How do I re-route a condensate pipe to reduce the external run?

It is possible to terminate a condensate pipe into a rain water down pipe that terminates into the foul waste system. As with all externally-run condensate pipes, it is recommended to keep the external run to minimum and the pipe diameter to 32mm when exiting the property.

An air break must be installed between the appliance condensate outlet and the drainpipe connection. This needs to be external to the property to avoid flooding should the downpipe become blocked. Failure to include an external air break may result in severe damage to the appliance and may invalidate the warranty.
