By ensuring no air gets into the pipes, by tighteneing all joints correctly, and making sure that pipes that run horizontally are slightly inclined toward the upward flow of the liquid. About 2º to 3º off the horizontal is good.

There´s no way to prevent it since in a regular pump system the worst scenario is when there is a blackout and the fluid is no longer pumped because of the pump trip. All we can do is attenuate it. For that you have pressure vessels, air chambers, one-way tanks, and other elements.

Why do pipes rattle when the toilet flushes?

Water hammering on any quick closing valves


How do you fix water hammering or knocking sounds in a pipe such as a bathroom faucet?

Knocking or hammering on your water pipes is caused by the air chambers within the pipes, which are designed to cussion the pipes against the pressure of the water that flows through them, being depleted to some degree. This is easily fixed, provided that you go about it in the right way--you do not need to call a plumber.First of all, and I can't stress how important this is, you MUST turn off the main water valve in your house to prevent any further water from entering the pipes--do this first.Next, turn on every faucet (tap) and flush all of the toilets until no more water will come out. When you are sure that everything has been drained dry, turn OFF all of the faucets (taps).Now turn the main water valve back on slowly. What this does it to allow the air chambers to be replenished with the correct amount of air to prevent the shock from the water flowing under pressure.
