    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
