Did you know that correctly set water pressure can save up to 30% on consumption costs? Honeywell pressure reducing valves offer a simple way to optimise water use while protecting your installation.
High water pressure in pipework causes several issues. Above all, it leads to unnecessarily high consumption – at higher pressure, more water simply flows than is needed. Another problem is noise in the pipework caused by turbulent flow. In addition, high pressure accelerates wear on valves, fittings and seals. Last but not least, it poses a risk of damage to sensitive appliances such as washing machines, dishwashers or hot water cylinders.
Practical tests clearly show the saving potential when pressure is set correctly. If you reduce pressure from the common 6 bar to 4 bar, you save 19% of water. Reducing it to 3 bar achieves savings of as much as 29%.
For an average household, a 25% saving means reducing annual water costs by several thousand Czech crowns. For normal use, just 1–2 bar is sufficient, while mains pressure is often 4–8 bar. This excess is needlessly “wasted” through higher consumption.
Honeywell D06F pressure reducing valves
Basic pressure reducing valves from the D06F range are designed for family homes and smaller buildings. They offer flow sizes from DN15 to DN50 and are characterised by easy installation, reliability and an affordable price.
Pressure reducing valves with a fine filter perform a dual function – they reduce pressure and at the same time filter out impurities. This protects the entire installation and extends the service life of all downstream equipment. Maintenance is straightforward thanks to easily cleanable strainers.
For large buildings such as apartment blocks, offices or hotels, automatic backwashing filters are intended. They operate automatically with minimal maintenance and eliminate the need for manual cleaning.
The immediate effects of installing a pressure reducing valve include reduced noise thanks to quieter water flow, stable pressure ensuring consistent performance of showers and taps, and equipment protection leading to a longer service life for valves and fittings.
Long-term savings include lower water bills with savings of 15–30%, fewer repairs due to reduced system wear, and greater comfort thanks to stable water parameters.
A pressure reducing valve should be installed downstream of the water meter on the incoming supply pipe, upstream of the building’s distribution network. It is important to install it with isolating valves for easy maintenance. It is also advisable to fit a Honeywell filter upstream of it.
Recommended pressure values are 2–3 bar for family homes, 3–4 bar for apartment buildings, and typically 2–4 bar for commercial buildings depending on specific requirements.
Downstream of the valve, it is necessary to leave a straight pipe run with a length of five times the pipe diameter. For pressure monitoring, install pressure gauges and regularly check and clean the filters.
An example calculation of savings for an average household: with annual consumption of 120 cubic metres of water at a price of 100 CZK per cubic metre, and savings of 29% when reducing from 6 to 3 bar, you achieve annual savings of approximately 3,500 CZK. The payback period is therefore just 6–12 months.
Additional savings include lower costs for repairs to pipework and fittings, longer service life of water-connected appliances, and energy savings on water heaters – less water means less energy required for heating.
Pressure reducing valves are one of the quickest ways to reduce a building’s operating costs. The combination of savings on water, energy and maintenance makes this investment a very cost-effective solution.
