Backflow Prevention

Backflow is any unwanted flow of used or nonpotable water, or other substances, into the potable water distribution system. Backflow can be caused by either backsiphonage or backpressure.

Cross Connection A cross-connection is a point in plumbing system where it is possible for a nonpotable substance to come into contact with the potable drinking water supply.

Backsiphonage Backsiphonage is backflow caused by negative pressure in a portion of the distribution system. If the system pressure drops due to a water main break or fire hydrant use, it can cause negative flow in portions of the distribution system.

Backpressure Backpressure is backflow caused when pressure in the supply piping is higher than pressure in the distribution system. Some possible causes of higher supply piping pressure can be caused by a pump, boiler or elevation difference.


Water Heaters

E&J Geothermal Inc. has over a decade of experience servicing, repairing, replacing, and installing conventional & heat pump water heaters in Solon, Cedar Rapids, Iowa City, North Liberty, & Coralville. Our expert team is ready to help you decide if a conventional tank or our heat pump water heater would be best for your application.

The Differences

Heat Pump Water Heaters
HPWH can save the average household approximately $250 per year on its electric bills compared to a standard electric water heater. Larger families - that typically use more hot water - will save even more!

Traditional Water Heaters
Traditional Tank Style Water Heaters are an economical choice and have a much quicker recovery time compared to an electric water heater along with affordable operating costs.

Things to Consider

The power supply the gas line you currently have in your house
The space occupied by the appliances
The level of usage (for few individuals or a larger group)
The Source with which it has to be operated (gas or electricity)
