Repipe Services

A repipe is a complete replacement of the water lines inside your home.  The most common reason for a repipe in the greater Seattle area is to replace old galvanized lines with copper or PEX. This helps ensure your water lines are free of lead, corrosion and leaks. A repipe may also increase the water volume in your home, depending on your Seattle neighborhood’s water pressure.

  • Galvanized iron pipes, also called galvanized pipes, are actually steel pipes coated with a layer of zinc. The zinc was added to extend the life of the pipe but it contained lead and other metals. These pipes were commonly installed in homes built in Seattle before the 1960’s. 
  • Corrosion and lead are the main concerns with galvanized pipes. Lead can also be found in the connections to the city’s lead pipes in the street.
  • As pipes corrode over time, rust debris forms and reduces the diameter of the pipe.  This can reduce the water flow to your fixtures, and can create water quality issues.  In addition, the corrosion can cause galvanized pipes to leak and can cause water damage to your property.

Test your pipes to see if they are galvanized by placing a magnet on a bit of exposed pipe in your home.  A magnet will stick to galvanized pipe. Magnets won’t stick to copper or plastic pipes.


Some homes have a partial replacement of galvanized pipes in the kitchen area, especially if a kitchen was remodeled. Instead of a partial replacement, Raymark recommends a full replacement of the home’s pipes. This is because the shaking and vibration caused by cutting and moving galvanized pipes can loosen the accumulated corrosion. This debris clogs sink aerators, shower heads, faucets, and cartridges.

The vibration can also disturb corroded pipes in interior walls and potentially cause a leak. Due to this potential loosening, we can’t guarantee the outcome when a partial replacement is done. It is also more cost effective to replace all water lines at one time. For these reasons,  a partial repipe is not recommended.

Also, the installation of new faucets and valves can inadvertently cause pipe damage and leaks. Therefore, we recommend replacing old galvanized lines before installing new faucets. 

If you are looking for a partial replacement due to a better quality of water, a water filter may be a better solution. Please see our Water Filter page for more information.


Your water supply lines bring in fresh water. These older water lines weren’t built to last forever. A replacement of your home’s fresh water supply lines ensures cleaner water and sturdy, dependable pipes.  A repipe should last the life of your home.

Repipe Services FAQs

  • What is a repipe?

    A repipe is the complete replacement of all the water lines inside your home. Homeowners usually replace old galvanized lines with PEX or copper. As a result, they improve water quality and have less risk of corrosion and leaks.

  • What kind of pipes do I get when I do a repipe?

    Copper or PEX pipes are recommended by Raymark. PEX is Cross Linked Polyethylene water tubing. It has proven to be resilient, reliable, and not prone to leaks. Copper is the hardiest option but is more costly due to the price of copper and the additional time needed.

  • I have some galvanized and some copper lines. Is having both a problem?

    Galvanized and copper metals must have brass between them to prevent electrolysis.  Electrolysis is a chemical reaction between two incompatible metals. When dissimilar metals make contact, a pinhole leak occurs at the point of contact or down the line and it will expand over time. Therefore, we recommend your lines are the same metal or that preventions are put in place.

Called on a holiday morning with a toilet crisis (it WAS a crisis because we only have one, and it was completely clogged) – Joe promptly came out and remedied the situation within the hour. Expected a long wait and a hefty bill but no such case. Joe additionally advised us to replace our old, inefficient toilet sometime in the future. Not the first time we’ve called Raymark and won’t be the last.

Jose was awesome: gave my kitchen faucet a quick temporary fix while I got a new fixture, and then installed the new one perfectly. Brittany (in the office) made sure Jose got here as soon as possible!

Hayden and his team were fantastic. Fast, high-quality work at an affordable price. They have a lot of experience dealing with older buildings, and I would highly recommend Raymark for anyone living in a building or home with older pipes.

Ty and his assistant did a great job replacing pipes under our kitchen sink and attaching earthquake straps to the hot water tank. Ty was very patient in explaining the position of the straps. I would ask for him again in a heartbeat…. They were on time and finished very quickly.

Had a clog that was filling up my basement. The guys at Raymark found the problem and replaced the pipe. After the pipe was replaced they made sure the rest of the plumbing was in working condition. Their attitudes were great and they worked hard. Very satisfied customer.

Good morning, Raymark. Thanks, Anthony, for sending Dan to the rescue last week. We hadn’t been struck by an earthquake under our kitchen sink after all. Dan tightened the wobbly faucet, as well as its companion spouts, then wrestled the obstinate spray hose into line. Ingenious, he cobbled a defense so the hose could avoid tangling in the pipes. Dan is genial, and we really appreciate his visit.

Sincerely yours,
