Chicago Faucets 1920-023JKNF
The Chicago Faucets 1920-023JKNF is a genuine OEM Auto-Drain™ Hose Bumper specifically designed for use within the 1920 Series thermostatic and pressure-balancing shower systems. This small but essential component serves as a protective interface within the Auto-Drain valve assembly, helping to cushion internal parts and ensure the smooth operation of the automatic purging mechanism. It is a standard replacement part for the 1920-035KJKCP and 1920-235KJKCP hose assemblies, which are engineered to automatically drain standing water from the hand spray and hose to prevent the growth of waterborne pathogens like Legionella.

Expert Insight:
The 1920-023JKNF bumper is a critical "quiet" component of the Auto-Drain system. Over time, constant exposure to fluctuating water pressure and high temperatures can cause the original bumper to harden or degrade, which may lead to a clicking noise or an incomplete drain cycle. Installation Tip: When servicing the Auto-Drain valve, ensure the bumper is seated correctly within the housing before reattaching the hoses. Pro Tip: This part is often lost during the teardown of a 1920-035KJKCP hose assembly for cleaning. If your Auto-Drain valve feels "loose" or is rattling when the water is turned off, this bumper is likely missing or worn out. We recommend keeping a few on hand if you manage a healthcare facility with multiple 1920-series showers. Need help identifying where this fits in your specific hose assembly?
