01 Quick Answer
Looking after your drainage system helps prevent future problems, protects your investment and keeps your drainage operating efficiently.
Following our aftercare recommendations also helps ensure your guarantee remains valid where applicable.
02 Why Aftercare Matters
Regular maintenance plays an important role in protecting your drainage system.
Good aftercare can help:
-
Reduce the risk of unexpected blockages
-
Extend the lifespan of your drainage system
-
Protect your property from leaks and flooding
-
Identify developing problems before they become major repairs
-
Keep your drainage system performing as intended
Preventative maintenance is almost always more cost-effective than emergency repairs.
03 Our Aftercare Recommendations
We recommend a few simple steps to keep your drainage system in good condition.
Arrange Periodic Inspections
Depending on the age and usage of your drainage system, occasional CCTV inspections can identify developing defects before they become expensive repairs.
Keep Drains Clear
Regularly remove leaves, silt and debris from gullies, channels and drain covers.
Dispose of Waste Correctly
Avoid flushing wipes, sanitary products, fats, oils, grease and other unsuitable materials into the drainage system.
Act Early
Slow drainage, bad smells or unusual noises are often early warning signs that should be investigated before they worsen.
Keep Your Documentation
Retain your reports, drawings and guarantee information for future reference and when selling your property.
04 Maintenance Checklist
Simple routine maintenance includes:
-
Check drain covers remain secure.
-
Keep gullies free from leaves and debris.
-
Dispose of waste responsibly.
-
Watch for slow drainage or unpleasant odours.
-
Arrange CCTV inspections when recommended.
-
Address minor issues promptly.
A little maintenance can significantly reduce the likelihood of future drainage problems.
05 What To Avoid
Certain actions can damage your drainage system or increase the likelihood of blockages.
Avoid:
Pouring fats, oils or grease down sinks
Flushing wipes, sanitary products or cotton buds
Disposing of paint, chemicals or solvents into drains
Driving or parking over drainage systems unless designed to carry vehicle loads
Ignoring warning signs such as slow drainage or repeated blockages
Good drainage habits help protect both your property and the environment.
06 Addressing Issues Early
Small problems rarely improve on their own.
If you notice:
-
Slow-draining fixtures
-
Bad smells
-
Gurgling sounds
-
Repeated blockages
-
Localised flooding
It's always best to seek advice early. Prompt investigation can often prevent more extensive repairs.
Our team is always happy to provide guidance if you're unsure.
