Old Plumbing Marietta: How It Impacts Water Pressure and Water Quality

Many homeowners in Marietta notice changes in water pressure or water quality without realizing that the real issue often sits inside their walls. Old plumbing affects how water moves through the home. Pipe walls weaken, rust forms, and minerals collect inside the lines, with rust and mineral deposits accumulating in old pipes. This buildup is restricting water flow and causing pressure issues. These conditions affect everyday use, from showers and faucets to drinking water and appliances. Addressing these issues early can prevent further damage to your home’s plumbing and structure. K L Contractor Plumbing Inc works with families across Marietta to identify these problems early and deliver long-term solutions that restore strong water pressure and clean water throughout the home.

Why Older Marietta Homes Experience Water Pressure Problems

Homes built before the 1990s used pipe materials for water pipes that break down faster than modern systems. Galvanized steel, early copper lines, and polybutylene were widely used during that time. As these pipes age, the interior surface becomes rough and narrow, and these issues are often present in older homes. This restricts water flow and causes water pressure to decline. Because this happens slowly, many homeowners ignore the early signs until the problem becomes severe.

Common causes of water pressure problems in old Marietta homes include corrosion, mineral buildup, and aging materials.

How Pipe Corrosion Reduces Water Flow and Pressure

Georgia’s water chemistry accelerates pipe corrosion. Minerals in the water attach to the inside of the line and harden over time, forming mineral deposits that make the pipe even narrower and restrict water flow. This mineral buildup makes the pipe even narrower, limiting how much water can pass through at once. Bacteria can also thrive in corroded pipes, contributing to water odor and accelerating further corrosion. Homeowners might notice:

• A shower that feels weaker than it used to

• A kitchen sink taking longer to fill, which is a sign of underlying pipe corrosion

• Water pressure dropping when multiple fixtures run at the same time

These changes rarely come from fixtures alone they usually point to corrosion inside the plumbing system.

Why Mineral Buildup Creates Low Water Pressure in Marietta

Hard water minerals bind to the inner surface of old piping. Over years, the buildup becomes thick enough to block water flow. As the blockage grows, pressure drops throughout the home. This can result in not having enough water for basic tasks like washing hands or brushing teeth. This can make normal tasks like running a dishwasher or washing machine take much longer. Many Marietta residents don’t realize how much buildup affects performance until the system is replaced.

How Old Pipes Affect Water Quality in Marietta Homes

Old plumbing doesn’t just affect pressure — it also changes water quality. As pipes corrode, rust breaks free and enters the water supply. Corroded pipes can also release lead into the water, affecting both safety and taste. This causes visible discoloration and changes in taste and smell, which can impact tap water quality. Some of the most common signs include:

• Brown or yellow water

• Rust flakes in the water

• A metallic or bitter taste

• Sediment settling in sinks, tubs, or toilets

• A rotten eggs smell, indicating bacterial growth or pipe corrosion

These symptoms show the plumbing system is deteriorating and may be nearing failure.

Signs Your Marietta Home Has Aging or Failing Plumbing

Homeowners should watch for:

• Frequent leaks

• Low or inconsistent water pressure

• Discolored or rusty water—a sure sign of plumbing problems

• Water stains on ceilings or walls

• Damp spots on walls or ceilings, which can indicate hidden leaks

• Water leaks, especially in older or corroded pipes

• Sudden spikes in water bills

• Unpleasant odors from taps

• Mold or dampness near plumbing lines

These signs indicate the system is aging and may need replacement rather than repeated repairs.

Brown or Yellow Water: What Rust and Sediment Reveal About Your Pipes

Brown or yellow water usually comes from oxidized metal inside old steel or iron pipes (often referred to as ‘brown water’). As corrosion spreads, flakes break off and mix with the water supply. This not only affects appearance and taste but can also clog fixtures, valves, and appliance components. Discolored water is one of the clearest indicators that the plumbing system has reached advanced deterioration.

Hidden Leaks and Structural Damage Caused by Old Plumbing

Corrosion thins pipe walls. Over time, pressure pushes through weakened areas, creating leaks behind walls, ceilings, and floors. Small leaks can go unnoticed but still cause significant damage over time, including water wastage, increased water bills, and low water pressure. These leaks often go unnoticed until:

• Wood framing swells

• Baseboards warp

• Ceilings sag

• Mold develops

• Mold growth occurs due to persistent moisture from leaks

By the time signs appear, water damage may be extensive. Early repiping prevents major repairs and protects the structure of the home.

Galvanized Steel, Copper, and Polybutylene: Common Old Pipe Materials in Marietta

Many Marietta homes include one or more of these aging materials:

Galvanized Steel

• Coating wears away

• Heavy rust formation

• Severe pressure loss

• Brown or orange water

Copper

• Pin-hole leaks

• Internal pitting

• Hidden moisture damage

Polybutylene

• Prone to sudden failure

• Fittings crack

• Often not accepted by insurance companies

All three materials show predictable patterns of deterioration and often require full replacement.

Why Repiping Restores Water Pressure and Water Quality Quickly

Repiping removes the failing lines and replaces them with modern materials that deliver: pipe replacement is a key solution for old plumbing, ensuring long-term reliability and preventing issues caused by corroded or aging pipes.

• Strong, consistent water pressure

• Clean, clear drinking water

• Faster appliance cycles

• Better performance from water heaters

• Fewer future repairs and leaks

• Reduced need for pipe repair and ongoing repair costs

Most homeowners notice the improvement immediately after installation.

PEX vs Copper: Best Repiping Choices for Marietta Homeowners

PEX Piping

• Flexible and durable

• Resists corrosion

• No mineral buildup

• Performs well with Georgia’s water chemistry

Copper Piping

• Strong and long-lasting

• Excellent for high-heat systems

• Reliable for decades when installed correctly

K L Contractor Plumbing Inc installs both options and helps homeowners choose the best fit for their home and long-term goals.

When It’s Time to Consider Repiping Your Entire Home

You should consider a full home repipe if your home shows:

• Low water pressure throughout the house

• Repeated pipe leaks

• Brown or yellow water

• Outdated materials such as galvanized or polybutylene

• Rising water bills

• Noticeable corrosion on exposed pipes

Homes built between the 1970s and early 1990s are at the highest risk and often benefit from a professional inspection. For the best results and to address all your plumbing needs, consult a professional plumber or plumber to assess your system and recommend the right solution.

Financial Benefits of Replacing Old Plumbing Before Problems Spread

Aging plumbing creates ongoing costs:

• Repeated leak repairs

• Rising water bills

• Undetected leaks often leads to higher costs over time, as small leaks from corroding pipes can go unnoticed and increase your water bill

• Appliance failures

• Higher energy use from inefficient flow

• Mold removal and structural repairs

Repiping eliminates these recurring expenses and prevents emergency breakdowns. A new piping system is a one-time investment that provides decades of reliability.

How Repiping Increases Property Value in Marietta

Buyers look for homes with strong, safe, modern plumbing systems. A repiped home:

• Sells faster
