water in the toilet tank. In case there is a broken valve, then this may fail to shut off thus, causing non-stop or unintended refill cycles. Submerged float valves are a common sign of faulty fill valve as they can be replaced easily and are inexpensive. Hence, it is always better to replace an old fill valve than to get it repaired.

The steps to follow

  • You need to turn off water supply by closing shutoff valve on the pipe that lead to the toilet. After this, remove tank lid and flush toilet properly to empty the tank.
  • Place a bucket or plastic bin, just below the water supply hose. After this, disconnect supply hose from the bottom of the fill valve.
  • Remove fill valve by unscrewing locking nut on the bottom of water supply shank and then pulling the valve out of the tank. Residual water present in the tank will be draining into the bucket.
  • Try to adjust height of new valve so that it fits tank’s height and follow the instructions of the manufacturer. After this, insert threaded end of the valve in the tank’s hole and secure with a locking nut. Choose pliers to turn the nut and form a watertight seal. Make sure you do not over-tighten it.
  • Attach supply hose to fill valve and then tighten it with pliers. Clip valve’s refill hose at the top of overflow tube so that the hose points down into the tube. Try to avoid placing tube below the water line as this can cause constant refilling. Most valves have an angle adapter or a clip that ensures the tube is at the right angle.
  • Turn on water at shutoff valve and allow the tank to refill. After this, tune water level, as required so that the water stops nearly 1 inch below the top of the overflow tube or as directed by the manufacturer. Replace the lid of the toilet tank.
