To remove & clean this pigtail, should I rotate the pigtail with the pressuretrol still attached? I'm afraid of water inside the pigtail getting inside the pressuretrol when it's inverted. I'd like to keep it upright through the whole process. It's too close to the face of the boiler to be simply unscrewed off the pigtail.
I know to not touch the two screws on the mounting plate under the pressuretrol. Would the hex nut directly underneath that plate allow one to remove just the pressuretrol? Then the pigtail could be rotated and clear the gauge without removing it. The lwco is easy to remove if that gets in the way... I'm really stymied here!
