JMJ Plumbing provides professional washing machine plumbing installation and repair services to help prevent leaks, water damage, and unexpected flooding. Washer hookups are one of the most common sources of household water damage when valves, supply hoses, or washer boxes fail. We install and replace washer boxes, shutoff valves, and supply lines, and can upgrade older valves to reliable quarter-turn models for improved performance and easier operation. If your drain standpipe is leaking, backing up, or not draining properly, we’ll diagnose and repair the drainage issue as well. The result is a safer, more dependable laundry setup that protects your home from costly water damage.
