Water System Support: Frequently Asked Questions
This depends on your flow rate, pressure, and required filter capacity. We can help calculate the right size based on your site’s operating conditions.
Single-cartridge housings suit lower flow rates and are easy to service. Multi-cartridge housings accommodate higher flows and reduce pressure drop across larger systems.
Stainless steel is recommended for high pressure, temperature, or chemical compatibility. Plastic housings may be suitable for lighter-duty or low-cost applications.
Yes. Most housings are compatible with multiple cartridge types including sediment, carbon, and membrane filters. Just ensure end-cap style and length match.
Many of our filter housing models meet WRAS and other UK water safety standards. Contact us for documentation and compatibility details.
