Why Spa Safety Bypasses Matter (And Why We Won’t Sell a Spa Without Them)

Spa World has been around for over 40 years, and in that time, we’ve learned a lot about spas, what makes them great, what keeps them running, and most importantly, what makes them safe.

We’re proud to be one of the largest spa retailers in the world, and there's one thing we never compromise on: safety. That’s why every spa we sell has a safety bypass system built into the footwell. Not all spa brands offer this, but we believe it’s a non-negotiable feature. Here’s why.

In this guide, we’ll explain:

• What a bypass filtration system is and how it works
• Why Spa World brands like Vortex^®, Fisher^®, and Jacuzzi^® Spas choose this system over the no-bypass method used by some other brands (e.g., HotSpring^®)
• The pros and cons of each system
• Why footwell filtration matters and how Spa World brands design around it

How it works:

• Water normally flows through the main filter.
• If that filter gets blocked (by leaves, debris or a person), the bypass suction points take over, reducing the suction at the filter pipe.
• This helps prevent strong suction from building up and protects people from injury.

Bypass systems are an important safety feature, especially for families with children.

If a filter gets clogged, a spa without a bypass system can develop dangerously strong suction, especially near the filter inlet. This can pose a serious risk, particularly for children.

With a bypass system:

• Suction is safely rerouted to the footwell suction from the filters
• Entrapment risks are significantly reduced
• Approved safety covers help prevent hair or body entrapment in the footwell suction

In a non-bypass system, blocked filters can lead to overheating, breakdowns, and costly repairs because the pump will be running partially or fully empty

By making sure there is a constant water flow:

• The pump works more efficiently
• You extend the lifespan of your spa’s core components
• You save money on ongoing maintenance and repairs

What Is a ‘No-Bypass’ Filtration System?

In a no-bypass or 100% filtered system, all water flows through the filter, no exceptions. Some brands promote this as a way to ensure that all circulating water is filtered before entering the pump or jets.

How it works:

• Every drop of water is pulled through the filter.
• If the filter becomes clogged, suction increases at the filter inlet.
• Without a bypass, this can create strong suction, posing a risk, particularly if the filter is removed or compromised.

Why do some brands choose No-Bypass?

Simply put, a no-bypass system takes less plumbing and labour, which means it is a cheaper option. This reduces the cost and increases the profit margin for the manufacturer.

Spa World will not compromise safety for profit.

So, Which System Is Better?

If you're choosing a spa and safety is a top priority (especially with young children in the water), then a bypass filtration system is the clear winner.

Bypass systems, like those used in Vortex^®, Fisher^®, and Jacuzzi^® Spas, are designed to reduce suction risks, protect your pump, and keep your spa running safely and smoothly, even if the filter gets clogged. They're a smarter, safer choice that gives you peace of mind, not just performance.

At Spa World, we believe spa ownership should be as relaxing and worry-free as the soak itself. That’s why we only sell spas with fully approved bypass safety systems, engineered to meet Australian and New Zealand standards.
