There's been a couple of septic tank threads lately so thought I would discuss mine . It's been 10 years ( when we bought the house ) since we had the tank pumped . It's a 1000 gallon concrete tank . It's only my wife and I living here but we do get family visiting . This week our grandson graduates high school . We will have 10 people in the house for 3-5 days .
It has rained a LOT here so I figured get the tank pumped and give the leach field a break . So made an appointment and the guy shows up today . I had already removed all the screws from the riser cap . I greet the poop 💩 technician and take him to the tank . He removes the lid , looks down into the tank and looks at me . The good ole boy says I can pump your tank and take your money ( $450.00 ) or you can leave it as is because this is the best tank I have seen in a loooong time .
He gave me quite the education , pointing out that whatever we are doing ( nothing ) it's working . No solids visible just water/other . He pointed out the massive amount of bacteria and flies which means the system is working darn near perfect . He said whatever you're eating it's working at the back end

. He walked the leach field and said there is no visible issues at all . Whew ! I gave him 100 bucks for his time and we are literally good to go
