When it comes to water hammer, hard water can contribute to its effects in two main ways: increased pressure and mineral buildup.
Hard water minerals can contribute to the accumulation of mineral deposits, known as scale, on the inner walls of pipes. These deposits reduce the internal diameter of the pipe, resulting in increased flow resistance and pressure build-up. When a valve is abruptly closed, the force exerted by the rapidly decelerating water can be intensified due to the increased pressure caused by the mineral scale.
Hard water minerals can also accumulate on the moving parts of valves and other plumbing fittings. This mineral buildup can hinder the smooth operation of these components and increase the likelihood of irregular water flow patterns. When water flow suddenly changes, the presence of mineral scale can exacerbate the force of the shockwave, making the effects of water hammer even more pronounced.
Preventing and Reducing the Effects of Water Hammer:
While hard water can amplify the effects of water hammer, there are several measures that can be taken to prevent or reduce its impact:
1. Install Water Hammer Arrestors:
Water hammer arrestors are devices designed to absorb the excess energy caused by water hammer. They act as shock absorbers and help minimize the vibrations and stress on the plumbing system. Installing these devices can help reduce the impact of water hammer, irrespective of water hardness.
2. Water Softening:
One effective way to combat the effects of hard water is to install a water softener system. Water softeners remove the calcium and magnesium ions responsible for water hardness and prevent mineral scale buildup. By reducing mineral deposits, water softening can help alleviate the pressure and force associated with water hammer.
3. Regular Maintenance:
Regular maintenance of plumbing systems is crucial in preventing water hammer. This includes inspecting and cleaning valves, fittings, and pipes to remove any mineral scale buildup. Additionally, it is important to address any leaks promptly to avoid sudden changes in water flow.
Water hammer can be a troublesome issue in plumbing systems, and the severity of its effects can be intensified by the presence of hard water. The higher pressure caused by mineral scale buildup and the increased force exerted by the shockwave can lead to more significant damage. However, by employing preventative measures such as water hammer arrestors and water softening systems, the impact of water hammer can be significantly reduced. Regular maintenance of plumbing systems is also essential in combating the effects of water hammer, regardless of water hardness.
