What is Smartflo gutter?
Smartflo is a revolutionary, fully integrated gutter and leafguard system. It is specifically designed to reduce gutter maintenance, prevent gutters from becoming clogged with leaves avoid damage due to blocked gutters causing back-flow into the building and reduce bush fire risk. The attractive smooth lines enhance any architectural design. For those who collect tank water, Smartflo maximises catchment and reduces contaminants. Smartflo is manufactured using BlueScope Colorbond steel for strength, durability and reliability in a broad range of traditional and modern colours.

How does Smartflo work?
Smartflo has an integrated pre-gutter above the main gutter, which catches and separates leaves and debris from the water, allowing only the water to enter the main gutter. Water flows into the main gutter through a series of raised filters positioned along the pre-gutter. Leaves and debrisare left behind to dry out and blow away. Once inside the main gutter, the water flows unobstructed to the downpipes or tanks.

What are the filter spacings?
Standard filter spacing is 500mm which is ample for all but the heaviest tropical storms. Where valleys concentrate the flow, additional filters can be inserted if required.

top

What happens if a filter blocks?
Five filters have the same capacity as one standard 90mm round downpipe. As downpipes are fitted every 8 to 12 metres normally, and are thus fed by 16 to 24 filters, partial blockages have very little impact on the system efficiency.

What is the capacity of Smartflo?
Smartflo has been independently tested by the University of Newcastle and found to cope with 190mm of rain per hour. The cross-sectional area exceeds that of conventional quad gutters by 20-50%.

top

Won't water deflect off the pre-gutter and over the front?
During rain, there is a pool of water built up in the pre-gutter before the filters start to run. This "braking" pool absorbs the energy from the flow out of the roof corrugates and dampens the run off speed.] Some overflow can be experienced on low pitched rooves (under 6?) and in exceptionally heavy storms (over 100mm per hour).

top

What happens if Smartflo overflows?
A key design element of Smartflo is that the front of the gutter is lower than the rear, so that in the event of overflow, the water will always flow off the front of the gutter, and consequently, away from the building.

top

Can frogs, snakes or birds get into Smartflo?
The Smartflo system is an enclosed gutter system. Provided the outlet ends of downpipes are fited with vector screens, vermin are excluded from entering the system. The shallow pre gutter also makes for easier ball retrieval.

top

Does Smartflo require special downpipes?
No. Smartflo can connect to any existing or standard downpipe. We recommend that you install sufficient downpipes to cope with a one in twenty year storm in your area, as this is usually the limiting factor in heavy downpours.

top

What about leaves from different sorts of trees?
Smartflo is very effective on leaves from eucalypts and broad leaf deciduous trees. Pine needles, gum nuts, sticks and the flowers from some ornamental trees do not blow out and may need to be manually cleared from time to time. Because the pre-gutter is shallow, manual clearing by brushing, blowing or hosing, is much simpler with Smartflo than with conventional quad gutter. Smartflo can supply a brush which clips to the end of an extendible pool pole to allow cleaning from the ground.

top

Will Smartflo cope with steep or low-pitched rooves?
Low-pitched rooves (under 6?) can experience some overflow in heavy rain. The longer the distance from the ridge to the edge, the greater the risk of overflow. Notching the corrugates reduces the propensity for overflow. The upper limit for Smartflo is 65?. There are very vfew rooves built at this pitch or higher.

top

Will Smartflo fit all types of fascias?
Smartflo can be fitted onto timber or steel fascia, or directly onto exposed rafters. Fascia/rafters should be in good condition and straight. If a string line shows that rafter ends or fascias are not straight it may be necessary to pack brackets, as Smartflo does not flex readily. Packing strips are available as an accessory in 1mm., 3mm, or 5mm thicknesses.

top

Can I install Smartflo myself?
Yes. The average home handyman can install Smartflo. An installation guide is included with every order shipped. It is recommended you check statutory requirements for your region before commencing installation.

top

Why is Smartflo value for money?
Smartflo is a cost effective solution for those replacing existing gutters, those who seek to reduce bush fire risk or back-flow into eaves. Conventional gutter and leafguard combinations vary considerably in cost and performance, and usually incur two installation costs. Installation of Smartflo is a single operation, providing a cost advantage
