Do You Need to Service Your Regulator After a Long Break? Here’s What You Need to Know

Scuba diving is an exhilarating experience, offering a unique glimpse into the underwater world. However, as with any adventure sport, safety is paramount. A key component of your diving gear is the regulator, a device that controls the flow of air from your tank. But what if it’s been a while since your last dive? If you haven’t used your regulator in over 2 years, is servicing necessary? Let’s dive into the details.

Understanding the Importance of Regular Servicing

Why Servicing Matters

Your regulator is essentially your lifeline underwater. It reduces the high pressure from the scuba tank to a breathable pressure, delivering air only when you inhale. Given its critical role, ensuring its optimal function is not just important – it’s essential.

Deterioration Over Time

Even when not in use, the internal components of a regulator can degrade. O-rings and seals may dry out or crack, springs can lose tension, and lubrication can dissipate. This deterioration can compromise the regulator’s performance, potentially leading to malfunctions during a dive.

The Recommended Service Interval

Manufacturer’s Guidelines

Most manufacturers recommend servicing your regulator either annually or bi-annually or after every 100 dives, whichever comes first. However, this can vary, so it’s crucial to consult your specific regulator’s manual for exact guidelines.

The Role of Inactivity

Inactivity can be as harmful as heavy usage. During periods of non-use, contaminants like salt, chlorine, and sand, if not thoroughly cleaned prior to storage, can cause internal damage. Moreover, the stagnant air inside the regulator can lead to corrosion and bacterial growth.

When You Haven’t Dived in 2+ Years

The Need for a Thorough Check

After a long hiatus, it’s not advisable to use your regulator without a professional inspection and service. Even if it appears in good condition externally, internal components may not be functional.

What Does Servicing Involve?

A typical regulator service includes complete disassembly, cleaning, replacing worn or outdated parts, reassembling, and adjusting to ensure proper function. It’s a specialized task that should be done by a certified technician.

Cost of Servicing

What to Expect Financially

The cost of servicing a regulator can vary based on the model of the regulator, and the extent of service required as well as additional parts which may need to be replaced. On average, you can expect to pay between $75 and $150.

DIY Maintenance: A Cautionary Note

While regular at-home maintenance like rinsing with fresh water after use and proper storage is important, internal servicing is a different ball game. It requires specific tools, knowledge, and skills. Doing it yourself without proper training can lead to irreparable damage or dangerous malfunction.


Returning to the underwater world after a long break is exciting, but safety should always come first. Servicing your regulator is a critical step in ensuring a safe and enjoyable dive. It’s not just about the regulator’s performance; it’s about your peace of mind.
