We specialize in thermostatic cartridges, pressure balance cartridges, diverter cartridges, volume control cartridges, service stops, check stops, ceramic cartridges, hot and cold cartridges, and internal valve components for luxury and hard-to-find shower, tub, and faucet systems.
We carry and help source parts for brands including Watermark Designs, WaterWorks, Rohl, Dornbracht, Newport Brass, THG, Hansgrohe, Grohe, Gessi, GRAFF, JACLO, Kallista, Phylrich, Vola, California Faucets, Lefroy Brooks, Sigma Faucets, Toto, Symmons, Tempress, and more.
Need Help Identifying a Part?
Many plumbing cartridges and valve parts look similar but are not interchangeable. If you are unsure which replacement part you need, send us the brand name, model number, part number, markings, and clear photos of the existing cartridge, valve, trim, or fixture.
We help identify parts for luxury, discontinued, imported, and specialty plumbing systems so customers can repair the existing fixture whenever possible instead of replacing the entire shower or faucet system.
