For this job, we addressed an issue with the Moen shower handle being difficult to pull open and push shut, which was caused by wear and internal failure of the cartridge. The existing cartridge was carefully removed and replaced with a new Moen cartridge to restore smooth operation and proper water control. All components were reassembled, and the shower was thoroughly tested to ensure correct function, proper temperature control, and leak-free operation. All work was completed in accordance with current plumbing standards.
