Free Tool

Do you need a repipe or a new water heater?

Enter the year your home was built, the year your water heater was installed, or both. We'll tell you what's typical for plumbing that age.

How we estimate it
  • Before ~1960: galvanized steel pipes were common. They rust from the inside and usually last 40–60 years.
  • ~1978–1995: some homes used polybutylene, a gray plastic pipe known for sudden failures.
  • Copper: can last 50+ years, but Southern California's hard water can cause pinhole leaks as it ages.
  • Water heaters: tank units last about 8–12 years; tankless units about 20.
Water heater type

These are general estimates based on typical lifespans, not a diagnosis. Pipe material, water quality, and maintenance all matter, so an in-person inspection is the only way to know for sure.

Simple Plumbing Solutions

Frequently asked questions

Straight answers from licensed plumbers. Still not sure? Give us a call. It costs nothing to ask.

Do I need to hire a plumber?

Not always. Simple projects like replacing a P-trap, swapping a faucet, or unclogging a drain are very DIY-friendly with the right tutorial. If you're unsure, give us a call. We're happy to walk you through it over the phone, and if it turns out you need help, we're here for that too.

What's the difference between a plumbing repair and a remodel?

A repair fixes what's already there: a leak, a clog, a broken fixture. A remodel relocates or adds new plumbing, which typically requires permits and inspections. Not sure which your project is? We'll help you figure it out before you spend a dime.

How do I maintain my plumbing to avoid costly repairs?

Avoid pouring grease down the kitchen drain, use a hair strainer in shower drains, and never flush wipes, even "flushable" ones. Check under sinks every few months for slow drips, and flush your water heater annually. With copper lines, watch for green discoloration near fittings, an early sign of corrosion.

How do I know if I have a serious plumbing problem?

Warning signs include low water pressure throughout the home, a sewage smell indoors, water stains on ceilings or walls, or multiple slow drains at once. One slow drain is usually a clog. Several often point to a deeper issue in the drain-waste-vent system.

What is rough-in plumbing and how long does it take?

Rough-in is the first phase of new-construction plumbing: installing drain, waste, vent, and supply lines before the walls are closed. For a typical single-family home it takes 2–5 days, depending on the number of bathrooms and whether gas lines are involved. We coordinate with your framing crew and inspection schedule.

What's the difference between PEX and copper pipe?

Both are reliable. Copper is time-tested and long-lasting. PEX is flexible, faster to install, and more freeze-resistant, which makes it popular in new construction. We work with both and will recommend the right fit for your project, local code, and budget.

How do I shut off my water in an emergency?

Your main shutoff valve is usually near the water meter, under a sink, or where the main line enters the home. Individual fixtures also have their own shutoff valves. If you can't find yours, call us. We'd rather help you locate it now than have you scrambling during a leak.

Why did my water bill suddenly spike?

Something is almost always running that shouldn't be. The most common cause is a running toilet, since a worn flapper can silently waste hundreds of gallons. Other culprits: a slow leak under a sink, a dripping hose bib, or a leak inside a wall.

How long does a water heater last?

Tank water heaters usually last 8–12 years; tankless units can last 20+ with proper care. Replace yours if you notice rusty water, rumbling or popping sounds, inconsistent temperature, or corrosion around the unit. An annual flush can significantly extend its lifespan.

What does an annual plumbing inspection include?

We check supply lines, drain lines, water heater condition, visible pipe corrosion, water pressure, and fixture performance. Our annual maintenance plan is $149 and includes a full inspection and a water heater flush. Catching small issues early can save you thousands.

When does a house need to be repiped?

Homes built before about 1960 often still have galvanized steel pipes, which rust from the inside and typically last 40–60 years. Homes from roughly 1978–1995 may have polybutylene, which is prone to sudden failure. Copper from the 1960s–80s can develop pinhole leaks with age, especially with Southern California's hard water. Low pressure, rusty water, or repeat leaks are signs it's time for a repipe. Try our free repipe checker.
