aye as above,the gardeners one,had it laying about so stuck it couple inches before t piece.
Do top windows nipping hose between windows,
collapse pole,
turn tap,
water of,
grab another part of hose,
do bottoms and turn water of.
Really simple,the a/d hose works good for this.
I still really like the a/d though,good bit of kit but this works well too,just another option.
