🚰 Types of Kitchen Taps

Different tap types have different repair methods for a leaking kitchen tap:

• Compression tap (two-handle): Old style with separate hot/cold handles. Uses rubber washers. Common in older homes. Easiest to repair.
• Ceramic disc tap (mixer): Single lever, modern design. Uses ceramic cartridges. Very durable but cartridges are more expensive.
• Pull-out/pull-down spray tap: Single lever with spray head. Has additional hose connections that can leak.
• Touch/sensor tap: Electronic activation. More complex repairs—call a professional.

How to identify your tap type: Two handles = compression. Single lever that moves left/right and up/down = ceramic disc mixer.

For most modern kitchens, you have a ceramic disc mixer tap.

💧 Fix #1: Leaking from the Spout (Dripping)

Cause: Worn cartridge (ceramic disc taps) or worn rubber washer (compression taps).

For ceramic disc mixer taps (most modern kitchens):

1. Turn off water supply under the sink (isolation valves).
2. Remove the handle screw (under a decorative cap).
3. Lift off the handle.
4. Unscrew the retaining nut (may need a special tool).
5. Remove the old cartridge.
6. Take the cartridge to the hardware store to match.
7. Install new cartridge (apply silicone grease to O-rings).
8. Reassemble in reverse order.
9. Turn water on and test.

For compression taps (two-handle, older style):

1. Turn off water supply.
2. Remove handle screw and handle.
3. Unscrew the valve stem.
4. Replace the rubber washer at the bottom of the stem (R5-R20).
5. Reassemble and test.

Time: 15-30 minutes. Cost: R20-R200.

🔧 Fix #2: Leaking from the Tap Base

Water pooling around the base of the tap indicates a loose mounting nut or failed O-rings.

Cause: Loose mounting nut or worn base O-rings.

DIY fix:

1. From under the sink, tighten the large mounting nut (use a basin wrench if space is tight).
2. If still leaking, remove the tap, clean the base, and replace the O-rings or gasket.
3. Apply plumber’s putty or silicone sealant under the base before reinstalling.

Time: 30-60 minutes. Cost: R50-R150 for new O-rings/sealant.

🔄 Fix #3: Leaking from the Handle

Water seeping from under the handle when the tap is on indicates worn O-rings.

Cause: Worn O-rings on the cartridge or valve stem.

DIY fix:

1. Turn off water supply.
2. Remove handle and cartridge (see Section 5).
3. Replace the O-rings on the cartridge (or replace the entire cartridge).
4. Apply silicone grease to new O-rings.
5. Reassemble and test.

Time: 20-30 minutes. Cost: R20-R50 for O-rings, or R50-R200 for new cartridge.

💨 Fix #4: Leaking Pull-Out Spray Hose

If water leaks from the spray head connection:

Cause: Loose connection or worn O-ring.

DIY fix:

1. Check the connection where the hose attaches to the spray head—tighten if loose.
2. If still leaking, replace the O-ring inside the connection (R10-R30).
3. If the hose itself is cracked, replace the entire hose (R100-R300).

7. Match the cartridge – Take to hardware store. Cartridges vary by brand.
8. Install new cartridge – Apply silicone grease to O-rings. Insert in same orientation.
