Buying Guide: Key Considerations for 3/4 Urinal Spuds
What size fits my urinal? Most 3/4 inch spuds pair with standard urinal drain connections but always measure your existing pipe and thread size before purchasing. Consider whether you need a single replacement or a multi-pack for ongoing maintenance.
What material matters? Brass spuds offer durability and better sealing in humid restrooms; avoid cheap alloys that may corrode quickly in damp environments. Corrosion resistance is especially important in commercial facilities with high turnover.
Is hardware included? Kits that come with locknuts, washers, and gaskets simplify installation and reduce the number of separate parts you must source. Confirm that the included hardware matches your urinal’s mounting requirements.
What about compatibility? Some spuds are made for specific brands (EZ-FLO, Sloan). Verify compatibility with your urinal model and flushometer if applicable. When in doubt, choose a universal-fit option or contact the manufacturer for guidance.
How many spares should I stock? For high-traffic restrooms, a multi-pack or a kit with extra washers and nuts helps prevent downtime during repairs. For smaller facilities, a single sturdy spud with a complete kit may suffice.
