  • Septic Tank Maintenance and Care: The septic tank is the central part of most septic systems. In doing complete septic tank maintenance it is also important to include the other two basic components, the drain field and the soil. The tank maintenance alone can be complex since many things are to be considered. These tanks are sealed units built to contain wastewater for a period of time. Over time, solids collect at the bottom and require routine pumping to avoid overfilling. Scum floats on the surface of tank water. These are mainly made from the collected fats, oils and greases. During septic tank maintenance these are removed from the tank. Liquid wastes on the other hand flows out to the drain field through an exit hole found on the upper part of the tank. The amount of actual waste being placed in the system mainly sets the stage. Different waste types require different maintenance approaches. Most septic waste falls into liquid, solid, and non-organic categories. Reach out now for quality septic tank maintenance services in Seattle, Washington.
  • Septic System Pumping: While relatively harmless, water is the main concern for liquids. An overload of water can disrupt the normal operation of your septic system, like dealing with drain field over soaking and drain back flowing. The use of chemicals should be controlled due to their impact on the tanks biological activity. Disinfectants as much as possible are to be used for a minimal amount to protect the helpful bacteria that break down waste inside the tank. Solid materials flushed down the drains significantly raise the accumulation of solid wastes in the bottom of the tank. Non-biodegradable items add to the total mass inside the tank. Regular pumping helps keep the tank from reaching capacity. Call us now!

How Does A Septic Tank System Work?

A properly designed septic program (sewage treatment system) removes all waste from a building, divides solid materials from liquid effluent in containment vessels, and directs partially treated effluent to the soil through a drain field. The primary component of any septic system is the septic tank. This underground sealed container gathers wastewater from the property. It isolates solids, begins the breakdown of organic waste, and retains sludge and scum. The result is relatively clear effluent. When functioning correctly, the tank divides solids and liquids. Dense waste materials sink and form a sludge layer. Lighter materials such as fats, oils, and grease float to the top. The partially treated liquid between these layers flows out to the drain field. The following phase is the effluent distribution system. This system moves wastewater from the septic tank to the absorption area. In gravity-fed systems, liquid flows directly through an outlet pipe into the distribution area. A distribution box evenly disperses effluent across the field. Some systems rely on pumps to distribute effluent evenly using pressurized lines. The drain field performs the final stage of wastewater treatment. This portion of the system uses soil and trenches to filter and return water to the water table. Drain field systems may include cesspools, seepage pits, trench systems, subsurface gravel filters, or raised mound systems. Less conventional systems include drip distribution, spray irrigation, or flow release techniques.

How the ST Pro Plumbing Works on Your Tank

The ST Pro Plumbing has experience going back several years, in septic cleaning and septic system maintenance. Our teams knowledge of septic systems is supported by years of hands-on work. Its important for homeowners to be aware of how their septic tank works, even with professional maintenance. Though every septic system is slightly different, each septic tank works in the same manner. Wastewater from your house is carried into the septic tank by gravity. This wastewater is held for one or two days in the tank. The tanks anaerobic bacteria decompose the wastewater over this time. The bacteria help segregate solids, oils, greases, and other floating materials. While bacteria inside your septic tank will do a fine job of breaking down your home’s wastewater, our professionals know it can’t dissolve everything. Tanks have three layers: floating scum, middle grey water, and bottom sludge. Our experts manage the equilibrium of the three layers to keep your system functioning correctly. After remaining in the septic tank for one or two days, the “grey” wastewater inside the tank flows into the drain field. The drain field is a series of perforated pipes inside a trench filled with sand, gravel, tire chips, or other loose yet dense material. We monitor your drain field closely because its condition directly affects system performance. As the wastewater flows out of the holes along the pipes, it enters the soil, which acts as a natural filter for any remaining waste products in the water. Microbes in the soil, along with oxygen, break down harmful elements in the water. A properly functioning drain field allows a septic tank to replenish the surrounding area’s ground water table with clean, potable water. We inspect and maintain drain fields to guarantee proper operation. Household wastewater carries a mix of debris from toilets, showers, sinks, and washing machines. Existing bacteria break down the majority of these materials. Our experts are available to handle any clogs or system backups.

For the Proper Treatment of Your Septic System call ST Pro Plumbing

Properly maintained systems by our experts can tolerate common chemicals including bleach, laundry detergent, and drain cleaners, but you should try not to flush or rinse toxic chemicals into the septic tank. Toxic substances can include paint thinners, solvents, and pesticide products. Grease and cooking fats should not be poured down any sink or drain. Instead, they should be stored in a separate container till they congeal, and then disposed of as a solid.
