Septic Pump Damascus Oregon & Surrounding Areas

Septic pumps, also known as aerators, are vital to providing oxygen to a septic wastewater treatment . Goodman Sanitation in Portland, OR provides different models and sizes that will suit your specific needs.

When replacing a failed septic pump, it is important to have the same size and model designed originally for your septic tank to properly handle the volume of air. Bigger is not necessarily better. A too large air pump could possibly generate too large a volume of air for the diffusers to handle. This will cause backpressure and might cause the air pump to run to hot and thus fail prematurely. A too small aerator will not allow enough air to enter the tank to ensure proper growth of aerobic bacteria. Then inadequately treated sewage could possibly clog your drainfield much sooner than it should otherwise.

It is also important to choose the correct repair diaphragm for your septic air pump. Make sure the diaphragm is one designed to work with the specific air pump to ensure it works correctly. Goodman Sanitation has highly skilled professionals at the ready to install the correct septic pumps and diaphragms for your septic tank wastewater treatment .
