1. What stainless steel material do you use? Is it corrosion-resistant?

Our housings are made of food-grade 304/316 stainless steel, offering excellent corrosion resistance, high-temperature tolerance (≤75°C), and oxidation resistance, suitable for potable water and industrial applications.

2. Are your products compatible with filter cartridges from other brands?

Yes, they support industry-standard cartridges (e.g., 2.5"x10", 4.5"x20") and work with common media (PP, activated carbon). 

3. Do I need a professional for installation?

Installation must be performed by a licensed plumber to comply with local plumbing codes. A pressure release valve is required (operating pressure: 100–1,500 psi).

4. How often should I replace the filter cartridge?

We recommend replacement every 6–12 months, or immediately if water flow decreases or taste deteriorates. Actual frequency depends on water quality and usage.

5. What are the operating pressure and temperature ranges?

Standard operating pressure: 100–1,500 psi; Temperature range: 0–75°C (frost protection required below 0°C).

6. Where can these housings be used?

Suitable for residential (kitchen/bathroom), commercial (hotels/restaurants), and industrial applications (food/beverage, pharmaceuticals, water treatment plants).

7. Do you have industry certifications?

Our products are ISO 9001 certified.

8. How to prevent housing cracking in freezing conditions?

Install insulation or heating tapes. Drain all water when idle. Operating temperature must NEVER drop below 0°C.

9. Can I request custom sizes or connection types?

Yes, we support OEM customization (e.g., flange/threaded ports, lengths: 10"-40"). Contact our sales team for minimum order quantities (MOQ).

10. What is your warranty and after-sales policy?

We supply 1 year warranty. We provide technical documentation, installation support, global service, and year-round supply of replacement parts (O-rings, clamps).
