There are a lot of weird plumbing questions floating around on the internet. Perhaps we develop these questions because we have nothing better to do but think and wonder when we’re showering or getting ready for our day in the bathroom.

However you stumbled upon your weird plumbing question, we’re not about to stand in your way on your quest for knowledge. Here are the answers to some of the weirdest plumbing questions we’ve heard asked.

How Much Does a Toilet Weigh?

The weight of a toilet varies from model to model. If you’re looking for a light toilet, you can find low capacity toilets at 50 pounds or so. If you’re looking for a heavy toilet, you may be able to find one at a hundred or more pounds. Whatever you do, don’t lift a toilet yourself—they are awkward to carry.

Can I Put My Toothbrush in the Dishwasher?

You can put non-electric toothbrushes in the dishwasher. If your dishwasher is functioning properly, it can clean your toothbrush. But we don’t know why you want to, as it’s not necessary to clean your toothbrush.

What is One Simple Plumbing Fact I Should Know?

The most practical thing for a homeowner to know is how to shut-off the water to their home. Doing so can save a lot of mess if you have a leak because you can stop the flow of water before we even arrive.

Is it Safe to Save My Shower Water for My Plants?

Yes, usually. You can install a greywater system that captures your shower water and feeds it to your plants. If you do, you need to be careful about what kinds of soap you use and avoid putting any chemicals, including hair dye, down the shower drain. Or, you can shower with a bucket and pour the water onto your plants yourself.

Why Aren’t Garbage Disposals Popular in Canada & Europe?

Garbage disposals are an American invention, and they’re only common here. In some places in Europe and Canada, putting food down your drain is illegal. They may not have the water treatment systems to handle it. But, it’s a crying shame because garbage disposals are so useful.

Which Way Should I Orient the Toilet Paper?

Ah, the age-old question: is “over” or “under” the right way to place the toilet roll in the toilet roll  holder? Well, the original patent for the holder does show the toilet paper roll oriented in the “over’ position, so it faces forward (instead of under so that it faces backwards.) However, we believe you should orient your toilet paper however you want to.

Why Does Flushing the Toilet Make the Shower Water Hot?

It’s not that the water in your toilet is hot. Instead, your shower uses a mixture of hot and cold water to create the shower temperature you want. When you flush the toilet, it demands the cold water. So the shower has less cold water to mix in and rises in temperature. By the way, newer plumbing systems can avoid this problem altogether.

Why Doesn’t Mario Do Actual Plumbing?

He’s too successful. In one of the original series, Mario and his brother Luigi were hired to kill the turtles and other creatures in the New York City plumbing system. You could say they’ve expanded their business beyond plumbing.
