Plastimo Neptune 2000 Gas leak

[Bob Court]

I have a Plastimo Neptune 2000 cooker in my boat. It's been working fine until one day when I came on the boat and turned on the gas valve(regulator) above the Calor Gas cylinder only to hear a rush of gas coming from the cooker. It appeared to be coming from the control knob that lights the grill. It doesn't matter if the knob is turned off or on.
My question is..... Could it be that the regulator which is attached to the gas cylinder be faulty causing to much pressure to be released and causing the gas leak?

It seems more likely that it is a fault within the cooker itself. Is it relatively new or old and rusty?

It's possible that the diaphragm in the regulator has perforated, how old is it? It's cheap to replace and should be along with the hoses, there should be a date stamp on it.

I bought the boat less than a year ago so it could be very old. I'm popping on the boat tomorrow so will check the date on the regulator.
Thank for the advice.

Yes I imagine it is quite old. Its just that there was such a loud rush of gas as soon as I opened the regulator which makes me suspect (hope) it's the regulator.

Bob, if not this might be useful: Gas valves and thermostats

Thanks for the info.

Thanks for the info.

Update.....I changed the regulator for a new one and the cooker is now working. Obviously the old regulator had developed a fault and caused the gas pressure to rise.
I always turn the gas off when leaving the boat but if I hadn't then the gas would have leaked and filled the bilges and that doesn't bear thinking about!
I must admit that the regulator was old and didn't have a manufactures date stamped on? I thought regulators had a safety device which prevented this sort of thing happening?

I would urge anyone with an old regulator to check if it has a date stamped on it and if not or it is out of date then consider replacing it for a new one.

Regulators for boats should have a pressure relief fitted. Normally this seems to be a small bit of white plastic tube on the body of the regulator.

Edit bit. Buy GasBoat 4001 Marine Clip-on Regulator SOCAL Southampton a bit like this.

Glad you got it sorted and worked out the problem. I need to change our regulator which I'm embarassed to say is a long way past overdue. Googling you tube video of failed regulators is educational. Have you considered fitting a NASA gas monitor? That is also on my shopping list. The Bubble leak detector that is often mentioned won't fit in my gas locker so is not on my list.
