If you think the only step behind hot tub drainage involves a simple “pump and dump” of your spa water, you’re already behind on saving both time and money from troubleshooting endless hygiene and water chemistry problems. Once you learn the proper method behind draining and cleaning out your hot tub, you’ll tackle filtration issues early on, and help extend the lifespan of your spa. Fortunately, this guide will list will cover all steps you need to ensure you’ll drain and clean your hot tub the right way.
Know the brand, model and location of the drain of your hot tub.
While this may seem the most obvious, drains are often located in different locations depending on the brand and model of the hot tub. Most models have drains located on the base below the front panel next to the control board, while other higher-level models contain extra features to make draining easier.
Turn off the spa’s circuit breaker.
With the circuit cut off, you can guarantee your hot tub won’t try to heat, filter, and pump during the draining process. Just be sure not to turn your circuit back on until your spa is filled to normal operating levels.
Drain with a submersible pump
Place the pump inside the tub. If your pump’s outflow hose isn’t long enough to reach a drain, attach a garden hose at the end of it. Turn the pump on and allow the spa drain. Once the hot tub is empty, turn off the pump, detach the hose and remove from the hot tub.
Drain with a hose
Locate the hose spigot. Your spa model may have two spigots, a primary and auxiliary spigot. Use the primary spigot to drain a majority of the water outflow, while using the secondary spigot to drain the internal bleedlines. Unwind your garden hose. Be sure to unravel it to a safe distance where water can be drained successfully. When your hose is attached, open the spigot to allow the water to drain. This process is called a gravity drain. Although this method of draining takes longer than with a submersible pump, utilizing your hose can be just as effective.
While you wait for your hot to drain, clean your filter at the same time
It is best to spray down your filters regularly every month with a hose, or keep them soaked in Filter Cleaner, sprayed down and inserted back in your hot tub every 4 months.
Remove any remaining water
Once the spa is mostly empty, use a mop or wet/dry vac to remove any remaining water left at the bottom of the hot tub, as well as the seats and footwell. You’ll want to have your spa as dry as possible to allow the best possible cleaning. Use a soft, dry cloth to ensure all moisture is out of the tub.
Thoroughly vacuum out your equipment compartment
Now is the time to check for any cobwebs, dust or dirt that may linger in this area.
Once the spa is drained, clean the interior
With protective gloves, use a washcloth or rag combined with a Multi-Purpose cleaner to remove any dirt, stains, grease and scale the lines the interior. You will want to apply it all over the tub. Make sure to wipe out the front of jets and any crevices that are hard to reach, where most debris may be located. Let it sit for a few minutes and then scrub it off. Rinse well with water. You can also apply a polish and wax protector on the surface of your tub, to create a shiny coat that will help maintain the integrity of your hot tub’s surface.
Put the drain cap back on
This is a simple but important step to follow!
Refill the hot tub
Once you feel the hot tub shell is clean, insert a hose through the filter as if you were filling the spa for the first time, and begin to refilling your hot tub.
Maintain a consistent drainage schedule
While you may simply prep your hot tub for the winter or flush the system in the summer, it is recommended that you drain and clean your hot tub every 3 - 4 months, to get the most out of your spa usage.
