Our 68mm downpipe is available in 3 different lengths in most colours, these are 2.5m, 4m and 5.5m. Circular downpipe is usually used in conjunction with half round, deepflow and ogee gutter systems but it can also be connected to square gutters using the RDS2 adaptor.
The pipe has an outside diameter of 68mm.
Rainwater pipes are always a pushfit joint - never use silicone or solvent weld on these systems as there might be a requirement to take them apart for cleaning or unblocking at some point in the future.
Floplast Rainwater systems carry a 10 Year Guarantee.
Installation
1. Using a plumb line, mark a vertical line on the wall from the running outlet to the drain.
2. Place an offset bend onto the base of the running outlet. Place a second offset bend on a length of downpipe and measure the section length required to join the two offset bends, cut a suitable length of downpipe – the “swan neck”.
3. Hold a downpipe clip centrally over the plumb line and mark the fixing holes on the wall with a pencil. Repeat down the wall, spacing pipe clips no more than 1.8m apart.
4. Drill the fixing holes.
5. Working from the top downwards, install the downpipe. If additional lengths of downpipe are required, join using a socket and pipe clip.
6. Leave a 10mm gap between the end of the pipe and the bottom of the pipe socket to allow for expansion. Fix a pipe clip over the joint.
7. Use wall plugs suitable for the substrate and when fitting pipe clip screws to ensure that the application is secure. Fix pipe/socket clips with 2 x 32mm x 6.5mm round head stainless steel screws.
8. Where required, fit a shoe at the bottom of the downpipe so that it directs water into the drain, if required. Fix the joint with a pipe clip.
