Help please Marshall gas regulator for 2 bottles

[TQA]

My boat came with a Marshall gas regulator which has connections for two gas bottles and a slide switch on the back of the device with the two connections.

I use it with two bottles connected and only one turned on.

I was dismayed to find that if I remove one bottle for filling gas leaks out of the connection to that bottle continously.

Is this normal? Is there any way I can use it with only one bottle at a time connected.

So far I have always been able to get the empty bottle filled within a day but there are places where it can take a week.

I am not familuar with that particular set up but on campers that slide switch controls which bottle you draw from. If the switch can be turned to the bottle that you are using the other bottle should be available for refilling.

hope this helps

keep safe

It leaks gas from the disconnected side regardless of the switch position if the other bottle is on.
