Maintenance of boiling water tap
A boiling water tap is an investment in daily comfort, and naturally you want to enjoy it care-free for years to come. Fortunately, boiling water taps require little maintenance and are designed for sustainable use. Still, there are a few maintenance tips and tasks that will ensure your boiling water tap continues to perform optimally and remains hygienically clean. On this page, you can read how to clean and descale your boiling water tap and extend its lifespan, plus what PureAqua can do for you in terms of maintenance.
Daily use and cleaning
In daily use, it is particularly important to keep the tap clean and dry. Wipe the tap regularly with a soft cloth, especially after drawing boiling water. Drops of boiling water can leave behind small limescale deposits as they dry. By drying the tap immediately, you prevent white spots and the accumulation of limescale residue. Preferably use a mild cleaning agent or simply warm soapy water. Avoid aggressive cleaning products or scouring agents, as these can damage the finish (such as chrome, stainless steel, or black coating). A microfiber cloth works perfectly for buffing away fingerprints and water spots, ensuring your tap stays beautifully shiny.
Also, clean the nozzle (aerator) of the tap. Small mineral or dirt particles can collect here over time. For many boiling-water taps, you can unscrew the sieve/aerator at the end of the tap. Rinse it off or let it soak in white vinegar for a while to remove any limescale. Rinse it thoroughly afterwards and screw it back on. This keeps the water flow steady and prevents splashing.
Descaling the water heater and tap
Just like with a kettle, limescale can build up in the boiling water tank and inside the tap after prolonged use, especially in regions with hard water. Although the water in the Netherlands is reasonably soft, some limescale buildup is inevitable. Descale regularly to maintain efficiency and water quality.
How often? That depends on the hardness of your water and whether you use a filter. With a good filter system (such as PureAqua's osmosis filters), limescale is virtually nil, in which case a check once a year is sufficient. Without a filter in a hard water area, you can perform a light descaling every ~3–6 months.
Descaling steps
A special descaling agent or vinegar is often used. Switch off the boiler and let it cool down slightly. Then, let a solution of descaler or cleaning vinegar and water soak in. For example: fill the boiler with a mixture (follow the descaler manufacturer's instructions). Let it stand for a few hours to dissolve the limescale. Afterwards, rinse the system thoroughly with clean water. Don't forget to also soak the aerator/sieve in vinegar; that is a place where a lot of limescale builds up. Tighten everything back up afterwards and switch the boiler on. Important: always consult the manual for your boiling water tap for specific instructions, as the procedure may vary by brand. Some brands (such as Quooker) offer their own descaling kits.
If you have had professional maintenance performed, the technician will also descale it. During a service visit, PureAqua's technicians can open the boiler (if necessary) and clean it thoroughly. However, this is often only necessary after years of intensive use, especially if you perform light descaling yourself in the meantime.
Replace filters
When should the filters be replaced?
Many boiling water taps, especially those from PureAqua, are equipped with filters. This can be a simple carbon filter that removes tastes and odors (such as chlorine) from the water, or an advanced osmosis filter that removes virtually all contaminants. Replacing filters in a timely manner is crucial for consistently pure water.
How often you need to replace them depends on the filter type and usage. In general:
Carbon/sediment filters
replace every 6 to 12 months (or after a certain number of liters, often 1500-3000L). This filters out, among other things, chlorine, organic substances, and fine particles.
Reverse osmosis membrane
every 2 to 3 years (this one has a longer service life, but have it replaced if TDS levels rise or flow rate drops).
CO₂ cylinder (for sparkling water)
replace as soon as empty, typically after ~60L of sparkling water, see previous explanation.
PureAqua systems often provide a signal when the filter becomes saturated (a light or notification via the app). You can order new filters from us. Replacing them is usually simple: you unscrew the old filter with a quarter turn and click the new one in (for modern “quick change” filters). Don’t forget to flush the system briefly after replacement (run a liter of water through it) to clear out any air and carbon dust.
Tip: Note the date of the last filter change somewhere, or stick a label on the filter with the replacement date. This will help you keep track. You will notice that with clean filters, the taste of hot water remains optimal and the flow rate stays good.

Frequently asked questions about boiling water tap maintenance
Does a boiling water tap require much maintenance?
No, in general, a boiling water tap requires little maintenance. The system is designed to perform daily without constant attention. The most important thing is to keep the tap clean (wipe it down regularly to prevent limescale) and replace filters on time, if applicable. Descaling is only necessary occasionally, depending on the hardness of your water. Many users get by with a small annual cleaning and filter change, nothing more. It is therefore certainly not as intensive as, for example, maintaining a coffee machine. As long as you do these basic things, the tap will usually continue to work without any problems.
How do I prevent limescale in my boiling water tap?
The best way to prevent limescale is byfiltering the water. If you use a water filter or softener, you reduce the hardness and limescale deposits will hardly occur. If you do not have one, regular cleaning helps: dry the spout after use, clean weekly with a mild descaler (a cloth with vinegar along the spout, for example). Soaking the aerator in vinegar every few months also keeps the flow free of limescaleheetwaterkraan.com. Furthermore, you can preventively set the boiler to a slightly lower temperature (e.g., 100°C instead of 110°C, if adjustable), although this is neither necessary nor possible with most boiling water boilers. Conclusion: filter use and cleaning are the key. Incidentally, PureAqua's own systems are often already equipped with filters, so limescale has practically no chance.
When should I replace the filters of my boiling water tap?
This varies by system, but a good rule of thumb is:every 6-12 monthsto replace the filters. For carbon or combination filters, 12 months is usually the maximum for optimal performancejudithvandenboom.nl. With intensive use or very contaminated supply water, sometimes as early as 6 months. An osmosis membrane lasts longer, often 2-3 years. Many boiling water taps will have an indicator (for example, a change in LED color, a beep, or a notification in the app for advanced models) that indicates the filter is becoming saturated. If you notice the taste of the water changing or the flow rate decreasing, that is also a sign that the filter needs replacing. At PureAqua, you can order individual filter cartridges. We even offer subscriptions or a reminder service so that you automatically receive new filters on time and don't forget. By replacing them on time, your water quality remains top-notch and you prevent unnecessary strain on the boiler from potential dirt particles.
My boiling water tap flow is slowing down, what should I do?
Reduced flow may indicate blockage or calcification. First, check the aerator for blockages – this is located at the spout. Unscrew it and clean out any dirt or limescale (soaking it in vinegar overnight often helps). Then, screw it back on and see if the flow has improved. If that does not help, the filter may be saturated (in filtered systems); replace the filter and test again. In hard water areas, the inside of the tap or boiler may also be calcified. In that case, descaling is required: follow your system's instructions to flush the boiler with descaler. Always ensure you rinse thoroughly with clean water afterwards. If the flow still does not improve, there may be another issue (e.g., a faulty tap valve). In that case, it is best to call our service department – we will help you diagnose the issue further or schedule a technician if necessary. However, in most cases, the problem is resolved by cleaning the aerator or replacing the filter.
