"Excellent! Marty and his partner definitely know septic systems and how to evaluate their functioning level. We were very pleased and impressed with their knowledge, work ethic and the time they spent carefully checking every part of our system and explaining what they found to us. I will definitely use them again and tell neighbors as well. Several folks in my neighborhood tried going with the lowest bids on septic issues and all three had major repercussions! It pays to hire high quality people."

"When the crew understood how concerned I was about the entire condition of the septic system, they took the time to explain to me every detail of what needed to be done, what they were doing at the time, and how the system would work with the pump when the project was completed. Every crew member was professional, courteous and skilled at what looked to me to be a complicated (and icky) job. I received multiple phone calls to ensure I knew when they were coming and what was to be done. There were no surprises for me, and I can flush with confidence thanks to them knowing that my brand new tank and pump are installed 100% correctly. (It easily passed county inspection.) This was an excellent experience, and I would hire them again in a heartbeat !"

"Our existing septic tank was only a few years old, but the associated drainfield was failing and required replacement. Due to a small lot, our options were limited; but rather than a huge and unsightly bottomless sand filter, we opted for a less obtrusive (but expensive) treatment unit and pumps along with the needed replaced drainfield. Cory was very helpful in explaining complex options and costs."

"I had a clogged drain line near the street that a rooter guy couldn't break through. I thought I was looking at having to replace the entire line. At the risk of throwing good money after bad, I called Grumpy's. I got great advice over the phone including a number to call if I decided to have the line dug up. The rate I was quoted was reasonable. Grumpy came out and cleared the line in less than half an hour. In addition, he put a scope down the line, found the exact location where roots were getting through, and marked the spot with paint at no extra charge. He wrote down the coupling and pipe I would need to make the repair. When I dug, the break was right where he indicated. Grumpy was a real pro. He saved me a bunch of time and money."

"Great. He found the metal blocking the disposal and saved me having to install new one. Tightened my faucet in about half a minute. Replaced line and shut off valve to my dishwasher, increasing my water pressure. Showed me how to take toilet fill valve apart to clean out rust so I did not have to call them again."

FAQs for septic system installation and replacement projects in Mulino, OR

The smallest standard septic system uses a 500-gallon tank, which costs between $875 and $1,150 installed. This size works well for single-occupant dwellings with minimal wastewater production. However, many local regulations specify minimum tank sizes, so check with your building department before committing to this compact option. Some jurisdictions require at least 750 gallons regardless of home size to ensure adequate waste processing capacity.

The installation timeline varies based on site conditions, permit processing, and contractor schedules. The process includes obtaining permits, conducting soil tests, excavation, tank placement, leach field construction, and final connections. Weather conditions, soil challenges, and inspection scheduling can all affect the overall timeline. It's wise to begin planning well in advance of when you need the system operational.

The most economical approach is to install a conventional anaerobic system with a plastic tank. To minimize costs while maintaining legality, obtain multiple quotes from licensed installers, consider scheduling during their slower seasons, and handle basic site preparation yourself. Never skip permits or required testing to save money—illegal installations can result in significant fines and mandatory removal, ultimately costing far more than doing it right initially.

Regular pumping helps prevent system failures and extends operational life. Most small systems require pumping every three to five years, though frequency depends on household size and usage patterns. Pumping services cost between $290 and $530, making this maintenance expense relatively minor compared to potential repair costs ranging from $500 to $2,600 for neglected systems. Establishing a regular maintenance schedule based on your installer's recommendations helps avoid costly emergency services.
