How to Drain, Clean, and Refill Your Hot Tub Properly

Regular maintenance is key to keeping your hot tub in top condition. Draining, cleaning, and refilling your spa is an essential part of this process to ensure clean water and a safe soaking experience. Here’s a step-by-step guide on how to drain, clean, and refill your hot tub the right way.

Why Regular Draining and Cleaning Is Important

Over time, spa water accumulates dirt, oils, and other contaminants that can make the water cloudy and impact its quality. Draining and cleaning your hot tub every 3–4 months helps prevent issues like scale buildup, unpleasant odors, and ineffective sanitation.

Step 1: Turn Off the Power

Safety first! Before you start, ensure your hot tub is completely turned off and disconnected from its power source. This prevents the risk of damage to your pump or heater while the water is drained.

Step 2: Drain the Water

To drain your hot tub:

• Use the Drain Valve: Locate the drain valve on your spa and attach a garden hose to direct water away from the area.
• Use a Sump Pump (Optional): For faster drainage, consider using a sump pump.
• Dispose of Water Safely: Be mindful of where the water flows to avoid flooding or damaging plants.

Step 3: Clean the Shell

With the water drained, it’s time to clean the spa’s interior:

• Use a Spa Cleaner: Choose a non-abrasive cleaner designed for hot tubs to remove dirt and grime.
• Scrub Gently: Use a soft cloth or sponge to scrub the shell, paying attention to any waterlines or stains.
• Rinse Thoroughly: Rinse off all cleaner residue to prevent foaming when the spa is refilled.

Step 4: Clean or Replace the Filters

Filters play a crucial role in keeping your water clean:

• Rinse the Filters: Remove the filters and rinse them thoroughly with a garden hose.
• Deep Clean: Soak them in a filter cleaner to remove oils and debris.
• Inspect for Damage: Replace filters if they show signs of wear or damage.

Step 5: Refill Your Hot Tub

To refill your spa with fresh water:

• Use a Hose Filter: Attach a hose filter to remove impurities as the spa fills.
• Fill Through the Filter Well: This helps prevent airlocks in the plumbing.
• Stop at the Proper Level: Check your owner’s manual for the correct water level.

Step 6: Reconnect the Power and Balance the Water

Once the spa is refilled:

• Turn On the Power: Restore power to your hot tub and let it run.
• Test and Balance Chemicals: Use test strips to check the water’s pH, alkalinity, and sanitizer levels. Adjust as needed.
