Facts about septic systems
from the rare septic enthusiast who replaced his tank voluntarily, not because the government ordered it.
Solids are supposed to settle in the septic tank, not make it out to the leach field. When too much tank space is taken up by solids it's time to get it pumped, or solids may get out to the field and clog it. Once the field is clogged, pumping the tank isn't going to help. Then you're in for considerable expense, unless you have an alternate leach field to switch to. That'll give the original field a chance to rest, which may restore it to working order.
10 years or so ago, I got concerned about my leach field, because if it failed I would have to hook up to the sewer system. A good septic contractor told me that if I want the field to last, I should get a two-compartment tank with an outlet filter. He suggested a 1500-gallon tank, but I went for 2000-gallon which didn't cost much more. The tank has risers up to the surface so I can easily check it. I check at least once a year. So far there's moderate sludge in the first compartment, and no sludge in the second compartment (judging by poking with a 2x4). As long as it's like that, there's no benefit to getting the tank pumped. When I check the tank I also clean the filter. I always find stuff in it, but it's never been completely full.
