Warranty and Maintenance

Warranty for exterior membrane drainage outlets: 

Free from defects of material and workmanship for 15 years. Tea staining may occur over time. This is not considered a material defect and is not covered under warranty terms.

Maintenance for exterior membrane drainage outlets: 

Regular inspections (at least monthly, and after every significant storm) should be conducted to remove any accumulation of debris from box-gutters, sumps and around the drain areas. Accumulation of such material can lead to blocked drains and overflow events. The overflow outlet discharge pipes should be monitored during rain events. Any water discharge is an early warning that may indicate a partially blocked drain.
