General Ecology® contaminant reduction claims are based on 1 gpm flow rate. In determining the performance requirements for the Neo-Pure NP-1SG Seagull Compatible cartridge, we contracted WQA laboratories to independently test the Seagull® IV X-1 System with the Seagull® RS-1SG(CA) filter cartridge using NSF testing protocols. Surprisingly, we discovered:
1. The Seagull® IV X-1 filter system does not have a flow control.
2. The Seagull® filter has a flow rate of 1.32 gpm! 25% over their claim.
We strongly urge retrofitting all Seagull® IV X-1 Systems with a flow control to limit the flow rate not to exceed 1 gpm to attain the contaminant reduction claims made by General Ecology (RS-1SG) and/or Neo-Pure (NP-1SG).We recommend the Neo-Pure 1 gpm Flow Control Kit which includes the following items:
- 1 gpm Flow Restrictor 3/8″ x 3/8″
- 4 ft. Blue 3/8″ OD Tubing
- Two 3/8″ Brass Compression Nuts
- Two 3/8″ Plastic Ferrules
- Two 3/8″ Tube Inserts
