1. Your hot water tank is making a strange noise.
Noises can be due to many reasons but just like a car, noise is generally a sign that something is not operating correctly in your hot water tank unit. It's advisable to contact a technician to asses your hot water heater.
2. You are not getting hot water through the house.
If you are not getting hot water, or if the amount has substantially decreased, it's advisable to contact a hot water tank technician to asses your water heater immediately.
3. Your hot water tank is more than 10 years old.
Hot water tanks have a life span of 10 years. Problems can occur and keeping water heaters much longer than their average life span, could damage the unit, causing potential harm to your home. We advise contacting a technician to take a look at your hot water tank in order to assess it's current standing.
