Is Your Water Heater Failing?
The most common reasons customers call us, starting with the most frequent:
- Leaks or water damage around the unit
- No hot water, or inadequate heating
- Electrical, component, or error-code issues
- Pilot light, ignition, or gas-control failure
- Rumbling or popping noises
- Unit older than 10 years, or visible corrosion
A unit under warranty with a single, minor issue is usually worth repairing. A tank older than 8-10 years, or one where repair costs approach the cost of a new unit, is usually a better candidate for replacement. An on-site estimate from a Roto-Rooter technician can tell you exactly which makes sense for your situation.

Frequently Asked Questions
How long does a typical water-heater installation take?
Most installations take about 2–4 hours. Complex upgrades or code-related work may take a little longer.
What size water heater is right for my home?
The size you need depends on your household size and how much hot water you use. For most families, a 40 to 50-gallon tank is sufficient. However, homes with higher water demands or those using tankless systems are typically sized according to the flow rate.
How often should I schedule maintenance for my water heater?
Once a year is ideal. Regular flushing and safety checks help prevent breakdowns and extend the life of the unit.
How do I know if my water heater needs to be repaired or replaced?
If you're seeing leaks, inconsistent hot water, strange noises, or if the unit is over 8-12 years old, it's likely time for repair or replacement. We can diagnose it on-site.
What's the difference between tank and tankless water heaters?
Tank heaters store hot water and are usually more affordable upfront. Tankless systems heat water on demand, offer endless hot water, save space, and are more energy efficient.
What size water heater do I need for my home?
It depends on your household size and hot-water usage. Most families need a 40-50 gallon tank, while high-demand homes or tankless systems are sized based on flow rate.
