Galvanized Pipes in Your Mar Vista Home: What a Buyer's Inspector Will Say Before You Sell

Galvanized pipes do not stop a Mar Vista home from selling. They do change the conversation. A buyer's inspector will spot them, write them up, and usually recommend a licensed plumber evaluate the system. From that point on, the pipes are part of the negotiation whether you planned for them or not.

You have three workable paths: replace them before you list, disclose them and price the home with them in mind, or disclose them and be ready to negotiate a credit. Each one can be the right call. The wrong call is finding out what you have in the middle of escrow.

Galvanized pipe is steel pipe coated in zinc to slow rust. For decades it was a standard material for the water supply lines that carry fresh water from the street to your faucets, tub, and water heater. Over time builders moved to copper, and today most new work uses copper or PEX, a flexible plastic tubing.

Much of Mar Vista is original mid-century housing, built during the years when galvanized supply lines were common. Plenty of those homes have been updated over the decades, but updated is rarely all at once. It is common to find a kitchen remodel with new copper under the sink, a newer water heater, and original galvanized pipe still running through the walls and under the house.

The problem with galvanized pipe is that it ages from the inside. As the zinc coating wears, the steel underneath corrodes and mineral deposits build up on the interior walls. The opening narrows. Water pressure drops, sometimes so slowly that the people living in the house never notice. Joints and threaded connections are where leaks tend to start.

You can get a good first read in about ten minutes, before any inspector arrives.

• Find the pipe where water enters the house and at the water heater. Those are usually the easiest places to see the original supply lines.
• Look at the color. Galvanized pipe is dull gray or silver. Copper is reddish brown. PEX is plastic, often red, blue, or white.
• Try a magnet. A strong magnet sticks to steel. It will not stick to copper or plastic.
• Scratch it lightly with a key. Galvanized shows a silvery gray underneath. Copper shows a bright penny color.
• Check the threads. Galvanized pipe is joined with threaded fittings. Copper is usually soldered with smooth joints.

Then notice the symptoms. Low pressure at one or two fixtures, rust-tinged water when a tap has not been used for a while, or a history of pinhole leaks all point the same direction. If you have had a plumber out for any of these, find the invoice. It will matter later.

A general home inspector looks at what is visible and tests what can be tested without opening walls. With galvanized pipe, that usually means checking water pressure and flow, looking for corrosion and old leaks at visible sections, and noting whether the system is a mix of materials. The report will typically say galvanized supply lines are present, that they are near or past the end of their expected life, and that a licensed plumber should evaluate them.

That sentence is what the buyer reads at night. From there, the questions are predictable.

• Is all of the supply plumbing galvanized, or only part of it?
• Has any of it been replaced, and was that work permitted?
• Have there been leaks, and were they repaired?
• What would a full repipe cost?

The buyer may also be shopping for homeowners insurance during escrow. Some insurers ask about the age and type of plumbing when they write a new policy, and an older system can affect the answer or the price. That is one more reason the buyer will want clarity, and one more reason it helps to have answers ready. I covered the broader insurance picture in this guide to homeowners insurance for Westside buyers and sellers.

A partial repipe is common in older Mar Vista homes, and it is worth a closer look. When copper is connected directly to galvanized steel, the two metals react with each other and the joint can corrode faster than either pipe would on its own. The fix is a fitting called a dielectric union, which separates the two metals. A plumber can tell you quickly whether the transitions in your home were done that way.

Partial work is not a problem in itself. It just needs to be described accurately. "Kitchen and water heater connections replaced with copper in 2015, remainder original galvanized" is a clear, useful sentence for a buyer. "Plumbing updated" is not, because a buyer's inspector will find the original pipe and wonder what else the description left out.

Repipe before listing. Replacing the supply lines removes the issue from the inspection report and from the negotiation. It also means opening walls or ceilings in spots, patching and painting afterward, and living through the work. In the City of Los Angeles, which includes Mar Vista, repiping is permitted work through the Department of Building and Safety. Get the permit, keep the final sign-off, and put both in your disclosure package. Unpermitted plumbing work creates its own questions, which I walk through in this article on unpermitted work.

Disclose and price it in. Many buyers of original mid-century homes expect some updating. If the pipes are galvanized and you know it, say so, get a plumber's estimate in hand, and set the price with the condition in mind. A buyer who reads about the pipes in your disclosures before writing an offer has far less room to renegotiate after the inspection.

Disclose and negotiate a credit. Some sellers prefer not to take on a project before moving. A credit toward the buyer's closing costs, or a price adjustment, lets the buyer handle the repipe after closing with their own plumber. A written estimate from a licensed plumber keeps that conversation grounded in a real number rather than a guess. The guide to negotiating repair requests covers how those requests usually work.

Which path fits depends on your budget, your timeline, whether you are still living in the home, and how the rest of the house shows. That is a conversation I have with every seller of an older home, before anything goes on the market.

California's Transfer Disclosure Statement asks sellers about defects or malfunctions in the home's systems, including plumbing. If you know you have galvanized pipe, low pressure, past leaks, or a partial repipe, it belongs on the form, along with any repair invoices and permits you have. Write what you know, in plain words, and nothing you are guessing about.

If you are not sure what is in the walls, it is fine to say so and let the buyer's side investigate. What causes trouble is a confident description that turns out to be wrong. The guide to California seller disclosures walks through the whole package, and the Mar Vista termite report article covers another inspection most older homes will see.

If your Mar Vista home is original or partly original, here is the short list before you list:

• Check the pipe at the water heater and where water enters the house.
• Gather any plumbing invoices, permits, and the dates of past repairs.
• Have a licensed plumber evaluate the supply lines and give you a written estimate.
• Decide, with real numbers in hand, whether to repipe, price it in, or plan for a credit.
• Describe the system accurately on your disclosures.

I handle this as part of preparing every listing. I bring in the plumber, review the estimate with you, and help you choose the path that fits your plans, so the pipes are a known item and not a surprise. If you are thinking about selling in Mar Vista and the shower pressure has been a little weak for years, get in touch. No pressure, just real answers.
