    Holder/Bracket for PMUP

    I have a PMUP in my ATO reservoir with a optical sensor near the bottom so my Apex will shut off the ATO and alert me when the water level drops. The problem is the PMUP tubing has some bends in it so it doesn’t like to stay standing and will frequently tip over, meaning it starts sucking air before the water level drops below the sensor. I’ve tried removing the bend in the tubing, but it has too much of a memory and keeps re-bending.

    Does anyone have any ideas for a bracket to keep it standing upright?

    Try heating up the tubing with a hair dryer and bending it straight. That will basically "reset" the memory of the tubing and then you don't need a bracket at all.

    You might be an engineer if...You have no life and can prove it mathematically.

    I tried soaking it in hot water - it helped, but there was still some memory in the tubing that gradually returned. I’ll try it again to see if it helps
