Hi

We have just taken our Bailey Ranger 500/5 2007 for its anual service. Everything was ok with it when we last used it in October last year but during the service they have found that the gas regulator was blocked. I have read of the issues with the truma regulators on here previously but what is the fix. The service guy is fitting a new regulator and talking about a 90 degree elbow between the pigtail and the regulator that will stop if failing again.

Is anyone aware of this modification and does it work ?

Nothing to do with the gas hose, the problem is something akin to thin oil in the bottle propelled out by the gas. It's not present in all bottles so it's something of a lottery if you get a dirty bottle in the first place and then if it gets out ?

This oil has always been an issue but would pass straight through the older style 'single stage' bottle mounted regulator, it now gets trapped between the stages in the Truma supplied GOK 'two stage' regulator and blocks it.

Solution is to change the Truma/GOK bulkhead regulator to a 'Cleese' regulator, you can get these on their own from bes.co.uk for around £14. Anyone that reads caravan magazines can see or buy the same regulator advertised in a kit by Gaslow. The kit also contains a stainless butane/propane hose to replace the rubber one, the good thing about this hose is it will last 20 years.

Of course I have and the original report but it did not change my opinion one iota

In defence of those that did the testing, it's pretty obvious they would not be supplied with a 'dirty' bottle of gas to test, casting around and finding the same substance in the hose would seem a reasonable scapegoat; however, the original report itself cast doubt on this, as it's impossible for there to be enough present in half a meter of hose!!.

It's just a shame then they never gave a thought to ask the trade, then they would have been told loud and clear where to look, the problems been around a lot lot longer 2004!!

Thanks for the replies.

I have just got the van back and the new regulator is similar to the one in the top picture of Wizards post but the 90 degree connector is integrated. Hopefully this will sort the problem.

Yes thats the kiddy albeit it's gone up a bit, shows how much the pound has dropped?!

I'm not 100% sure it's the same fitting but it's designed for the purpose so it would be pretty silly not to be the same!

Looking on page 58, item 12673 would also seem a very useful extra bit of kit to spend some of the saving on?  

Yes found that gauge by accident looking for the correct regulator, my biggest gripe about this new system is if the high pressure hoses busts??

I've seen enough old hoses leaking under the old system to know it's going to happen sooner or later, especially as this new system passes into neglected old vans. That gauge though shuts off the bottle if a pipe should bust and so preventing what could be a catastrophic gas leak.

My hope though is that the powers that be wake up and put the regulator back on the bottle before it becomes an issue.

On the subject of pipe size, I'd be very surprised if a modern van has an 8mm main feed pipe, the odd very short van maybe, but most will have 10mm to supply enough volume of gas so all appliances can work at the same time
