Blocked Bath & Shower Drain in Sheffield

Hair and Soap: the Usual Suspects

Most blocked baths and showers come down to hair and soap residue. Hair sheds naturally in the shower and collects in the drain cover and the trap beneath it — a combination of long hair and soap creates a felt-like mat that water cannot pass through. Clearing the drain cover screen regularly helps, but the hair that passes the cover accumulates in the trap and pipework below it.

Soap residue compounds the problem. Soap leaves a sticky film on the inside of the drain that catches hair more effectively and narrows the bore over time. Together they create a blockage that a plunger alone cannot shift — the clog needs to be physically removed from the trap or cleared with a jetting lance.

Limescale: Sheffield's Hard-Water Problem

Sheffield is supplied with hard water. The Pennine reservoir system draws water through carboniferous limestone, picking up dissolved calcium and magnesium bicarbonate. When this water is heated — in your hot water cylinder, boiler, or shower — the calcium deposits out of solution as calcium carbonate: limescale.

Inside a bath or shower drain, limescale builds up gradually on the inner surface of the pipe, narrowing its effective bore. A drain that was installed at the correct minimum diameter becomes, in effect, an undersized pipe — and blockages occur more readily. This is a slower process than hair accumulation but the result is the same: a drain that won't clear properly.

Where we find significant limescale build-up, we carry out descaling as part of the same visit — removing the mineral deposits and restoring the full bore of the pipe. See our drain descaling service for more.
