Keeping your cold plunge clean ensures the water stays fresh, the chiller runs smoothly, your routine stays intact and your investment lasts longer. Below is a step-by-step guide to clean your cold plunge and get the most life out of the water.
1. Drain The Plunge
If not already in a location where you can easily drain your plunge using the bottom outlet hole, you can use the connected 5ft hose to direct the water flow by detaching it from the chiller side and running it to a floor drain or directly outside.
If the hose is not long enough, a submersible sump pump can be used by attaching a garden hose to the sump pump. A sump pump is also useful to vacuum out stubborn, small debris that maybe leftover in the last couple inches of water on the floor. If interested, you can purchase one here.
2. Clean The Plunge
After draining the plunge, determine if it needs to be fully detailed. In most cases, you can simply spray the inside with a hose nozzle on jet mode and remove any residual debris as it flushes out of the bottom outlet hole. If a more proper cleaning is needed, follow the steps below:
- Spray the inside and outside with water, use dish soap and scrub gently with a sponge. Rinse thoroughly and ensure no soap suds remain. For stubborn scuff marks, use a magic eraser for a cleaner finish.
- Dry completely before placing the plunge back in position.
- Reconnect all hoses and open the shut-off valves so water can flow freely back through the system.
3. Replace The Filter
Before refilling your plunge, this would be a good time to replace the filter:
-
Unscrew the clear filter housing inside the side compartment of your chiller by turning clockwise.
-
Take a clean filter and submerge it in water for 5-10 minutes. This will prevent it from bobbing in the filter housing.
-
Fill the clear housing completely with water to the top, insert wet filter and seat the filter with the bottom knub of the clear container so the opening sits flush with the bottom of the clear housing.
-
Line the filter back into place under the white lid and turn counterclockwise to screw in place.
- For those with an additional 40-Micron Filter attached to the bottom of their cold plunge, unscrew the clear housing by turning counterclockwise and clean any debris off the mesh filter by running under hot water and using a soft brush. Fill this clear housing with water as well before reinstalling it.
***The clear filter housings must be full of water to prevent air lock - air trapped inside the lines which prevents water flow through your chiller. For a video on how to replace the filter, scroll to the bottom of this page.
4. Refill The Plunge
Fill the plunge with water until the water level is at least 1ft over the bottom hole of the plunge. For best water quality, connect an inline hose filter to your fill up hose to remove contaminants from your local city water, in line hose filters can be purchased here.
-
Ensure the shut off valves are open so water can flow freely from your plunge into the chiller and back into the plunge.
-
Ensure both clear filter housings are full of water.
-
Turn the chiller ON to test for airlock:
-
If water flows out of the top hole of the plunge, continue filling your plunge with water to your preferred level.
-
If no water is flowing, pause filling. With the chiller turned ON, slightly unscrew the large filter housing in the side of your chiller to allow trapped air to purge. Water should start filling the remainder of your filter. Once filter is full of water, retighten the clear housing, turn chiller OFF then back ON to reboot the system.
-
If water is still not flowing, grab a hose and set the nozzle on jet mode. With chiller turned OFF, get into the plunge and point the water directly at the bottom hole. Force water through that hole for 2 minutes, you should see water coming out of the top hole of your plunge (if not, you may have a closed shut-off valve) and the trapped air will release with this process. After 2 minutes, turn chiller on and water flow should resume.
-
If water is still not flowing, and you can hear the pump priming (repeated humming noise), repeat the steps above to release air lock. If you do not hear the pump priming with the chiller turned ON, you may have an issue with the pump.
-
- Once water flow is established through the top hole of your plunge, fill water to your preferred level for cold plunging.
5. Add Sirona™
For crystal clear water, we recommend the Sirona™ line of non-chlorine, non-bromine products. They pair incredibly well with UV-C and are perfectly safe for use with the components inside the chiller.
-
For water filled to the top hole of your cold plunge, syringe 20mL of Sirona Sanitizer and 60mL of the Sirona Oxidizer directly into the water.
-
Allow water to circulate for 24 hours. You will notice cloudy water until circulation is complete.
6. Go Months Without A Water Change
For clean water start up, follow the maintenance routine below and go months without having to replace your water.
✓ The cleaner the body when entering the plunge, the less foreign debris you introduce into the water. It's always a good idea to hose off prior to entering the plunge.
✓ Always keep your chiller turned ON so water flow is constant. Your Pro Chiller is rated for 396 GPH which means it is cycling and cleaning the water in your cold plunge 4x per hour. It is imperative to keep the water flow continuous to prevent stagnant water flow which leads to bacteria growth.
✓ When filling your plunge with clean water, we recommend Sirona's line of products (Sirona Sanitizer & Oxidizer). Re-apply both Sirona bottles every 4 weeks to get the most time out of your water.
✓ Check the filters and replace or clean based on discoloration, visible debris or low water flow into your plunge. Replacing the filter every 4 weeks can keep your chiller operating more efficiently and your water cleaner for longer. When using the shut-off valves, filter changes can be completed in less than 60 seconds.
✓ Ensure the green light is on for UV sanitation. When the light goes off, you will need to replace the UV bulb which can be purchased here.
