Water use and noise
Older single flush cisterns use 9 to 12 litres per flush, while dual flush systems use 3 and 6 litres. Quiet fill valves reduce refill noise. Water saving matters where supply is limited.
Common faults
- Running water. Worn flush valve seal or float set too high.
- Weak flush. Low water level or blocked rim holes.
- Slow refill. Blocked fill valve filter or low supply pressure.
- Stuck button. Misaligned rod or worn parts.
Repair first
Most problems are fixed with a repair kit costing PKR 1,300 to 1,500. Close the supply, drain the cistern, replace the valve or seal and test. Replace the whole cistern only if it is cracked.
Replacement and compatibility
Flush valves must match the cistern hole and height. Take the old part to the shop. Buying a known type ensures spares later.
Fitting
Turn off the angle valve, drain the cistern, fit the new part, adjust the water level and test several flushes. Fixed plumbing should be done by a licensed plumber.
What to check before buying
- Type. Matches the cistern
- Flush volume. Dual 3 and 6 litres
- Spares. Available locally
- Quality. Brand fill and flush valves
Water saving
Fixing a running cistern can save hundreds of litres a day. Check for faint trickles by adding food colour to the tank and waiting 15 minutes.
Before you decide
Identify the fault, try a repair kit first and choose a dual flush when replacing. A well tuned flush system is quiet, strong and saves water.
