Whole Home Plumbing Inspection Services on Long Island, NY

Most homeowners think about their plumbing only when something goes wrong. Usually, we get a call for an inspection because someone is buying or selling a house, or they’ve just moved into one of Long Island’s older homes and want to know what they’re dealing with. At T.F. O’Brien, we’ve been helping Nassau and Suffolk County neighbors stay comfortable since 1934. We’re bringing that same honest, professional approach to your home’s plumbing. If you want to stop a problem before it starts, call us to schedule an inspection.

What Is a Whole Home Plumbing Inspection?

A whole-home plumbing inspection is a top-to-bottom look at your entire system. Instead of just fixing a single leaky faucet, a licensed plumber walks through your house to check every pipe, valve, and connection we can get to. Think of it as a wellness check for your home. Our goal is to give you a clear report on how things look; we aren’t there to pressure you into immediate repairs. It’s a much deeper look than you’d get from a standard home inspector, who usually only checks the basics.

What We Check During a Plumbing Inspection

When we visit your home, we follow a simple, room-by-room process. We look for the small warning signs that most people miss, from a bit of corrosion on a valve to a toilet that isn't sitting quite right.

Water Lines and Shut-Off Valves

We check your main water shut-off and the smaller valves under your sinks to make sure they actually turn when you need them to. Many homes in Nassau and Suffolk were built decades ago and might still have old piping materials that are prone to rusting or leaking.

Sinks, Toilets, and Showers

We check every fixture for leaks, steady water pressure, and signs of wear. We pay close attention to toilets to make sure they aren't "ghost flushing" (wasting water) or rocking, which can damage the floor underneath. We also check shower drains and the seals around your tub to keep water from seeping into your walls.

Your Water Heater

We take a look at your water heater’s connections and the overall condition of the tank. We’re looking for signs of rust or buildup that could mean your heater is getting close to the end of its life. If we see something concerning, we can talk you through your options.

Drains and Exposed Pipes

We check the visible drain lines under your sinks and in your basement for slow drainage or signs of a clog. We also look for "mystery stains" on your ceilings or floors that might point to a hidden leak. This inspection is focused on the plumbing inside your home, rather than the main sewer line outside.

Outside Faucets

Long Island winters can be tough on outdoor plumbing. We check your outside spigots to make sure they haven't been damaged by a freeze and that they shut off completely.

When a Plumbing Inspection Makes Sense

It’s about being proactive. Here are a few times when a professional look is a smart move:

  • Buying or Selling: A general home inspection is okay, but a licensed plumber can give you the real story before you close the deal.
  • Owning an Older Home: If your house was built between the 1950s and 1980s, an inspection helps you understand what needs attention first.
  • Peace of Mind: If your water bill is creeping up or you’ve had a major leak recently, an inspection ensures there aren't other hidden issues waiting to pop up.
