TESTING

Whilst it would be preferable to water test the rainwater system, under most site conditions this is not practical. If testing is required it should be done when the system is complete.

The outlets should be blocked and the gutters filled two thirds of capacity. After 5 minutes the joints should be checked, unblocking the outlets and discharging the water will test the pipes.

Any remedial works should be undertaken, retest until satisfactory.
