A: This depends on the number of outlets connected and their flowrates. In most cases 500 – 600mm from the bottom of the gutter to the underside of the siphonic header pipe is sufficient. If only one outlet is connected per downpipe, the shallowest connection is 150mm from gutter to the underside of the pipe. If your requirements are outside these measurements please contact our office for information.
