Many hot tub owners don’t realize the importance of a routine spa purge. While maintaining water balance in your hot tub is also very important, don’t neglect to periodically purge, drain, and refill your spa water. This keeps your water looking its best and your spa working optimally.
What is purge?
Even with proper water balance, the water in your hot tub will have some contaminants and build up that cannot be removed by your filter. In order to completely remove those contaminants and build up, you must purge the spa plumbing lines. When you purge your spa, you are removing biofilms and other accumulations. The process involves running a spa purge through the plumbing before draining the water and then refilling with clean water.
Why is it important?
Using a purge product is critical for removing chemical buildups and other gunk that naturally accumulate in your spa over time. While keeping your water balanced goes a long way in keeping your water clean, that maintenance alone will not remove the accumulations of biofilms, scaling, etc.
If you’ve noticed that your water is cloudy, slime is forming, or the water is emitting an odor, it’s a good sign that you need to purge, drain, and refill your hot tub. If you use traditional chemicals, it is recommended that you purge, drain, and refill every three months. With the Waters Choice enzyme systems, you only need to drain once a year.
How to complete each step
Purge: Use Waters Choice Clean & Drain to effectively remove build up from the surface and the plumbing lines of the hot tub. Squeeze entire tube into the filter area with the filter removed. Allow it to circulate through the spa with the jets on high for at least one hour to ensure the biofilm is stripped away from the lines. This is essential because failing to purge the plumbing lines will allow the biofilm buildup to circulate back through your water over and over again. Also remember to clean your filter at this time. You may put the filter in the center of your spa to float around while Clean & Drain is working its magic.
Drain: After the one hour purge process, start to drain the water from your spa by following the directions in your owner’s manual. As the water is draining, hold a hose up to each one of your jets and allow the water from your hose to flush out each jet. Make sure to wipe the foamy gunk off while it is draining. If you wait and it dries, it will be very difficult to get off. When the water has been drained, clean the entire surface of the spa with a soft rag to remove dirt. This includes cleaning spa pillows, the water line, inside and around jets, etc. If you need to, you can use a rag dipped in bleach/water solution.
Refill: After you have thoroughly cleaned your hot tub, refill it with fresh water. You can use our Turbo Ion Exchange Filter to refill your tub and get rid of contaminants in your fill water.
Using Waters Choice enzymes cut down on the need to purge your spa frequently, but it is still necessary to purge once a year.
