Just like to say that Bob and Timm are great. Their product works well and they are honest and have a great work ethic. I rarely recommend others because if they disappoint it can reflect badly on you.
That being said, I have recommended Timm for years. I have bought his product and it truly does allow the rain to drain from your Lanai without letting the bugs get in.
Also, Timm also sells and installs Billybibs....if you are tired of pulling a hose all across the outside to get a hose into your lanai, then pulling through the screen door opening, letting bugs, etc, get in.....you need a billybib! We love ours. If you do not know what I am talking about, check them out at

In one sentence- Great folks-Great products-Great service.
