"What is the supercoat finish?"
Supercoat is a clear protective coating that eliminates the need to polish your brass hardware. Simply wipe clean with a soft cloth. Use of plumber's putty, detergents or abrasive cleansers may deteriorate the finish, otherwise it's guaranteed for 5 years from the date of purchase.

"If my washers fail, will the manufacturer replace them?"
No. The replacement of washers is considered to be normal wear and tear and must be done regularly to the protect the seat. Washer deterioation is directly related to use, water quality and overtightening of the handles. The handles need only be tightened enough to stop the flow of water. If, after the leftover water in the spout has drained, the faucets continues to drip, tighten slightly until the flow stops. This will increase the life of your washers dramatically. Replacement washers are something that will need to be purchased locally as the manufacturer will not ship them as replacements. When replacing washers, it is imperative that great care be taken when removing and replacing the bonnet nuts. A soft piece of cloth needs to be used to protect the finish of the nut, and the nut should never be overtightened. It will cause the nuts to eventually crack.

"Is there any special care for increasing the longevity of my shower hose?"
Yes. After each use, it is very important that all of the kinks be removed from the hose before setting the handset on the bracket. Kinks left in the hose or any unusual twisting or pulling will eventually cause the hose to crack, unravel and begin to leak.

"Why are some of these spouts and hoses not to code in some areas?"
If a spout terminates below the top of a tub (or a showerhead is able to reach below the top of the tub) then there is a chance (however small) that should the tub be filled to the top and the water valve is on (still running), the legally potable (drinking) water then is touching non-potable water. When that happens there is an extremely small chance (but it is possible and therefore not code in some areas) that the potable water can become contaminated. If this is a concern or applicable, then please order only code style faucets. Most portable showerheads will be able to be placed below the top of the tub and therefore most portable hoses (no matter what brand) are not to code as well.
We do offer an in-line 1/2" vacuum breaker for shower hose connections order #CLAW-S606ONDC chrome $27.98 or #CLAW-S606ONDB for polished brass $34.87 which some codes will allow for portable showerheads (but not all).
Again, some areas are very strict, and even with a vacuum breaker, where hoses could lay in water, some codes won't allow hoses at all. If your area has strict codes, then we do not recommend purchasing any shower hoses. We cannot be responsible, nor can we know what your area will or will not allow as far as code is concerned. Showerheads should not be laid down below the flood rim (not placed inside the tub) of a tub at any time.
