Emergency Multnomah County Septic Services

Septic problems don’t always happen at convenient times. Lil’ Stinky offers 24/7 emergency septic services for urgent system problems. If you’re experiencing a backup, septic alarm, unusual odor, pooling water, or another serious issue, contact our team for help.

Septic Alarms

A septic alarm can indicate that wastewater levels are higher than normal or that another component of your system needs attention. If your alarm activates, reduce unnecessary water use and contact Lil’ Stinky so we can help determine what’s happening.

Sewage Backup

Water or wastewater coming back through toilets, showers, tubs, or drains is a sign that something isn’t working properly. Because backups can have several causes, identifying the source of the problem is an important first step.

Foul Odors

Persistent sewage odors inside your home or around your property can indicate a problem with your septic or drainage system. If the smell is new, strong, or doesn’t go away, it’s worth having the system checked.

Pooling Water Near Your Septic Tank

Standing water, soggy soil, or unusually wet areas around your septic tank or drainfield can indicate a septic problem. Avoid driving or placing heavy equipment over the affected area and contact a septic professional for help.

FAQs About Multnomah County Septic Services

How often should I have my septic tank pumped in Multnomah County?

Many septic systems are inspected and pumped approximately every three to five years, but there isn’t one schedule that works for every Multnomah County property. Household size, water usage, tank capacity, system type, and the amount of solids entering the system can all affect pumping frequency. Lil’ Stinky can help you determine an appropriate maintenance schedule for your system.

Slow drains, gurgling plumbing, sewage odors, wastewater backups, septic alarms, or unusually wet areas near your tank or drainfield can indicate that your system needs attention. Because these symptoms can have several causes, a professional evaluation can help determine whether you need pumping, drain cleaning, repairs, or another service.

Your septic system relies on biological processes to break down waste, so it’s important to be mindful of what enters it. Use septic-safe cleaning products as directed and avoid pouring excessive amounts of harsh chemicals down your drains. If you’re unsure whether a product is appropriate for your system, ask our team during your next service appointment.
