why does my toilet not flush properly

If the flush lever doesnвt work at all, there may be one of two problems with your toilet. If the tank is empty, the toilet will not flush. The tank is filled with water from the supply line running into your toilet tank. The valve for this is usually on the wall behind the toilet bowl. Make sure the valve is open, and then check inside the tank to make sure the float is not stuck or obstructed. The second issue may be that the chain connecting the flush lever to the flapper is broken or too loose. This prevents the flapper from opening and closing, and this prevents the toilet from flushing. Check the chain or wire that connects the lever to the flapper.


If it is a chain, remove some links to tighten it, or replace it if the chain is too tight. If the lever is connected with a wire, loosen the screw on the lever arm and adjust the length of the wire.
My Toilet Wont Flush! A very frequent problem in homes is the loo not flushing properly. If the toilet worked properly and then stopped flushing despite how vigorously the handle is pulled, there are only two probable answers: A cistern allows water in through a valve located just inside the cistern. There are two main types of valve. One, the most common, is the ball valve.


You can get a ball valve repair kit here. The second, ever more widely used is the quieter Torbeck valve. Both operate on the same principle. The water inlet is controlled by a valve which is opened and closed by a lever. The lever or БFloat armБ is raised and lowered by the water in the cistern (this is exactly the same system as that used in cold water tanks in most lofts). Once the water is in the cistern, a flushing mechanism lets it out again. The most popular flushing mechanism is the toilet siphon. The handle is attached, via a wire, to the top of the flush siphon. When the lever is depressed, or the chain pulled, the flush diaphragm is pulled upwards on the diaphragm frame.


Because of the frame underneath the flush diaphragm the water cannot escape and is drawn up and over into the flush pipe where it runs straight into the toilet bowl. If the flush diaphragm is split however, the pressure of the water as the diaphragm is drawn up the chamber, simply pushes through the split and does not allow any resistance. The more you flush, the bigger the split gets. Time to change the diaphragm! A split diaphragm can be replaced by turning off the water to the cistern, flushing the toilet and soaking up any remaining water with a sponge.


Once the cistern is empty, unclip the connection between the handle arm and the flush unit. Release the back nut under the cistern and pull the flush unit clear. Unclip the bottom half of the connection clip and pull out the frame which holds the diaphragm. (There may be a spring over the central dowel, donБt forget to return this when re-assembling) Unclip and slide off the diaphragm, replace and re-assemble. Take a look at our video sections on and also our section on to watch a couple of films that deal with a toilet not flushing and an overflowing toilet.
