25 free DIY guides · 41 total

From a dripping kitchen tap that won't stop to a bathroom mixer with no pressure, tap problems are almost always fixable without replacing the whole fitting. The most common culprits are worn washers, failed cartridges, seized ceramic discs, and limescale build-up — all straightforward DIY jobs if you know where to look. These guides cover all UK tap types including quarter-turn monobloc mixers, traditional pillar taps, thermostatic bath taps, and popular brands like Grohe, Hansgrohe, Bristan, Franke, and Quooker — with step-by-step diagnosis so you buy the right part first time.
