Kohler 1013489 brass faucet stem

The Kohler 1013489 is a brass stem designed for shower trim valves. It suits homeowners or plumbers repairing Kohler Purist series bathtub and shower faucets. This new component replaces worn internal parts to restore proper water control. It is a direct-fit replacement for compatible valve bodies.

Non-CEC compliant brass construction

The stem is manufactured from brass and is not CEC compliant. In normal operation it regulates water flow through the valve assembly without electronic components. There are no moving fans, pumps or heat-generating circuits to create noise or draw power. Performance depends on the existing plumbing supply pressure.

Fits Purist series valve trims

This stem fits inside Kohler Purist series bathtub and shower faucet valves. It requires a compatible valve body already installed in the wall. The 1 1/2 inch overall length matches the original specification for these trims. No additional adapters or special tools are mentioned in the product data.

Questions about this item

How do I install the Kohler 1013489 brass stem into a Purist series valve, and what step is often missed?

Turn off the water supply, remove the handle and trim, unscrew the old stem with a deep socket, then install the new 1 1/2 in brass stem; the step often missed is lubricating the O‑rings with silicone grease before insertion.

What maintenance or replacement will the Kohler 1013489 stem need over time?

The brass stem itself is durable, but the internal O‑rings and washers will wear; plan to replace those seals whenever the shower starts to drip or temperature control becomes inconsistent.

What limit appears first when the Kohler 1013489 stem is used continuously in a high‑flow shower?

Because the stem is non‑CEC compliant, the first limit under sustained high‑flow use is the higher water consumption rate compared to pressure‑balanced, CEC‑approved alternatives.
