The cartridge nobody else can find? We've been finding them since 2004.

Replacement diverter and volume control cartridges for luxury and discontinued shower valves - identified by real people and shipped across Canada.

• Experts since 2004 • Ships Canada-wide • GTA

Signs your diverter or volume cartridge is wearing out

Water from 2 places at once
Tub spout keeps running when you switch to the shower.

Weak flow at one outlet
Rain head, handheld or body sprays lose pressure.

Stiff or loose handle
Hard to turn, won’t stay in position, or won’t fully shut off.

Drips that won’t quit
An outlet that should be off keeps dripping.

Replacing just the cartridge is usually far cheaper than opening the wall to replace the whole valve.
