Blocked Drain Clearance in Swindon

A sink that drains slowly, water backing up into a shower tray or a bad smell from a plughole can all point to a blockage in the drainage pipework. Our blocked drain clearance service helps homes and businesses in Swindon find where a blockage is and clear it, so wastewater can flow away properly again.

Blocked drains are not always where they first appear. A blockage can sit in a sink trap, inside a waste pipe, or further along the drainage system outside the property.

Signs of a Blocked Drain or Waste Pipe

The earliest sign is often water draining away more slowly than usual. Other signs include gurgling sounds from plugholes, water rising in a shower tray or bath when other fittings are used, unpleasant smells from sinks or gullies, and water collecting around an outside drain.

If several fittings drain slowly at the same time, the blockage may be further along the system rather than in a single waste pipe. A blockage that affects only one sink is more likely to be close to that fitting.

Repeated blockages in the same place can indicate a build-up inside the pipework, a poor fall on the pipe, or something lodged that has not been fully cleared before. If this sounds familiar, our guide on why a drain keeps blocking after being cleared explains the likely reasons.

Common Causes of Blocked Drains

Kitchen Sinks and Waste Pipes

Fats, oils and grease poured down the sink cool and harden inside pipes. Combined with food scraps and coffee grounds, they gradually narrow the pipe until water can barely pass.

Bathroom Drains

Hair, soap residue and toiletries are common causes of slow-draining basins, baths and showers. They often collect in traps and the first section of waste pipe.

Outside Drains and Gullies

Leaves, soil and debris can build up in outside gullies and drains. Items that should not go down drains, such as wipes, can also cause blockages further along the system. Our article on the most common causes of blocked drains looks at these in more detail.

Inside Your Property or the Public Sewer?

Responsibility for drains depends on where the blockage is. Thames Water explains that property owners are responsible for drainage pipes within their boundary that serve only their property, while it owns and maintains public sewers, including pipes shared with neighbours.

That means a blocked sink trap, waste pipe or private drain serving just your home is normally yours to sort out. A blockage in a shared drain or public sewer should be reported to Thames Water. Our drain clearance work covers waste pipes and private drainage, not public sewers.

If you rent your home, tell your landlord or managing agent about the problem as soon as possible.

How Blocked Drains Are Cleared

A plumber will usually start by working out which fittings are affected and where the blockage is likely to be. Traps under sinks and basins can often be removed and cleaned, and blockages in short sections of waste pipe can be cleared with hand tools such as drain rods or plumbing snakes.

Where a blockage is further along the drainage system, access points such as rodding eyes or inspection chambers may be used. Some blockages need specialist drain equipment beyond what a plumber carries, and you should be told if that is the case.

Avoid pouring strong chemical drain cleaners into a blocked pipe. They can damage some pipework, may not clear the blockage and can be hazardous to anyone who later works on the pipe.

Drain clearance is one of the plumbing services in Swindon we offer for homes and businesses. If wastewater is overflowing inside a property, our emergency plumbing page explains what to do first.

What Affects the Cost of Drain Clearance?

The cost depends on where the blockage is, how severe it is and how easy it is to reach. Clearing a blocked basin trap is usually quicker than clearing a blockage deep in an outside drain. Repeated blockages may need more investigation to find the cause.

Ask what the work includes before it begins, and whether any further work is recommended to stop the problem returning. Our guide on when to call a plumber for a blocked drain can help you decide whether a problem needs professional help.

Blocked Drain FAQs

Common questions about blocked sinks, waste pipes and drains.

What causes a blocked drain?

Common causes include fats and food waste in kitchen drains, hair and soap in bathroom drains, and leaves, soil or wipes in outside drains.

Why does my drain keep blocking?

Repeated blockages may point to a build-up inside the pipe, a damaged or poorly laid pipe, or a blockage that was not fully cleared. Investigating the cause helps prevent it coming back.

What are the signs of a blocked waste pipe?

Slow draining, gurgling noises, bad smells and water backing up into another fitting can all indicate a blocked waste pipe.

When should I call a plumber?

Call a plumber if water is not draining at all, more than one fitting is affected, wastewater is coming back up, or the blockage keeps returning.

Who clears a blocked public sewer?

Blockages in public sewers or drains shared with neighbours are the water company’s responsibility. In Swindon, these should be reported to Thames Water.

How can I help prevent blocked drains?

Put fats, oils and food scraps in the bin, use plughole strainers, and only flush toilet paper. Keeping outside gullies clear of leaves also helps.
