Bristan SK330048A Diverter Cartridge for 1901 Valve

Summary

Bristan SK330048A Diverter Cartridge

The SK330048A is a genuine flow/diverter cartridge for selected Bristan shower valves. It switches water flow between shower outlets (for example between shower head and handset) when fitted correctly into a compatible diverter-type valve body.

Function

The cartridge controls the internal flow path inside a diverter-type shower valve allowing the user to select which outlet receives water. It replaces the original diverter insert in valves designed for SK330048A.

Compatible Shower Valves / Models

• 1901 exposed dual control shower with diverter and rigid riser kit
• 1901 Exposed Sequential Shower Valve & Rigid Riser Kit – Chrome
• Trinity exposed dual valve with diverter and rigid riser kit

These models are listed by multiple spare-parts suppliers as compatible with SK330048A. Other models may fit if their valve diverter internals match the SK330048A geometry; always verify against the valve’s spare-parts diagram or existing diverter part code before ordering.

Selection and Verification

Before ordering, confirm that your valve body matches one of the confirmed models above or check the existing diverter cartridge code to ensure compatibility. Some Bristan shower valves use different diverter designs even if externally similar.

When Replacement Is Required

Replace the SK330048A diverter cartridge if outlet switching fails leaks occur between outputs flow diverts incorrectly or if the diverter handle becomes stiff or unresponsive. Installing a correctly matched cartridge can restore proper diverter function without replacing the full shower valve.
