Flow Restrictor for All Shower Heads by HammerHead Showers, 1.75 GPM

• 1.75 GPM (Gallons Per Minute)
• California Compliant, low flow model
• Flow Regulator by Neoperl® for HammerHead Showers®
• Works with all HammerHead Showers products
• Steady flow rate regardless of pressure, optimal for households with low water pressure

The combination of the calibrated o-ring and seating area is accurately calibrated to the water pressure and ensures a steady flow rate within the indicated range.

Flow restrictors, such as the HammerHead Showers 1.75 GPM, feature a housing, seating area & precision o-ring. The o-ring shape alters with varying pressure & water flow, staying within the given flow rate tolerance. When no flow/pressure, the o-ring is relaxed (pos. 1); with flow, it's pushed into the seating area (pos. 2), the pressure increases, o-ring shape changes more (pos. 3), & as pressure decreases, o-ring shape returns to pos. 2 & 1.
