Watts 710332 – Frequently Asked Questions
1) Will the Watts 710332 no-hub reducer connect 4 inch pipe down to 3 inch?
That's exactly what it does. The Watts 710332 is a 4 x 3 inch reducer with no-hub ends, so it takes a 4 inch line down to 3 inch. Both ends are plain no-hub spigots, meaning you band them with standard no-hub couplings rather than solvent welding or threading.
2) What material is the Watts Blueline 710332 reducer made of, and where does that material belong?
It's FRPP, flame retardant polypropylene. That's the Blueline chemical drainage material, used for acid waste and lab waste lines where standard PVC or cast iron would be attacked. If you're plumbing ordinary sanitary DWV, this is not the fitting for that system.
3) Can I glue or thread this Watts FRPP reducer, or do I need mechanical couplings?
Mechanical only. The 710332 is a no-hub fitting, so each end is joined with a no-hub coupling and clamp band sized to the pipe (4 inch on one end, 3 inch on the other). There's no solvent cement joint and no thread on it, so order the couplings separately, they don't come with the fitting.
4) Will this Watts no-hub reducer mate to cast iron no-hub pipe?
Mixing materials in a chemical waste line isn't something to do casually. The 710332's ends are no-hub spigots in the 4 inch and 3 inch sizes, so the coupling geometry is the same family used on no-hub systems, but the reason you'd be running FRPP Blueline in the first place is corrosive waste that cast iron won't survive. Keep the acid waste run in FRPP and make any transition to cast iron outside the corrosive section.
5) What is the wall thickness on the Watts 710332 reducer?
0.24 inch. That's the fitting wall on the FRPP body, and it's the number to check against the pipe schedule you're running so the coupling gasket seats properly across the joint.
6) Is the 710332 a valve or a drainage fitting?
It's a fitting, not a valve. The 710332 is a reducer, a straight run of pipe that steps 4 inch down to 3 inch. Nothing in it opens, closes, or throttles flow.
