B
- Back-Placed Drain Holes
If you plan to have garbage or recycling containers under your sink, choose a sink with a drain hole that’s placed to the back of the sink, or an off-set drain hole, rather than one in the center of the sink. This position places the pipes closer to the back of the cabinet therefore freeing up space.
- Backflow

- Ceramic Disc Valves
Consists of two disks in a sealed cylinder that allows the water to flow when aligned. This system is extremely durable - rare leaks are usually linked to the neoprene seals at the water inlets. Repairs are easy. Ceramic disc valves work better as time goes on. They’re very smooth and almost as hard as diamonds. Air can’t get between them, so they cling like magnets. That’s what makes a tight seal in the valve. Each time you turn on the faucet, the discs glide back and forth and get a little more polished.
- Ceramic-Disc Faucets
Also referred to as Washerless faucets. This style of faucet is the most maintenance-free. It has two ceramic discs that move against each other, blocking the water or allowing it to pass through. The more you use the faucet, the better it becomes, because the movement itself makes the discs smoother and the seal becomes more watertight the flatter the discs become.

- Choosing a faucet for an existing sink
When replacing and existing faucet, choose a style that requires the same number of holes in the deck of the sink as the one that’s being removed or less than that number. There are cover plates available to hide any holes you no longer need. One-piece faucets, with an integrated handle and spout, need one hole for the handle & spout piece, and if there’s a separate sprayer you’ll need another hole for that. Traditional faucets, with hot and cold taps, require three holes for the taps and spout and a fourth for a sprayer and if you want a soap dispenser you’ll need another hole.

- Contaminants
Contaminants - Taste and Odor - smells of chlorine or rotten eggs or tastes bad, a granular activated carbon type filter would absorb these contaminants. Rust and Sediment - Little particles that look like dirt or sand may collect at the bottom of a glass or when you turn the water on in a bath, they are easily collected by particulate filters. Whole house particulate filters can be easily installed to protect not only your drinking water, but also appliances such as dishwashers and ice makers. Water filters are not effective against clear water iron, which can leave red stains in tubs and toilets; a water softener is required for this problem. Bacteria or Parasites - usually in well water where bacteria and parasites occur naturally in clear water supplies but may be the result of the water supply being contaminated by sewage and wastes. They can cause illness and are a serious hazard to the young, elderly or those with immune deficiencies. Water filters are available with various filter cartridges which are effective against many of these contaminants. Lead - Houses built before 1986 usually have pipes joined with lead solder. Your municipal water system may contain components that are soldered with lead. Lead contained in water is tasteless and odorless, but should be avoided as much as possible. It can be most effectively removed from your drinking and cooking water by installing a lead filter directly under the sink in your kitchen. This filter placement assures that even if you have lead in the pipes of your home, it will be removed from your drinking water. If you are concerned about the possibility of lead in your water supply, you should have your water tested by an independent laboratory.

I.e. you will need one to three holes to accommodate the taps and spigot. More holes will be needed for a hot-water dispenser, a spray accessory, if it’s not integrated into the faucet, or a built-in soap dispenser. There are accessories available to cover any un-used holes so you can buy one with more holes if you’re not sure what your requirements are.
