I recently bought my first home that has septic, after 26 years of living with sewers. I've heard that putting lots of water down the septic all at one time is bad for the system, but I'm confused as to why. As I understand it, the septic tank pumps liquids and other broken down material into the leach field, so the water should go right through into the field.
Due to a chronic pain condition as a result of a car accident, I routinely take 2 hour hot showers to help be able to use my neck for an entire work day. With a standard shower head, this means I'm running about 250 gallons of water through the septic system. (And a low-flow showerhead isn't going to get me the pressure I need to help with my neck.) From an environmental standpoint, I'm not too concerned -- after all, I'm basically pumping the water out of my well and putting it back into the ground 100 ft away in the backyard, so the ecological impact shouldn't be too bad -- but I'm worried I'm somehow damaging my system.
Is this going to hurt the septic system? If so, is there something I can do (perhaps by modifying my plumbing and doing something else with shower waste water) to avoid damage?
