Use an AI assistant as your diagnosis partner before you touch a single tool.

- Phone camera
- 1
Photograph the problem
Take 2–3 clear photos: the tap from the front, underneath, and a video of the drip. Note the brand name if visible.
- 2
Ask for a diagnosis
Prompt: "My [brand] tap drips from the spout even when fully closed. Here are photos. List likely failed parts in order of probability and what each part costs in India."
- 3
Get a parts list and video shortlist
Follow up: "Give me exact washer/cartridge sizes to check with a ruler, and search terms to find tutorial videos for this exact model."
- 4
Buy right, fix once
With the AI's parts list, buy the correct size at any hardware shop (₹10–₹50). Follow the recommended video while replacing.
EFFICIENCY NOTE: Skips the classic 2-trip hardware-store mistake of buying the wrong washer.

The Worksheet
— for your hands · craft · patience
The classic method: shut off, disassemble, identify, replace. Takes one evening.
Materials
- Adjustable wrench
- Flat + Phillips screwdrivers
- New washer set (assorted, ~₹100) or cartridge if it's a mixer tap
- Cloth + old towel
- White vinegar (for crust)
- 1
Shut off the water
Close the angle valve under the sink (or the main valve). Open the tap to release pressure. Stuff the drain with a cloth so nothing falls in.
- 2
Open the tap head
Pry off the decorative cap, unscrew the handle, then loosen the packing nut / flange with the wrench. For mixers, unscrew the cartridge cap.
- 3
Identify the culprit
Pull out the spindle/valve. If the rubber washer at the end is cracked, flattened or hard — that's your leak. Crusty white buildup? Soak in vinegar 15 min.
- 4
Replace and reassemble
Swap the washer (match size exactly), smear a tiny bit of petroleum jelly on it, reassemble in reverse order. Turn water back on slowly and check.
OLD-HAND TIP: Drip from the spout = washer or cartridge. Drip from the handle base = O-ring. Diagnose before you buy anything.
