Can I please remind everyone, as is required from time to time; This is a Plumbers forum, as it says at the top of the page. To be a Plumber you must complete an apprenticeship, so, will all the CC/CCCs & DaftyDIY'ers leave without delay. As close personal friend of Steve, he has asked me to try & clear out some of the trash that has started to block up the threads here. Please close the door behind you, you know who you are!!!
