Product information
Prevent blocked downpipes and protect your home from water damage — fast.
Flowmate is a low-maintenance, tool-free insert that drops directly into your gutter outlet, stopping leaves and debris from blocking your downpipes. Designed to suit common gutter systems in New Zealand — including Marley 90mm round and 100x75mm rectangular downpipes — Flowmate is an easy, effective way to keep water flowing and reduce the risk of overflow and damage.
Blocked downpipes are a leading cause of water damage in Kiwi homes. While traditional gutter guards often clog up or require ongoing maintenance, Flowmate solves the problem right where it starts — at the downpipe outlet.
