Clack (V1390-1700)-C-Series 1" DLFC Washer 17.0 gpm
1" DLFC Washer 17.0 GPM
Precision-engineered drain line flow control washer for Clack V1390-1700 valve systems, calibrated to 17.0 gallons per minute for optimal backwash and regeneration cycles.
Flow Control During Regeneration
Precise Flow Regulation
Controls drain line flow to exactly 17.0 GPM during backwash and brine draw cycles, ensuring complete resin bed cleaning without wasting water or salt.
OEM Replacement Part
Genuine Clack component designed specifically for V1390-1700 valve bodies, maintaining factory specifications and performance standards.
Optimized Regeneration
Calibrated flow rate prevents channeling in the resin bed while maintaining proper contact time for effective regeneration chemistry.
1" Standard Size
Fits standard 1-inch drain line connections common in residential and light commercial water softener installations.
Clack Valve Systems
This DLFC washer is engineered for Clack C-Series control valves, specifically the V1390-1700 model range. Verify your valve model number before ordering. Compatible with Clack WS1, WS1.25, and WS1.5 softener systems using 1-inch drain line configurations. This 17.0 GPM flow control washer is typically used in systems with 1.0 to 1.5 cubic foot resin tanks requiring moderate backwash flow rates.
Inspection and Replacement Schedule
Visual Inspection
Check washer for wear, calcium buildup, or deformation during routine valve service or if regeneration cycles become irregular.
Replace If Damaged
Replace immediately if flow rates drift, backwash becomes ineffective, or physical damage is observed during valve disassembly.
Preventive Replacement
Consider replacement during major valve rebuilds or if you notice inconsistent regeneration performance over time.
Factory Calibrated
Pre-set to 17.0 GPM flow rate for consistent regeneration performance
Durable Construction
Engineered polymer resists chemical degradation from brine and regenerant solutions
Simple Installation
Direct replacement component requiring only basic hand tools and valve disassembly
