How re-piping works in Fullerton

Corroded or failing supply lines cannot be patched forever. We replace aging galvanized and polybutylene pipe in Fullerton homes with copper or PEX.

Older Fullerton homes often have galvanized supply lines, and slab homes from the 1950s through the 1970s are prone to copper corroding under the foundation.

When to call for re-piping

Consider a repipe when water pressure keeps dropping, the hot water looks rusty or smells metallic, leaks have appeared in different places within a few years, a plumber has found heavy corrosion inside the pipes, or the house has polybutylene pipe that has already failed once.

What Fullerton homeowners should know

Our home city. Housing runs from 1920s craftsman homes to early-2000s developments.

  • Built before 1960Galvanized steel supply lines and cast iron drains. Galvanized rusts from the inside, cutting pressure and discoloring water. Cast iron narrows and eventually collapses. Both are due for replacement.
  • 1960s to 1980sCopper supply lines with cast iron or ABS drains. Copper holds up well but can develop pinhole leaks from hard water.
  • Built after 1990Modern plastic supply and drain lines. More resilient, though pipes under a slab are harder to reach when they leak.

Water hardness

Fullerton's water is very hard. The City of Fullerton publishes the current figure in its annual water quality report. Regular water heater flushing helps, and a softener is worth considering on older copper or galvanized lines.

Re-piping questions in Fullerton

What Fullerton homeowners most often ask us about re-piping.

How long does repiping a Fullerton home take?

Most single-family homes take about two to five days, depending on size and layout. Water service is kept on wherever possible.

Copper or PEX: which is better?

Both are durable and approved by code. Copper has the longer track record and handles heat and sunlight well. PEX is flexible, routes through walls with less drywall work, and resists freeze damage. The right choice depends on the layout of your home and your priorities.

Will repiping mean opening my walls?

Yes, because supply lines run through walls and ceilings. We keep the number and size of openings down and can coordinate the drywall repair.

What customers say

★★★★★

Great experience with Miguel and Steven! Fixed my stubborn kitchen sink clog. Very informative and respectful of my home in addressing the issue. Highly recommend!

I had an excellent experience with SoCal 1 Plumbing! Eliass came out to clear a blockage in my kitchen line by snaking it through the outside wall clean-out, and everything was done efficiently and with great care. He also installed new tubular drains under my kitchen sink to stop the leaks I’d been dealing with. The work was high-quality, and they even provided a 1-year warranty on parts and labor, which gave me peace of mind. Highly recommend their professional and reliable service!

I had a plumbing issue that needed to be repaired sooner than later. Miguel came out and knew how to fix it immediately. Miguel was professional, friendly and knowledgeable. I won't hesitate to call them in the future.
