Watts NH-PLENUM+-1.5-45E – Frequently Asked Questions
1) What size and connection does the Watts NH-PLENUM+ 45 degree elbow use?
It's a 1.5 inch no-hub (hubless) fitting, so it joins to cast iron or plastic no-hub pipe with standard no-hub couplings and clamps rather than being solvent welded or threaded. The model number is NH-PLENUM+-1.5-45E.
2) Is the Watts NH-PLENUM+ elbow Buy American Act compliant for a government job?
No. The NH-PLENUM+-1.5-45E is listed as not Buy American Act compliant, so it will not satisfy a BAA procurement clause on a federal or federally funded project.
3) Will the NH-PLENUM+ 1.5 inch elbow fit standard cast iron no-hub pipe?
Yes, as long as the pipe is 1.5 inch no-hub. No-hub fittings and pipe are dimensioned to a common outside diameter per size, so a 1.5 inch no-hub coupling will clamp the elbow to 1.5 inch no-hub cast iron. It will not mate to hub-and-spigot or threaded pipe without an adapter.
4) Do I need couplings to install the 1.5 inch no-hub 45 elbow, or are they included?
The NH-PLENUM+-1.5-45E ships as the fitting only. No-hub connections are made with separate shielded couplings sized for 1.5 inch pipe, so order a coupling for each end of the elbow along with the fitting.
5) When do I use a 45 degree elbow instead of a 90 on a drain line?
A 45 keeps the flow sweeping and is what most plumbing codes want on horizontal drainage offsets and at the base of stacks, where two 45s give a gentler turn than a single hard 90. Use the 90 where you're turning up into a vertical or tying into a fixture drop. The Watts NH-PLENUM+-1.5-45E covers the 45 degree turn on 1.5 inch no-hub pipe, the size typically used for lavatory and similar small fixture drains.
6) Can I get the full dimensional data for the Watts NH-PLENUM+-1.5-45E?
Watts publishes a spec sheet for the NH-PLENUM+-1.5-45E, and it's linked from the product information. That sheet carries the fitting's laying length and other dimensional detail for layout work.
