The Neoperl 1/2″ PCW-01 Shower Flow Regulator (Part No. 58863910000) is a highly efficient water-control component designed to stabilise shower flow at 9 litres per minute. Using precision pressure-compensating technology, it ensures consistently comfortable showering performance while significantly reducing water and energy consumption.


Its 1/2″ connection format makes it compatible with a wide range of shower hoses, mixers and plumbing fittings, making it an excellent choice for both domestic and commercial installations.



Key Features




Consistent 9 L/min Flow Rate



The regulator maintains a steady 9 L/min flow, offering a balance between water efficiency and strong shower performance. This flow rate is ideal for users who prefer a fuller shower experience without excessive water use.



Pressure-Compensating Performance



Whether pressure rises or drops within the plumbing system, the PCW-01 automatically adjusts to maintain the target flow. This ensures users enjoy a stable, predictable shower stream throughout the day.



1/2″ Standard Connection



The regulator’s universal 1/2-inch design allows quick installation between shower hoses, mixers or internal fittings. This makes it highly suitable for easy retrofits or upgrades.



Robust and Long-Lasting Design



Made with durable Neoperl components, the PCW-01 withstands everyday use, high temperatures and hard-water exposure. It delivers long-lasting performance with minimal maintenance requirements.



Supports Hot-Water and Energy Savings



By limiting shower flow, the regulator reduces overall hot-water consumption. This results in lower energy bills and a significant reduction in environmental impact—especially valuable in homes, hotels or commercial facilities with frequent shower use.



Applications



  • Standard residential showers

  • Hotels, guest houses and rental properties

  • Gyms, leisure centres and sports facilities

  • Student accommodation and hostels

  • Commercial and workplace shower rooms

  • Buildings needing predictable water usage




Water and Energy Benefits



Unregulated showers commonly consume 12–15 litres per minute. Reducing this to 9 L/min can save up to 40% of water per shower while still maintaining a comfortable flow.


Since showers account for a major share of hot-water usage, the associated energy savings are considerable. In buildings with multiple showers, this regulator offers substantial annual reductions in both water and gas/electric heating costs.



Installation and Maintenance Notes



  • Fits standard 1/2-inch shower hose or mixer connections

  • Installation requires no specialist tools

  • Suitable for mixer, thermostatic and many electric shower systems

  • Minimal maintenance—periodic inspection ensures continued performance

  • Ideal for retrofits and quick installations
