Why is my water heater leaking from the bottom?
Condensation: In Northern Colorado, colder incoming water can cause the tank to “sweat,” especially after heavy hot water use.
Drain valve leak: The valve near the bottom can loosen or wear out over time
A leaking relief valve (T & P valve): Water can drip from the temperature/pressure relief valve line and end up pooling underneath.
A failing tank (most serious): If the internal tank has rusted through, water will collect at the base and the unit typically needs replacement.
What to do: If it’s actively leaking, shut off the cold water supply to the heater and call Cisco Plumbing. A true tank leak generally gets worse, not better.
How long does a water heater last in Colorado?
- Tank water heater: about 8–12 years
- Tankless water heater: often 15–20 years
Most water heaters in Colorado last (with normal use and average maintenance):
Hard water and mineral buildup—common in parts of Northern Colorado—can shorten lifespan if the unit isn’t maintained. Regular flushing/descaling helps your system last longer and run more efficiently. Call us to maintenance your tank.
Is tankless worth it for my home?
Tankless can be worth it if you want energy savings, longer lifespan, and space savings—and your home is a good fit.
Cisco Plumbing tip: If your main issue is running out of hot water, tankless may solve it—as long as it’s properly sized for your home’s peak demand.
Do you need a permit to replace a water heater?
In many Northern Colorado cities (including Greeley), a permit and inspection are commonly required for water heater replacement—especially if gas, venting, or location changes are involved.
Because requirements can vary by city and the type of install, Cisco Plumbing can help confirm what’s needed for your specific job and handle the process when required.
Why do I run out of hot water so fast?
- Water heater is undersized for your household or usage has increased (guests, laundry, longer showers).
- Sediment buildup in the tank (reduces usable hot water and efficiency).
- Thermostat setting too low or a failing thermostat/heating element (electric).
- Broken dip tube (cold water mixes too quickly with hot).
- Cross-connection or mixing valve issue (cold water blending into hot lines).
Common causes include:
Quick tip: Many homes do well with the thermostat set around 120°F (a common safe setting). If you’re still running out, Cisco Plumbing can test the components, check sediment levels, and confirm the heater is sized correctly.
