I,m just wondering were the popcorn people are now, is it the fact i,m in the trade as a plumber and the so called experts on here can,t get away with stupid comments coz i don,t like stupid comments and they can,t deal or want to deal with a non DIY guy because i,ll be honest i just asked a simple question, and the first few answers were lets say taking the ****, is it any wonder why people don,t ask questions, people ask questions from people in the trade because they know that you guy,s know what your talking about, to have comments like ohh i wonder how many pages this is going to go over, i,ll get the popcorn out, or he,s prob looked at a site and being told that,s the best system to put in, thats just being a BELLEND !! i,m appalled that trades people actualiy act in that way on a forum that is DIY and people ask for help, you guys could save these people from spending too much cash if their idea is wrong or unsafe and point them in the direction of a specialist that saves money or lives.
