New Sinks Mounted Right the First Time

Marble Falls Plumbing LLC installs kitchen sinks in Marble Falls with secure mounting, proper drain hookups, and code-compliant connections that last.

When you are replacing a kitchen sink in Marble Falls, whether during a countertop upgrade or because the old basin cracked, the new sink needs to be mounted securely, sealed against water intrusion, and connected to the drain and supply lines without leaks. Marble Falls Plumbing LLC handles the full installation process, from removing the old sink and cleaning the cabinet opening to setting the new basin, connecting the garbage disposal if present, and testing every joint under pressure to make sure nothing drips when the faucet runs or the dishwasher drains.


Sink installation includes attaching mounting clips or brackets depending on the sink type, applying a watertight seal around the rim, and connecting the tailpiece to the P-trap and drain arm that lead to the wall. If you are installing a deeper basin or switching from a single bowl to a double bowl, the drain height and trap assembly may need adjusting to maintain proper slope and prevent slow drainage. The work follows local plumbing codes to make sure venting, drainage, and supply connections meet current standards.

How a Kitchen Sink Gets Installed Properly

When you schedule a sink installation in Marble Falls, the plumber begins by disconnecting the old drain lines and supply hoses, loosening any mounting hardware, and lifting out the old basin. The countertop opening is cleaned, checked for damage, and prepped so the new sink sits flush and level. Undermount sinks are secured with epoxy and clips from below, while drop-in sinks are set into the opening and sealed with silicone around the top edge to keep water from seeping between the rim and the counter.


Once the sink is in place, you will see clean, even gaps around the perimeter with no lifting or shifting when pressure is applied. The drain connects tightly to the basket strainer, the P-trap is positioned with the correct downward slope, and the supply lines thread onto the faucet shanks without cross-threading or over-tightening.


Installation also includes reconnecting the garbage disposal if one is present, running water through the system to check for leaks, and making sure the drain flows freely without gurgling or backup. The work does not include replacing faucets, countertops, or cabinetry unless those are part of a separate scope, but it does ensure the sink is mounted securely and all connections function as intended for long-term use.

What Homeowners Usually Want to Know

Before scheduling a sink installation in Marble Falls, homeowners typically ask about compatibility with existing plumbing, how long the job takes, and what prep work is needed. These answers help set clear expectations and avoid surprises on install day.


  • What type of sink can be installed in my kitchen? The type depends on your countertop material and cabinet layout. Drop-in sinks work with most counters, while undermount sinks require solid surface or stone and additional support. Your plumber can confirm what fits your setup.
  • How long does a kitchen sink installation take? Most installations are completed in two to three hours, including removing the old sink, mounting the new one, and connecting the drain and supply lines. If the countertop needs cutting or the drain configuration changes, it may take longer.
  • Do I need to buy the sink before installation? Yes, you should have the sink on hand before the scheduled install so the plumber can confirm dimensions and mounting style. It also helps to have any included hardware, such as clips or strainer baskets, available during the visit.
  • Can a new sink be installed during a countertop replacement? Yes, sink installation works well with countertop upgrades in Marble Falls. The plumber coordinates with the countertop installer to make sure the sink is set and sealed properly once the new surface is in place.
  • What happens if the drain does not line up with the new sink? The plumber adjusts the trap assembly and drain arm to match the new sink depth and bowl position. This may include repositioning the P-trap or extending the tailpiece to maintain proper slope and prevent slow drainage.
