Watts NH-BL-2-45E – Frequently Asked Questions
1) What size and angle is the Watts NH-BL-2-45E no-hub elbow?
It's a 2 inch, 45 degree elbow in the Watts Blueline no-hub line. The 45 degree sweep is what you use for offsets and for turning a branch into a run at a gentler angle than a quarter bend, which keeps drainage flow better than a hard 90.
2) Does the NH-BL-2-45E elbow need no-hub couplings, or does it come with them?
The fitting is hubless on both ends, so it joins with no-hub couplings (a gasketed sleeve and shielded clamp band) sized for 2 inch. Those couplings are ordered separately, along with any adapters if you're tying into hubbed or threaded pipe.
3) Is the Watts NH-BL-2-45E Buy American Act compliant for a government job?
No. The NH-BL-2-45E is not Buy American Act compliant, so it won't satisfy a federal or BAA-flowdown spec. If the project carries that requirement, source a domestically produced no-hub 45 instead.
4) Will a 2 inch no-hub 45 fit standard 2 inch DWV pipe?
It mates with 2 inch hubless pipe and fittings of the same no-hub outside diameter, which is the standard for hubless DWV systems. If your existing line is 2 inch PVC or cast iron hub-and-spigot, you'll need a transition coupling or adapter to make the joint.
5) What part number do I order for a Watts Blueline 2 inch 45 degree no-hub elbow?
Order Watts part number NH-BL-2-45E. That's the single model in the Blueline no-hub range covering the 2 inch 45 degree bend.
6) Should I use a 45 degree elbow or a 90 for a drain offset?
For a drainage offset, two 45s give a long sweep that resists solids hanging up and is easier to rod out than a hard quarter bend. Use a 90 only where the space forces it or where the code detail calls for a sanitary or long-turn quarter bend. The NH-BL-2-45E covers the 2 inch 45 in a hubless system.
