Appliances that use excessive amounts of water can put a significant amount of strain on your septic system. Even the most efficient septic system can buckle under the pressure of processing the water load from a hot tub, but that doesn’t mean you have to simply drain and store away your sauna. There are a number of things to do to ensure that both your hot tub and your septic system continue to run effectively.
Don’t Connect Your Hot Tub Directly to Your Septic System
Draining a hot tub means dumping a huge amount of water in a very short amount of time, and septic systems aren’t designed to handle that amount of strain. Forcing that much liquid into your septic tank all at once can cause it to overflow, draining potentially forcing solid waste into the outlet drain and contaminating your filtered water system. Unfortunately, keeping a hot tub clean and sanitary means draining it at least once every three months. The easiest short-term solution is to simply drain your hot tub manually. Invest in a sump pump with a hose or a wet vacuum to make the process easier and avoid causing unnecessary damage to your septic tank. This is also a great time to test the status of internal hot tub parts such as the float switch.back to menu ↑
Consider Creating a Greywater Filtration System
“Greywater” is a common and catch-all term for water that’s not clean but not overly contaminated with waste. This includes the water you use in the shower, washing machine, and hot tub. A greywater system serves essentially as a second channel of water drainage for your home, diverting this gently used water away from your septic system to avoid overcharge. Fundamentally, a greywater system works in much the same way a septic tank does, but since the water requires a much less thorough decontamination process, it tends to draw from a much simpler design.
Many greywater filtration systems resemble traditional recycling units, and it’s a fitting design. The water that’s filtered through a greywater system is safe to use to irrigate your lawn. It’s also incredibly cheap to maintain as an accessory to your existing septic system. While it’s less complicated design means that it won’t serve as an alternative to a proper septic tank, it can lessen the burden of draining your hot tub so that your septic system can run efficiently.back to menu ↑
Place Your Hot Tub Away from Your Drain Field
There’s a reason why septic tanks are typically used in rural areas with larger plots of land. The drain field that surrounds the tank is a necessity for proper usage, as the soil in the land soaks up the processed liquid from the tank and helps the tank stay balanced internally. But this soil isn’t intended to stay wet. To prevent erosion, the drain ditch needs to have access to direct sunlight so the water can evaporate. You should always place your hot tub a decent distance away from the field so it doesn’t block the sunlight or cause chemically treated water to leak into the area and throw off the chemical balance of the soil, especially if you decide to drain your hot tub using a sump pump.
