Buying Guide
What size should you choose? For most kitchens, a standard 1-1/2″ P-trap fits common drains. If you have restricted cabinet space, look for an expandable or flexible option like the FlexTRAP. Do you need a complete kit? If you’re replacing multiple components or upgrading fixtures, a 30-piece kit can save time and simplify purchases. Are materials important? Brass and PVC each have advantages; brass offers durability, while PVC can be easier to work with for quick DIY projects. Consider installation ease vs. long-term durability when selecting a model.
