I’m fascinated by ventilation dampers and how they solve serious temperature issues

I love it when you find a cheap solution to an expensive problem.

I had a bathroom sink that kept leaking water around the edges of the porcelain.

When it was installed, it was placed into the open hole and the edges rest on the countertop. Whenever water gets over the edges of the sink it pools on the counter against the porcelain and finds its way down below. If you leave the problem long enough, water soaks into the wood below the sink and causes it to swell. This entire time I thought I needed a different sink to prevent this problem. I had no idea that it was the result of something simple and cheap. I spent no more than $10 at the hardware store on a tube of silicone caulk. Apparently the sink was supposed to be sealed with caulk from day one, but the plumber either forgot or purposefully neglected to do it. Once I sealed the porcelain to the countertop, I never had leaking issues again. I had another problem recently that made me fear an expensive repair job. My house has increasingly worse temperature problems. It doesn’t matter if I’m running the air conditioner or the furnace, every room in my house is a different temperature. I worried that I might need new ductwork altogether, which can cost up to $4,000 or more. It was satisfying when my heating and cooling contractor offered to install a few ventilation dampers which are like adjustable valves for your air system. You simply open and close each damper to distribute the air equally throughout the entire house. It takes an HVAC professional to adjust the dampers to equalize the temperature throughout.
