Bought a $47 leak detector on a hunch and it found a washer leak in 10 minutes
I picked up a UEi refrigerant leak detector last month for around $47 after guessing at a Whirlpool top loader for two visits. The first unit I got was dead out of the box, so I returned it to the supply house on Grand Ave and swapped it for another one. Second one beeped right away near the drain pump, saved me from pulling the whole tub apart. What cheap tool has actually paid for itself for you guys?
