Fixing a slow running toilet

Another common toilet problem is if your toilet keeps running constantly after flushing. This usually happens because the flapper isn’t sealing correctly over the flush valve.

If you’re in a tight spot, these steps may help stop any leaking from the tank to the bowl or consult a trained plumber:

1. Empty the toilet cistern. Locate the water valve that can be usually found behind the toilet at the base of the wall and switch the water off.
2. Flush the toilet and hold the handle down so it drains fully.
3. Remove the old flapper from the overflow tube and unhook the chain from the flush handle arm.
4. Clean the flush valve seat (where the flapper sits) and remove any hard water stains to ensure it is smooth. If you don’t, it may not create an effective seal.

5. Reattach the new flapper on both sides of the tube and attach the chain to the flush arm handle.

Always consult a professional if you’re unsure of the steps. Understanding what is inside your tank can make it easier to navigate your way around it. Read our article on how to clean a toilet tank to keep it in tip-top condition.
