Update: Ended up paying Drummac $380 for an evaluation during a septic overflow. The technician and…read moresupervisor both stated our leach field was completely dead and needed to be fully replaced, leaving us stranded. We brought in a second opinion. It turned out the leach field was perfectly fine, the 1/4 HP pump had simply failed. We replaced it with a 1/2 HP pump, and the system drained immediately. Drummac completely misdiagnosed a simple pump issue as a multi-thousand-dollar failure. Buyer beware.

Incomplete service and a lazy, flawed evaluation.
I am incredibly disappointed with the lack of thoroughness and technical competence from this company. I had to do all the heavy detective work and troubleshooting myself because their teams failed to properly diagnose a potential structural issue.
The Major Issues:
1. Incomplete Pumping: The original pumping technician only emptied the main sewage tank. They completely ignored the separate 1,000-gallon pump chamber, leaving it overflowing, above the alarm sensor levels, and actively causing an emergency alert.
2. Lazy Diagnostics: The evaluation technician who came out next refused to wait for the pump chamber to be properly emptied. They attempted to diagnose a complex hydraulic system while standing over a dark, flooded pit.
3. Flawed Logic: The evaluator simply disconnected the pipe union, watched water squirt out for one second, and claimed everything was "fine." All this proved was that the pump motor spun.
4. Ignored Critical Failures: Their rushed test completely ignored a potential failed internal check valve, heavy outside groundwater infiltration possibly leaking through the concrete seals, and the fact that the waterlogged hillside was actively looping water backward into the system.
5. Incorrect Explanations: The technician claimed the high overflow pipe from the empty sewage tank was dripping water into the pump chamber. It is physically impossible for water to climb up four vertical feet from the floor of a completely empty tank to drip into the next chamber. The sound we heard was likely actually groundwater leaking in from the saturated yard. This was a lazy guess by a technician who failed to do their job properly.
We paid over $900 for what we expected to be a proper, professional service. Instead, we were left with an active plumbing emergency, an un-pumped tank, and a completely useless, lazy diagnostic guess that could have cost us thousands more in unneeded repairs.
If you want a company that actually understands plumbing physics, data, and complete system diagnostics, look elsewhere.
