Harmer Floor & Shower Drainage - Design Considerations The appropriate selection of a suitable Harmer Floor or Shower gully can be determined by a number of factors as outlined below. Building Regulations and Standards Harmer Floor and Shower gullies have been developed in accordance with current Building Regulations and British Standards to ensure that the gully is fit for purpose in its desired application. BS EN 1253 gives guidance on the appropriate general design, flow performance and load testing. Load Rating It is essential that the Harmer Floor or Shower gully can withstand the expected load. In accordance with BS EN 1253, load classifications are based on the following: Application BS EN 1433 BS EN 1253 (Drainage Channels) (Gullies for Buidings) BS EN 124 Flow Rate (Manhole & Gully Tops) A15 The flow rate is the maximum drainage capacity of the Floor gully, which is stated in litres per second (l/s). The flow rates are typically influence by a number of gully components which include grating type and size, waste basket, trap configuration*, sump depth and outlet spigot size. Expected flow rates can be determined by contacting the manufacturer of the appropriate discharging equipment. This can include shower heads, industrial kitchen equipment such as tilting kettles and other means of water discharge. K3 — L15 B125 M125 C250 — D400 — E600 — Flooring and Floor Construction There are a variety of floor finishes available, such as ceramic tile, sheet such as Vinyl, resin and cementitious floor. These will influence the type of grating or cover to be specified. Harmer Floor and Shower Gullies are available with a variety of tops and gratings for all different floor finishes. The floor construction, including depth of the structural slab and available floor build-up will influence the gully selection. Gullies are available with DPM clamping rings, extension pieces for deep floor construction and adjustable bezels for varying floor heights. Pipework The type, size and position of the waste pipework is all required to correctly select the correct Harmer Floor or Shower gully. Harmer gullies are suitable to connect to all pipework which include direct socketed pipe or connection via a coupling. Appearance The Harmer Floor and Shower Gully ranges are available with a wide range of gratings to suit a variety of applications. Stainless Steel or Nickel Bronze finish gratings can be considered for applications where a high aesthetic appeal is required. Cast Iron gratings are available where a low aesthetic appeal is required, such as in plant rooms or unfinished floor areas. Accessories The Harmer Floor and Shower Gully ranges are available with a large number of accessories to accommodate specific drainage requirements such as side inlets, large filtration of silt and backflow prevention. Custom made product are available for non-standard applications. Material and Finishes The correct material selection of the Harmer Floor and Shower Gully is an important consideration to ensure that the selected Gully is suitable in terms of corrosion resistance, hygienic design, strength, durability and appearance. *The flow rates shown in this brochure are based on maximum capacity of the grating. 12 www.harmerdrainage.co.uk
