Buying Guide
What size do I need? Most sinks use 1-1/2″ or 1-1/4″ drain fittings. Check the inlet and outlet measurements on your current setup to choose a compatible P-trap kit.
Is brass better than plastic? Brass P-traps offer durability and corrosion resistance, while some plastic options provide flexibility and lower cost. Choose based on budget, space, and expected wear.
Do I need expandable or fixed length? Expandable or flexible tubes are advantageous in tight cabinets or unusual layouts. Fixed-length kits are simpler and reliable when alignment is straightforward.
Is a clean-out feature important? A clean-out makes removing clogs easier without dismantling the entire trap. It’s a practical feature for busy kitchens and bathrooms.
What about double sinks? Double-bowl configurations may benefit from adjustable-height or end-outlet kits and flexible tailpieces to align drains with the wall connections.
