Make a Leak Detector for $25 [Make]

Jason Fitzpatrick is a warranty-voiding DIYer who spends his days cracking opening cases and wrestling with code so you don't have to. If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). You can follow him on if you'd like.

    Mirroring Matt V. I purchased a leak detector from Amazon.com for just under $10 after I put in my under sink reverse osmosis system. It detected a leak serval weeks later from a bad section of the seal on my undermount sink. It is very reliable. $25 DIY is a waste of time, money and resources.

    I bought two water leak detecters here in the UK at poundland for £1 each at a guess 70 cents each no disrespects intended, but not really worth making, and they also worked when i had a leak
    ( i thought i had a cricket in the House) LOL
