Preventing Water Damage Under the Sink

[Andrew Jones]

I while ago I read a post on BP about someone putting slanted drip pans under the sink so that if there is a leak water flows on the floor it is reported by a renter rather than pool and cause water damage especially in a second floor unit. I can't find this post anymore. I have searched and searched, but can't find actual name of this thing. I checked at home depot and didn't find it. Has anyone used this type of preventative maintenance in there own units. Where can I find this thing or do I have to build it. A picture or a link would be great. Thanks
