You turn on a faucet and all you get is a trickle or streams squirting left and right. The problem might not be in your faucet at all. It might be the small device on the end of the spout called an aerator. Its purpose is to mix air into the water stream. It provides an even, splash-free flow, but its screen traps all kind of debris, from small particles to lime and calcium deposits. When this happens, it gradually cuts the flow, leaving only a dribble or weak pressure. The solution is easy. First unscrew the aerator tip. If it is hard to get off, wrap it with tape or a soft cloth first to protect the surface. Then use pliers for a better grip. Once it's off, remove the gunk from the screen and screw it back onto the sprout. It sounds terribly simple, but you?d be surprised how many homes have bad water delivery for just this reason, and because folks forget to do a simple thing like cleaning out the aerator every so often. Try it, you just might see a big difference. And that's the On The House tip for today.
