Watts 0887171 Repair Kit
The Watts 0887171 (Model RK 188/288/388-T) is a heavy-duty 1/2 inch vacuum breaker repair kit engineered to restore the integrity of backflow prevention assemblies in commercial and industrial plumbing systems. For technicians dealing with backsiphonage issues or seat leakage, this kit provides a direct factory solution for Series 288A, 188A, and 388 units. The assembly features a high-grade silicone seat disc designed for chemistry resistance and thermal stability in both hot and cold water applications, rated up to 125 psi. By replacing the internal disc assembly and bonnet O-ring, contractors can ensure a full-size orifice flow and prevent polluted water from entering potable supplies without replacing the entire brass valve body. This kit is essential for maintenance on laboratory equipment and low-flow health hazard installations where atmospheric vent performance is critical to system safety and backflow prevention compliance.
Key Benefits- Direct OEM Compatibility: Specifically designed for 1/2" Watts 288A, 188A, and 388 series anti-siphon vacuum breakers.
- Durable Seal Integrity: Includes a chemical-resistant silicone disc and float assembly to handle water hammer and thermal shock.
- Simplified Serviceability: Field-replaceable components allow for rapid restoration of the atmospheric vent without specialized tooling.
- High-Performance Flow: Maintains the full-size orifice capacity required for maximum pipe flow and spill prevention.
Is this kit compatible with lead-free LF288A models?
Yes, the internal 0887171 repair kit components are designed to fit both the standard and lead-free (LF) versions of the 1/2" 288A series.
What are the signs that a vacuum breaker needs this repair kit?
Technicians should look for persistent leaking from the atmospheric vent under the bonnet or failure to seal during a backsiphonage event, usually caused by a fouled or worn disc float.
Does the kit include the bonnet and hardware?
This total repair kit includes the disc, disc float, and the critical bonnet O-ring to ensure a pressure-tight seal upon reassembly.
