Common Time Frames Most Plumbing Items Are Good For

Knowing when to replace your plumbing fixtures is important. Here are the usual time frames for some of the most common plumbing items in your home.


Water Heaters

Tankless water heaters should be replaced every 20 years. Traditional water heaters have an average life span of 10 to 15 years. Both types can last longer if properly maintained. You should start looking for a new heater if there’s rust or leaks around your current unit. A new water heater is also recommended if the pilot light in your existing unit keeps flickering out or if the thermostat is broken. Read more on water heater repair and installation.

Garbage Disposals

The average life expectancy of garbage disposals is about 10 years. However, your garbage disposal may need to be fixed or replaced if you are experiencing any of the following:

  • Frequent clogs
  • Odors that won’t disappear no matter how much and how often you clean the unit
  • Resetting the garbage disposal more often
  • The unit is taking longer than usual to break down food. Read more on garbage disposal repair and installation.

Water Softeners

Water softener systems have an average life span of 10 to 15 years. With proper maintenance, these fixtures can last longer than that. However, once your system reaches its average life span, you have to consider whether it is still worth fixing. The cost of fixing an older unit can add up if repairs are needed more frequently. Getting a new unit might be the better option. Read more on water softeners.


Brass pipes and galvanized steel pipes can last for 80 to 100 years. Copper pipes have an average life span of 70 to 80 years. If you have an older home, you may need to replace your piping sooner. A plumbing technician can assess your piping and tell you if a replacement is necessary. Read more on repiping.


Drains can break down due to old age, tree root growth, and other factors. The average life span of cast-iron pipes is 80 to 100 years. Plastic or PVC pipes can last for 25 to 40 years. Read more on drains, cleaning and repair.

Other Fixtures

It’s hard to know when some plumbing fixtures will stop working. The average life span of plumbing fixtures can vary. Sump pumps usually last for 4 to 7 years. Well pumps have an average life span of 10 to 12 years. Kitchen faucets need to be replaced every 15 years. Toilet tank components can last up to 5 years.


The average life span of toilets is 50 years. If your toilet is older than 25 years, you may need to replace it with a newer one. Newer units use less water, which can help you save money on your water bills. Fill valves, trip levers, flappers, plumbing connections, and fittings need to be replaced every 4 to 5 years. Read more on toilet repair and installation.

Sewer Lines


Sewer Line Repair – Perma Liner Installation

Clay sewer lines have an average life span of 50 to 60 years. PVC pipes can last for 100 years. However, you may need to replace your sewer lines sooner if there’s a strange or foul odor in your yard. Another telltale sign of a problem with your sewer line is hearing gurgling sounds in the bathroom. Read more on sewer line repair and replacement.
