If your plumbing seems fine on the surface, it’s easy to assume everything underneath is fine too. But plenty of the parts holding your system together wear out quietly, long before you ever see a puddle on the floor.
At Eco Plumbers, Electricians, and HVAC Technicians, our licensed plumbers inspect these exact components every day, from anode rods inside water heater tanks to the pressure reducing valve that protects your whole system. We know which parts fail quietly and which ones fail all at once, and the difference matters for your home.
Below is your cheat sheet: a lifespan chart for the plumbing components most likely to cause trouble when they’re ignored, plus what to actually do about it before a small problem becomes a flood in your laundry room.
How Long Do Common Plumbing Parts Really Last?
Most plumbing components don’t come with a warning light. They just wear down on a predictable schedule, and knowing that schedule is the easiest way to stay ahead of a failure.
| Item | Life Expectancy |
|---|---|
| Anode Rod (Water Heater) | 3-5 years |
| Washer Hoses (Rubber) | 3-5 years |
| Washer Hoses (Braided) | 5-7 years |
| Thermal Expansion Tank | 6-8 years |
| Sump Pump | 7-10 years |
| Garbage Disposal | 8-12 years |
| Hot Water Heater (Tank) | 8-12 years |
| Water Filtration/Softener Systems | 10-15+ years |
| Angle Stops (Under Sink/Toilet) | 10-15 years |
| Toilet Internal Components | 10-15 years |
| Gate Valve (Main Shut-Off) | 10-15 years |
| PRV (Pressure Reducing Valve) | 10-15 years |
| Shower Valves / Diverters | 15-20 years |
| Gas Flex Line & Shut-Off (WH/Stove) | 15-20 years |
| Outdoor Hose Bibs / Frost-Free Spigots | 15-20 years |
A part nearing the end of its range isn’t an emergency, but it is your cue to plan ahead instead of waiting for a failure to force your hand.
Why Aging Plumbing Parts Are Worth Watching
Ignoring a worn part rarely stays a small problem. Here’s what tends to happen when these components are left in place too long:
- A worn anode rod lets tank corrosion start from the inside out, which shortens the life of the entire water heater, not just the rod.
- Rubber washer hoses are one of the most common causes of sudden laundry room flooding, since they fail without warning and release a full line’s worth of water pressure at once.
- A failing pressure reducing valve lets pressure climb throughout your whole system, straining pipes, fixtures, and appliances that were never built to handle it.
Water pressure above 60 psi is where that strain really starts to add up. According to the U.S. Department of Energy’s Building America Solution Center, static service pressure above that threshold can cause pipes, hoses, and water heaters to leak or burst, make fixtures and appliances noisier, and shorten the life of your plumbing system overall.
Pro Tips for Staying Ahead of Plumbing Wear
A few simple habits go a long way toward catching problems while they’re still small and inexpensive to fix.
- Inspect annually, even before replacement is due. Rust, drips, and corrosion usually show up before a part actually fails, and catching them early is what keeps a $20 part from becoming a $2,000 repair.
- Upgrade when you replace. Braided stainless hoses last roughly twice as long as rubber ones, and ball valves hold up better over time than gate valves.
- Keep a simple record. Jot down install or replacement dates for your water heater, hoses, and valves so you’re never guessing how old a part really is.

When to Call a Professional Plumber
If you’re not sure how old your plumbing parts are or what shape they’re in, that’s exactly what a professional inspection is for. One of our licensed plumbers can walk through your home, check these components in person, and help you build a realistic plan for what to replace now versus what can wait.
This is especially worth doing before a big trip, a home sale, or simply once a year as part of regular water heater maintenance. Catching a worn anode rod or an aging PRV during a routine visit is a lot less stressful than discovering it during an emergency.
Knowing the lifespan of each part is only half the equation. If your home is older, the pipes and connections around these parts matter just as much as the parts themselves. Your next step is to read What’s the Best Way to Protect an Older Home’s Plumbing System? so you know exactly what else to watch for beyond this list.
And if a technician is already out at your home for a water heater replacement, that’s the easiest time to knock out any of the worn parts from this list in the same visit. Right now, when you purchase a new water heater, you can get $500 off a same-day plumbing repair, since our technician is already there. No separate trip, no second service call, just one visit that covers both.
If it’s been a while since someone took a real look at your plumbing, schedule a plumbing maintenance visit with Eco, and let one of our licensed plumbers tell you exactly where you stand, and whether this is the right time to take advantage of it.
FAQs
How do I know if my water heater’s anode rod needs replacing?
The clearest signs are rust-colored or metallic-smelling hot water, or visible corrosion when the rod is inspected. Most anode rods last 3 to 5 years, but water quality and usage can shorten that window, so an annual check is the safest habit.
How often should I replace my washing machine supply hoses?
Rubber hoses should be replaced every 3 to 5 years, even if they look fine, since they tend to fail suddenly rather than gradually. Braided stainless hoses last longer, typically 8 to 10 years, and are worth the upgrade if you’re replacing rubber ones anyway.
Does my pressure reducing valve ever need replacing?
Yes. A PRV typically lasts 5 to 10 years before it starts to drift out of its set range. Rising water pressure, banging pipes, or inconsistent flow at your fixtures are all signs it’s time to have it checked.
Can I replace these plumbing parts myself?
Some, like a hose, are a reasonable DIY swap. Others, like a PRV or an anode rod, involve working with your main water supply or opening a sealed water heater tank, where a mistake can mean a much bigger repair. When in doubt, a quick call to a licensed plumber is worth it.
What happens if I ignore worn plumbing parts?
Most failures in this category don’t build slowly. A worn hose or a corroded anode rod tends to fail all at once, which is how a part that costs a few dollars to replace turns into thousands of dollars in water damage.
