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
