Septic Tanks

Septic tank systems play a key role in managing household wastewater—especially for homes that aren’t connected to city sewer lines. At MCM Plumbing, we provide septic repair, diagnostics, and septic system support across Merced County and the Central Valley. Our goal is to help homeowners protect their systems with clear answers, practical options, and quality workmanship.

A typical septic system separates solids in the tank while liquid (effluent) flows to the leach field where it filters through the soil. When problems show up—slow drains, odors, backups, or wet areas—we can help locate the issue and recommend the right repair path.

Here’s what we offer:

• Septic tank and leach line locating
• System mapping with clear documentation
• Jet system cleaning, inspection, and service (advanced/aerobic systems where applicable)
• Diagnostics for drainage issues, backups, odors, and recurring clogs
• Cleanout access and hydro-jetting support (where appropriate)
• Repair planning and solutions for damaged or blocked lines (as conditions allow)

We use modern locating and diagnostic tools to identify trouble spots and reduce unnecessary digging. Whether you’re dealing with symptoms now or planning ahead, we’re ready to help.

Notice: MCM Plumbing does not provide septic tank pumping. If pumping is required, please contact a licensed septic pumping provider. We can coordinate scheduling with your pumper when needed.
