Factory Supply Attachable Bidet for Toilet

This bidet module is engineered to retrofit onto standard vitreous china toilets without altering the fixture’s structural integrity. It connects to the existing water supply via a 1/2‑inch NPT inlet and provides a controlled spray pattern for posterior cleansing. The unit is intended for environments where hygiene upgrades are required while maintaining the original toilet’s load‑bearing capacity and flush performance.

Design and Construction

The housing is fabricated from acetal copolymer (POM) with a tensile strength of approximately 70 MPa and a low moisture absorption rate (<0.2 %). Internal flow channels are molded with a smooth finish to minimize turbulence and prevent sediment buildup. A stainless‑steel (AISI 304) nozzle tip, 2.5 mm orifice diameter, delivers a laminar jet at pressures between 150 kPa and 300 kPa, adjustable via a brass‑bodied flow regulator.

Mounting hardware includes a zinc‑plated steel bracket with a 3‑mm thick steel strap that clamps to the toilet bowl’s rim using two M6 set screws. The bracket distributes load over a 45 mm contact area, ensuring stress remains below the porcelain’s flexural strength of ~55 MPa.

Technical Specifications

Materials

• Acetal copolymer (POM) – selected for chemical resistance to cleaning agents and low creep under constant load.
• Stainless steel nozzle – provides corrosion resistance in potable water and maintains orifice dimensions over >10⁵ cycles.
• Brass flow regulator – offers precise flow control with dezincification resistance.
• Zinc‑plated steel bracket – balances strength with corrosion protection for humid restroom environments.

Applications in Industrial Facilities

In manufacturing plants, warehouses, and food‑processing sites, restroom hygiene directly impacts worker compliance with sanitation protocols. Retrofitting existing toilets with an attachable bidet reduces reliance on disposable wipes, lowering solid waste generation and associated disposal costs. The modular design allows installation without downtime, as the unit attaches to the bowl’s rim and connects to the existing supply line via a quick‑connect fitting.

Facilities that require frequent wash‑downs benefit from the bidet’s self‑draining nozzle, which prevents water retention and minimizes bacterial growth. The pressure‑adjustable flow enables adaptation to varying water‑supply conditions common in older plant infrastructures.

Installation and Compatibility

The bracket slides onto the toilet bowl’s rim and is secured with two M6 set screws torqued to 4 Nm. No drilling or alteration of the vitreous china is required. Water connection uses a 1/2‑inch NPT to 3/8‑inch compression adapter (included) that mates to the standard shut‑off valve. The unit’s overall height adds approximately 45 mm to the fixture, compatible with most standard‑height toilets (400‑460 mm bowl rim height).

Before installation, verify that the supply line pressure does not exceed 400 kPa; if higher, install a pressure‑reducing valve upstream. The bidet’s internal check valve prevents backflow, meeting backflow prevention codes for potable water systems.

Quality Assurance

Each housing undergoes dimensional inspection using a coordinate measuring machine (CMM) with a tolerance of ±0.15 mm on critical mating surfaces. Flow‑rate testing is performed on a calibrated test rig at 200 kPa, verifying output within ±5 % of the target 0.8 L/min. Material certification includes batch‑specific POM melt flow index (MFI) reports and stainless‑steel alloy verification via optical emission spectrometry.

Finished units are subjected to a 100‑cycle pressure pulsation test (0 kPa → 300 kPa → 0 kPa) to validate seal integrity. Any unit exhibiting leakage >0.1 mL per cycle is rejected. Final visual inspection checks for surface defects, flash, and proper labeling of flow‑adjustment markings.

Customization Options

• Nozzle orifice diameters: 2.0 mm, 2.5 mm (standard), 3.0 mm – to tune spray intensity.
• Flow regulator preset ranges: 100‑200 kPa, 200‑300 kPa, or fully adjustable knob.
• Housing color options: natural POM (off‑white), black UV‑stabilized POM for high‑light areas.
• Alternative bracket materials: stainless steel (AISI 304) for corrosive environments.
• Private labeling: laser‑etched logo on housing top surface (maximum area 30 mm × 15 mm).

Frequently Asked Questions

Can the bidet be installed on elongated and round toilet bowls?

Yes. The bracket’s adjustable span accommodates bowl rim widths from 340 mm to 380 mm, covering both elongated (≈380 mm) and round (≈340 mm) designs.

What water supply specifications are required?

A potable cold‑water line with pressure between 150 kPa and 400 kPa is suitable. If pressure exceeds 400 kPa, an upstream pressure‑reducing valve must be installed.

Are replacement parts available?

Nozzle tips, flow regulators, and brackets are stocked as spare parts. Part numbers are provided in the product data sheet; lead time is typically 7‑10 business days for stock items.

Is the unit compatible with low‑flow toilets?

Yes. The bidet operates independently of the toilet’s flush volume; it only draws water from the supply line at the set pressure, so low‑flow fixtures (≤6 L per flush) do not affect performance.
