An exterior drain outside your house is typically installed to manage stormwater, prevent foundation flooding, or discharge appliance wastewater. The specific type of drain usually depends on where it is located:
Overflowing or pooling water around your drain can be a sign of a significant blockage that needs immediate attention. Before you begin attempting to clear a blocked drain, take a moment to assess the situation. Start by checking for visible signs of blockage around the drain cover.
Most storm drains simply collect rain water and channel it away to prevent flooding, carrying polluted runoff to local water resources.
A drain is a pipe that drains water and waste from a building and other buildings which belong with it, for example a garage. A lateral drain is a length of pipe which carries wastewater away from your property to a sewer. It's usually located outside your property boundary, often under a public pavement or road.
Professional drain cleaning typically costs between £80 - £120. This may sound steep but it's a worth while investment.
Drain Unblocking with a Hose
A great way to clear a blockage without using chemicals is to use a hose or pressure jet to force the obstruction through the pipe. To do this, you should first clear the drain as much as possible using your hands or tools and then scoop out the water to a manageable level.
A broken underground drain pipe typically presents with signs like sewage odors in the yard, consistently slow drains or multiple clogs, unexplainably lush patches of grass, or sunken spots/sinkholes on the lawn. Other indicators include unexpected gurgling noises from toilets and standing water in the yard.
In most cases, a clogged drain will not fix itself. While minor accumulations of soap scum may occasionally wash away with continuous water flow, most blockages—such as trapped food, hair, or grease—will simply get worse and completely block the pipe without manual intervention.
Vent pipes, typically PVC, release sewer gases and regulate air pressure in the plumbing system, preventing blockages. Rodents are adept at squeezing through tight spaces, and pipes offer ideal pathways.
Unless your house is on a combined drains system, it needs separate drain connections to collect wastewater and rainwater.
For most yard drainage problems, your first call should be to a local yard drainage contractor or landscaping company with drainage expertise, not a plumber or general contractor.
Property owner's responsibilities
The drains which carry household waste are normally the property owner's (or the landlord's) responsibility up until the boundary of the property where they connect to public sewers. There will often be a company maintained manhole at that point.
Pouring salt down your drain at night is a popular DIY plumbing trick used for routine maintenance. The goal is to take advantage of the salt's coarse texture and natural moisture-absorbing properties.
As the fall rains intensify and the seasons shift, one surprising tip is getting renewed attention: pouring vinegar down your drains to help prevent clogs.
A straightforward yet effective approach to addressing a clogged drain pipe involves simply using hot water mixed with dish soap. This method, ideal for tackling minor blockages, leverages the degreasing power of dish soap combined with the force of hot water to dislodge and dissolve clog-causing residue.
Yes, pouring boiling water down a drain can help, but only for minor clogs (like light soap scum or fat) and only if you have metal pipes. For PVC or plastic plumbing, boiling water can soften, warp, or melt the pipes and their glued joints.
Rats are a primary food source for a wide variety of animals. Their most significant natural and artificial predators include:
The Amish control mice through non-chemical, self-sustaining methods, relying on active trapping, natural scent repellents, and structural exclusion. Rather than using commercial poisons, they focus on physical barriers and natural predators to keep rodent populations in check.
Here's the reality: if you see one mouse during the day, there are likely 5-10 more you're not seeing. In other words, daytime sightings almost always indicate multiple mice. Even nighttime sightings suggest more than one. Mice are social animals that live in family groups.
Prices start from approximately £90 for straightforward manual unblocking to £275 for a complete CCTV drain assessment including a detailed report. Additional services such as high-pressure water jetting and drain relining are charged per service or per linear metre. Drain relining averages at £100 per linear metre.
How to unclog a drain
If it's within your internal pipework, you'll need a plumber. If the blockage is within your property boundary, on a drain or sewer only serving your property, you'll need a drainage contractor. Both can be found on a reputable site such as checkatrade.com.
A sewer line that is breaking shows 4 early warning signs. Common signs include sewer gas odors near drains, repeated clogs and backups, mold or damp spots inside, and unusually lush or soggy areas in the yard along the pipe route.
There are two main methods for a drain test; the air test and the water test. Other methods include smoke testing and the mandrel testing method. All of the tests are conducted to ensure that the newly installed plumbing system is free of leaks and is up to standard.
Plumbers have several tools and methods at their disposal for underground water leak detection and pinpointing the exact location of any leaks. This includes acoustic listening devices, soil probes, thermal imaging and pressure testing.
