Keeping a hot tub spa clean is not just about clear water; it is crucial for protecting the equipment, ensuring safe soaking and extending the lifespan of the entire system. Although regular water quality maintenance plays a significant role, a frequently overlooked maintenance task is proper drainage and cleaning of equipment. Understanding how and why hot tub spa drain cleaning is necessary will help you maintain the health and reliability of your system throughout the year.
Over time, pollutants such as human body oils, lotions, cosmetics, sweat and environmental debris will accumulate in water. Even with the adoption of an efficient filtration system and a complete disinfection procedure, these organic substances will gradually form biofilms inside the pipes.
When biofilms accumulate, you may notice that the water quality remains persistently turbid, emits an unpleasant odor, or the concentration of disinfectants is always unstable. Drainage and cleaning, especially when using a dedicated spa tub cleaner, can wash away these hidden contaminants. This helps keep the water clear, improve the efficiency of the equipment, and ensure that your hot tub can be used safely.
For most hot tubs, it is usually recommended to drain and refill the tub every three to four months. However, not all spa tubs require the same frequency of water changes.
If your hot tub spa is used by a large number of people, frequently hosts parties, or is used for spa treatment several times a week, you may need to drain it more frequently. Embedded spa tubs integrated with the swimming pool system usually rely on continuous filtration, so they do not need to be thoroughly drained as frequently as other types of spa tubs. However, it is still beneficial to regularly clean the internal pipes to remove biofilms and hidden contaminants.
Before draining, use a pipe cleaner first. The cleaner will circulate in nozzles and internal pipes, breaking down grease, dirt and biofilms. Just add the product as per the instructions and then run the nozzle for 20 to 30 minutes (or for a longer time as recommended).
Be sure to turn off the circuit breaker of the spa tub before draining. This can prevent the water pump or heater from operating unexpectedly without water, thereby avoiding overheating and expensive equipment damage.
Most hot tubs are equipped with built-in drain valves, but for faster drainage, many users prefer to use pumps. No matter which method you choose, place the hose away from plants or lawns, as chemically treated water may cause damage.
After emptying the hot tub, wipe the entire interior with a non-abrasive, spa cleaner or a simple mixture of water and vinegar. Special attention should be paid to the water line, as grease and dirt tend to accumulate there. Remove any substances remaining after emptying.
Rinse the nozzle, seat and accessories with clean water to wash away any remaining debris or detergent. Make sure all the excess water is completely drained to avoid leaving any residue before refilling.
Remove the spa filter and clean it with a hose or filter cleaner. If the filter has been in use for more than 1-2 years or appears worn out, please replace it. Clean filters can enhance water transparency, reduce the load on water pumps, and help maintain the chemical balance of water quality.
Fill the hot tub with clear water, preferably through a filter chamber, to reduce air resistance. After filling, restore the power and let the water circulate.
Test and adjust the pH value, alkalinity and the content of disinfectant. Once the chemicals are balanced, your hot tub spa can once again offer you a clean and comfortable soaking experience.
A proper drain and clean is one of the most important aspects of hot tub spa maintenance. It can ensure that your system runs smoothly, help avoid expensive maintenance costs, and make sure you feel fresh and comfortable every time you soak.
