How to Fix a Leaking Tap (Step-by-Step)
Stop drips from pillar taps and mixers at home
Updated January 2026 · 2 min read
Quick answer
To fix a leaking tap: shut the isolation valve, open the tap to release pressure, dismantle the head, and replace the worn part — a washer on traditional pillar taps or a ceramic cartridge on modern mixers. Reassemble and test. Call a plumber for sealed mixers or concealed valves you cannot access safely.
Key Takeaways
- Shut the local stop valve before opening any tap.
- Pillar taps usually need a washer; single-lever mixers need a cartridge.
- Keep the parts in order as you dismantle for easy reassembly.
- Take the old washer/cartridge to match the exact size and model.
- Stop and call a plumber if a mixer is sealed or the leak persists.
A dripping tap is one of the most common — and most fixable — plumbing issues in Mumbai homes, and left alone it wastes thousands of litres a year while staining counters and fittings. Before you touch anything, close the isolation valve under the basin (or the flat's main supply if there is no local valve) and open the tap to drain the residual water and pressure. Lay a cloth over the drain so small screws and washers cannot disappear down it.
Identify the tap type, because the fix differs. Traditional pillar taps leak from a worn rubber washer at the base of the spindle — a cheap, simple replacement. Modern single-lever mixers usually need a ceramic cartridge matched to the brand (Jaquar, Hindware, Parryware, and similar). Dismantle the handle and bonnet carefully, keeping every part in the order you removed it, and take the old washer or cartridge to the hardware shop so you match the exact size — guessing leads to a tap that still drips after reassembly.
If the tap is a sealed mixer, the valve is concealed behind tile, or the leak continues after you have changed the washer, stop and call a professional rather than forcing components. Mumbai's hard water wears these parts quickly, so recurring leaks are normal.

Frequently asked questions
Can I fix a mixer tap myself?
Simple cartridge swaps are possible if you can match the part, but sealed or concealed mixers are best left to a plumber to avoid damaging the fitting or the wall.Why does my tap still drip after I replaced the washer?
Either the washer size does not match, the valve seat is scored, or it is actually a cartridge tap. A plumber can re-seat or replace the cartridge to stop the drip.
