Frequently Asked Questions

What makes Flowmate different from other gutter solutions?

Flowmate isn’t a gutter guard — it’s downpipe protection.

It’s designed to keep water flowing by stopping blockages where they actually matter — at the outlet. No screws, no overengineering, and no need to remove anything during cleans.

It’s a simple, smart insert that protects your home from overflow and water damage without getting in the way.

What size downpipe will Flowmate fit into?

Flowmate’s dropper (70mm x 35mm) is designed to fit most standard residential downpipes in Australia and New Zealand — including 100x75mm square and 90mm round.

It usually slides in with no modifications, but we can tweak it to suit tricky setups. Not sure? Get in touch before you buy.

What are the benefits of using Flowmate?

Flowmate is a smart downpipe insert that keeps water flowing and stops blockages where they start — at the outlet.

✅ Cost-effective
✅ Easy DIY install
✅ No screws, no tools
✅ Works even when gutters are full
✅ Adapts to most gutter and downpipe types
✅ Makes yearly cleaning faster and safer

It’s a simple way to protect your home from overflow and water damage — without the hassle of traditional systems.

How many Flowmate units do I need for my home's gutters?

Simply count your gutter's downpipes and buy a Flowmate for each one.

How does Flowmate prevent gutter clogs and water overflow?

Flowmate prevents gutter clogs and water overflow by allowing rainwater to flow smoothly while blocking larger debris like leaves and twigs. Its innovative design ensures that water continues to drain efficiently, reducing the risk of blockages and stagnant water, ultimately protecting your home from potential water damage.

Can I install Flowmate myself, or do I need professional installation?

You can easily install Flowmate yourself! It is designed for simple DIY installation, allowing homeowners to set it up without the need for professional help. Learn more here.

What maintenance is required for Flowmate?

Flowmate requires minimal maintenance. It’s recommended to periodically check for any debris accumulation on the surface and gently clean it with a broom or hose as needed. An annual flush of the gutters is also advisable to remove any fine particles, ensuring optimal performance throughout the year.

How does Flowmate help prevent leaf and debris buildup?

Flowmate sits directly over the downpipe, stopping leaves and debris from entering the outlet while letting water flow freely — even when gutters are full.

Unlike systems that try to block debris at the top, Flowmate works with your yearly clean, not against it. No clog-prone mesh, no removals — just clear downpipes and hassle-free maintenance.

Is Flowmate compatible with all types of gutters and roofing systems?

Yes, Flowmate is designed to be compatible with various types of gutters and roofing systems, making it a versatile solution for homeowners. Whether you have metal, tile, or other roofing materials, Flowmate can effectively integrate into your existing gutter setup.
