Septic Tank Pumping

A septic tank system, like any other piece of equipment, lasts longer and will function better with regular maintenance. It is highly recommended that your tank be pumped every 3-5 years to remove accumulated sludge and scum. Otherwise, after time it can cause your drainfield lines to clog causing the drainfield to fail which can lead to costly repairs.
