    How do I remove my water pressure switch (for Pentair Mastertemp 125)?

    I'm trying to pull this thing, turn it, but it won't budge. The instruction manual doesn't say how to actually remove it. This is for winterization. I believe this is the switch (or similar): https://www.amazon.com/Pentair-470190Z-Pressure-Switch-Replacement/dp/B008HLQMZ6 Thanks!
