Responded to a dual plumbing issue involving a leaking Delta shower valve and a clogged kitchen sink drain. Upon inspection, found the shower valve cartridge was failing and causing water to leak from the handle. Replaced the Delta cartridge to restore proper function and eliminate the leak.

For the kitchen sink, diagnosed a grease blockage in the horizontal drain section before the vertical drop. The homeowner had previously attempted to clear the obstruction and noted a gel-like substance in the pipes. Used a drain auger to break up the grease accumulation, then employed a blow bag to fully clear the line and restore proper drainage. The blockage was successfully removed from the accessible horizontal pipe section without requiring extensive disassembly of the drain system.
