i did as bob suggested after work today and no water came out of the drain screw.about half a cup drained out of the inlet connector instead!happy days!i think ill leave the drain screw alone as its a pain screwing it back in!
KLEAN07 have you never used hot wfp?i agree its not really needed.its a luxury!but i love luxury!!

ill be using hot every day from now on.it cleans quicker,hoses are a lot easier to manage.ill be able to work in -5 temperatures,its so easy to scrub snail trails and birdmuck off.im well impressed.
