Owning a hot tub is a great gift to yourself, but you must know how to winterize a hot tub. Maintenance is an issue; using the hot tub in the spring, summer and fall is great, but there is always winter. There are a few things to consider when you winterize a hot tub. Taken step by step, though, it is quite simple.
- Cut the Power. When dealing with electrical items, the first thing you want to do is cut the power. Your life may depend on it. Turn off the power to the heater first, then cut the power at the fuse panel of the home. This might be a good time to check your GFCI by hitting the test switch. This will make sure that your breaker does work.
- Drain the tub. Now that it is safe to start to winterize a hot tub, start by draining it. You can do this by either siphoning the tub with a garden hose, or connect to the drain on the side of those that have them. If you have an electric blower, you can use it by turning power back on to the tub, temporarily, and running the blowers for about one minute to vacate the lines. Clean the remaining water with either a shop vacuum or mop of some kind.
Drain the inside. Once the main tub is drained, take the cover off. Now you can loosen the PVC couplers on the heater housing. Also loosen one on the pumps to allow for the water inside to drain. One tip, now is a good time to take out the filter compartment. Remove the filters and soak them is a filter cleaner. Once they are clean, store them in a dry place till spring. If your tub is equipped with a separate filter canister, be sure it is fully drained as well. Remove any bleed valves and drain the hot tub has. This is to allow for complete drainage of the inner lines of the tub.
- Clean it up. While you have the cover off, now is a good time to clean the system. This will make sure that when you go to fire it up in the spring, it will be ready. Clean the shell of the tub. Then clean the cover. It is a good Idea to put a weather treatment on both sides of the cover. Do not use any silicone based product as it will deteriorate the top faster. Replace the cover, cleaning it both inside and out. If it is a wooden cover, you may want to seal it with a weather treatment. This will help keep the wood from rotting if the winter is damp and cold.
Some people actually keep there tubs full year round; they like the feeling of coming home after working in the snow, then jumping in that warm water. One tip, do not use the air jets to keep the water warm. They are counterproductive. Remember the air around the tub is cold. If you prefer to save on electricity in the winter though, then drain the tub and enjoy your winter.
