Maintenance
Siphonic pipework itself is maintenance free, due to the self-cleansing properties of Siphonic Drainage Systems.
However, in order to ensure the correct operation of Siphonic Drainage Systems Gutters and Outlets need to be inspected and cleaned on a regular basis to ensure that any debris buildup around the Siphonic Rainwater Outlets is cleared to ensure the systems are draining effectively.
What's recommended in terms of frequency?
The British Standard for Siphonic Drainage Systems (BS8490:2025) recommends that this maintenance is undertaken a minimum of 4 times per year.
In addition to this it is also recommended that an annual visual inspection of the system and bracketry is also undertaken.
