                                            Handling and storage of materials

                                            Care should be taken when handling PVCu gutter and rainwater pipes. Excessive
                                            scratching can ruin the aesthetic appearance of the gutter and affect joint
                                            sealing. Cold weather reduces the impact strength of PVCu and extra care is
                                            needed in wintery conditions.

                                            When pipe is delivered to site, it is recommended that loading and unloading
                                            of pipe and gutter lengths is performed by hand without the use of mechanical
                                            lifting aids.

                                            Always store pipes and gutters on flat surfaces, ensuring that the surface is free
                                            from sharp protrusions. Bundles of pipes and gutters can be stored up to 3 m
                                            high without support. Loose gutter and pipe requires supports every 2 m. Fittings
                                            should remain in their packaging until needed to reduce damage by scratching.

                                            Testing completed rainwater systems

                                            Once the system installation is complete, testing can be carried out by
                                            discharging water, from a hosepipe, at all high points in the system and checking
                                            to make sure that the water discharges down the outlets and through the
                                            rainwater pipes without leakage or pooling of water in the gutter.

                                            3 THE MAINTENANCE AND

                                            SERVICE REQUIREMENTS OF

                                            GRAVITY RAINWATER SYSTEMS


                                            Maintenance of guttering systems is an essential activity to keep systems
                                            working correctly. In this next section of the chapter, we will look at those
                                            essential items of maintenance that are carried out during planned preventative
                                            maintenance or fault rectification.
                                            These include:

                                            l  visual inspections and fault finding
                                            l  leakage repairs
                                            l  replacement of defective gutters and fittings
                                            l  cleaning and clearing blockages.
                                            Different gutter materials require different methods of working and repair, and
                                            it is important that we have knowledge of the basic repair techniques required.

                                            Visual inspections and fault finding

                                            Visual inspections are the first part of the maintenance and repairing activity.
                                            Visual inspections help in establishing the overall condition of the gutter
                                            and rainwater pipe installation, joints and fittings, and in pinpointing specific
                                            problems, such as those listed in Table 8.10.
