WANHAI 30D-11 Mixer Tap Cartridge — 30mm Replacement Valve with Flat Bottom

Features

Featuring a standard 30mm barrel diameter and a flat-bottom base, it is engineered for monobloc mixer units that require this specific profile. If your tap lever has become stiff, squeaky, or is leaking from the spout, replacing the internal ceramic disc cartridge is the most effective, budget-friendly repair.

Details

A dripping or stiff mixer tap disrupts your daily routine. Many people replace the entire expensive tap, which requires awkward under-sink plumbing work. Usually, the internal ceramic disc cartridge causes the problem. It wears down or gathers limescale over time. Unfortunately, the market sells dozens of cartridge sizes like 25mm, 35mm, or 40mm. Even with the same diameter, the footprint—the pins and bottom shape—often differs. Buying the wrong size leads to leaks or a cartridge that refuses to seat correctly.

Fortunately, this WANHAI 30D-11 mixer tap cartridge solves these issues cheaply and quickly. First, confirm the “30D-11” code on your existing unit. Next, compare the pin layout with our dimension images to ensure a perfect fit. Once you install it, you will notice an immediate difference. Your tap lever will move with ease. Furthermore, the annoying drip will vanish, and the water flow will feel smooth again. Consequently, this simple fix extends the life of your existing brassware without professional help.
