FAQ about myBach drinking water fountains and dispensers

Fully check the delivery contents before beginning installation. If parts are missing or delivered damaged, document this with a photo, the drinking fountain's serial number, and a precise description. Inspect the goods as soon as possible after receipt, ideally while the carrier is still present. Visibly identifiable transport damage should be documented immediately upon delivery on the delivery note and reported to the delivery person. Concealed damage, discovered only upon unpacking, should be reported immediately. Damage reported more than 7 days after delivery can usually no longer be reliably settled through the carrier.

If no monitoring data is displayed, first check if the monitoring module is powered and if all relevant connections are properly seated. Then, verify that the module has been set up and that data transmission is active. Since the monitoring setup can vary depending on the version and configuration, if the error persists, please contact support with the serial number, a brief description of the issue, and ideally a screenshot.

Not necessarily. An unusual sample can have many causes: the supply line, stagnation in the line before the well, the well's installation, the sampling process, external contamination, or inadequate flushing. Therefore, a systematic investigation should be carried out: checking the line leading to the well, the connection, the well itself, flushing, disinfection, and re-sampling.

The drinking water system should be regularly flushed with a suitable cleaning or disinfectant (hydrogen peroxide or chlorine dioxide). Afterwards, the system must be flushed with fresh drinking water for several minutes. This is particularly important during commissioning, maintenance, or in the event of unusual sampling results. Before installing a drinking water fountain, the hygiene instructions should be carefully observed, as many contaminations arise from unprofessional or unhygienic installation.

The casing should be cleaned regularly to reduce dirt buildup and ensure the stainless steel surface remains protected long-term. Prolonged exposure to road salt should be avoided, as salt can also corrode stainless steel surfaces. V2A steel primarily consists of chromium and nickel. V4A additionally contains about 2 percent molybdenum, making it more resistant to chloride-containing media, acids, and road salt. Therefore, V4A is the more robust choice for coastal areas, saline environments, or particularly demanding locations.

After installation, five points should be checked: First: Hold your hand in front of the sensor – water must start within approximately three seconds. Second: Remove your hand – water must stop within approximately one second. Third: If continuously activated, the water must stop after approximately 60 seconds. Fourth: The automatic hygiene flush must function. Fifth: The water must drain correctly over the housing, outlet, drain plate, and pipe.

In case of leaks, check all plug and hose connections, the Geka-Plus couplings, the ball valve, the pressure regulator, and the connection to Module B. During commissioning, each connection should be actively checked for leaks and corrected if necessary. Not all connections can be retightened. Some connections have adhesive seals. If it is visibly an adhesive seal, it should not be pulled or twisted. In this case, the component should be professionally inspected or replaced.

The Bach is connected as standard via a Geka-Plus quick coupling. It is important that the coupling is seated correctly and fully locked. Upon customer request, a G1/2-inch threaded connection can be provided as an alternative.

Both options are possible. A soakaway pit or drainage system may suffice if the location is suitable. A site-specific wastewater connection is often recommended, especially for heavily frequented public locations. Reliable water drainage is crucial. For the self-sufficient version, it's particularly important to carefully check if the infiltration system has sufficient capacity. Otherwise, a wastewater connection is the safer solution.

The rigid construction requires a depth of approximately 122 cm. For the version with monitoring, it's about 132 cm. If a pressure reducer is also used, additional space should be planned. A depth of about 160 to 180 cm is recommended. 2 meters is certainly sufficient in any case.

The base must be perfectly level and flush with the ground at its top edge. If the base is crooked, the housing might be misaligned, the water arc could be unfavorable, and drainage might function poorly. Therefore, a stable concrete foundation is recommended. The correct alignment of the upper edge of the base is crucial.

Check if the drain hose is correctly positioned around the drain plate. The drain plate must be centered so that the sides of the drain hose enclose the plate. If it is not properly installed, water can be misdirected.

If water is pooling on the ground, check the drainage. The water must be drained in a controlled manner via a sewer connection, drainage, or a soakaway. Especially in public spaces, the drainage system should be designed to prevent puddles, slipping hazards, or contamination. Also check if the water jet is correctly adjusted and lands approximately 8 to 12 cm in front of the outlet on the casing - not on the ground.

A small amount of water discharge from the drain valve is normal. Up to approximately 160 milliliters can exit the drain valve per use. During use or flushing, the drain valve may briefly discharge or drip water at the beginning. Residual water may exit for a few seconds to minutes after completion until the lines are empty. This water must drain away to prevent stagnant water from remaining in the line. It is important that this water is cleanly discharged via drainage, a soakaway, or a wastewater connection.

The self-sufficient Bach-Version uses water movement for power generation and operates with regular flushing. This results in higher water consumption than a purely battery-powered version. The hygienic advantage: The pipework is regularly flushed and moved. This reduces stagnation and supports safe, hygienic operation.

The self-sufficient version requires sufficient water pressure and flow to generate electricity. Therefore, first check the pressure at the connection point. Then, check if the water flow is too restricted by closed taps, incorrect couplings, constrictions, or an incorrectly set pressure reducer. If other faults are ruled out, the source of the problem may lie in the power generation itself. In this case, Module A should be sent in for inspection or repair.

