A person who fixes pipes is commonly referred to as a plumber. Plumbers install, repair, and maintain plumbing systems, including water supply and drainage systems. They may work in residential, commercial, or industrial settings, addressing issues such as leaks, clogs, and pipe installations.
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.
A plumber is a tradesman (or woman) who mends burst water pipes.
