I have a PV3 pop ups that need to be taken out and cleaned or replaced. I bought the tool which is hard plastic and has 4 tabs that fit into the top of the pop up. You then are supposed to turn counter clockwise about a quarter turn. The first one I tried would not budge going counter clockwise. I then tried clockwise and same result. I tried counter clockwise again and gave it a bit more muscle and the tool broke. they make a metal tool with the 4 tabs, but it costs about $80 bucks. Anyone else run into this problem? Any suggestions are greatly appreciated.
