Bristan DIV SB019RBRBA Brass Diverter Valve for 1901 Valves

Summary

Bristan DIV SB019RBRBA Brass Diverter Valve for 1901 Valves

The Bristan DIV SB019RBRBA is a brass diverter valve designed for use with certain valves in the Bristan 1901 range. It directs water flow between outlets such as bath spout and shower handset/spout depending on valve design.

Function

This diverter valve switches the flow path within the mixer valve body so you can alternate between spout and shower outlet when using a 1901 mixer. It replaces the original diverter mechanism in compatible 1901 bath-shower mixers.

Confirmed Compatible Models

• Bristan 1901 Bath Shower Mixer (all variants listed under model line 1901 that use the 1901 diverter mechanism)

Compatibility depends on the valve being part of the 1901 series and originally fitted with the 1901 diverter. If your mixer is from another Bristan line or uses a different diverter code, this valve will not fit.

Selection and Verification

Always check your mixer’s spare-parts diagram or existing diverter code before ordering. Because Bristan uses different valves and mechanisms across multiple ranges, parts are not interchangeable based on appearance alone.

When Replacement Is Recommended

Replace the diverter valve if the mixer fails to redirect flow correctly, leaks between outlets, or shows reduced flow or inconsistent switching between spout and handset. Installing a new DIV SB019RBRBA can restore proper flow control without replacing the entire mixer valve body.
