DELTA FAUCET DIAMOND SEAL TECHNOLOGY

This is a small video of a faucet that was sent to me by the Delta Faucet Company. I show the complete disassembly of the faucet and it's inner workings, design. Any questions about this new technology I will refer to my Delta rep as he is very well versed on this new product knowledge. I personally believe the Diamond Seal technology is cutting edge and will become a strong selling point for the Delta Faucet Company over their competition.

Hey my diamond seal valve is leaking on the hot side after 1 and 1/2 years of light use. We'll see how the warranty process goes I guess. I did try to tighten the valve. Didn't help. :(

@bluetrepidation - They shouldn't give too much issue and should replace that cartridge assembly at no cost to you, including shipping. When dirt enters these cartridges it gets between these two planes where the positive on/off occurs. I would rather see Delta go back to the tried and true, seat cups and springs. Inexpensive to repair, cartridge doesn't get pitched. That's where your cartridge ends up. Please let us know how it turns out!

BTW, I've been to the Delta Mfg. Plant in Indiana. Went years ago and saw how these faucets are made from the brass billet to the store shelf. Impressive.

I would like to see Delta stick to their design of brass and copper, and leave plastic for another brand and reputation. I feel strongly about this because my hands are on your product and others daily, and I know which ones are prone to failure. Delta is on the high side of quality. It's this latest move that has me thinking "cautiously".

It's an excellent faucet man. I work for Masco, the company that owns Delta. We have improved upon the ceramic disc technology. We have put a tough diamond coating on one of the ceramic disc. Everytime you cycle the faucet off and on, the diamond coating polishes the other ceramic disc, preventing any buildup of mineral deposits. The lifetime for a faucet is supposed to be 500,000 cycles, but our DST valve has been rated at 5,000,000. There are many more selling points to this faucet as well.

Hey thanks for commenting on my video. I had "concern" about those PEX risers that are built into the faucet. I don't doubt the quality of the DST cartridge. I spoke to my local rep regarding the field conditions of when you have valves close to the faucet, having no way to move the direction where you connect to the water supply lines. I'm concerned about what these lines will do years from now, under my liability. There's no "years" of product evaluation on those water lines.

@DUNBARPLUMBING They replaced the cartridge no questions asked. In fact calling the service line was quick and painless. I'd recommend them based on that. Thanks for the comment.

@kurtjthomas Although there have been fitting issues with PEX (almost always related to the "durable" brass parts), I have not run across anyone in the industry who has actually seen a PEX tube material fail due to the effects of pressure/temperature/chlorine in a plumbing application. Almost everyone has seen copper fail due to perforation from aggressive water conditions and enviromental effects (i.e. concrete contact).

@DUNBARPLUMBING

Actually, PEX has been tested under conditions well beyond the home plumbing system for at least 3 decades. The ASTM 876 and 877 standards, which these supply lines have been tested against, was developed based on scientifically determined life expectancy data using cummulative damage models, such as Miner's rule.

The reason we are going to the PEX is because the Govt. has stated that by 2010, they want all faucets to contain less than .025% lead/metal contaminant leaching into the water. From the time water hits the PEX lines until it comes out of the spout, it never comes into contact with any metal components. We still have metal where it matters though. In the faucet body, handle, bonnet nut and stainless steel stem.

If you find that the PEX lines are too long you have a couple options. You can bend them into a big loop to take up some of the excess. The other option (which we don't recommend) is to cut them. In the fauet box, there's extra ferrules if you decide to go this route.
