A single handle shower faucet has one handle for both hot and cold water, rather than the traditional two. These fixtures are typically found in updated, remodeled, or new bathrooms. Repairing a single handle faucet is not entirely different than repairing a double handle faucet. Typically, a leaky faucet is due to a worn out O-ring, a small rubber ring which ensures the seal between your shower cartridge and plumbing is tight. Keep in mind, this will be an ambitious task for someone unfamiliar with the work.
