Time for Septic System Inspection?

Sometimes septic system problems are obvious, and sometimes issues are harder to pin down. If you’re experiencing any of the symptoms below, a septic system problem is likely the underlying issue. Even if the issues are intermittent, a septic system inspection can prevent worse problems from developing.

Difficulty flushing
Drain & toilet backups
System alarm sounding

Sewage odor from drains
Odor in septic tank location
Spongy feeling in lawn

Property Transfer or Municipal Requirement

One contingency usually specified in property purchase and sale agreements is a septic system inspection. Meant to determine whether a system is functioning properly, the process includes a thorough examination of all the system’s components. We look for potential leaks, measure sludge levels, check for signs of backup, analyze the condition of filters and baffles, check alarms and float, and check the drainfield for signs of ponding. Our fully documented report of findings includes any recommended action for repair or pumping of your septic now.

If you need to get your septic tank replaced, you definitely need to call The Septic Group. These types of installations are quite overwhelming and complicated, so it nice to have some knowledgeable who can walk you through the process. Rhea and her team explained everything to me right from the start, so I knew from the beginning I was in good hands. Everything administratively done on time. The staff was completely on top of all the steps during the entire project. Also, the installers were terrific. Tim and Dylan came out to my house before the project started and we did a walk-around and they explained what I was to expect. We have a landscaped yard that we have worked on for over 25 years, and installers took as much care as they possibly could to preserve and protect our plants and patio, which we really appreciated. Tim and Dylan showed up on time every day and completed the project when they said they would. Tim is a great backhoe operator, and he really did a great job of working around some very tight spaces in my backyard. Lastly, their bid was extremely competitive and was even less than a local contractor that was recommended to me by a neighbor. The Septic Group had to travel over 50 miles each way from Lake Stevens to Normandy Park to install my septic system. I really can't imagine that I would have gotten that good of service from anyone else. Thanks Septic Group!

Evergreen On-site, division of the Septic Group, performed our annual inspection of our system. Technician did a thorough job and gave us an honest opinion on the current status of it. however, we had to get them back 2 times to correct an alarm issue that was found to be caused by a pump filter they forgot to clean during the initial inspection/service. We were happy with their service and the promptness in doing it.

Had an issue with 100 year old septic, and they went above and beyond to take care of me. Absolutely loved the support and brainstorming I got from the back-office and field team.

The Septic Group did a great job for us in repairing and servicing our septic system. Scheduling and billing was easy. The on-site team were pleasant and professional. The crew was on-time for each of the two appointments and were very clear on what was done to the system.

The pump went out while they were pumping out the septic tank. They came back promptly the next day and replaced it.