For the battery-powered version, first check the battery status. Standard batteries need to be replaced regularly, typically about once a year, depending on usage and location conditions. Also, check if the AA batteries are inserted correctly into the box and if the battery box is properly connected to the sensor.

The automatic hygiene flush should be triggered regularly. First, check the power supply. For the Bach battery version, check the battery status. For the self-sufficient Bach version, check the power from the rechargeable battery. In both cases, the red plug is relevant, as the power supply can be checked there. Furthermore, the timing logic starts once the power supply is connected. If the power supply was interrupted, the cycle restarts.

No. This is a safety feature. If the sensor is continuously activated, water dispensing automatically stops after approximately 60 seconds. This prevents misuse and unnecessary water consumption.

After removing your hand from the sensor, the flush should stop within approximately one second. If this does not happen, check the sensor, plug connections, and control valve. If continuously activated, the system must automatically shut off after approximately 60 seconds. If it does not, there is likely an electrical or valve malfunction. Document the behavior with a photo or video and report the case, including the serial number and a description of the fault, to support.

First, check the distance to the sensor. Your hand should be approximately 2 to 15 cm in front of the sensor. If nothing happens, check the plug connections: The red sensor plug must be connected to the red plug, and the black sensor plug to the corresponding plug from Module B. For the battery version, the battery status should also be checked. You can tell if the sensor is receiving power because an LED in the sensor will briefly light up as soon as the red plugs are connected.

If the water jet is too strong, the pressure is usually too high or the pressure regulator is incorrectly set. Adjust the pressure on the pressure regulator with a screwdriver until a clean, even arc of water is produced. The arc of water should hit the casing approximately 8 to 12 cm away from the outlet.

If the water jet is too weak, first check the water pressure. The self-sufficient version requires a static pressure of at least 3 bar and a flow pressure of at least 2.7 bar. The battery version requires a static pressure of at least 2.2 bar and a flow pressure of at least 1.5 bar. If the pressure is below these values, a clean water arc cannot be formed. Also check if the ball valve is fully open and if the pressure regulator has been set correctly.

Yes, the hygiene flush can be tested. It's important to note: The flush cycle begins as soon as the power supply is connected. Therefore, you should wait at least an hour and then observe the fountain. If the automatic flush does not trigger, check the power supply, plug, sensors, and control unit.

A suitable bit is supplied for the security screws of the maintenance flap. It is a 1/4-inch TX 25 x 25 mm bit with a security pin hole. This bit should be kept securely by the operator or service personnel so that the maintenance flap can be opened during service work.

For the seasonal variant (Bach-S), the fountain is taken out of service before frost. To do this, the internal components, especially Module A and Module B, are removed via the inspection hatch. The water-carrying parts must drain completely, dry, and be stored in a frost-free environment. If possible, hose C and Module C should also be emptied. The goal is to ensure no water remains in the system, as this could damage components due to frost and become contaminated during long periods of inactivity.

Hydrogen peroxide and chlorine dioxide are particularly well-suited for disinfecting drinking water fountains, as both agents can be used for the hygienic cleaning of water-bearing systems. It is important to use only disinfectants that are suitable and approved for drinking water applications. Dosage, contact time, and subsequent flushing with fresh drinking water must always be carried out according to the manufacturer's instructions and within the scope of the respective hygiene plan. After disinfection, the drinking water fountain should be thoroughly flushed for several minutes before it is used again.

The water-bearing parts should be disinfected at least as part of regular maintenance and additionally as needed – for example, after a prolonged period of inactivity, after work on the system, or in case of unusual sampling results. After disinfection, it must always be thoroughly flushed with fresh drinking water. The exact interval should be defined in the operator's hygiene plan and, if necessary, coordinated with the health authority.

V4A stainless steel is more corrosion-resistant than V2A and is particularly suitable for more demanding locations. Nevertheless, V4A should also be cleaned regularly. As a guideline, about 2 to 3 cleanings per year are recommended – especially after winter or when visible soiling occurs.

For V2A stainless steel, about 4 to 5 external cleanings per year are recommended. Cleaning after winter is particularly important, as road salt, dirt, and deposits can accumulate on the surface. Regular cleaning protects its appearance and reduces the risk of flash rust or superficial discoloration.

For a stream without hygiene monitoring, Module C is typically used. If the stream is equipped with HyMo (hygiene monitoring), Module Z is used instead of Module C. Module Z contains part of the sensor technology. If hygiene monitoring is retrofitted, Module C can be replaced by Module Z. Depending on the configuration, both can also be included in the planning.

A suitable manhole pipe is required for the substructure. The relevant range is an inner diameter of at least 28 cm and an outer diameter of no more than 35 cm. It is important that there is sufficient space for the module technology, hose routing, and future maintenance access.

Generally, installation without a deep pit is possible if a customized special solution is planned. However, this is not a standard installation. In such cases, water management, drainage, frost protection, wastewater, accessibility, and structural integrity must be individually assessed. For most locations, the regular underground installation remains the cleanest and most reliable solution.

