If you don’t have plans to use your spa during the winter months, you should drain it completely well before the temperatures get low enough to produce a hard freeze.
Hot tubs that are heavily used by bathers should be drained every 3 – 4 months. When it’s time to drain, either drain to a sanitary sewer or use the water for lawn irrigation. Make sure no chemicals have been added for at least 48 hours before draining.
Water in spas filled with sprayed foam insulation will still freeze if not heated. Finding and fixing leaks in that foam is a nightmare! These recommendations could potentially save you a lot of money!
These basic steps will ensure safe, effective shutdown of your spa for the winter months or any other extended period with out use. Factors such as spa installation, location, type will affect the steps and procedures.
Use these recommendations as a guide.
- Disconnect the spa from the power supply.
- Open the drain valve (if installed) or pump out all water.
- Remove the filter cartridge(s). Clean & store in a dry place. (FILTER FLOSSER)
- If possible attach a wet/dry (shop) vacuum (capable of blowing air as well as vacuuming) to the hole in the bottom of the filter housing.
- Using the blower function, blow out any excess water through the plumbing system - allow a good 5 minutes of blowing time.
- Use the shop vac to remove any water blown through the jets into the tub or towel dry any remaining water from the spa, until it is completely dry.
- Leave drain & gate valves open, if you have rodent issues we recommend MOUSE AWAY.
- Close the spa cover and fasten with tie down safety locks.
This is not a job you want to do in freezing conditions, give yourself enough time. Make every effort to ensure ALL of the water is removed – including remnants in the pump lines and jets.
These are common sense steps always be safe around water and electricity.
