A, the color choice: the current market taps to stainless steel chrome is the most common, there are some less common colorful faucet. Such as bronze, gold. Stainless steel chrome is generally based on simple style, bronze is generally Chinese-based, golden faucet with European style, supporting the entire decoration of the extravagance.

Q: I would like to give a sink and faucet the appearance of having plumbing for display purposes. Is it possible to use a fountain mechanism to create that effect. I'd like to be able to turn a handle and have the water flow, then drain back down into a basin to be pumped through continuously if left on. but able to be shut off by simply turning the handle back to the off position.: It may be less expensive to buy a 12vdc RV pump but then you'll need a car battery or 120vac/12vdc converter. Won't hurt to check w/the pump mfg to insure your no flow (valve closed) time won't hurt the pump. Install a filter on the pump suction line and you should be good to go...

Thank you ~ ~ more: 59 copper faucet lead content of about 1.8 percent have been low lead faucet, in line with GB, 62 copper can do the lead, the line that DR copper, the general production is only for Europe chu hair to avoid the seal, The DR copper with anti-dezincification element arsenic, corrosion performance is better, (arsenic is toxic substances) so have their own interests. Can buy low lead faucet is pretty good, the market lead content of more than 3% should be a lot
