    I recently had this problem, the drain valve on the cylinder was broken. I disconnected the top connection and siphoned out as much as i could then lifted out the cylinder. Is this the easiest way or are there other methods

    Nothing easier than that just make sure to hose reaches the bottom to drain completely, I do it that way even when there is a drain on the system its quicker.

    I always cut the cold feed to the cyl (somewhere higher than thetop mind) and feed me hose down it and syphon it out

    easier than try to get past the coil with a hose

    I always use a length of 15mm just taller than the cylinder then attach the hose so you know its at the bottom ;)

    I get my 15mm hole cutter, my hoover; and drill a hole just up from the bottom...

    No worries - takes two minutes to empty the bu.gger.


    Not much use afterwards though :rolleyes:

    There is an easier way but if I tell you then you will all want to do it and I will loose my commercial advantage.

    Same principle but a bit of 15mm Hep pipe - cheaper 'n copper and a bit more flexible.:cool:

    You only need a short length of copper shoved into hose. Its weight takes it to the bottom.

    2 other ways:
    a) Put yer hoover on blow on the top outlet, and water shoots out of the cold inlet pipe. Speedfit do some good 22mm to hosepipe fittings.

    b) Cut the cold inlet pipe off just above the top of the cylinder, and just shove it down sideways. Something will give and rotate. Then the water pours out of the pipe.
