# Hot Tub Draining Guide Before Your Move
A hot tub full of water weighs anywhere from 3,000 to 6,000 pounds. Even a partially drained tub carries enough water weight to make transport unsafe and damage the shell during lifting. Getting every drop out before your move is one of the most important prep steps you can take, and in Miami's heat, the draining process comes with its own set of considerations.
When to Start Draining
Plan to drain your tub at least 24 hours before your Hot Tub Moving crew arrives. This gives you time to drain, vacuum out residual water, and let the shell dry. In South Florida's humidity, drying takes longer than you'd expect, so the extra time helps.
If your move is scheduled for a morning, drain the tub two days ahead and leave the cover off during daylight hours to let the sun bake out the moisture. Just keep an eye on the weather forecast. An afternoon thunderstorm (common from June through October in Miami) can refill an uncovered tub quickly.
Choosing Your Draining Method
Gravity Drain
Every hot tub has a built-in drain valve near the bottom of the cabinet. Attach a garden hose, route it to a lower elevation, and open the valve. This is the simplest method but also the slowest. Expect 1 to 2 hours for a standard 400-gallon tub. The flow rate depends on your hose length and the elevation difference.
Submersible Pump
A small utility pump (1/4 to 1/2 HP) dropped into the tub will drain it in 15 to 30 minutes. You can pick one up at any Home Depot or Lowe's in the Miami area for around $50 to $80. This is the method we recommend for most homeowners because it's fast and reliable.
Siphon Method
If you don't have a pump and want faster drainage than gravity alone, you can start a siphon through a garden hose. Fill the hose with water, cap both ends, place one end in the tub and the other at a lower point, then release. The siphon will pull water continuously until the tub is empty or the siphon breaks.
Where to Send the Water
This matters in Miami. Hot tub water contains chlorine, bromine, and other chemicals that can harm plants, pets, and local waterways. Here's what to do:
- 1Landscaped areas: Small volumes of well-diluted spa water are generally okay for established landscaping. Avoid dumping near vegetable gardens or sensitive plants.
- 2Sanitary sewer cleanout: If you have access to a sewer cleanout on your property, this is the best option. The water goes to the treatment plant instead of into the storm system.
- 3Storm drains: Do not drain directly into street gutters or storm drains. Miami-Dade County stormwater regulations prohibit this, and the fines are not trivial.
- 4Neighbor's yard: Obviously not. But we've seen it attempted.
If your water has been sitting untreated for a few days and the chemical levels have dropped naturally, it's safer for landscaping.
Getting the Last of the Water Out
The drain valve and pump will get 95% of the water. The remaining 5% hides in the footwell, jet lines, pump housing, and heater assembly. Here's how to get it:
Wet/dry vacuum: Run the hose into the footwell and every low spot in the shell. This pulls out the pooled water that gravity and pumps leave behind.
Blow out the jets: Use a shop vac set to blow mode or a low-pressure air compressor. Insert the nozzle into each jet opening and blow air through the lines. Open all jet valves and air controls during this step. Water will spray out of adjacent jets as the air pushes through the manifold.
Tilt the tub: If your crew can safely tip the tub to one side, gravity will pull water from the plumbing and pump housing to the lowest point where you can vacuum it out.
Drying the Shell
After removing all the water, wipe down the interior with towels and let it air dry. In Miami, even a "dry" day has 60-70% humidity, so consider running a fan inside the tub or leaving it uncovered in direct sunlight for a few hours. A dry shell is lighter, resists mold, and is less likely to develop that musty smell during transport.
