The Problem With How Most People Drain Their Hot Tub

Ask most hot tub owners how they drain their spa and you'll hear one of three answers: a submersible electric pump, a garden hose siphon, or — most painfully — getting in and bailing out the last few inches by hand.

Each of these has a serious flaw:

• Submersible electric pumps leave 2–3" of water behind (requiring manual bailing), can burn out if run dry, have intake screens that clog with debris, and mix electricity with water — a safety concern
• Garden hose siphons lose their prime, can't lift water uphill, and drain at a fraction of the speed of a true pump
• Manual bailing is exactly as miserable as it sounds

There's a better way. And it runs entirely on your garden hose.

What Is Pump Marvel?

Pump Marvel is a true venturi-powered vacuum pump that uses the pressure of your garden hose water to drain any vessel — hot tubs, pools, basements, boats, pool covers, and more — with no electricity, no moving parts, and no priming required.

Here's the physics: pressurized water flowing through the pump creates a vacuum (the venturi effect) that draws surrounding water in through the intake. The result: every gallon of hose water that enters Pump Marvel draws up to 3 additional gallons from the vessel being drained and ejects 4 gallons total out of the discharge hose. That's 13 times faster than siphoning — and it drains all the way down to 1/8" depth.

Made in Canada from high-strength PVC, Pump Marvel has no motor to burn out, no seals to corrode, and no moving parts to wear out. It will last indefinitely.

How Pump Marvel Compares to a Submersible Electric Pump

Drain Depth

This is the biggest practical difference. A standard submersible pump stops working when the water level drops below its intake — typically leaving 2–3" of water in your hot tub. That means getting in the tub and bailing by hand, or using a wet vac to finish the job.

Pump Marvel drains to 1/8". Positioned flat on the bottom of your spa, it keeps drawing water until there's virtually nothing left. No bailing. No wet vac. No getting in the tub.

Electricity & Safety

Electric submersible pumps require a power source near water — an inherent safety risk. Pump Marvel requires no electricity at all. It's powered entirely by your garden hose, making it the safer choice for draining pool covers, boats, and any situation where mixing electricity and water is a concern.

It also works during power outages — critical for basement flooding situations where your sump pump has failed.

Burnout & Reliability

Electric pumps burn out when run dry — a common failure mode when draining a spa or pool to the last few inches. Pump Marvel has no motor. It simply stops when there's nothing left to pump, then starts again when water returns. It cannot burn out.

Debris Handling

Submersible pump intake screens clog rapidly with leaves, debris, and sediment — causing the pump to stop working and potentially burn out. Pump Marvel, positioned flat on the bottom, handles debris without clogging as long as it's properly positioned. A standard pool pole attaches to the top slot for easy repositioning without getting in the water.

Confined Spaces

A 1" PVC pipe up to 4' long fits into the bottom of Pump Marvel, allowing it to reach into sump holes, washing machines, aquariums, and other confined spaces that a submersible pump can't access.

How to Use Pump Marvel

1. Connect your garden hose to the Pump Marvel inlet
2. Position Pump Marvel flat on the bottom of the vessel you're draining
3. Direct the discharge hose to your drain or desired discharge point (Pump Marvel can lift water up to 20' high)
4. Turn on the garden hose — draining begins immediately, no priming required
5. Leave it running until the vessel is drained to 1/8"

That's it. No setup. No priming. No electricity. Just connect and pump.
