I was referred to AOS, and it's the best one I've ever had! Replaced my failed home sewage pump on the same day in record time. With competitive costs and great service, I'll never use anyone else. A true "customer service" business!
We have used these guys a few times over the years. This last experience was even better than the great service we’ve had in the past.I briefly explained my problem, they worked out a schedule to be here the next day.Amanda was great, but I have to give a huge thanks to Josh. He remembered us from a few years past, identified my issue quickly and gave me great advice to solve it quickly to avoid bigger issues later.I highly recommend them!!Thanks again.Chad BurnettNewberg

So grateful to Jim & John who came to the house. The lady on the phone listened, asked a few questions about the clean out pipe and yard. Drains had been working all day then did a load of laundry in the evening and suddenly everything is backing up. We made a few calls around immediately the next morning when it was obvious we couldn't clear it ourselves. American came to the house a few hours later, friendly, helpful, didn't just do the job but took the time to review out septic maintenance practices so they could get a good idea of how it may be flowing, or not, and why. Got the clog cleared and came in considerably less $ than I expected to pay. Definitely will call them again, just hopefully not too soon. Thank You!

If anyone ever needs septic system help these are the people to call. We had a recent septic emergency. A company we had used before pumped the tank. Within 3 days tank was full again. The "X" company we had used to pump tank told us drain field needed replaced, an 8K-16K expense.A friend suggested we call Dave at American On Site to get a second opinion. What a different story, he confirmed that our drain fields were fine and within a short time had men out that cleared the blockage to drain field and did a simple repair on septic tank. Total bill was extremely reasonable. I never do reviews, but for Dave I needed to take the time as he kept us from emptying our bank account for repairs not needed.

When do you need septic services?

  • Pooling water in your backyard
    Seeing water around your yard should prompt you to contact a septic service.
  • Unusual smells
    An overpowering, sickening odor emanates from septic tanks that are full or blocked.
  • Clogged drains or slow drains
    Slow drains are not only inconvenient, but they might also indicate septic issues.
  • You Notice Sewage Backup
    Full septic tanks can lead to sewage backups that can be damaging and hazardous.
  • Pumping Your Tank Is Overdue
    When you haven’t pumped your tank in a while, hire a professional.
  • Regular gurgling sounds
    Sinks and toilets gurgling might be a sign that your septic tank cannot handle more wastewater.

How often should a septic tank be serviced?

A tank’s efficiency depends on how well it is maintained. Septic tank systems will need periodic service and pumping based on their size and usage. Generally, inspections occur every 1-3 years, but they vary by region.

Maintaining septic tank involves de-sludge, pumping, and servicing it every three to five years. Because your septic tank collects wastewater from all the toilets, sinks, faucets, dishwashers, and washing machines in your home, your septic tank has an extremely challenging job to perform.

Some signs that you need septic system service in Molalla include the following:

  • Backflow of water and sewage into the home’s plumbing from sinks, toilets, and drains
  • Slow Drainage
  • Gurgling Noises from Sink and Toilets
  • Moist areas near or above the septic tank or drain field.
  • Foul smell near the septic tank or drain field

Servicing a septic tank involves de-sludge, pumping, and maintenance in every three to five years.

  • The stench, which may be present inside or outside your home, may be caused by several factors. If you smell something, it can come from a roof vent pipe or another location that permits the system pressure to balance. These vents may occasionally become clogged and blocked.
  • You may also notice an odour inside your home or near the septic system if your drain field is not functioning properly. Soil that is soft, moist, or spongy surrounding your drain field is a good sign that something is wrong with the system.
  • Remotely determining the precise source of an odour is not possible. To solve the problem, the EPA advises that you contact a local plumber and septic system service in Molalla provider.
