    Don't know if this has been mentioned before and I know its a tad early but I picked up this tip to help clear the hot and cold water pipes when preparing for the colder weather. Drain down as usual and using an inflated balloon attach it to each tap and let the balloon deflate hopefully blowing any residual water out of the tap and lines. Tried it last year and it worked ok.

    I wonder if you filled the balloons with Helium, it would make the pipes squeaky clean ?:whistle::whistle:

    Also leave all the taps open , then if any residual water does freeze it can expand along the pipe instead of splitting it, worked for me for a number of years.

    Forgot to say but leave taps open in mid position to cover both hot and cold feeds.

    I just attach the compressor to the shower hose, just make sure the other taps are open. :)

    I also just blow down the shower hose. Taps open and the shower head on the floor of the shower so any water can drain out. Grey tank empty and the drain tap left open.
    I did have a problem last year though as heading to Spain in February the drain tap froze open so I was an involuntary grey waste dribbler for a day till it thawed.
    Leaving it open helps to prevent smells as the anaerobic bugs responsible for bad tank smells don't like fresh air.

    I fitted a Floe device and was very surprised how much more water it purged from the system after the normal drain down. The inflated balloon probably achieves much the same and would be cheaper.

    Floe make devices to help drain down. My version allows you to connect a tyre pump to the system but there is a version that includes a compressor. I found it on the internet.

    I wonder how many people do nothing, other than drain down, and get away with it?

    No idea but l use a 600w greenhouse heater on frost setting. I've been doing it since our caravanning days. My off-season is mid-November to the first week in March minus a week just after New Year. There aren't too many nights during a 'normal' Winter where the temperature is below 5 deg C.

    Sounds like a great idea except mine has a one way valve fitted so not quite sure how I will get all the water out of the pipes
