Hey, I've got a Baxi Combi 105 HE, and there's a component at the bottom that drips water. Not a lot, I'd say 1 drop every 10 sec, but annoying though. Here's a screenshot from the manual with the part I mean: Is this something I can fix myself? I can do basic plumbing and central heating DIY stuff, but I'm in no way an expert. Since a boiler is water, electricity, gas and combustion altogether I'd rather not mess around with it. Thanks!
