Kitchen Pipework & Layout
Kitchen plumbing fails at the connections, not the cabinets. The sink move, the island vent, the dishwasher pairing, and the gas run are the decisions that decide whether the finished kitchen stays dry. Go back to our Spring Hill homepage for the full service list, or stay here for the kitchen side.
Direct answer: the kitchen test that matters is the before-counters test: every supply, drain, and shutoff tested with the cabinets still open, so the first leak is found on an open wall, not under new cabinets.
The Sink Move and the Island Problem
Kitchen sink relocation plumbing is the biggest scope decision in most kitchen projects. A sink that moves a few feet along the same wall is a short job. A sink that moves to an island is a venting job: the island needs a venting plan, not just a longer drain, and the drain must hold slope to the stack. A long flat run or a vent with no path can rule out a move, which is why the sink location is decided before cabinets are ordered.
The cabinet sink base deserves a look too. A sink base that hides a slow drip will rot before anyone notices, so we test every connection in the open cabinet and check the shutoffs while they are still reachable. Shutoffs go within reach, labeled, and in front of the finished wall: sink shutoffs in the cabinet, a dishwasher shutoff you can reach without pulling the appliance, and a gas shutoff at the range.

Dishwasher and Disposal Pairing
Disposal plus dishwasher pairing and drain configuration cause post-remodel backups when the high loop or air gap is missed. The dishwasher drains through the disposal inlet when a disposal is fitted, and a new disposal ships with that inlet plug in place. If the plug is not knocked out, the dishwasher cannot drain at all. The drain hose must climb to a high loop or an air gap before it falls, or sink water will back up into the dishwasher tub.
The pairing also decides the waste line layout under the sink. A disposal, a dishwasher connection, and a sink waste line in one cabinet need room and a clear route, or the cabinet becomes a tangle that nobody can service. We lay out the cabinet connections before the sink goes in, so every joint stays reachable.

Gas Range, Pot Filler, and Fridge Lines
A gas line for kitchen range moves needs sizing, a shutoff, and an inspection. A range that moves across the kitchen usually needs a new run, and the line must be sized from the appliance rating, not from the old pipe. The shutoff goes at the range, within reach, and the line is pressure-tested before the range is pushed back.
Pot-filler, fridge ice-maker, and bar-sink additions are the small extras that add supply and drain runs owners underestimate. A pot filler needs a supply run inside the wall. A fridge line needs a route from the nearest cold supply. Both are small jobs during a remodel and awkward retrofits after the tile is up. If you want either, add it now.

Filtration Tie-Ins and the Before-Counters Test
Hard-water and filtration tie-ins, softener lines, reverse-osmosis units, and fridge filters, are often decided late and then retrofitted awkwardly. A softener or filtration line that is planned into the remodel gets a clean route and a shutoff. One added after the cabinets go in gets whatever route is left. EPA WaterSense guidance covers water-efficient fixtures worth considering while the kitchen is open.
The before-counters test plan is the last step before the kitchen is closed up: every supply pressurized, every drain run, every shutoff closed and opened, and every joint checked dry. If a connection weeps, it gets fixed while the wall is still open. A kitchen that passes that test is a kitchen that stays dry.

Kitchen Remodel Questions
Usually yes, if the drain can hold slope to the stack and the island can be vented properly. An island sink needs a venting plan, not just a longer drain, and that plan is decided before cabinets are ordered.
It depends on where the range sits and whether the existing line can carry the load. A range that moves across the kitchen usually needs a new run, a shutoff, and an inspection. We size the line from the appliance rating, not from the old pipe.
Gurgling usually means venting or slope trouble: the drain is pulling air through a trap instead of through a vent. Island sinks and long runs are the usual suspects, and the fix is in the venting, not in the disposal.
Within reach, labeled, and in front of the finished wall: sink shutoffs in the cabinet, a dishwasher shutoff you can reach without pulling the appliance, and a gas shutoff at the range. A shutoff hidden behind a fixed panel is a shutoff you will not find in a hurry.
If you want either, add it now. A pot filler needs a supply run inside the wall, and a fridge line needs a route from the nearest cold supply. Both are small jobs during a remodel and awkward retrofits after the tile is up.
