We strongly recommend that you never leave your spa empty for a period of 2 weeks or months. Leaving your spa empty can cause damage to the pumps, heater element and shell. In most cases you are better off turning the spa temperature down to the minimum setting and maintaining your PH & Alkalinity levels to ensure they stay within recommended readings.
If for some reason you need to empty your spa for a period longer than 2 weeks we recommend the following.
Clean the pipes and inner surface using the spa pipe degreaser. Follow the dosing instructions on the label and circulate the pipe cleaner for the prescribed amount of time. This will clean the internal surfaces of the spa plumbing and equipment.
Make certain the power to your spa is disconnected.
Remove the drain cap on your spa and drain the water from your spa following the manufacturers instructions.
Remove your spa filters. We recommend soaking them for 24 hours in a spa filter cleaner. Follow the dosing instruction on the label of the filter cartridge cleaner.
After your filters have soaked for 24 hours, remove them from the solution, rinse them off and set them out to dry.
Once the spa is empty and dry and the filters are dry, put the filters back into the spa to make sure they do not get lost over the winter.
Loosen fittings. Once the spa is empty, open the cabinet door to gain access to your controller and all pumps.
Undo the barrel unions that connect the plumbing to the spa controller, heater and pumps. Undoing these unions will allow any excess water in the pipework of the spa to be drained. Without following this process stagnant water will sit in the pipework and cause damage to the seals in your pumps and your heater element and control sensors.
Purge water from the pipes and shell. Many people will use a wet and dry vac to either suck or blow the remaining water from the pipes. This is more critical if you are in a colder climate. Use a sponge or the wet and dry vac to remove remaining water from the foot well, seats and filter well. Once the spa pipework is empty of water, carefully re-connect and tighten the unions ensuring that the O-ring seal is seated correctly.
Clean your spa shell, we recommend using pipe cleaner on a sponge and white vinegar diluted with water by 50% can remove any white calcium lines. The key is to use very little water in the cleaning process so there is less to remove. Dry the shell with a soft towel. Our recommendation is to leave the cover off for a period of time to allow the shell to dry. (As per warning instructions on the shell, do not expose the acrylic shell to direct sunlight for extended periods of time).
