3-way tap 25 cm 1 pc

3-way tap 25 cm, 1 pc: single-lever mixer with 25 cm high spout and integrated three-way function, designed to allow the separate supply of mixed mains water (hot/cold) and dedicated water (e.g. treated/filtered water) without the risk of interchange. Product designed for installation in domestic and professional water points where you want to maintain the possibility of a dedicated flow for drinking use, maintaining ergonomics, practicality of use and a compact size. Delivered in a single piece (1 pc) complete with the body column and the hydraulic passages necessary for connection to the three lines.

Functional design with a 25 cm high spout that facilitates filling containers and cleaning the tub; ergonomic lever for temperature and flow control, and separate control or independent channel for filtered water. Ideal for those who use domestic under-sink filtration systems and want a single unit that integrates both the mixing function and the line dedicated to treated water, reducing overall dimensions and simplifying assembly.

Therapeutic Indications

Indications for use: the 25 cm 3-way tap is suitable for use in water points where the simultaneous supply of mixed water (hot/cold) for general use and separate water for drinking or treated use is necessary. Typical applications include domestic kitchens, light professional kitchens, bars and offices, mobile housing units such as campers and boats (always check compatibility with the specific application system), and water points in non-chemical laboratories where a dedicated channel for drinking quality water is required. The product allows you to avoid manual switching between separate taps, offering an integrated solution that improves operational efficiency and reduces clutter on the worktop. It is particularly suitable for installations with under-sink water treatment systems — the third passage is designed to be connected to a separate circuit that feeds directly to the tap spout without mixing, preserving the characteristics of the filtered water. Furthermore, the 25 cm high spout facilitates daily operations such as filling pots and jugs and cleaning taller dishes, improving ergonomics compared to low spout taps. During use, it is important to respect the correct hydraulic connection procedures: the line dedicated to treated water must be connected exclusively to filtration devices or circuits designed for drinking water to avoid contamination and ensure that the channel remains separated from the main network in all operating conditions. The adoption of the 25 cm 3-way tap therefore allows for safer and more practical management of drinking water and general use, reducing the risk of involuntary mixing and simplifying daily cooking and serving operations.

Composition

The 25 cm 3-way tap consists of a solid body specially sized to integrate three distinct hydraulic passages: a channel for hot water, one for cold water and a third channel dedicated to treated or filtered water. Primary materials include solid brass for the body, chosen for its corrosion resistance and mechanical stability; external finishes available in chrome or brushed steel to increase durability and facilitate cleaning; internal watertight ceramic cartridge for mixing and flow control, designed to ensure long life and precise lever response. The gaskets are normally made of resistant elastomers (EPDM or silicone suitable for contact with drinking water) to prevent leaks and resist temperature variations; O-rings and washers are selected to minimize maintenance and delay the aging of moving parts. The third channel is separated internally with a dedicated duct which avoids cross-contamination between filtered water and mains water; this duct may have push-in fittings for direct connection to the under-sink filtration system or threaded connections for specific hoses, depending on the mounting configuration. The connection hoses included (if supplied) are made with an external anti-slip coating and internal piping certified for food use, while the stop valves and upstream fittings must be suitable for the pressure of the system. Smooth internal surfaces are provided to reduce the formation of encrustations and facilitate any washing operations; the exposed parts are treated to resist wear, light abrasions and household cleaning agents. The product is designed to be assembled with components that maximize its durability and allows the easy replacement of cartridges and seals without the need for invasive interventions on the main body, facilitating routine maintenance over time.

Contraindications

Do not use the 25 cm 3-way tap in systems that supply fluids other than drinking water or technical water compatible with metallic materials and rubber; use with corrosive liquids, solvents, oils or aggressive solutions can damage the seals, metal surfaces and internal mechanisms. It is not suitable for contact with very high temperature water coming from systems not intended for domestic use (for example steam or water at industrial pressures/temperatures) as the cartridges and seals could degrade rapidly. Avoid installation in systems where the water has chemical or microbiological characteristics that do not comply with human consumption without first adopting suitable treatments or checks: water with a high concentration of suspended solids, particular contaminants or non-drinking water can block the thinner ducts of the third passage and compromise their functionality. Do not install the tap without backflow protection devices and without stop valves where required by local regulations: the presence of a separate channel does not exclude the need for anti-return measures to prevent contamination of the network. Do not use the third channel as a line for saturated solutions of salts or for additives intended exclusively for specific systems (for example chemical treatment plants), nor subject the body of the tap to violent shocks or excessive twisting during installation. In the presence of particularly hard water or water with a high iron and manganese content, it is advisable to provide adequate preliminary treatment or frequent maintenance: the absence of these precautions can lead to deposits that reduce the flow rate and damage the sealing seats. Furthermore, avoid using the tap in installations where full compatibility with specific specific regulations is required without having verified that the installed model complies with the requirements required by the competent authority for the area of ​​use.

