    Does your calorifier have a PRV (it should).? This may be leaking.  Try twiddling the knob on the PRV.

     

    Look at the outlet from the PRV to see if it is weeping.

    Or could be pump valves as David above says.

    No drips from the PRV would indicate a problem with the pump if no leaks are apparent.

    I emailed Barrus a couple days ago but no response....I'll do as you suggest and remove one and measuring it! Hopefully there is another manufacturer that matches the spec....Thanks

    There should be some identification number on the plug. Then try EBay, I was quoted around £25 per plug from a Diesel engine servicing company, got exactly the same plugs for £1 apiece!

    No, and without a connection to the shore side mains there is no way you can wire on to the boat that will do anything at all. They have no use until the boat is connected to the mains earthing system. That does not mean that a mains fault on an adjacent boat can never cause current to flow through your hull but a GI or IT can not stop that happening when the circumstances allow it, but it is rarer.

    👍 Excellent advice, as usual. Thanks Tony.

  4. Friends abroad swear by this rust treatment. Totally different to Vactan. It doesn’t turn rusty steel blue/black, but claims to penetrate the rust, drive out all moisture and prevent further rusting. It can then be overpainted and even ADDED to any oil based paint to protect the metal and also “ease” the application by extending the flow and drying times. Anyone used it?

    Blockage/restriction in the feed pipe from the regulator to the burner pot seems most likely.

    I removed the scraper arm, put a plastic tube on the “valve” and blew down it. There was a small amount of gunge that came out when I blew which, as you thought, must have restricted the supply of fuel from the regulator to the burner pot. 
    I also cleaned the slot in the valve with a cocktail stick as suggested by Ex Brumaire and the combination of the two has resulted in a nice blue flame. Job’s a good’n.

    Cheers👍

    Taking off the lid, presumably off the oil control valve, allows the metering column to pass more fuel than the set amounts. Remove the metering column and clean out the slot, inside and out. As with carburettors, do not use a rigid pin or wire to clean it. Break a matchstick to give a sharp point and push into the slot, both inside and outside the tube.

    Will do. 👍

    My experience exactly.

    I did everything else and had fuel coming through on highest setting but as soon as it was reassembled it burned with a smoky yellow flame, very sooty.

    I eventually found the blockage in the feed pipe as the design of the soot scraper on the inlet causes crud to build up in the pipe.

     

  8. For some reason my old Dutch is not getting enough fuel through. Took the lid off and removed the float mechanism and plenty of fuel comes into the vapourising pot if the brass“valve” is at its highest position, so it’s not a fuel problem.

    Cleaned the filter and the regulator scraped the inlet scraper. Do the regulators need adjusting after many years of use? I’ve never adjusted any of the sealed screws so I’m puzzled.

    Apart from the fact it is only 22mm pipe I can't see why it would not work. Some say 22mm is sufficient but I understand it needed 28mm plus. Do you have a sketch of how it was laid out?

    Is there any chance you did not pre-mix the antifreeze and water before filling the system.  If you did not that may very well   prevent gravity circulation.

    Actually it is 28mm but it could be that I didn’t pre-mix the anti freeze. Good point. I’ll have a look at draining the system.
