A septic system is fairly simple, therefore, septic system maintenance is fairly simple as well. The waste water pipes in your home all connected to a septic tank. The tank collects waste water from your home. The waste separates into a top layer of oil and fat, a middle layer of gray water, and a bottom layer of solid waste. When the solid waste builds up too much, you need to have your septic tank pumped. That’s the most visible element of maintaining your septic system, However, there are some routine habits you should get into.
