I must've probably mentioned it before, but over the summer I installed a "Sense" energy monitor in my house. It's just two clamps (one on each hot leg entering the house) and a wifi-enabled module. It senses current (get it?) and reports not only your instantaneous net usage, but also uses machine learning to recognize individual devices in the house to tell you (educated guess, really) what they are and then you can track devices individually. It does this based on other data collected in their cloud and devices positively identified by other users (so they more people who use it the better it will get). So last night I see a device identified as a "pump" drawing like 1500 watts and not shutting down. Couldn't for the life of me figure out what it was, as I hadn't see that device using much juice at all before.
So this morning I wake up to a septic tank alarm . Looks like my septic pump bit the dust last night. Gonna be like a $1500 hit. But pretty neat that I had this little advance warning.
well, it actually wasn't the pump. Possibly much worse .
Water was draining back down from the drain field into the outlet tank, causing the pump to run continuously. Until it shut down, possibly due to the float switch (again) being bad- I don't know if excessive runtimes can cause a float switch to fry, but who knows.
Signs of the drain field going bad. Which would mean excavating a whole new drain field somewhere else. BUT I've done some research and (everything here based on reading the web) this is usually caused by a "bio mat", which is a sediment field of biomass which forms at the bottom of the drain field and prevents the water from draining into the ground. AND- not surprisingly!- several companies have a solution! It's "septic aeration"; i.. turning the microbe process in the tank from anaerobic to aerobic, which results in a much cleaner effluent. AND the anaerobic microbes in the cleaner effluent water will work to eat away and eventually break down the biomat, bringing the system back to normal efficacy.
For the short-term they put a check valve in the output tank, so water can't flow back down into the pit to cause the pump to chase its tail again. But who knows how long before the ground becomes totally saturated and I start seeing puddles on the lawn (a/s/i "Meet the Parents"). Gonna wait for my neighbor (who is a commercial sewage plant designer/installer, who actually installed my system for the prior owners) to return from vacation around 1/6 before I take any action, though. Should have a pretty long runway before we reach critical mass (knock on wood).
Anybody have any experience with "septic system aerators"?
seems like caustic soda is, yes, a viable solution that also has its downsides
looks like yep, we're past the rid-x stage. that's apparently meant to keep the enzymes in the tank in balance to keep eating @#$%. It is however something that probably should be used if you do use caustic soda, which destroys the tank enzymes on its way to the drain field.
