Once the lines are cleared, feel free to turn your main valve back on. It is important to do this slowly so that the air chambers between and around your pipes have time to refill before the water courses back into them. However, now that the pipes were fully emptied, the knocking sound should be completely gone.

Lightweight and engineered with the power of dual-driver acoustics, the reimagined Powerbeats2 Wireless Bluetooth Stereo Headphones deliver the premium sound and performance needed to propel you through rigorous workouts.

Powerbeats2 are Beats by Dre's first wireless earbuds. There may have been some big changes at Beats recently, but it's still all about the headphones. The newest addition to the (ever growing) family is the PowerbeatsÂ². As the name suggests, they are a revision of the original sport-friendly buds from Beats, but this time they're wireless -- Beats' first in-ears to cut the cord. The PowerbeatsÂ² keep the (albeit modified) hook-over-the-ear design, but liberate heads from handsets via Bluetooth 4.0.
