Extreme weather can have a serious impact on homes, infrastructure, and plumbing. Here in west Cornwall, very high winds of over 100 mph caused widespread damage to trees, buildings, and utilities during the recent Storm Goretti. While the storm left fallen trees and roof damage in its wake, it also disrupted water supply for thousands of households.
Some of the most dramatic damage occurred at St Michael’s Mount, where reports suggest around 80% of the trees on the island were blown down. Similar effects were seen elsewhere: several large trees fell in Penlee Park, mobile homes were upended at Ashton, roofs were ripped from properties near Sennen, and in Goldsithney, trees fell on houses. Schools from St Buryan to St Ives closed due to unsafe conditions.
The storm’s force was also felt by local residents. Naturalist Steve Backshall, who lives near Land’s End with Olympian Helen Glover and their young children, described it as “like on the bridge of a ship in the Antarctic.” Several windows were blown in, and the roof seemed on the verge of lifting as gusts battered their home. Such experiences highlight not only the danger to structures but also the potential impact on plumbing during extended water outages.
Following the storm, around 3,000 homes in Cornwall remained without water for several days. Fallen trees damaged major water mains near Helston and Wendron, and power outages at pumping stations further disrupted supply. To support residents, South West Water and local authorities set up bottled water stations at the Old Flambards in Helston, the Folly Field Car Park in Marazion, and Mullion School, ensuring access to clean water while mains were repaired.
So what does a storm like Goretti mean for your home’s plumbing, and how can you protect your system from the effects of extreme weather?
How Severe Weather Can Affect Plumbing
Contamination via Backflow
When water pressure drops or is completely lost, the normal flow in your pipes can reverse. This “backflow” may draw contaminated water from the ground or other non-potable sources into your home’s plumbing, potentially affecting drinking water safety.
Well Pump Damage
Homes with private wells rely on electricity to maintain water pressure. A power outage can cause well pumps to run dry, overheat, or sustain damage to the motor and electrical components, such as burned-out motor windings.
Air Locks and Trapped Air
Once water service is restored, air can become trapped in the pipes, causing sputtering taps, inconsistent flow, or even pressure surges that may stress your plumbing.
External Pipe and Roof Vulnerability
Trees falling on homes, debris in gutters, and damaged roofs can lead to leaks, blocked drains, and other plumbing complications. Gutters and downspouts are often overlooked but play a crucial role in directing water safely away from your property.
Steps to Protect Your Plumbing
While nobody wants to experience another storm on the scale of Goretti, there are practical steps homeowners can take to reduce the risk of plumbing damage:
-
- Turn off the main water valve if you expect to be without water for an extended period. This helps prevent issues when pressure returns.
-
- Switch off your water heater or turn off the circuit breaker if electricity or water is unavailable. This prevents the tank from burning out.
-
- Run taps for a few minutes once water pressure is restored to clear out trapped air or debris.
-
- Maintain gutters and drains early in the season. Remove twigs, leaves, and dirt, check for secure attachments, tighten loose gutters, and replace any that are rusty or damaged. Proper drainage reduces the risk of blockages and prevents excess water from pooling around your home.
Professional Plumbing Inspection
