Blocked Sink in Wolverhampton — Kitchen & Bathroom Clearing

Kitchen Sink Blockages

Kitchen drains accumulate grease, fat, and food debris with every wash-up. These substances do not flush cleanly — they coat the pipe walls and, as the water cools, solidify into a progressively thicker lining. In the terraced housing that makes up much of Whitmore Reans, Heath Town, and Blakenhall, the original clay or cast-iron waste pipes are narrow by modern standards. A small amount of grease build-up causes noticeable slowing, and a full blockage can develop quickly.

Running hot water down a kitchen drain can temporarily soften a grease plug and restore partial flow, but it does not remove the residue on the pipe walls. Rodding creates a passage through a solid blockage. High-pressure jetting does both — it clears the obstruction and simultaneously scours the pipe walls clean, removing the greasy lining that would otherwise cause the problem to recur within weeks.

Bathroom Sink Blockages

Bathroom basin blockages are almost always a combination of hair and soap scum. Hair accumulates in the trap beneath the basin — the curved section of pipe designed to hold water as an odour seal — and in the first section of pipe beyond it. Soap dissolves partially and leaves a sticky residue that binds hair into a solid mass.

In Wolverhampton's hard-water supply area, soap reacts with the calcium and magnesium in the water to form an insoluble soap curd — a waxy, grey residue that is far stickier than ordinary soap scum. This compounds with hair and limescale on the pipe walls to create a blockage that forms faster and is harder to shift. The trap beneath the basin is the first place to check. If the blockage is deeper in the pipe, mechanical clearance or jetting is needed.

When It Is a Bigger Problem

If multiple sinks are draining slowly at the same time, or water is backing up in a ground-floor drain or toilet when you use an upstairs sink, the blockage is not in the individual trap. It is in the shared drain below the fixtures, where waste from several appliances converges before connecting to the main sewer. This is a drain engineer job, not a simple sink unblock — it typically requires jetting the shared run rather than clearing individual traps.

We diagnose on arrival and will tell you clearly what is blocked and what it will take to clear it before any work begins.
