A floor drain is a small line on a drawing, but it carries three decisions that are awkward to change once floors are poured: the right type for the location, the right model variant for the pipework below it, and the right grate and trap arrangement for the space. This guide walks through those decisions using the Fanoos \u0645\u0635\u0627\u0631\u0641 \u0627\u0644\u0623\u0633\u0637\u062d \u0648\u0627\u0644\u0623\u0631\u0636\u064a\u0627\u062a \u0648\u0627\u0644\u0645\u0646\u0627\u0637\u0642<\/a> range, which covers finished floors, external areas, showers and planted areas, plus the cleanouts and receptors that complete a drainage layout.<\/p>\n

Types by location<\/h2>\n

The most reliable way to select a drain is to start from where the water is: inside a finished room, in an external or below-grade area, in a shower, or in a landscaped zone. Each location makes different demands on the drain body, the grate and the connection below.<\/p>\n

Finished floor drains<\/h3>\n

Finished floor drains sit flush with tiled or screeded floors in bathrooms, kitchens, washrooms, plant rooms and service areas, where the grate has to sit level with the finished surface. The core of the Fanoos range is the 5010S \u0645\u0635\u0627\u0631\u0641 \u0623\u0631\u0636\u064a\u0629 \u0644\u0644\u0645\u0646\u0627\u0637\u0642 \u0627\u0644\u0645\u0634\u0637\u0628\u0629<\/a>, offered in several model variants (5010S, 200D4MD, 5010SB and 5010RB) so the body can be matched to the outlet arrangement shown on the drawings. Alongside it sit the Finished Floor Drains with Trap 5040S, where the trap is integral to the drain, and the Multi Inlet Floor Drains 5030S for positions where more than one waste line discharges at the same point. Where a waste line must discharge indirectly \u2014 for example from equipment \u2014 the Finished Indirect Waste Drain 5010F covers that arrangement.<\/p>\n

Finished floors also need access points. The range includes Finished Floor Cleanouts in the 6010R, 6010S and 6020S models, and the FD 6010RC Cast Iron Cleanout, which give rodding and maintenance access at floor level without breaking into the slab later.<\/p>\n

Area drains<\/h3>\n

Area drains serve external and below-grade locations \u2014 yards, ramps, basements, loading areas and podium levels \u2014 where the drain is typically set in a sump and has to collect surface water over a wider area. The Fanoos range is built around sump bodies: the Deep Sump Area Drain 5060D (with the 5060DH variant), the Large Sump Area Drains 5080SB and 5080RB, and the Small Sump Area Drains 5070WS, 5070RB and 5070SB. Where drainage has to be received from a pipe or channel discharging above the drain rather than connected directly, the Deep Sump Area Drain Receptor 5090G provides the receiving body. Choosing between the deep, large and small sump models is a matter of matching the body to the build-up depth and pipework shown on the project drawings \u2014 which is why this check belongs at specification stage, not at installation.<\/p>\n

Shower drains<\/h3>\n

Shower drainage is a finished-floor application with its own grate requirements, and the relevant models sit in the \u0645\u0635\u0627\u0631\u0641 \u0627\u0644\u0641\u0648\u0644\u0627\u0630 \u0627\u0644\u0645\u0642\u0627\u0648\u0645 \u0644\u0644\u0635\u062f\u0623<\/a> range: the Floor & Shower Drains with Drop-In Grate 7160 are the point-drain option in this family, and the same range carries linear and wall-type formats for shower layouts that drain along a line rather than to a single point. When a shower area appears on the schedule, confirm whether the design shows a point drain or a linear channel before selecting the model, because the slab build-up and waterproofing detail differ between the two.<\/p>\n

Planting drains<\/h3>\n

Landscaped and planted areas need drainage that works through soil and planting build-ups rather than a hard finish. The range covers this with the Planting Drain 5210 and the Planting Drain 5220, the latter offered in 5220 and 5220GX variants. These positions are easy to miss on a drainage schedule because they sit in the landscape package rather than the architectural finishes, so they are worth checking explicitly when the BOQ is assembled.<\/p>\n

Sizes and outlets<\/h2>\n

Drain “sizes” in a catalogue like this one are expressed as model families and variants rather than as a single dimension table, because the same drainage point can need different bodies and outlet arrangements depending on the pipework below it. In practice, selecting the size means selecting the correct variant within the family that fits the position. The main families in the range are:<\/p>\n\n\n\n\n\n\n\n\n\n\n

Three checks settle the outlet question for each position. First, the outlet size: the connecting pipework on the drainage drawings fixes what the drain body must suit, so read it from the drawings rather than assuming a default. Second, the outlet direction: whether the discharge leaves the body vertically or horizontally determines which variant works within the slab or ceiling void available. Third, the build-up: the depth between the finished surface and the outlet connection decides whether a standard body, a sump body or a receptor arrangement is the workable option. If any of the three is unresolved when the quotation is requested, flag it in the enquiry \u2014 it is far cheaper to resolve on paper than on site.<\/p>\n

Traps and odour control<\/h2>\n

A trap holds a plug of water in the drainage line that blocks sewer gases from travelling back into the occupied space. Where a floor drain connects to a line without a trap elsewhere in the run, the drain itself needs to provide that seal. The Finished Floor Drains with Trap 5040S cover positions where the trap is built into the drain, and in the stainless range the Floor Drains with Odour Trap 7260<\/a> address the same requirement for shower and wet-area positions. Two practical points are worth building into the specification: drains in rarely used areas \u2014 plant rooms, stores, parking levels \u2014 can lose their trap seal through evaporation, so the maintenance regime should include periodic flushing of little-used drains; and a position that shows a trap on the drawings should not be value-engineered into an untrapped drain at procurement stage, because the odour problem only appears after occupation, when it is expensive to trace.<\/p>\n

Materials in this range<\/h2>\n

Material is a selection point on every drain position, and it has to be confirmed per position from the project specification rather than assumed from the model name. One product in the range states its material in its name: the FD 6010RC Cast Iron Cleanout, specified where a heavy-duty cleanout body is required. Beyond that, the catalogue’s products carry material and finish designations chosen against the schedule \u2014 the grate finish for a tiled bathroom is a different decision from the body for a plant room or an external area. When you send a drainage schedule for quotation, include the material and finish specified for each position; where the specification is silent, say so, and the selection can be worked through before the quotation is issued.<\/p>\n