Safety of the drug for the species

Interpretation of the section for hydraulic use: the safety of use of the 25 cm 3-way tap is linked to the correct separation of the channels and the management of the hydraulic connections to minimize the risk of cross-contamination. To ensure the safety of water intended for human consumption, the dedicated third passage must remain isolated from the untreated distribution network and must be connected only to properly designed and maintained treatment or filtration devices. It is essential that the installation is carried out in such a way as to avoid backflow: the inclusion of suitable anti-return devices, control valves and stop cocks upstream is a recommended practice to protect water quality and ensure that the drinking water channel is not exposed to accidental contamination. From a hygienic point of view, before commissioning the dedicated line it is advisable to carefully wash and purge the duct to remove any manufacturing residues or clear accumulations; the first use of the treated water must include a short waste flow to ensure complete replacement of the water present in the pipe. For the safety of users, all operations involving the opening of the hydraulic circuit or the replacement of components (cartridges, seals) must be carried out with the system stopped and under the responsibility of qualified personnel or according to the instructions supplied with the product. Keep in mind that the actual quality of the water supplied depends not only on the tap but also on the state and quality of the downstream or upstream filtration system, the maintenance of the filters and the conditions of the water system: therefore the responsibility for healthiness also falls on the correct use and maintenance of the entire system. Finally, to prevent risks of scalding, regulate the hot water loading temperature upstream and inform users about correct operating practices, particularly in installations where children or people with reduced mobility are present.

Precautions

Special precautions for use: before installation, make sure that the pressure and temperature of the system are within the operating limits envisaged for standard domestic components; in the absence of specific values ​​indicated with the product, consider the use of pressure reducers or thermostatic valves where necessary to protect the seals and the cartridge. Store the tap in a dry and protected place until assembly and handle with care to avoid damaging the external finish; Avoid using aggressive or abrasive detergents on chrome surfaces as they can dull or scratch them. For installation, remove any debris or particles in the piping before connecting the tap to prevent the entry of materials that could clog the third passage or damage the cartridge. Follow the assembly recommendations: use new gaskets, do not force the fittings and do not exceed the tightening torque to avoid deformations. The people carrying out the installation must have the appropriate tools and, if necessary, contact a qualified technician to ensure the correct connection of the three lines (hot, cold, filtered) and possible integration with under-sink filtration systems. Cleaning precautions: use soft cloths and neutral detergents; avoid solvents, acids or products containing chlorine in high concentrations which could compromise the finish and elastomeric materials. In the event of obvious leaks or abnormal functioning, stop use and proceed with a check by expert personnel: do not repair the tap with improvised solutions that could compromise the safety of the water system. Keep the product out of the reach of children before and during installation and ensure that dismantled parts are not left available to inexperienced people. Finally, to reduce the risk of contamination, do not use the third channel for purposes other than the supply of water intended for human consumption without first having properly cleaned and inspected the system.

Method of administration

Installation and use methods: for correct installation of the 25 cm 3-way tap, proceed as follows in a general way, always adapting the operations to the characteristics of the support surface and the local plumbing system. 1) Prepare the mounting surface by drilling a hole of the appropriate size for the body of the tap; check that the thickness of the top and the space underneath allow the passage of the pipes and the installation of the fixings. 2) Before connection, clean the internal piping by removing any debris and ensure that the upstream stop valves are closed. 3) Insert the tap body into the hole, apply seals and tighten the lower fastening according to the instructions to ensure the stability of the tap; avoid excessive tightening which could deform the seals. 4) Connect the hoses: typically the left line corresponds to the hot, the right to the cold and the third connection to the filter/dedicated line connection; respect the correspondence and use suitable fittings and new gaskets. 5) Gradually open the supply valves and check for any leaks; also check the joints of the third channel. 6) To connect to the filtration system, follow the filter manufacturer's instructions: in general it is advisable to purge the dedicated line for a few liters before using it for food to remove residues and air. 7) Check the functionality of the mixing lever and the dedicated passage: open the dedicated mouth and check that the dispensing is independent and free from mixing with the mixed water. 8) Provide users with basic information on operation, indicate how to operate the lever to obtain filtered water and how to avoid sudden movements that could stress the pipes. Daily use: avoid using the tap as a discharge point for incompatible liquids; To obtain drinking water from the dedicated channel, always keep the circuit clean and maintained. In case of replacement of the cartridge or internal interventions, cut off the water supply, empty the circuit and proceed with caution according to the instructions of the assistance service or the technical manual.

Treatment program

Maintenance and periodic checks: to ensure long life and optimal performance of the 25 cm 3-way tap it is important to follow a regular maintenance programme. Monthly checks: visually check the absence of leaks around the body, joints and fittings; observe any dripping from the mouth or base of the lever which would indicate worn seals or cartridges that need replacing. Ordinary cleaning: clean the external surfaces with soft cloths and neutral detergents weekly or as needed, avoiding aggressive products. Descaling: if the local water is hard, carry out a quarterly inspection of the filters and passageways; limescale deposits can reduce the flow rate and compromise the seals. Component replacement: the ceramic cartridge or the dispensing mechanism may require replacement at variable intervals depending on the use and quality of the water; monitor the behavior of the lever and the presence of drips and plan for replacement when signs of wear are observed. For the third channel connected to filtration systems, follow the filter manufacturer's schedule for replacing filter cartridges; the quality of the water supplied by the dedicated channel depends to a large extent on the maintenance of the treatment system. Annual inspections: at least once a year carry out a thorough check by a qualified technician which includes checking the seals, preventive replacement of O-rings if necessary and internal inspection of the dedicated duct for any deposits or accumulations. In the event of malfunctions or unexpected failures, suspend use until repairs are carried out; use only original or compatible quality spare parts to maintain the integrity of the system. An adequate treatment program extends the life of the tap, preserves the quality of the water supplied and reduces the risk of costly emergency interventions.
