Thermal Expansion Tank Installation in Janesville
Many water utilities install pressure regulators or backflow devices that create a closed system. When water heats and expands, pressure spikes can strain your tank and fixtures. Code commonly requires a thermal expansion tank on these systems. We install a correctly sized expansion tank and pre-charge it to match your water pressure. This simple add-on can help your new heater last longer.

Power Vent Water Heater Replacement in Janesville
Power vent gas water heaters use an electric blower to push exhaust through PVC pipe, which lets them sit far from a chimney or roof flue. When the blower motor or pressure switch fails again and again, replacing the whole unit can be the better choice. We install new power vent models and confirm a dedicated outlet is available. Venting length and number of elbows must stay within the manufacturer's limits. Power vent tanks cost more but solve difficult placement problems.

40 and 50 Gallon Tank Replacement in Janesville
