What is corrosion?

Corrosion is the gradual decomposition or destruction of a material by chemical action, often due to an electrochemical reaction.  Corrosion may be caused by stray current electrolysis, galvanic corrosion caused by dissimilar metals, or differential-concentration cells.  Corrosion starts at the surface of a material and moves inward.

In terms of water, essentially, the water slowly eats away at a metal surface causing damage over time.

Corrosivity is an indication of the corrosiveness of a water.  The corrosiveness of a water is described by the water’s pH, alkalinity, hardness, temperature, total dissolved solids, dissolved oxygen concentration, and the Langelier Index.

Dare County Water Department uses corrosion inhibitors to slow the rate of corrosion.  Professor Faucet uses his surfboard turned tool kit to fight Corrosion. 

What causes pipes to freeze and how can I avoid burst pipes?

Pipes freeze when the temperature around them drops below a certain temperature.  Pipes that freeze are cooled from the outside in.  Since water expands when it freezes it increases in volume from its liquid state.  The increase in volume is the main cause of a burst water pipe.  As the temperatures drop below freezing, the water starts to freeze from the outside in, expands in size and creates a build up along the pipes, increasing the pressure on the liquid water remaining in the pipe.  Because water is difficult to compress the pipe will burst if there is no other means for relieving the increased pressure.

Here are some ways to prevent pipes from freezing:

• Insulate pipes: Use foam rubber or fiberglass sleeves to wrap pipes in unheated areas. 

• Let water drip: Running water, even at a trickle, can help prevent pipes from freezing. This is because it relieves pressure that builds up between the faucet and the ice blockage. 

• Drain outdoor pipes: Disconnect and drain garden hoses and outdoor faucets before winter. 

• Adjust the thermostat: Set your thermostat to be above 55°F during cold weather. 

• Open cabinet doors: Opening cabinet doors can help warm pipes. 

Older pipes, exposed pipes, and uninsulated pipes are more likely to burst during extended cold spells. 

Why do tree roots puncture water lines?

Answer:  When a tree is not getting enough water or moisture it will naturally grow in the direction of water.  When water lines or water pipes have cracks or leaks they release moisture into the surrounding soil, which acts as a magnet for tree roots.

Tips from "Rootie":  

1. Keep trees and plants well watered.

2. Plant away from water lines, water lines or septic tanks to prevent roots searching for water and causing greater damage.

3. Use a pipe liner

4. Use a root barrier

5. Repair leaks promptly

Introducing Professor Faucet's latest nemesis, the "Summer Slacker"! 

Pop over to the "Professor Faucet in Action" webpage to answer this month's pop quiz, "What season has the highest water consumption percentage?"

Tips from "Summer Slacker":

1. Check your outdoor fixtures for leaks.

2. When filling your swimming pool make sure to set a timer to remind you to turn the hose off.  A forgotten hose in a pool can create a high water bill.

3. Check your irrigation system.
