We have been concerned about the number of gas items which have been out of date when a van has been brought in for a service. A propane regulator on one van brought in to us in 2019 was dated 1979. You can see the date in the centre of the regulator pictured below. As these should be changed every 5 years, it was well overdue. Please remember that although these may look fine from the outside, there are springs and a rubber diaphragm inside which will deteriorate over time.
A Truma regulator is also dated on the label, as you can from the next photo. At the bottom of the sticker it says 18, meaning 2018. Truma regulators need to be replaced every 10 years.
Another style of two-stage regulator (in this case a Cavagna) have a date etched into the metal. In the photo below you can see '0319', which means that it was made in March 2019. These, and single-stage regulators, should be changed every five years.
Gas pipe is also dated, and should be replaced every 5 years. The date 02/19 can be seen on the orange LPG pipe in the next photograph. The pipe can crumble internally, which results in the gas gently escaping and leaking into the habitation area.
Finally, gas pigtails are also dated on the pipe. In the last photo, the 'PROD DATE:2019' can be seen. These rubber hoses should be replaced every 5 years, unless they are made by GOK or Truma, in which case it is every 10 years. Of course, if any hose is split or cracked, it needs replacing immediately.
All these products are available to purchase at our on-line shop, or in person.
