Plumbing! It was about €26 in Sallynoggin but I'm not sure if it was 10m - it was definitely close.
I got a wider coil in Chadwicks and it was really easy to make. It took about 30 mins total. Just make sure you have the right size band to fasten the hose to the pipe - I didnt have the right one on the outlet and it gave a bit of a squirt when I first used it!
