OATEY 704BN-1 – Frequently Asked Questions
1) Does the 704BN-1 P-trap come with brass slip nuts or plastic ones?
Brass nuts, with blue rubber washers that seal in brass applications. Brass nuts are what you want on a brass trap: they thread without the cross-threading and crushing you get mixing plastic nuts onto brass threads, and they can be snugged with a wrench. The Dearborn 704 family is also sold with plastic nuts, so confirm you are ordering the BN version if brass is what the spec calls for.
2) How long is the wall tube on the Dearborn 704BN-1 P-trap?
The wall tube measures 7-1/2 inches, which covers a typical lavatory rough-in where the waste arm sits close to the trap. If your drain stub-out is farther back than that, you will need a longer wall bend or an extension tube rather than this trap as-is.
3) Is the Oatey 704BN-1 a brass trap or plastic, and how thick is the wall?
It is 17 gauge brass with a chrome plated finish. That is the heavier of the two common brass gauges on lavatory traps, which is why it holds up in commercial restrooms and multi-family turnovers better than thin-wall tubular or PVC. Exposed under a pedestal or wall-hung sink, the chrome stays presentable.
4) Does the trap include an escutcheon or wall flange to cover the drain hole?
A shallow flange is included, so the opening around the wall tube is covered without a separate escutcheon purchase. Shallow means it hides a clean drywall or tile penetration; a badly oversized or chewed-out hole may still want a deep flange instead.
5) Should I use a slip joint brass P-trap or a glued PVC trap under a lavatory?
Slip joint is the choice when you want the trap to come apart. The 704BN-1 uses slip joint connections throughout, so you can break it down to clear a stoppage or retrieve a dropped ring and reassemble with the same washers. Glued PVC has to be cut out. For exposed installs the chrome brass also finishes the job, where PVC needs a cover or a cabinet to hide it.
6) What else do I need to order to finish a lavatory install with the 704BN-1?
The trap covers the P-bend, wall tube, brass nuts, washers and shallow flange. You still need a 1-1/2 inch trap adapter at the wall to receive the tube, and a tailpiece from the sink drain body down into the trap inlet if the existing one is too short or the wrong size.
7) What is the exact manufacturer part number for the Dearborn 1-1/2 inch brass-nut P-trap?
Oatey Dearborn 704BN-1. The BN in the number is the brass-nut designation and the trailing 1 identifies this configuration with the 7-1/2 inch wall tube and shallow flange. Order by 704BN-1 to avoid landing on the plastic-nut variant of the same 704 body.
8) How much does the Oatey 704BN-1 P-trap weigh?
About 1.318 lb. For an MRO buyer stocking a cart or a job box, that is useful when pulling a dozen at a time for a restroom retrofit, and it reflects the 17 gauge brass rather than tubular thin-wall.
