Solihull: a dripping kitchen tap fixed with new hot and cold cartridges, no new tap needed
A two-lever kitchen mixer tap in Solihull was dripping. We took the tap apart and found the old cartridges worn and corroded. We fitted new cartridges on both the hot and cold sides and put the tap back together, so the customer kept their tap.
A customer in Solihull had a two-lever kitchen mixer tap that was dripping. Inside a lever tap like this, a cartridge on each side opens and closes the water. Both old cartridges were worn, with green corrosion and scale around the brass. We replaced the hot and cold cartridges and rebuilt the tap. The drip was fixed and the tap itself stayed, so no new tap was needed.

Open doors and windows, do not switch electrics on or off, do not smoke or use naked flames, and turn the gas off at the meter if it is safe to do so, unless the meter is in a cellar or basement. Once the supply has been made safe, we can trace and repair the fault.

The problem
The customer in Solihull had a two-lever kitchen mixer tap that was dripping.
What we found
Inside a lever tap like this, a cartridge on each side opens and closes the water. With the handles off and the cartridges out, both old cartridges were worn, with green corrosion and scale around the brass. The first photo shows one still in the tap body, and the third shows an old cartridge next to a new one.
The repair
We fitted new cartridges on both the hot and the cold side and put the tap back together. The drip was fixed and the customer kept their tap. Our plumbing repairs page covers taps, toilets, showers and leaks.
Repair, not replace
A dripping tap does not always mean a new tap. When the body is sound, new cartridges are often enough. If a tap does need replacing, a kitchen tap is £200 supplied and fitted.
What it costs
A tap repair depends on which cartridges the tap takes. Send us the make or a photo on WhatsApp and we will confirm the price before anything is booked. Details are on our price list.
Common questions
Why does my tap keep dripping?
On a lever tap like this one, a cartridge inside the tap body opens and closes the water. When the cartridge wears, or scale and corrosion build up on it, it stops sealing fully and the tap drips.
Do I need a new tap if it drips?
Not always. If the tap body is sound, new cartridges are often enough, as they were here. If the body itself is corroded or the cartridges are no longer available, a new tap can be the better option; a kitchen tap is £200 supplied and fitted.
Should both cartridges be replaced?
When one cartridge has worn, the other is usually the same age. On this tap we replaced both the hot and the cold on the same visit.
How much does a tap repair cost?
It depends on which cartridges the tap takes. Send us the make or a photo on WhatsApp and we will confirm the price before anything is booked.

Water from a third-floor flat had damaged the two flats below. We were on site in 45 minutes, found a split flexi hose under the basin, and fitted a new tap and hoses the same visit.
Several engineers and a shower pump had not fixed it. The gate valve on the vented cylinder had snapped inside, turning freely but barely open. A full-bore lever valve in its place, and the tenants had proper hot water pressure for the first time in over a year.
A corroded radiator valve had started leaking onto the floor. Dust sheets down first, radiator drained, new valve fitted and checked on the same visit.
