It can be hard to know when your septic tank needs to be pumped. To keep your drain field working as long as possible, you should have your tank pumped every three to five years. However, if your drains make a gurgling noise, have a foul odor, or are just draining slowly, your septic tank may need to be pumped sooner. Our professionals at HST LLC have the skills and resources to get your tank working properly and follow the environmental requirements.
