You hear pipes knocking<\/a> in your home, and think nothing of it. It\u2019s just some sounds, right? What harm could it do?<\/p>\n\n\n\n

Knocking pipes do not spell immediate disaster, but it\u2019s like your plumbing system saying \u201cHey, I\u2019ve got something coming down the pipeline.\u201d It\u2019s a precursor.<\/p>\n\n\n\n

We don\u2019t want to worry you, but you should have some level of concern regarding knocking pipes. Let\u2019s talk about everything you need to know before you\u00a0call us for repairs.<\/p>\n\n\n\n\n\n\n\n

What Causes Pipes to Knock in the First Place?<\/h2>\n\n\n\n

If you hear knocking pipes, it doesn\u2019t instantly spell disaster or worry. Your water is pressurized (which is a good thing), so sometimes you hear the sound of pressurized water moving through your pipes.<\/p>\n\n\n\n

We call this the \u201cwater hammer.\u201d It\u2019s a noise that indicates your pipes are working as intended. No pressure means your plumbing isn\u2019t working as intended.<\/p>\n\n\n\n

But when that noise is much louder than you\u2019re used to, there\u2019s a reason to be concerned. This means that any pressurized air in the pipes could be leaking, and when that happens, water moves extremely quickly and makes a much louder knocking sound.<\/p>\n\n\n\n

What Can Be Done About Them?<\/h2>\n\n\n\n

You can flush your water line. It sounds scary, but we\u2019ll walk you through it.<\/p>\n\n\n\n

Make sure everyone in the house is aware of what\u2019s going on, then shut off your water at its source. This is called the water main. It should have a clear shutoff valve.<\/p>\n\n\n\n

Now you\u2019re going to flush the existing lines. Open all the faucets in your home and flush your toilet. Your sewer line will work regardless of whether your water main is on or not.<\/p>\n\n\n\n

Lastly, gently turn your water main back on. If you open it abruptly, you may run into the same pipe-knocking problem. Close your faucets once they\u2019re running and now the knocking should stop.<\/p>\n\n\n\n

How to Know When You Actually Need a plumber<\/h2>\n\n\n\n

Flushing your line can help, but what happens when it doesn\u2019t do the trick for your specific problem? That\u2019s when it\u2019s time to call in a plumber. You may need a plumber if:<\/p>\n\n\n\n
