Introduction to Water Line and Valve Installation

Your kitchen appliances rely on more than power to run — they also need water. Refrigerators with dispensers and ice makers, dishwashers that run daily cycles, and even some specialty appliances all depend on dependable water lines and accessible shut off valves. If these connections are weak or outdated, they can cause costly leaks, water damage, and safety concerns.


Adept Installation provides professional water line and shut off valve installation in St. Louis and surrounding counties. With more than 40 years of combined experience, we know how to create connections that last. Whether you need a new line run to a refrigerator, a dishwasher valve replaced, or an entire kitchen plumbing adjustment during a remodel, we handle it all — and we leave the space finished, not patched together.

Why Professional Installation Matters

It’s easy to overlook water lines and valves until a problem occurs. Unfortunately, those problems can be expensive:



  • Hidden leaks can drip slowly inside cabinets for weeks before being noticed. By the time you see damage, wood may be warped and mold may have started to grow.
  • Old saddle valves — once common for refrigerators — are prone to failure. These outdated valves are not reliable for modern appliances.
  • Brittle tubing may crack without warning, releasing water across your floors.
  • Inaccessible shut offs can leave you scrambling during an emergency, unable to stop water quickly.


Professional installation solves these issues. At Adept Installation, we install modern shut off valves, replace outdated tubing, and route lines neatly with protective grommets. Every connection is pressure-tested so you know it’s safe before we leave.

Our Process

Step 1: Site evaluation

We inspect your plumbing, review appliance locations, and identify the best route for a reliable water connection.

Step 2: Planning the route

For new installations, we select efficient pathways — through cabinets, under floors, or behind drywall. Our goal is to keep lines discreet and accessible.

Step 3: Drilling and protection

We drill clean holes and install grommets to protect tubing from sharp cabinet edges.

Step 4: Installing or replacing valves

Outdated saddle valves are removed and replaced with modern quarter-turn shut off valves that provide a secure seal.

Step 5: Connecting appliances

Lines are connected to dishwashers or refrigerators using approved fittings and tested for stability.

Step 6: Testing connections

We pressure-test all connections under both static and running conditions to verify leak-free operation.

Step 7: Finishing and cleanup

Any cabinets or drywall disturbed during installation are patched, and packaging or debris is removed.

Common Situations We Handle

  • Refrigerator upgrades – Adding or relocating water lines for ice makers and dispensers.
  • Dishwasher replacements – Updating valves and lines when installing new dishwashers.
  • Kitchen remodels – Moving lines to match redesigned layouts.
  • First-time installations – Running new lines to spaces that never had water connections.
  • Emergency replacements – Quickly replacing failed valves or broken tubing to protect your home.

Why Replace Saddle Valves?

Saddle valves were a quick solution in older kitchens, but they were never intended for long-term reliability. They pierce pipes with a small hole, making them prone to clogging and leaks. Many manufacturers now require modern shut off valves for warranty compliance. Adept Installation replaces saddle valves with quarter-turn ball valves that are dependable, easy to use, and designed to last.
