Kitchen Plumbing FAQs
Kitchen sink plumbing typically includes the sink drain assembly, the P-trap, the drain line connection, shut-off valves, supply lines to the faucet, and any connections for a dishwasher drain or disposal.
Slow drains are often caused by grease, food debris, or buildup in the kitchen sink drain plumbing. If the clog returns after basic cleaning, it may be deeper in the line.
Common causes include a loose P-trap connection, a leaking drain assembly, a failing shut-off valve, or a worn supply line. Under the kitchen sink, plumbing leaks can quickly damage cabinets, so it is best to address them early.
Yes. We repair leaks and clogs in double kitchen sink plumbing, including issues where one bowl backs up into the other or drains slowly due to shared drain connections.
Yes. We install dishwashers but do not service them. If the dishwasher has a mechanical problem, an appliance company is the right fit.
We do not recommend harsh chemical drain cleaners like Drano since they can cause more harm than good. Enzyme-based options like Green Gobbler are generally safer, and many clogs are best handled with professional diagnosis.
A kitchen sink plumbing diagram can help you understand the parts, but leaks are often caused by incorrect reassembly or worn seals. If the leak started after DIY work on the P-trap, a plumber can confirm that everything is connected correctly and watertight.
Kitchen Plumbing Services We Offer
Kitchen Sink Plumbing Repair
Kitchen sink plumbing issues are one of the most common calls we receive. If your sink is draining slowly, leaking underneath, or backing up, we diagnose the problem and fix it the right way.
We help with:
- Leaking kitchen sink drain connections
- Loose or damaged P-trap connections
- Clogged kitchen sink drain plumbing
- Water staining or moisture under the cabinet
- Worn shut-off valves under the sink
If you have tried a quick DIY fix and it is still leaking, it is usually best to have a plumber inspect the full under-kitchen-sink plumbing setup to prevent repeat issues. Call 603-424-8258 or visit our Contact Us page to book a visit.
Garbage Disposal Repair and Replacement
Garbage disposal failures and clogs are a top kitchen service call in New Hampshire. If the unit is jammed, humming, leaking, or smelling, our team can help.
Garbage disposal services include:
- Garbage disposal repair for jams and malfunctions
- Garbage disposal replacement when repair is not cost-effective
- Leak checks at the flange and drain connections
- Help diagnose odors caused by buildup
Homeowner tip: A safe way to clean the disposal is ice and dish soap, then flush with a sink full of water.
Kitchen Faucet Repair and Installation
A dripping faucet is annoying, but it can also waste water and signal internal wear. We repair when it makes sense, and replace when it is the better long-term solution.
Faucet services include:
- Kitchen faucet repair, such as cartridge replacement
- Kitchen faucet installation and upgrades
- Fixing low water pressure at the faucet
- Replacing failing shut-off valves
We recommend trusted brands like Kohler, Moen, and Delta because parts are easier to source and service. Supplier-grade fixtures are often built with higher-quality internal components than big box versions of the same model.
Dishwasher Installation
GSMS installs dishwashers but does not service or repair them. Appliance service is handled by appliance companies.
Dishwasher installation includes:
- Disconnecting the old dishwasher
- Connecting the new homeowner-supplied dishwasher
- Hooking up the water supply and drain line
- Testing connections for leaks
Helpful tip: Many dishwasher odor problems come from a dirty dishwasher filter. Cleaning it regularly can reduce smells and improve performance.
Refrigerator Ice Maker Lines and Supply Lines
Leaks from fridge lines and supply lines can be a major source of hidden water damage.
We inspect and replace:
- Refrigerator ice maker supply lines
- Faucet supply lines
- Dishwasher supply lines
- Old plastic lines that should be upgraded
We strongly recommend braided lines when appropriate. Braided supply lines should also be replaced periodically since they have a burst rating based on time and wear.
Double Kitchen Sink Plumbing and Drain Issues
A double kitchen sink plumbing setup often includes more connections and more opportunities for leaks. If one side backs up, drains slowly, or gurgles, the issue is often in the drain path or the connection between bowls.
We can help with:
- Double kitchen sink drain plumbing clogs
- Leaks at slip joints and drain assemblies
- Replacing worn drain parts under the sink
- Rebuilding incorrect connections from past DIY repairs
If you are dealing with repeated clogs, it usually means the problem is deeper than the P-trap and needs a professional diagnosis.
Repair vs Replace Guidance for Kitchen Plumbing
When you call GSMS for kitchen plumbing repair, we do not push replacement if a repair is the smarter option.
We recommend repair when:
- The issue is a replaceable part, like a faucet cartridge
- The fixture is in good condition, and parts are available
- The brand has reliable service support
We recommend replacement when:
- The fixture is older and showing finish wear or corrosion
- The brand has poor parts availability or unknown online sourcing
- The cost of repeat repairs is approaching replacement cost
Sometimes replacement is also a positive upgrade, since a new faucet can change the look and feel of the entire kitchen.
Home Club Membership for Kitchen Plumbing Checks and Priority Access
Home Club membership includes plumbing checks that cover kitchen fixtures, shut-off valves, supply lines, and fridge lines. This helps catch small issues before they become leaks.
Home Club checks can include:
- Inspecting shut-off valves and fixture connections
- Checking ice maker lines and braided supply lines
- Reviewing visible wear on supply lines and connections
Home Club members also receive priority access, including emergency service based on membership benefits. Call 603-424-8258 to ask about Home Club membership or visit our Contact Us page.
Reverse Osmosis Faucet Installations and Water Quality
A reverse osmosis faucet is typically installed at the kitchen sink, making kitchen plumbing a natural place to start if you are interested in better drinking water. If you are considering an RO faucet or system, we can review options and connect it properly during a kitchen faucet upgrade or sink plumbing service.
Call 603-424-8258 or visit our Contact Us page. You can also explore our water quality solutions page for more details.
