What the AI looks for in Kitchen Sink Installation Parts
- Drain diameter
- Kitchen traps and tailpieces are 1-1/2 inch 1-1/4 inch is the bathroom size and will not fit or drain well.
- Mounting clips by install type
- Undermount sinks on stone use epoxy-anchored or drilled-insert clips; drop-in sinks use clips sized for the counter's thickness The wrong clip type can't carry the sink's weight or can crack the stone.
- Dishwasher connection
- Use a branch tailpiece or disposal inlet with a high loop or air gap where local code requires one These stop dirty sink water from flowing back into the dishwasher.
- Double-bowl drains
- Match the continuous waste kit to the type you need, either end outlet or center outlet The right layout keeps the drain level and lets everything fit under the sink.
- Supply connections
- Faucet supply lines are typically 3/8 inch compression at the shutoff valve; confirm the faucet-end thread Mismatched threads cause leaks or need extra adapters.
Brands that matter
- Oatey: Putty, traps and general installation supplies.
- Keeney: Traps, tailpieces and continuous waste kits.
- BrassCraft: Supply lines and shutoff valves.
- Dearborn: Tubular drain parts.
- Danco: Repair and replacement parts.
What to avoid
- Flexible corrugated drain pipe, which traps debris and isn't allowed by many plumbing codes
- Thin-wall tubular brass that has corroded, so replace it rather than reuse it
- Undermount sinks on laminate counters with no solid support
Questions
Plastic or metal P-trap?
Plastic traps are standard, don't corrode, and are easier to seal. Metal traps are mainly for looks where the plumbing is exposed.
