Ever wonder how long a plumbing product should last? It depends on a lot of factors but there are general guidelines you can expect. Water Heaters will depend on how much they are used and the quality of the water that goes through them. You can expect the average life to be between 7 - 14 years. A thermal expansion tank will greatly increase the life expectancy of your heater.
Garbage Disposals - Average life is 5-7 years. Sometimes a disposal will make a noise while it is running that will alert you it is ready to quit and sometimes it will start leaking. A tip - don't put 'stringy' vegetables in disposal such as lettuce or celery as it will clog the unit. Also, those lemon rinds that smell so good aren't so good for the disposal. The acid can wear away and damage the unit.
Sump Pumps - Average life is 3-5 years. A battery back up system will let you run the primary pump until it dies. This a the consumer choice but especially helpful if you have a finished basement.
Sewage Ejector Pumps - If you do have a finished basement, you probably have a sewage ejector pump. These have a life expectancy of 7 - 10 years.
Faucets - Longevity is based on the quality of the faucet, the type of water that goes through the faucet (hard or soft) and how it gets used.
Toilets - Most toilets need fill valves and flappers replaced every 5-7 years. Don't forget the toilets that aren't used on a regular basis, i.e., in a guest room. These need to be flushed regularly.
