Ensure that fascias are straight and true and in good condition. Swish recommends that

timber roofline components are replaced with Swish cellular PVC fascias, soffits and bargeboards for longevity, lower lifetime costs and a reduced carbon footprint over the service life of the building.

 

The gutter should be fitted as high as possible up to the edge of the roof and fixed at a fall of

between 1mm/m and 3mm/m. In areas where snow is likely to accumulate on the roof, ensure

that the outer edge of the gutter does not project above the line of the roof. Neither should the roof covering project far over the inner edge of the gutter. Down pipes should be located directly above the drain opening.

 

Fix the end fascia bracket to the fascia board within 75mm of where the stopend or corner will be located. The gutter can finish flush with the end tile or extend beyond it by no more than half the depth of the gutter.

Tie a plumb line to the end bracket and feed it through the outlet. This allows the installer to

position the outlet accurately above the drain point and ensure the correct fall from the end

fascia bracket before securing the outlet. Fit the intermediate fascia brackets and gutter joints in place using the plumb line as a guide. Feed the back edge of the gutter fully under the back clips of all the fascia brackets, unions, corners etc. Ensure that the gutter ends line up with the markings on the inside of each union or outlet unit (to allow for thermal movement) and push all front clips firmly and fully over the front edge of the gutter. Swish gutter seals are pre-treated with silicone but installers are advised to apply a spray of silicone prior to assembly.

 

The offset in the pipe is formed by using two 112degree  bends to return the pipe to the wall. If

the soffit is small and the two offset units need to be close to one another they will still require

a small section of pipe between them to make the joint fit properly. It is important to allow for expansion of the main pipe. This is best concealed in the offset or a pipe socket. Allow 10mm expansion gapper 5m of pipe.

 

Swish Rainwater Systems are compatible with some elements of other guttering systems.

Designers and installers should consult SwishTechnical Services for guidance.

Swish gutters and pipes are supplied in polyethylene sleeve wrapping. They will withstand general site handling, however, the following guidelines should be observed:

Loading and unloading should be carried out by hand.

 It is advised that products are stacked on a flat, firm base, to no more than 1m high and

protected from the elements. Wherever possible a dedicated racking system is strongly

recommended with side supports at intervals not exceeding 1m.

 Set aside off cuts and store carefully for re-use.

 Contact with solvents and organic based compounds such as bitumen products, paint or

creosote should be avoided.

 Boxed fittings should be stored under cover away from damp surfaces to retain the integrity

of the box.

 Please recycle packaging where possible.
