The Watts 0876175 is a genuine factory OEM restoration repair kit designed explicitly for 3/4-inch N35B and N35BU water pressure reducing valves. This drop-in maintenance kit provides all internal structural parts necessary to rebuild the valve assembly, eliminating downstream pressure creep and restoring smooth volumetric flow control without requiring expensive body de-soldering or plumbing alterations.
Comprehensive Hardware Overhaul Components Included:
- High-Flexibility Fabricated Diaphragm: Formulated from premium elastomer compound reinforced with fabric threading to ensure linear response profiles against incoming supply pressure spikes up to 300 PSI.
- Replacement Seat & Disc Module: Includes a fresh, precision-ground seating surface and matching rubber disc assembly to establish an absolute drip-tight seal when downstream demand shuts off, safely preventing system over-pressurization.
- All Vital O-Rings, Washers & Friction Rings: Packaged complete with upgraded static and dynamic seals to isolate water channels, ensuring smooth, friction-free movement of the internal stem assembly.
Installation Tip: Before opening the regulator spring cage to install this kit, ensure the upstream water main is completely shut down and downstream static line pressure has been fully bled off through a nearby fixture. Clean the interior bronze valve body thoroughly of all scale or mineral debris before dropping in the new cartridge parts.
