There's a tool for everything, but do you really need that tool if you're going to use it once or twice in your lifetime? If you're like me you must have that tool...like all of them! However, that's not going to stop us from trying that "whatever's around me I'm going to use" method. Take this tub drain for instance. Usually these things get stuck from sitting there for decades and it takes quite a bit of force to loosen one up. Here are multiple ways that usually work. 1) Big screwdriver and a wrench. Place the wrench in the cross beams of the drain, the screwdriver in the wrench and lefty loosey. This method broke the cross beams. 2) Hammer and leverage. Use the nail puller end of a hammer, place it in the drain pull up and lefty loosey. This method slipped. 3) Place a 32mm socket on a high torque hammer drill, wrap electrical tape around it, then place a drain, press down hard and left loosy. This method usually works but man this thing ain't budging! 4) Well, guess we gotta use that special tool. A drain puller has a nut on one end. You place the tool inside the hole and as you rotate the nut lefty loosy the metal grip expands inside the drain making it grip. The harder you tighten left the more the tool grabs the drain. At this point you can you usually place your 32mm socket on the nut and use it with your hammer drill but even doing that this thing wouldn't budge. In the end it was the tool and a long adjustable wrench that finally loosened this guy up. Once you've got it out. Pull the rubber seal, clean the area, replace the rubber seal, apply plumbers putty around the new drain and righty tighty! You're done!
