The Advantages and Disadvantages of Ceramic Disc Taps

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!

Wireless Access Points: Thin vs Fat

Wireless LAN Switches: The Best Solution

There are two types of wireless access points Intelligent (Fat) and Thin wireless Access points. A fat wireless access point has everything it needs to handle wireless clients. A Thin wireless access point is basically a radio and antenna that is controlled by a wireless switch. If you deploy several Fat wireless access points they need to be configured individually. With thin wireless access points the entire configuration takes place at the switch saving you time and money.

Wireless LAN Switches provide many benefits:

Wireless Mobility Intelligent access arent managed in a central location which means there is no third party monitoring the movement of a user. If a user moves to another work area traditional wireless access points have a hard time passing off the user to the new access point. Thin wireless access points are controlled be the wireless LAN switch who will manage the users movement.

Security- Using the wireless LAN switch the administrator can check logs, configure is security settings, make group polices for wireless users all in one spot. Also built in to many wireless LAN switches are RADIUS servers which will give another layer of security on top of your encryption policies. In enterprise wireless networks the administrators biggest fear is rogue wireless access points. Wireless LAN switches can detect when a new wireless access point comes into the area and decide if it is a trusted or non-trusted device.

Placement Power over Ethernet is another great feature of wireless LAN Switches. Power over Ethernet eliminates the need for an power outlet to be near the wireless access point. This saves your company money by not having to install new power outlets. Also this improves security by not having the wireless access points within easy reach of passerbys.

If you are deploying a wireless LAN for a company I would be scared if you dont utilize wireless LAN switches and wireless thin access points. The upfront costs of these products are more but your total cost of ownership will be less than having to administer each wireless access point separately. To sum it up home owners should stick with Fat access points and businesses should use thin.
