Frequently Asked Questions
Q. "How do the Delta seats and springs work?"
A. Delta's RP4993 seats and springs function quite simply, really. Not all Delta valves use them, but those that do have two inset holes within the valve (one for the hot water and one for the cold water), and that's where each seat and spring is placed. The spring goes into the hole first; it's wider on the bottom than it is at its top, and is inserted into the hole wide-end-first. The rubber seat is placed on top of the spring, like a cup. The spring presses the rubber cup against the bottom of either the control ball (the RP70 or the RP212) or the operating stem (RP1740), depending upon the type of faucet you have; the rubber cup creates a seal which prevents the water from flowing through (and out of) the faucet unless the faucet handle is used to position the control ball or cartridge in such a way to allow the water to exit.
Q. "What's the difference between the RP70 stainless steel ball and the RP212 stainless steel ball?"
A. Both the RP70 stainless steel control ball and the RP212 stainless steel control ball are used on certain single-handle Delta faucets, but on different types. The RP70 has a thin round post protruding from it and is used primarily with metal lever handles, allowing them to move in a circular pattern. The RP212 ball has a thicker, diamond-shaped post; it's used with some of Delta's acrylic round handles, and only allows them to turn left and right and/or move up and down.
Q. "Is it possible to identify the correct Delta handle or 'Hot'/'Cold' handle button based solely on measurements or description?"
A. Delta makes many different handles and buttons; some may appear similar or be of a similar size, but might not be interchangeable. Whenever you're in doubt about a manufacturer's part, especially when there are many options available, the actual manufacturer is always the best source to confirm appropriate parts.
