Delta's DIAMOND Sparkles

Yesterday's Product of the Day was on Delta's new DIAMOND Seal technology. I promised the scoop on what it is and what it does, so here you go.Delta Faucet Company recently unveiled its Diamond Seal Technology, a new water delivery system that eliminates contact with potential metal contaminants such as brass, copper or lead, keeping water as pure as it entered the faucet.
The DIAMOND a closed system, meaning there are no dynamic seals to wear out. Water never enters the top half of the cartridge, eliminating the possibility for leaks under the handle. InnoFlex waterways are made using the company’s blend of cross-linked PEX.
The valve is an integrated ceramic valve cartridge featuring one ceramic disc and one diamond-embedded ceramic disc. According to the company, as the two discs in the DIAMOND valve move against each other, the diamond-embedded ceramic disc constantly polishes the uncoated ceramic disc, removing calcium and mineral deposits and ensuring smooth, consistent operation over the life of the faucet.
What’s really cools is that all the parts plumbers need to rough one of these in is located right there in the box. 
The supply lines are over three feet long, so you can go ahead and snap them directly to the hot/cold shut-off valves. The lines can be coiled out of the way or cut altogether using ferrule inserts.
For those of you with safety in mind, the handle limit stop is easily accessible and can be set by clicking the lever over to + or – for temperature settings.
The system satisfies California statute AB 1953, mandating that drinking faucets contain less than 0.25% lead by 2010.

I just had a plumber install a 470-DST and it is a great faucet. The handle feels really good and it doesn't stick like my old one. I am trying to find out more about the diamond coating process. Hopefully they can make synthetic diamonds to help bring the cost down.

The diamond material used is in a layer nanometers thick. The sheer act of ceramic-on-diamond keeps the system going. The cost shouldn't be all that prohibitive, given the time you'll save in installation. Simply put: it's a great system and the operation is silky.

Seems like it would cost less with all the copper gone and less brass being used but they charge the same or more. What's up?

I was just reading about the "diamond embedded ceramic" when I went to Delta's special website diamondsealtechology.com where they described the diamond like coating is placed on a layer of Tantelum, not on the ceramic at all.
they also say they have reduced the the number os leak points. I beleive the good old Delta ball system has 7 leak points at different seal locations. Now they have 13 based on the crossection on their website.
What else are they fabricating? Someone needs to dig into this further to find out the truth.

I can't find one, can someone point me to a website or distributer that sells the DST equiped faucet.

Factsonlyfromplumber,
Actually there are no leak points in the valve. It is a closed system. There are NO dynamic seals, the only seal is between cartridge the gasket between the PEX “puck”. You need to take another look at the x-section the valve; it is not flooded; the only water contact is between the plates in the valve. That means there is one leak point between the valve and the “puck” and only one on each supply line at the rough in. So you could not be more wrong. This valve blows away anything that Kholer has ever dreamed of.

There is a static silicone gasket seal between the valve and the puck. It will never break down or lose its shape as opposed to other gaskets. Also the puck that's around the Pex-C lines is molecularly bonded further eliminating a leak point. Delta suggests not cutting the Pex lines due to ferruls possibly blowing off under pressure if it is not exactly straight. They suggest simply coiling the lines.
