Preventing Frozen Pipes
Thawing Frozen Pipes
If some faucets and appliances are dry and others still work, a water line is frozen inside the building. Run a damp rag along exposed water pipes. Likely areas are near exterior walls or in unheated areas. Your ice plug is where you see the frost appear.
1. Shut down of water mains or low main pressure – air bubbles may be present in water after there has been a break or draining of a water main.
2. Water can absorb more air at higher water pressures- When this water that is under pressure experiences a reduction in pressure (when water leaves a spigot to fill a glass) it releases air bubbles and that results in a milky appearance
3. Temperature changes -Cold water can hold greater amounts of air than warm water. Therefore, air is released upon warming cold water saturated with air. The air released is the form of small air bubbles, which gives the water a milky or carbonated appearance.
4. Hot water tank malfunction or when thermostat is set higher than 140 F - water releases air bubbles when heated. For this reason hot water usually contains some air bubbles. This condition is most noticeable in the winter months. It is also noticeable in the first water drawn from a hot water tank after the tank has been idle overnight.
5. Warming of cold water lines – cold water lines in basements, above the ground or attached to sides of buildings when warmed by internal home heat or exposed to the sun.
6. Zinc- can be dissolved from galvanized piping and form bluish -white deposits in water. Since distribution piping is not made of zinc, this usually is caused by galvanized pipes within the residence. Restaurants are sometimes the source of milky water caused by zinc where water passes through coils of galvanized pipe surrounded by ice.
If your water appears milky, cloudy, or contains air bubbles, consult this list of potential causes. If you still feel there is a concern, please contact us at 724-776-4806.
