Here at BMS Spas, we love spending time in our spas, even during the cold weather. But we know that might be a bit extreme for everybody. After all, it can get properly cold, even in the UK.
So, if you’re the kind of person who’d rather just close up their hot tub over the winter and not have to battle the snow, read on to find out how to winterise your hot tub.
Do I Need To Winterise My Hot Tub?
The first thing to bear in mind here is that you don’t actually have to winterise your hot tub. You can simply leave it running all winter. So long as the heater is kept on to keep the water warm and flowing through the hot tub, you shouldn’t have any issues. And, with a thermally insulated cover, it’ll take less electricity to keep the hot tub warm and safe all winter long.
However, if you know you’re not going to be using your hot tub – why spend the money to keep it warm, or the time to keep the water balanced? Just a little bit of effort will ensure that your hot tub is properly decommissioned for the winter, and then you know nothing can go wrong.
How Do I Winterise My Hot Tub?
So, if you are going to go ahead and prepare your hot tub for winter by shutting it down, how do you go about it? Here’s our step-by-step guide.
Most of these steps should be familiar to you, as they’re very similar to what you’ll do when you’re cleaning your hot tub and draining it.
1. Prepare the water by letting the chemical levels lower
The first step is to make sure you let the chemical levels in the hot tub drop. This is because you don’t want to release the chemicals into the environment, as they can be toxic.
So, simply leave the water for a few days without adding any of the normal chemicals and cleaners. Test the water and move on to the next step when the chemical levels have dropped to zero.
2. Make sure there’s no electricity running to your tub
This one is an essential safety tip. Make sure that there’s no electricity running to your hot tub. Either turn it off at the fuse if it’s hardwired or unplug it.
3. Drain the hot tub, including the plumbing lines
The next step is to drain the hot tub. You can do this in the normal way that you would normally drain your hot tub, either using a drain cap or a pump, if you have one.
You also want to make sure that you empty the pump or air blower. There should be a drain plug on your pump, so simply remove this to allow the water inside the pump to drain out.
4. Remove the filters and give them a clean
Then, remove the filters. There’s no need to leave them in your hot tub over the winter.
Technically, you don’t need to clean them – but you don’t want to store dirty filters all winter, so take the time now to give them a good once-over.
You could also just replace your filters if they’re too dirty. Then, just use a sponge or towel to remove any left-over water in the filter well.
5. Make sure you blow out the lines thoroughly
This step is one of the most crucial in the entire process, as it’s what protects the internal plumbing of your hot tub. If you do leave a bit of water in the plumbing lines, it can freeze over the winter and expand, which may damage your hot tub.
You’ll want to use a wet/dry vacuum here, on the blow setting. Then simply use the hose to blow the water out of every drain, jet and filter cavity. Make sure you do this carefully and thoroughly, as any water left in any of the plumbing lines can cause a major issue over the winter. Then, simply mop up this water from the bottom of the tub.
6.Clean the hot tub all over
Now you’ve got a hot tub that’s completely dry, it’s a good time to give it a good clean. Remember that you don’t want to rinse everything again, so use a cloth and wipe everything dry once you’re done.
Clean the shell of the hot tub, as well as the cover. Remember to wipe everything dry, and, if possible, let it air dry even further if you’ve got some nice weather!
7. Make sure the cover is tied down securely
So, now you’ve got a nice clean and dry hot tub, the last thing to do is to securely fasten the cover back over the hot tub. Make sure it’s nice and secure, as you don’t want any little animals able to access the shell of your hot tub and nest in there. It might be worth using some additional straps to keep the cover safely tied down.
There you go – just seven simple steps to winterising your hot tub. If you’re not going to use your hot tub over the winter, it’s worth putting that little bit of effort in to keep it in the best condition.
