Thankyou for this - easy to follow instructions, and yes, the drain was full of gunk. Couldn't believe how much water came out! I suspected it might be blocked when I started getting water in the footwell. Mind you, there's been a LOT of rain recently. I bought the pipe bending spring from Screwfix, but instead of a bootlace and tube, I adapted a lambing aid I found in our local farm supplies shop, cut the Y piece off, rerouted the flex and it did the trick nicely. Thanks again!
