On the 26th of June 2018 Huish Outdoors who now owns both Hollis and Oceanic announced a quality alert on both Oceanic and Hollis regulator 1st stages.
What's the Problem?
Put simply there's a small part inside some diaphragm regulators that can restrict airflow at low cylinder pressures, below 35bar/500psi. Here is Huish's official statement on the problem:
"There exists a possibility for the Hollis (and Oceanic) diaphragm style regulators sold or serviced between October 1, 2017 and May 25, 2018 with a new HP Poppet to significantly restrict airflow at low tank pressures (below 500 psi), posing a drowning hazard to consumers. Any regulator with the new HP Poppet must be fitted with the new style.
It is of the utmost importance that if you have a regulator model affected by this quality alert it be serviced and the pin replaced as soon as possible.
While no incidents have occurred, the possibility of an incident does exist. We strongly recommend that consumers take all necessary precautions when dealing with life support equipment."
Am I Affected?
Below is a list of all of the 1st stage models that may be affected and it is only those assembled or serviced between October 1st 2017 and May 25th 2018. If you bought one of these regulator 1st stages after October 1st 2017 or had your regulator serviced after that date then you may be affected.
I Have One of Those
Your next step is an easy one; and both Hollis and Oceanic have set up a dedicated web page so you can check your regulator serial number. Look on your regulator 1st stage and there will be a number laser etched onto it about 8 digits long such as 'EDX00175'.
Huish have set up these fantastic web pages for you to check if your regulators are affected and what to do if they are:
I Am Affected
If you put your serial number into the checker and it came back that you are affected or if you had your regulator serviced then you need to stop using it and either contact your nearest Oceanic / Hollis Authorised Dealer or Email Huish Directly with all of your details for further instructions.
Hollis and Oceanic have released these Q&A pages about the alert that may answer any of your questions:
What Happens Now?
if you're affected then Huish will recommend that you take or send your regulator to your nearest dealer who will take in your regulator and swap out the part in question or send your regulator to Huish for them to complete the work. This should take no longer than 4 weeks but be prepared to be without your regulator for some time.
The service itself to change the parts required shouldn't cost you anything but travel and postage costs may be incurred.
