This is also known as Water Hammer and can cause considerable damage. €� Because each “Air in a pressurized water system is very dangerous as it can move very quickly through the supply lines and consequently result in serious water hammer,” Johnson told Life's Little Mysteries. The new pre-charge function eliminates the problem of water hammer and extends system life by gradually filling the pipeline. To avoid this, remove the sprinkler heads at the highest point of each zone. You can also install a pressure-reducing valve on the water supply line for the house if the water pressure is very high (which may occur in low-lying areas). By Jrbott: Install a water hammer unit in the line to absorb the shock wave. This can create massive geysers, which can damage the turf and pipes. According to Michael Johnson, a civil engineer at the Utah Water Research Laboratory who models fluid flow in sewer systems, the consequences of mass flushing would range from negligible to pipe explosions depending on where you are. When flow is suddenly stopped, flow inertia causes a pressure surge at the valve, with a shockwave propagating through the pipeline. This occurs when a surge of water pressure bursts out of the pipes, resulting from a rush of water flowing through the system all at once. If you are on a dual system with your neighbour, did ACTEW install a new water meter and hammer arrestor to both houses. Excess water pressure can also cause this so have your plumber check the water pressure in the system. One of the greatest risks during initial start-up is water hammer. It can happen on down gradually. The faster the water When the water lines are empty, turn off all the faucets. Begin filling the irrigation system main line (located between the water source and zone valves). This is much more than a domestic-water system is tested and rated for, so these shock waves can be destructive to water pipes. We do share a line with the house next door to the main water pipe across the road, but next door activity has been ruled out – why would anyone turn a tap on and off at regular intervals for hours during the middle of the night and why in any case should it register on our meter? However, we do recall that some . The problem you are describing is often called water hammer. The problem with a simple vertical pipe is that the bubble can get dissolved into the water, so a sealed system using a rubber bladder can be purchased (this solution also allows other orientations besides vertical).
