What toilet flushing problems our plumbers can solve

Half full flush not working

Dual flush systems are mandatory in Singapore due to their water-saving benefits. Sometimes, these systems may fail to properly engage the half or full-flush because of wear of the mechanism's floats or levers. Flush valves usually cannot be repaired, because its parts cannot be purchased individually. Replacing the flush valve will solve this problem.

Weak or partial flush

Weak and partial flushes are usually caused by a broken float within a gravity-operated flush valve that is allowing the flush plunger to come down before the set flush volume has been reached.

Some more expensive flush systems use siphonic flush valves. Normally, the siphon works by creating a continuous flow of water, which maintains a vacuum and draws more water after it to flush the toilet. However, a broken valve may allow air to enter the system and disrupt the vacuum, causing the siphoning to stop and end the flush prematurely.

Ghost flush

Ghost flushing, also known as phantom flushing, happens when a toilet flush plunger or flapper is no longer creating a watertight seal at the flush outlet, causing water to leak into the toilet bowl when the toilet is not flushed. When the water level in the cistern falls below a certain level, the fill valve activates and tops up the water in the cistern, this process can sound like a short "ghost" flush.

Running toilet

A running toilet happens when it has a broken fill valve that continues allowing water to enter the cistern after the fill height is reached.

Forever flush

A forever flush happens when the flush plunger does not come down to seal the flush outlet after a flush, causing the toilet to keep flushing for as long as the plunger remains up. It can also be caused by a weak siphon pulling water out of the cistern at almost the same rate it is being refilled.

Whistling tank

A whistling tank is caused by a fault in the fill valve. Fill valves that are not working optimally can produce a whistling noise that can signal an impending problem with the toilet flush system.

Slow fill

A slow filling tank is usually indicative of a clogged or damaged fill valve. Over time, debris or mineral deposits can obstruct the valve, reducing the rate at which the tank refills. Replace the fill valve or ball valve would usually restore the normal fill speed.

Leaking tank

Water can leak from the cistern tank because of cracks in the cistern or a failed seal at the rubber gasket between the cistern and the toilet bowl. Depending on the source and severity of the leak, it might require sealing the crack or replacing the gaskets.

Faulty flush button

A faulty flush button can arise from mechanical failure or alignment issues, which prevent it from effectively triggering the flush mechanism. Repairing or replacing the button assembly typically solves this problem.
