Flowmate is designed to fit all residential gutter systems across Australia and New Zealand.
It suits both round (90mm and 100mm) and rectangular (100mm × 75mm and 100mm × 50mm) downpipes, and will fit the standard square and half-round style gutters typically found on most homes.
Each unit is 60mm tall, so you’ll need at least 65mm of clearance between the roofline and downpipe for ease of installation.
One per downpipe.
One downpipe left unprotected can overflow and trigger water damage, mould, and costly repairs — often not covered by insurance.
A simple DIY install.
Attach the base plate to the dropper, insert into your downpipe, and push down until the dropper locks into position — the ridges grip the inside of the pipe for a secure, lasting hold.
No tradie required.
Every alternative — gutter guards, hedgehogs, balloon plugs — has a fatal flaw. Flowmate doesn't.

THE HIDDEN COST
When a downpipe blocks, water backs up and forces its way into your walls, roof cavity, and foundations. The structural damage can run into thousands — and most insurers class it as a preventable maintenance issue, which means they won't pay.
Full Home Protection with Flowmate costs less than a single emergency plumber callout.

Most gutter accessories sit on top of your gutters and do nothing to protect the downpipe — the one point where blockages cause the most damage.
Flowmate works differently.
It installs directly into the downpipe, filtering debris while keeping water flowing freely at all times. No mesh to rust, no guards to collapse, no hidden buildup.
Flowmate is engineered to fit the most common Australian and New Zealand downpipe sizes — 90mm round, 100mm round, 100mm×50mm rectangular, 100mm×75mm rectangular, quad gutters, and half-round gutters.

Flowmate prevents debris from blocking your downpipes, keeps water flowing freely year-round, and protects your home from the water damage that blocked downpipes cause.
It requires no professional installation, no ongoing maintenance, and is backed by a 3-year warranty. It's the most cost-effective downpipe protection available for Australian and New Zealand homes.
One Flowmate per downpipe — no exceptions. A single unprotected downpipe is all it takes for water to back up and cause damage.

No. Flowmate is a simple DIY install. Attach the base plate to the dropper, insert it into your downpipe, and push down until the dropper's ridges grip the inside of the pipe and lock into position. No tradie, no professional required.
Gutter guards are designed to keep debris out of your gutters — but they sit directly over your downpipes, which means debris accumulates at the most critical point. Over time this causes overflow, hidden water damage, and costly repairs.
Flowmate protects the downpipe directly, costs a fraction of the price, and requires no professional installation.
Flowmate is compatible with the most common gutter profiles used across Australia and New Zealand, including quad, half-round, and fascia gutters.
It works with both tiled and metal roofing systems. If you have an unusual setup, contact our team and we'll advise before you purchase.
When a downpipe blocks, water has nowhere to go. It backs up into the gutter, overflows, and forces its way into your fascia, walls, roof cavity, and foundations.
Flowmate keeps the downpipe clear at all times, so water drains freely regardless of how much debris is in the gutter — eliminating the root cause of most preventable water damage in Australian homes.
