Kitchen Plumbing

The kitchen is where grease, food and water meet — along with a dishwasher, a fridge line and often a gas range. We clear and repair kitchen drains, hook up appliances properly, and plumb renovations from the stack to the faucet.

At your location in 60 minutes or you save $60.

The short answer

If the kitchen sink is backing up, stop running water and the dishwasher, and don’t pour drain cleaner into standing water. If a dishwasher or fridge line is leaking, close its valve under the sink or behind the fridge. If you smell gas, get everyone out, don’t touch switches or flames, and call 911 or the gas utility from outside. Then call us — we’re at your location in 60 minutes or you save $60, and you get the price before we start.

Is this an emergency?

  • You smell gas — get out first, then call 911 or the gas utility from outside

Not sure? Call anyway — we’ll tell you honestly.

Do this right now

  1. Stop running water and the dishwasher until the sink drains.
  2. If a dishwasher or fridge line is leaking, close its valve — usually under the sink or behind the fridge.
  3. If you smell gas, get everyone out, don’t touch switches or flames, and call 911 or the gas utility from outside.
  4. If water you didn’t run is coming up in your sink, tell your super — the shared line is blocked.

Signs you need us

  • Water standing in the sink long after the dishes are done
  • Dishwater rising in the sink when the dishwasher pumps out
  • Dirty water left in the bottom of the dishwasher
  • Your sink backs up when the neighbors above run water
  • Water under the fridge, or an ice maker that has stopped
  • A swollen toe-kick or warped floor in front of the dishwasher
  • Drips from the trap or drain joints under the sink
  • A smell of gas near the range

How we handle the call

  1. 01

    Find the blockage

    We work out whether the clog is in your trap, your branch line or the building’s kitchen stack — that decides the tool, and whether your super needs to know.

  2. 02

    Clear grease properly

    In a kitchen line, grease coats the whole pipe, so we cable it open and, where the buildup is heavy, jet it clean so it stays clear longer.

  3. 03

    Fix the hookups

    Dishwasher drain loop or air gap, supply valves and the fridge line — set up so water drains and fills the way it should.

  4. 04

    Safe gas connections

    A range goes in with a new flexible connector and a shut-off valve you can reach, and every joint is tested for leaks.

  5. 05

    Plan the new layout

    For a renovation, we route the drain, vent and supply lines, check them against the building’s rules and test everything before the cabinets go in.

Know your building

Kitchen stacks and renovations in apartments and houses

In most apartment buildings, kitchens are stacked, and every sink in the line drains into one shared kitchen stack. Decades of grease narrow that pipe, and when it finally blocks, water from the floors above comes up in the first sink below the clog — usually on a lower floor. If dishwater you didn’t run is rising in your sink, it’s a building problem: tell your super or building manager, and stop using your sink until the stack is cleared. Restaurant kitchens deal with the same grease on a bigger scale, which is why food businesses are generally required to have a grease trap or interceptor — and one that isn’t cleaned out regularly stops doing its job.

Kitchen renovations in co-ops and condos run on the building’s rules: an alteration agreement, limited work hours and, in many co-ops, limits on moving a kitchen over a neighbor’s living space. Even within the same footprint, moving a sink to an island means running a drain and vent under the floor, which can mean working in the ceiling of the apartment below. Older rowhouses, townhouses and detached houses usually give you more freedom, and a basement or crawlspace underneath makes an island drain much easier to run. In an older house, though, a galvanized kitchen line is often due for replacement while the walls are open.

Upfront price, every time

What kitchen plumbing costs

A clog in the trap or a leaking drain joint is a short job. A blockage deep in the line, or grease that needs jetting, takes longer — and a blockage in the shared stack is normally the building’s to clear, so owners and managers call us for that.

Hookups are priced by what’s already there: connecting a dishwasher or fridge to existing valves is simple, while running new lines, adding a pot filler or moving a sink means opening walls or floors. You get the price before we start, and for a renovation, a written scope you can share with your building.

Honest advice

Keep the plumbing, or replumb the kitchen?

If you’re keeping the layout, most kitchen problems come down to a part: a trap, a valve, a hose, a faucet. Fix that, and the kitchen works — there’s no need to open walls for a clog or a leaking connection.

If the cabinets are coming out anyway, that’s the cheapest moment you’ll get to replace old galvanized supply and drain pipe back to the riser and stack, add proper shut-offs for the dishwasher and fridge, and rough in a pot filler or filter faucet. Do it then, and the new kitchen isn’t sitting on decades-old pipe.

Mistakes that make it worse

  • Running the dishwasher drain hose straight down with no high loop — dirty sink water can flow back in
  • Tapping a fridge line with a saddle valve — they’re a common source of slow leaks
  • Shoving the fridge back against the wall and kinking its water line
  • Hooking up a gas range yourself, or reusing the old connector when it’s replaced

Keep it from happening again

  • Scrape plates into the trash before rinsing — food and fat are what narrow a kitchen line
  • Clean the dishwasher’s filter often so scraps don’t end up in the drain hose
  • Leave slack in the fridge water line so the fridge can be pulled out without kinking it
  • Keep your carbon monoxide alarm working — many states and cities require them in homes

FAQ

Kitchen Plumbing questions

Why does water come up in my sink when my neighbors run theirs?

Your sink shares a kitchen stack with the apartments above, and it’s blocked below your connection. Stop using your sink and tell your super — clearing the stack is a building job, and we do it for owners and managers.

Does my dishwasher need an air gap?

It needs either an air gap on the counter or a high loop — the drain hose fastened up under the counter before it connects to the sink drain or disposal. Either one stops dirty sink water from siphoning back into the dishwasher.

Can you hook up a gas range?

Yes — with a new flexible connector, a working shut-off and a leak test on every joint. Gas leaks, new gas piping and service shut off by the utility are covered on our Gas Line Repair page.

Can you install a pot filler?

Yes. It needs a cold-water line run inside the wall behind the range, so it’s easiest during a renovation; most have one valve at the wall and another at the spout, so the arm can be shut off completely when it’s folded away.

Can my kitchen sink move to an island?

Usually, yes — the drain and vent run under the floor to the island. In an apartment building that can mean working in the ceiling below, and co-op rules may limit it, so we check before you commit.

My ice maker stopped and there’s water under the fridge. What happened?

Usually the water line has cracked, kinked or come loose behind the fridge, or an old saddle valve has started to leak. Close the valve that feeds it, and we’ll replace the line and valve properly.
