Is there a system that prevents bio-mass from happening. I’ve been told that my leaching field is likely saturated with a biomass that prevents the system to properly leaching the effluent from the D box. Last June I had it pumped and checked because it was backing up to the house. When they opened the tank covered the tank was to the top of the lid. The house pipe, I was told, should never contain waste as the outlet pipe from the tank is lower than the inlet pipe. I had the D box dug up (10’ deep) and they jetted and vacc’d the drain field the best they could and put 5 gallon bucket of chemical in the D box and pumped the tank dry to let the chemical do its thing. They said no garantees on this style repair. They wanted to dig up and replace the leech field but said the code has changed from 1000gallon tank to a 1500 gallon tank 3 years after the house was built. They said any change in the system must be upgraded to the new code which means an entirely new system and field... Really??? My house to tank pipe is about 1/2 full if the wife does two laundry loads. It may completly fill the house to tank pipe, and start going up past the gauge I installed, ...know this because I drilled and tapped a 1/4” vinyl tube with a trap on the cleanout plug in the house. My tank is just a single box, the tank outlet trap is intact, and soild concrete moulded inas part of the tank. Its just been me and the wife and the kids may come home for a month or two, we pump out every 2 to three years, easy on 5he bleach, no scraps in the sinc and no grease. I now hear of people using an air pump to get the effluent almost clear as drinking water before leaving the tank and it is completely aerobic. Would this eliminate the biomass situation. To try keep my tank as clean as possible, I even installed a filter on the discharge of the washing machine to catch non-bio lint or hair. The system was installed in 1993. Please address the several questions I have if you could. Ive heard of fracking the leaching field with air , but I also heard its illegal in some states.

I am trying to get my basement re-engineered to prevent flooding, and I am looking for a few plumbing items that I am having trouble finding on the internet. I need a very small sump pump system, maybe about the size of a soup bowl or such, that I could sink into the concrete and pump out water that collects in a low part of the basement. It doesn't need to pump much water,... only maybe a few gallons per hour max when it rains a lot. This pump needs to be turned on automatically by either a small float system or some kind of sensor that would trigger a relay switch to turn the pump on when it gets wet. I also need a pumping apparatus that works by water pressure when the power goes out. I think they are called venturi pumps. Maybe also a plain old hand cranked pump that would pump water outside if the power went out.
