Try and give a make and model and possible year of your caravan! Someone with the same caravan may at some point have had the same problem and they could point you in the right direction. Personally we traded in earlier in the year our Bailey caravan 12 years old which we had from new, the shower tap never leaked as it had never been used, but the kitchen and bathroom tap bothed lèaked at some point due to cartridge problems. Did'nt cost much to fix but it might not be the cartridge in your case.
