We also stock deepflow in cast iron effect for a more traditional look that still maintains all the benefits of plastic deep guttering in high capacity deepflow.
Please take a look at this short video which highlights the differences between deepflow and standard half round gutters.
The carrying capacity of any gutter system is determined not only by its size but also by the position of the rainwater downpipes in relation to the gutter and the fall to which it is laid. All gutter systems can actually be fixed level, although we would recommend that a fall of 1:600 is incorporated (this equates to approximately 1 inch in 50 feet or 2.5cm in 15 metres in metric terms).
Floplast deep flow guttering's capacity varies between 2.05 litres per second (fixed level with the outlet at one end) and 5 litres per second (fixed at 1:350 with a central outlet). This is approximately twice the capacity of our half round guttering system and as such it can cope with the flow from large or particularly steep pitched domestic roofs. If required, the capacity of this system can be increased even further by the use of 80mm downpipes instead of 68mm – however the 68mm Downpipe is perfectly adequate to be used with deepflow guttering - please contact us if you require further details.
With this system we recommend that fascia brackets are installed at maximum 1.0m intervals when using standard 68mm downpipes.
