Hello, good morning, it has been a while since the key in the middle of the shower does not work well, it always loses by ariba or below, and I want to take it out and I CAN'T! I tried with French parrot beak, that key that has a thread under the handle to press well and there is no case! and I'm starting to break into the hex where it grabs to loosen. Is there a trick to loosen it? I already tried to squeeze a little more to see if he drained and nothing.

Hi. Apply heat with a heat gun and it will loosen. If you don't have a heat gun, do it with a hair dryer to the fullest. Dilation will make it simpler to remove. They usually stick with tartar over the years. Regards
