I can't figure where the leak is in my kitchen cupboards, but there is clearly a leak under the sink as we have a horrible musty and mildewy smell under there that I just can't get rid of. My husband has looked and looked and he can't work out where the leak is. The smell is so gross when we are preparing meals so I can't wait to get rid of it. It's definitely time to get a plumber in so we can get back to using the kitchen without gagging. This blog is about locating pesky leaks and drips.
