Our Whale Elite tap was leaking from the centre, we took the red and blue plug out, used an Allen key to undo the little nut inside and remove the lever, remove the top part of the chrome part by hand then using a spanner undo the washer holding the cartridge in place, once this is free remove the cartridge, you can inspect the 'O' rings on the bottom for any damage, if there is no damage to them open the cartridge up (there is 2 little clips that need pushing in) and you should see if there is a crack, if there is then it needs replacing. You can order the replacement cartridge from caravan-components.co.uk for £5.00 plus £3.50 delivery, look for ceramic cartridge valve 35mm for lever mixer taps, alternatively like we did check ebay from the same company for £6.80 free delivery. Very easy to take apart and fit.