The seasonal variant (Bach-S) has a shallower installation depth than the year-round variant. A minimum of about 80 cm should be planned for, but approximately 110 cm or more is better. Here too, the rule applies: those who plan too shallowly will complicate maintenance, emptying, and future work on the system.

For a year-round stream, the pit should be at least about 130 cm deep. 160 cm or more is better, as this provides enough space for underground technology, hose routing, drainage, and potentially monitoring or pressure reducers. Pits planned too shallow often lead to unnecessary installation effort later on.

Yes, a switch to battery operation is generally possible. This is particularly relevant if water consumption needs to be reduced or if the site conditions are not ideal for a self-sufficient power supply. The conversion should be technically reviewed beforehand and not improvised independently, as the power supply, sensors, and modules must be coordinated.

For the battery-powered version (Bach-B) and the seasonal variant (Bach-S), water consumption is significantly lower than with the self-sufficient version. During use, it is approximately 2 liters per minute. Additionally, the automatic hygiene flush consumes about 48 liters per day. These variants are particularly appealing if minimizing water consumption is a key decision criterion.

The Bach-E (energy-autonomous) uses water movement for its self-sufficient power supply. Consequently, consumption during use is approximately 7 liters per minute. In addition, the automatic hygiene flush leads to a daily consumption of about 168 liters. The benefit: The water in the line is regularly moved and flushed, which supports hygiene and reduces stagnation.

With the Bach-E, the energy-self-sufficient version, significantly more water can exit from Module A at the bottom compared to other variants. This is not necessarily a problem. This water is used for electricity generation. The only important thing is that the water is drained in a controlled manner via a drainage system, soakaway, or wastewater connection, and does not accumulate uncontrollably in the excavation pit or on the ground.

If the pressure regulator no longer works or is damaged after frost, Module A should be checked. The pressure regulator is a technical component and should not be subject to makeshift repairs. In this case, Module A is sent in for repair or replaced. Especially with seasonal variants, it is important to properly decommission them before frost.

If the connection pressure is 6 bar or more, a pressure reducer must be used. This should be set to approximately 4 bar. Without a pressure reducer, components can be unnecessarily stressed, potentially leading to malfunctions or damage. The pressure reducer must be installed before the entire system, i.e., in or near Module C.

If the water jet is too strong, first check the connection pressure and adjust the pressure regulator. The goal is a clean, even water jet that should hit the housing approximately 8 to 12 cm from the outlet. In case of very high pressure, an additional pressure regulator may be necessary. For older versions from 2025, it may also be advisable to have Module A checked or modified. Newer versions are adapted to the intended pressure range.

If a powder coating appears to be a different color than expected, it should first be checked against a genuine RAL color fan. Screen displays, photos, and prints are not color-accurate. Additionally, powder coatings can exhibit material and process-related tolerances. It is also important to check whether the correct color value was specified when ordering. Please verify this on your order confirmation. Only if the actual RAL comparison shows a clear deviation should a complaint be filed.

If a screw or small part is missing from the delivery, the scope of delivery should first be checked completely. Document the missing part with a brief description and the serial number of the drinking water fountain. Depending on the component, it can be sent later or, in the case of standard screws, procured quickly by yourself. Important: Check the scope of delivery before starting assembly and not only during installation.

If rust becomes visible on the hood, it is often due to superficial deposits, flash rust, or contamination from road salt. Especially after winter, stainless steel should be thoroughly cleaned. In case of more severe discoloration, professional cleaning or pickling of the surface may be necessary. It is important to note: Road salt should not remain on the stainless steel surface for extended periods, as even stainless steel can be corroded by it.

If there's a leak, the first step is to locate exactly where the water is escaping: at a coupling, a hose, the pressure regulator, or a module. Simple connections can be tightened, re-plugged, or properly sealed by a specialist. If it's visibly an adhesive seal, it should not be pulled or twisted. In this case, the affected component should be inspected or replaced if necessary. If the leak is directly at a module or persists after sealing, the affected module should be replaced or sent in for inspection.

If no water flows despite holding your hand in front of the sensor, first check the sensor distance. Your hand should be approximately 2 to 15 cm in front of the sensor. Next, check the power supply. For the battery version, check the battery box, battery status, and the correct polarity of the AA batteries. For the self-powered version, check Module A and the power supply. Then, check the plug connections. If the sensor, power supply, and cables are in order, there might be a fault with the cable, solenoid valve, Module A, or Module B. In that case, the affected modules should be sent in for inspection.

If the unit continuously dispenses water, first check the sensor. When connecting, it should be visible if the sensor is receiving power, for example, by a brief illumination of the LED on the sensor. Then check the plug connections and the sensor cable. If the sensor can be ruled out as the source of the problem, the cause is often deeper within the system, for example, with the solenoid valve, a damaged cable, or Module B. In this case, Module B should not be opened temporarily, but rather sent in for inspection or repair. If possible, document the behavior with a photo or video, and have the serial number, delivery address, and a brief error description ready.
