Taps drip. It's inevitable, like death and taxes. Traditional taps seal using a rubber ring screwed down over the end of a metal pipe. Sooner or later the rubber is going to go hard, split or just wear away and it will no longer seal. Then water seeps through, and the tap starts dripping. Left alone the problem gets worse as the water wears away the valve seat. Then you'll have to either re-grind the valve seat(Do you own a valve seat re-grinder? Who would?) or replace the tap. Tedious in either case. But, it need not happen. Many taps now use ceramic discs.

Method of Operation
Instead of creating a seal by forcing a rubber washer onto the end of the water feed pipe, they use two ceramic discs each with matching slots in them. These are held over the end of the water feed pipe. The lower disc doesn't move while the upper disc is turned over the lower disc by the tap head. water will only flow when the upper and lower slots match up.

Advantages
There are a number of benefits to this arrangement. The most obvious is that ceramic discs are much harder than rubber and much more resistant to erosion by water seepage. Hence they have a much longer life before needing replacement. Additionally, because the water flows between the two discs, the discs erode not the metal of the valve. Also, because of the way the discs are arranged, the taps go fully on with only one quarter of a turn and tap needs only light pressure to operate. This light action has the advantage that they are easy to operate with the back of the hand if your hands are dirty and for people with restricted movement.

Where they are Used
The ease of operation and the long life mean that most good quality sink mixer taps have been made using ceramic discs for a while, but basin taps with ceramic discs are surprisingly less common. The more use a tap gets, the more attractive the use of ceramic disc technology becomes. This is doubly true in hard water areas, which can be murder on traditional taps.

Disadvantages
Everything has it's downside, and there are cons to ceramic disc taps. They do eventually wear out and are more expensive than old style taps and are not suitable for very low water pressure. Unusually, many of the manufacturers seem to use standard sizes, so getting a replacement is often straightforward. Because taps on basins can be either handed or not not, one can't always be sure which way to turn each tap on, this can be annoying! Lastly, unlike traditional style taps, which take a number of turns to be on full, you may easily turn the water flow on far more than meant. The unexpectedly vigorous water flow and splashing can cause water going everywhere, including over your clothes. Not Good!

We've all heard the predictions - Fifteen major atlantic hurricanes are expected for 2007, five of which are predicted to impact Central Florida. Certainly, nobody yet has forgotten the four hurricanes that inconvenienced us in 2004, nor can we forget the three storms of 2005. But before we look ahead to this coming season, let's stop and take stock of the lessons we've learned from our most recent experiences and prepare our children for this year.

In 2004 and 2005, we pulled together as a community and did all the things good friends and neighbors do when the chips are down. We shared food, water, tarps, and cell phones, and we took time to connect with the strangers across the street. We reached out to those in need and made some great new friends in the process. We hunkered down, we weathered the storm, and together we cleared the deadwood.

We became accustomed to the blue tarps, and fortunately, tarp city is almost gone. So what can we do to prepare for this year? Certainly we cannot change Mother Nature. After all, few mothers allow her children to change her. However, we have now learned how to live with her. And that is the first step towards a safe season.

The good news is that most of the things five hurricanes can damage have already been damaged and replaced. New roofs, stronger windows, and better structures mean less damage. The old trees are gone and the new trees are firmly rooted in their place. Our communities are now ready to come through the storm with minimal or no damage.

Yes, were ready. We all know what we have to gather, and for the most part, we all have our storm supplies ready. Sure, there are some things we can still do. For example, we can still have our plan of where to go when the phones are out. We still need to know where the closest shelter is.

Those of us with kids should consider going to visit friends or relatives when the next storm comes. After all, what better time is there to go on vacation than when a hurricane is in town?

Weve all discovered that cell phones work during the storm, and weve all learned that if you cant call directly to a family member, then we need somebody else to calla central friend or message boardsomebody out of town who can let everyone else know were okay. Dont forget text messaging, email and SMS. Teens and even young kids with cell phones are expert at these technologies. Chaos is the only constant in natural disasters such as hurricanes. The answer to coping with the sense helplessness chaos brings is to take control of some aspect of the disaster. Even if you know how to text message, ask your kids to help you or even teach you to use these technologies.

The key to feeling safe and not worrying about this years storms is to be prepared and to have a plan. Make sure your children know the plan, have practiced the plan and can implement the plan without you. Thats right, the key to security is knowledge. After 2004 and 2005, we have the knowledge and we have the experience. And as a result, well get through this years storms far easier than we got through last years.

So when the wind blows and the rain falls this season, well be warm, dry, and hunkered down. Well play games with our kids, talk with our kids and maybe even learn something about them as people. Well hold your children close until the sun shines in Central Florida again. After all, they dont call us the Sunshine State for nothing.
