OATEY 814ETBN-1 – Frequently Asked Questions

1) What is the branch on the Oatey Dearborn 814ETBN-1 tailpiece for?
The 7/8 inch branch on the 814ETBN-1 is a hose and clamp connection, used to take a discharge line (typically a dishwasher or similar appliance drain hose) into the sink tailpiece above the trap. The branch sits 3 inches from the center, so you get room under the sink basket before the hose connection.
2) Will this Dearborn branch tailpiece connect to a standard 1-1/2 inch sink drain and P-trap?
Yes. The 814ETBN-1 is a 1-1/2 inch by 8 inch tailpiece with a slip joint top and a brass slip nut, so it threads to a standard 1-1/2 inch sink strainer or basket and drops into a 1-1/2 inch slip joint trap below. Slip joint is the connection type throughout, so no soldering or threading is needed.
3) What does nut down mean on the 814ETBN-1 tailpiece?
Nut down means the brass slip nut rides on the tailpiece with the threads facing downward, so the tube is captured by the nut at the top connection rather than being threaded itself. Order the nut-down version when the fitting it lands on is male-threaded and the nut has to pull up onto it.
4) Is the Oatey 814ETBN-1 brass or plastic, and what gauge is the tube?
It is brass tubing in 20 gauge with a chrome finish and a brass slip nut. Twenty gauge is the heavier wall you want in commercial and multi-family work where the trap gets taken apart repeatedly, versus thin-wall or plastic tubular drain parts.
5) Can I cut this 8 inch branch tailpiece down to fit a shallow sink cabinet?
Yes. The 8 inch length is a brass tube with the slip nut at the top, so you cut from the bottom end and it still seats in the trap slip joint. Keep the 3 inch branch-to-center dimension in mind when you plan the cut, since the hose branch has to clear the bottom of the sink basket.
6) Do I need a separate dishwasher wye or air gap if I use this branch tailpiece?
The branch is built into the tube, so you do not need a separate tee or wye in the drain line. You still need the hose clamp connection made at the 7/8 inch branch, and whether an air gap is required is a local code call, not a function of the fitting.
7) Does the 814ETBN-1 come in a finish other than chrome?
The Dearborn branch tailpiece family is offered in chrome or rough brass. The 814ETBN-1 itself is the chrome version, which is the one to use on an exposed sink installation where the tailpiece is visible.
8) How heavy is the Oatey 814ETBN-1 for freight or stocking purposes?
The 814ETBN-1 weighs 0.62 lb with a volume of 0.072, which makes it easy to carry a few on the truck as standard under-sink service stock.
