Water Heater Repair & Installation in Waukegan

A failing water heater disrupts everything — no hot showers, no clean dishes, no laundry. Waukegan Plumber Pros repairs and installs both tank and tankless water heaters for homes throughout Waukegan and the surrounding Lake County area, including Gurnee, North Chicago, Beach Park, Zion, and Park City.

We work on all major brands and both gas and electric units. Common repairs include replacing failed heating elements, thermocouples, thermostats, anode rods, and pressure relief valves. If your tank is leaking from the bottom or is more than 10-12 years old, replacement is usually more cost-effective than continued repairs — we will be honest about which option makes sense for your situation.

For new installations, we help you choose the right size and type for your household. We handle the full installation including any necessary gas line or venting modifications, permits, and inspection scheduling. If your water heater fails completely and you need hot water restored the same day, call our emergency line — we stock common tank sizes on our trucks.

Every repair starts with a diagnosis. We explain what failed, what the fix involves, and what it costs before we begin. Call (847) 750-4509 to schedule.

Common Signs Your Water Heater Needs Attention

• No hot water or water not getting hot enough
• Rusty or discolored hot water
• Rumbling or popping noises from the tank
• Water pooling around the base of the unit
• Hot water runs out much faster than it used to
• Pilot light keeps going out (gas units)
• Higher-than-normal energy bills without increased usage

If you notice water pooling around the base, act quickly — a small leak can become a flood. Turn off the water supply to the heater and call (847) 750-4509. A leaking tank cannot be repaired and needs replacement.

Tank vs. Tankless Water Heaters

Choosing between tank and tankless is one of the biggest decisions Lake County homeowners face when replacing a water heater. Here is how they compare:

Tank water heaters store 40 to 80 gallons of hot water and keep it heated continuously. They cost less upfront (typically $800–$1,500 installed for a standard 50-gallon gas unit, according to national averages from HomeAdvisor). Tank units last 8 to 12 years. They are straightforward to install — especially as a direct replacement — and work well for most households. The tradeoff is higher energy use, since the tank reheats water even when you are not using it.

Tankless water heaters heat water on demand as it flows through the unit. They cost more upfront (typically $1,500–$3,500 installed, depending on capacity and whether gas line or venting modifications are needed). However, the U.S. Department of Energy estimates that tankless units are 24-34% more energy efficient than tank units for homes using 41 gallons or less per day. Tankless heaters last 20+ years and take up significantly less space.

Our recommendation: If your household uses a moderate amount of hot water and budget is a priority, a quality tank unit is a solid choice. If you want long-term savings, unlimited hot water, and have the upfront budget, tankless is worth the investment. We will walk you through both options based on your home's hot water demand and existing infrastructure.

Water Heater Maintenance

Annual maintenance extends the life of any water heater and helps prevent unexpected failures:

• Flush the tank annually to remove sediment buildup. Sediment insulates the heating element from the water, reducing efficiency and accelerating wear. This is especially important in Lake County, where mineral content in the municipal water supply varies by area.
• Test the pressure relief valve once a year. Lift the lever briefly — water should flow freely and stop when released. A stuck or leaking valve should be replaced immediately.
• Check the anode rod every 2-3 years. The anode rod attracts corrosive elements that would otherwise attack the tank lining. Once the rod is depleted, the tank itself begins to corrode. Replacing a $30 anode rod can add years to your water heater's life.

If you are not comfortable performing these tasks yourself, we offer maintenance visits. Call (847) 750-4509 to schedule. Regular maintenance ties in well with your overall bathroom plumbing health — we can check fixture connections at the same time.

FAQ

Should I repair or replace my water heater?

If your water heater is under 8 years old and the repair cost is less than half the price of a new unit, repair usually makes sense. If the tank is leaking, over 10 years old, or needing frequent repairs, replacement is the better investment.

How long does a water heater installation take?

A standard tank-to-tank swap takes 2 to 4 hours. Switching from tank to tankless or requiring new gas/electrical lines may take a full day.

What size water heater do I need?

A 40-gallon tank works for most 2-3 person households. Families of 4+ typically need a 50-gallon tank. Tankless units are sized by flow rate (measured in gallons per minute) — we calculate the right capacity based on how many fixtures you run simultaneously.

How long do water heaters last?

Tank water heaters last 8 to 12 years with proper maintenance. Tankless units can last 20+ years. Annual flushing and anode rod replacement are the two most impactful maintenance steps for extending lifespan.

Is a tankless water heater worth the extra cost?

For many Lake County homeowners, yes. The U.S. Department of Energy estimates tankless units are 24-34% more energy efficient for average-use homes. With a lifespan of 20+ years versus 8-12 for tank units, the long-term cost of ownership is often lower despite the higher upfront price.

Can you convert from tank to tankless?

Yes. Conversion requires modifications to your gas line (for gas tankless) or electrical panel (for electric tankless), plus new venting. We handle all of this, including permits and inspections. A typical tank-to-tankless conversion takes one full day.

What should I do if my water heater is leaking?

Turn off the cold water supply valve at the top of the heater. If it is a gas unit, turn the gas valve to the "pilot" or "off" position. Place towels or a bucket under the leak. Then call (847) 750-4509 — a leaking tank cannot be repaired and needs replacement before it causes water damage.

Do you offer same-day water heater replacement?

Yes. We keep common tank sizes on our trucks. If your water heater has failed completely and you need hot water restored quickly, call (847) 750-4509 and we will do our best to install a replacement the same day. We serve all of Lake County including Waukegan, Gurnee, North Chicago, Beach Park, Zion, and Park City.
