Heavy Rain and Blocked Drains: What a Plumber Sees 


Alright, folks, let's chat about rain and drains, something I deal with a lot. As a plumber, when it rains heavily, it's like my phone doesn’t stop ringing. Why? Because heavy rain can really mess with your drains. Here’s the lowdown from someone who sees this stuff all the time.


First off, when it buckets down, everything gets washed into the drains – leaves, dirt, the whole shebang. If your drains are already blocked, even a little bit, all this extra stuff just makes it way worse. Suddenly, you've got a full-on blockage and water’s not going anywhere it should. Trust me, I've seen some wild things get washed down drains!
Then there’s the sheer volume of water. Our drains are built to handle rain, sure, but when it’s a real downpour, they can get overwhelmed. It’s like trying to drink from a fire hose. And that's when you get those nasty floods in your yard or, even worse, inside your house. Nobody wants that!
Another thing I see a lot is how heavy rain moves soil. All that water washes soil and sand into the drains, and over time, it builds up. It’s like sediment in a fish tank, but way messier. This can slowly block your drains without you even realizing until, boom, heavy rain comes and it's a full-blown problem.
So, what can you do to save yourself a headache and maybe a call to me? A little bit goes a long way:

Keep things clear: Check your gutters and drains now and then. Pull out the leaves and twigs. It’s a bit gross, but it’s way better than dealing with a flood.
Get some guards: Put those drain guards in. They stop big stuff from getting in and are cheap and easy to install.
Look at your yard: Make sure your yard slopes away from your house. You don’t want rainwater running towards your foundation, where it can get into your drains and cause issues.
Check in with a plumber: Get your drains checked every so often. Especially if you live somewhere that gets a lot of rain. We can spot problems before they become big, wet disasters.

Basically, heavy rain can really test your drains. A little bit of prep can save you a lot of trouble, and maybe a call to your friendly local plumber. Stay safe and dry out there!
