    Onboard gas supply Problem Manchester Tank Systems
    Came across fellow campers Roy and Sue (non Funsters as yet)
    They have been full timing in their old Fleetwood RV for a number of years, got all the manuals but not a clue about mechanics, but learning as they go.

    In Spain for four, years, and because gas was unobtainable to supply the main onboard gas tank for the utilities.
    They have been using bottled gas, by disconnecting the supply AFTER the (what I believe to be) an electric gate valve. No problem there.
    The problem was that they forgot to cover the, now exposed feed pipe junction.
    Fast forward four years, and upon attempting to re-connect found that insects had made their home in the open pipe end, this was cleaned out carefully and before re-connecting the gas (1/4 full) the main gate shut off valve was opened in an attempt to purge any residue. No Gas?
    I plead complete ignorance of the system of an RV and ask any of you guys as to what can be done to help out, have a good supply of tools that could possibly do the job.
    I am thinking maybe the electric valve may be faulty or jammed
    (Told it is automatic?) |Don‘t want to bugger things up
    Over to you guys

    The electric valve that is in the picture, is what I'd refer to as a solenoid valve. It consists if a coil of wire which when energised opens the valve to allow gas flow. I'm presuming it's 12v (if it's mains voltage don't touch it unless your qualified electrician).

    So if it's 12v. Isolate the gas supply at the tank. Get someone to touch the solenoid body with their finger tip while someone else switches the power on and off to it. If the solenoid is free you will feel it clunk on and off. If so, then it's a good indicator that it a blockage in the gas pipes. If no clunk is felt (most likely outcome) then the solenoid is jammed and needs replaced or the voltage is not reaching the solenoid. You can check for voltage at the solenoid terminals with a small multimeter, should see 12v indicated when solenoid switched on.

    If it needs replaced look on Ebay, but make sure you get a replacement with same operating voltage and pipe threads.

    It is a solenoid valve they do tend to stick if not used I would suggest as another funster mentioned, look on e bay or find a gas engineer qualified to check it for you:thumb:

    thanks for the input guys to state the obvious we had already come to those conclusions ,ebay not an option we are away again tomorrow and were hoping for a solution to help out before from someone who actually knew this system cheers

    I suppose you have checked that there is some gas in the tank, after four years it may have just trickled away :thumb: then again I am no expert:Doh:

    Oops engage brain before keyboard just noticed quarter full
