Drainage Channels with Side Siphon

Drainage Channels with Side Siphon — the side siphon solution is more compact and simpler than the central model; water flows in one direction lengthwise along the channel; suitable for channels of various lengths, but performs best in shorter sections or when the sewer connection is located at the edge of the building or along a wall.

Side siphon design and water flow direction

Drainage Channels with Side Siphon — in a side siphon, the siphon is located at one end of the channel; water flows along the channel in one direction and reaches the siphon at the end. Floor slope — for water to flow effectively towards the siphon, the floor must have a 1–2% slope in the direction of the channel; with the correct slope, water does not pool on the floor. Siphon position and sewer connection — the sewer pipe is connected to the siphon at the end of the channel; this solution is more convenient if the sewer connection is located near a wall or at the edge of the building. Asymmetric installation position — the channel can be installed with the siphon on the left or right, depending on the position of the sewer connection; see Drainage Channels. Cleaning access — the siphon in the end position is easier to access for cleaning; it can be reached from the end of the channel without dismantling the entire channel structure.

Side siphon channel vs central siphon channel

Drainage Channels with Side Siphon — the choice between a side and central siphon depends on several factors. Channel length — the side siphon model is optimal for channels up to 800–1000 mm; for longer channels over 1000 mm, water flow from the far end may become inefficient, and a central siphon is a better choice. Sewer connection location — if the sewer is accessible on the wall side or at the end of the channel, a side siphon is a more natural solution without additional steps. Installation simplicity — the side siphon model is structurally simpler; fewer connections, fewer potential leak points; see Drainage Channels with Central Siphon. Maintenance convenience — cleaning a side siphon is often easier, as access from the end of the channel is straightforward.

HACCP and hygiene requirements for side siphon channel maintenance

Drainage Channels with Side Siphon — within HACCP, the floor drainage system is a critical control point in any food processing or preparation area. Daily cleaning — at the end of each shift, the channel surface (grating) must be removed and cleaned; food residues, greasy deposits and other dirt accumulate in the channel and create a risk of bacterial growth. Deep siphon cleaning — once a week, the siphon should be cleaned with a liquid degreaser; water alone is not enough for the greasy film that builds up inside the siphon. Blocking sewer odours — if the siphon has dried out (for example, after a long period of disuse), it must be refilled with water to restore the odour trap; see Two-Part Floor Drains. Separate channel flows — drainage channels in food preparation zones must not intersect with drains from toilet or waste areas.

Usage scenarios for drainage channels with side siphon in HoReCa

Drainage Channels with Side Siphon — side siphon channels are a convenient solution for various HoReCa spaces where the sewer connection is located along a wall. Café dishwashing corner — in a compact café dishwashing zone, the channel with side siphon is positioned along the back wall; the sewer runs along the wall to the basement. Hotel room cleaning zone with floor washing — in a floor washing area, the side siphon channel is installed near the room entrance wall. Restaurant kitchen antechamber — changing room or goods receiving area with floor drainage; the side siphon is connected to the sewer network located at the edge of the room.

Frequently asked questions

Can a side siphon channel be installed with the siphon on the right or left? Drainage Channels with Side Siphon — most BHS side siphon channel models are available with the siphon on the left or right side or as universal models where the siphon can be repositioned; contact BHS for precise model selection based on the sewer connection position; see Drainage Channels.

What pipe diameter connection is required for a drainage channel? Drainage Channels with Side Siphon — standard drainage channels connect to the sewer with a DN50 (50 mm) or DN70 (70 mm) pipe; for higher water flow (e.g., a dishwashing machine), a DN70 pipe is recommended; contact BHS for precise specifications; see Drainage Channels with Central Siphon.
