First you might ask when should you drain and clean your hot tub? We recommend doing so when...
- You just purchased a home and the hot tub came with it.
- You haven't done so in the past 5-6 months.
- Your spa water is giving off an unpleasant smell.
- You have itchy and irritated skin after getting out of your spa.
If you use your hot tub regularly you should drain and clean every 2-4 months. Your hot tub is basically a bath tub that never gets drained and it's used over and over again. And since it's a smaller body of water its more difficult to keep in balance if you don't make this a part of your regular maintenance routine.
1. Purge Lines
Before you drain your hot tub you should clean your lines with Spa Purge. Do this by filling the tub one inch above normal water height. Remove the cartridges and add one half bottle of Spa Purge per 500 gallons. Run the jet's for about 45 minutes. Turn the jets off (but leave the circulation pump on) and let the spa circulate overnight.
If you don't think your hot tub needs to be purged you may skip on to the next step.
2. Drain & Clean
The day after purging or before draining, run the jets again for five minutes to dislodge and debris in the lines. Then rotate any valves to make sure each jet has ran. Turn off the power to the spa using a circuit breaker or the quick disconnect. If you haven't done so already, remove the cartridges and clean them with Filter Cleaning Spray. You can now place your water pump in the spa and start removing the water. While draining the spa, wipe down the top, water line and any dirty areas with a cleaning agent such as LC3. When the drain is finished, rinse out the spa with a garden hose and vacuum out the remaining water with a shop vac. Wax the shell with Leisure Time Fast Gloss (acrylic smooth shells only). Refill the tub and install dry cartridges (if available, do not install if they are wet).
3. Fresh Fill
You can now add the garden hose to start filling your spa. If you have well water we recommend using a Bobby Sock to help filter out those harsh metals. You can also add Metal Gon to help protect your spa from these metals attaching themselves to any surfaces. Once it's completely filled and has ran for over 12 hours, bring your water sample in to be professionally tested. If you don't have time to do so you can simply add your initial dosages recommended on the back of your regular weekly chemicals.
