Blocked downpipes cause water damage. It's that simple. When leaves and debris build up at the outlet, water has nowhere to go, it backs up into the spouting, overflows, and gets into places it shouldn't.
Flowmate is a downpipe leaf guard that sits at the outlet between your spouting and downpipe. Leaves can't get through. Water can. It installs in seconds and works without maintenance.
Pricing
1 - 4 Pack = $55 per unit / 5 - 6 Pack = $49.5 per unit
7 -9 Pack = $46.75 per unit / 10 Pack = $44 per unit
How It Works
Place the plate over the outlet, drop Flowmate in, and snap it on. That's the full installation. No tools, no trades, no drilling. One Flowmate per downpipe.
When leaves land in your spouting, they sit around the Flowmate and dry out. Water passes through. When it's time to clean, the debris lifts straight off.
Will It Fit?
Flowmate fits the residential downpipe sizes used across New Zealand:
Round downpipes — 80mm and 100mm
Rectangular downpipes — 100mm × 75mm and 100mm × 50mm
Suits standard square and half-round gutters
The unit is 60mm tall. You'll need at least 65mm of clearance between the roof and the bottom of the gutter for installation.

How Many Do You Need?
One Flowmate per downpipe outlet. Count your downpipes — that's your number.
Most NZ homes need 5–7 units. Larger properties or homes with more complex rooflines may need more.
