Flushing & Cleaning the Lines
There are many plumbing lines in a spa. No matter how clean you keep the water, chemicals only clean the water, not the plumbing lines. Bacteria and mildew-attracting scum can accumulate in the vast number of spa plumbing lines and fittings. You need to flush and clean them in order to prolong the life of your spa and keep it running smoothly.

We strongly recommend flushing and cleaning the lines every six months to one year, or whenever you notice a skim film developing around the spa fittings. You should do this procedure right before you drain your spa.

Use a spa bath & spa cleaner to dissolve the build up of body oils, dirt, hair, soap, scum, rust, and mineral deposits which are the perfect breeding ground for bacteria and mold.

1. Pour the spa bath & spa cleaner into the spa water.

2. Close all therapy valves.

3. Turn all the pumps and blowers on high for approximately 10 - 15 minutes. The water will become very sudsy. Monitor the water so it does not foam over. If it looks like it will, turn off all pumps and blowers and wait for the foam build-up to subside.

4. Let the water soak in the spa and plumbing lines for three hours with pump and blowers turned off.

5. Open the air controls.

6. Turn pumps and blowers back on for about 10 minutes and monitor the spa. Sudsing may reoccur.

7. Shut down all pumps and blowers, and turn the spa circuit breaker off.

8. Drain the spa.

9. Once you drain and refill the spa, turn on all pumps and blowers for 15 minutes to eliminate any suds still remaining in the lines.

10. Drain the spa a second time.

11. Refill the spa again and treat the water with chemicals as you would for any normal start-up.
