So my mother wants to put a new set of bath taps into her house. When I turned up with flexibility hoses and a pipe cutter I was presented with this type of fitting to the bottom of the tap (see image) And that's the easy tap to reach, though accessibility isn't the issue. They looked like they were designed to be unscrewed by hand as I've never seen a tool that would unscrew that. I tried tapping at the "fins" coming out of the fixture with a hammer and an old masonry chisel, barely enough room to swing my hammer. Then I grabbed my slip joint pliers (totally forgetting that I had a pair of vice grips) and got some movement with that. I thought. Then I looked up and the 45° of movement translated to a 45° movement of the tap above. Is there a special tool for this. I was just going to drain the system, unscrew the taps, cut the pipe, add flexi hoses and attach them to the new taps, tighten everything up and voila ( I'm dubious about whether or not the new taps will fit as it's a single unit and the downpipes are smaller than the original fitting, but they can be moved to be slightly wider, but also slightly diagonal; however that's another story entirely), but these fittings nearly gave me an aneurysm, is this how older plumbers prank people doing DIY (well unpaid work as it isn't my house...)? Am I doing something horribly wrong.EDIT I was considering grabbing a cheap blowtorch to expand the metal a bit and heating the fittings up a bit then trying to tap them loose if there isn't a special tool. This is my first foray into plumbing (well except for fixing airlock, repairing ballcocks and stuff like that and fixing drainage pipes for grey water. It's TL;DR territory after this guys, unless you want to give suggestions on how to half a bathroom. After this I'll have a sink to do, which has nice bolts so I might go from copper to hose on that just because I dislike working with copper plumbing somewhat, I remember watching Canada's worst handyman (a must watch series) and seeing them have to use a blowtorch, flux and fittings (and the water exploding out of anywhere because they can't solder pipe, or listen to the guy instructing them) seems so backwards compared to compression fit hoses. And finally I'll be fitting a toilet, what fun. Elbow high rubber gloves on list of must haves.
