Toilet not flushing properly?

A normal, old fashioned toilet cistern uses too much water as it is, so when it's faulty and leaking it doesn't bare thinking about!

If you have an old single flush toilet that doesn't flush when you pull the lever you will find yourself waiting for the cistern to fill enough to have another go, and then hoping the flush kicks in to clear the toilet bowl below. Topping up the toilet tank in this way can take a while, especially if the water pressure is low, with a reduced water flow, and worse still, it can waste water. One of the main complaints we hear is about a slow flushing toilet.

The average person in England and Wales use about 150 litres per day in the home. It is estimated that this is a small percentage of the daily usage and an average person could consume over 3,400 litres per day every day. This would take into the account all the products that we consume, the cars we drive and the food we eat.

If you are looking for water saving options, with a new Dual flush, push button valve you take control back of your water consumption and lose the frustration.

Toilet flushing accounts for over 1,900 megalitres of water per day. This could be reduced to 1450m megalitres per day by 2020 if a good mix of policies are adapted.

Common causes why your toilet may not be flushing

1. If you have an old fashioned lever flush toilet, it is most likely to have a Syphon for flushing. The Syphon contains a pvc sheet called a Diaphgram and this is required to create a vacum and lift the water required for flushing, if this is split or perished, it cannot function correctly and may give a weak flush.

2. The flush handle may have worked loose from many uses and is not turning the link chain sufficiently to lift the diaghram.

3. The link between the handle and the syphon is twisted / stretched / broken and is failing to lift the syphon enough to create the vacuum needed.

4. There may be problems with the float ball, toilet flush handle, or the fill valve. It is quite easy on most toilets to take the lid off, check all the parts are joined together correctly, that nothing is bent or out of place and the water supply is providing water. Also check the overflow tube to ensure this is not clogged. If the flush level is not operating correctly you'll be able to see this with the toilet cover removed.

5. If the water level is too high or the water drains slowly, it may be blocked and will need to be unblocked. Common reasons of a blocked toilet is when items other than toilet paper is flushed. You should avoid flushing other items down the toilet, since it is bad for the environment and can also lead to issues with the toilet flush. How to unclog a toilet? The simplest and cheapest method is by using a toilet plunger which is quicker and easier than having to call the plumber to come and fix it.

The Environment Agency has developed a methodology for identifying and classifying relative levels of water stress in water company areas in England. The Government has used this map to designate areas of serious water stress for the purpose of accelerating water metering.
