I'd had a slow leak in a rear tyre that's been a nuisance for a few months. Depending on how I park, I need to reinflate every 4-5 days, and it rarely drops below 20lbs.
Slow leaks are hard to find with the "soapy water" method, particularly once the tyre is off the car and pressure drops due to the car weight being removed. I've been keeping my eye out for one of those kids sea shell sand pits/pools on hard rubbish for weeks. Yesterday I found a massive pot-plant shallow tub. It's incredibly PERFECT for a tyre submersion!!
It took about 10 seconds to find the leak when submerged. So good. What a great find!! Very pleased. Hard Rubbish FTW yet again.
