PODCAST TRANSCRIPTS

Wel­come to Fri­day’s Flash­cards with Math, Sci­ence, His­to­ry. The pod­cast where we explore the fas­ci­nat­ing ways math and sci­ence shape our world. Hi, I’m Gabrielle BIrchak.

I have a back­ground in math, sci­ence, and jour­nal­ism. And this week, odd­ly enough, is Fix a Leak week. Today, we’re div­ing into a prac­ti­cal top­ic, plumbing.

Specif­i­cal­ly, we’re going to talk about emer­gency fix­es for a leaky pipe under your kitchen sink using some quick math and physics tricks. These tips can help you slow or even tem­porar­i­ly stop a leak until a plumber arrives. So whether you’re deal­ing with a pipe joint, a crack, or a hole, I’ve got you covered.

Not only will I share step-by-step solu­tions, I will explain the physics behind why they work. So let’s get start­ed. Before we jump into the quick fix­es, let’s under­stand why leaks hap­pen in the first place.

Pipes under your sink are exposed to water pres­sure, tem­per­a­ture changes, and phys­i­cal stress. Over time, pipe joints can loosen, small cracks can devel­op, and exter­nal forces can cause holes. Under­stand­ing the forces at play will help us cre­ate bet­ter tem­po­rary fixes.

One key physics prin­ci­ple here is flu­id pres­sure. Water moves from high pres­sure to low pres­sure, mean­ing that any weak spot in your pipe will allow water to escape. Our goal is to cre­ate a seal that coun­ter­acts this force, either by redi­rect­ing the pres­sure, cre­at­ing a vac­u­um, or phys­i­cal­ly rein­forc­ing the weak­ened area.

So a pipe joint is where two pipes con­nect. Over time, these con­nec­tions can loosen, lead­ing to leaks. So here’s a quick fix.

One, turn off the water sup­ply. First, shut off the water to reduce pres­sure on the leak­ing joint. If there’s no ded­i­cat­ed shut-off valve, turn off the main supply.

Two, apply pipe thread tape. So if you have Teflon tape, also called plumber’s tape, wrap it around the threads of the joint. This tape fills in gaps and pre­vents fur­ther leak­age by cre­at­ing a bet­ter seal when the joint is tightened.

Three, use a wrench to tight­en the joint. A loose con­nec­tion might just need to be tight­ened. Use an adjustable wrench to care­ful­ly tight­en the joint.

Care­ful­ly. Don’t over­do it. Too much force can crack the fitting.

Four, tem­po­rary rub­ber wrap. So if you don’t have Teflon tape, use a strip of rub­ber, like a rub­ber glove or a bicy­cle inner tube. Cool, huh? You can use that around the joint and secure it tight­ly with zip ties or a hose clamp.

The rub­ber expands under pres­sure, help­ing to seal the leak. So why does this work? Well, pipe thread tape acts as a sealant by fill­ing micro­scop­ic gaps in the joint. And two, rub­ber wraps work due to com­pres­sion mechan­ics, which increase sur­face ten­sion, reduc­ing water escape.

It’s all so cool. I love physics. So a cracked pipe is a bit trick­i­er, but you can still cre­ate a tem­po­rary fix with some sim­ple tools.

One, turn off the water sup­ply. Okay, this pre­vents the crack from wors­en­ing while you work. Two, use epoxy putty.

If you have plumber’s epoxy put­ty, knead it and press it into the crack. It hard­ens with­in min­utes, seal­ing the leak tem­porar­i­ly. Three, DIY tape and rub­ber solution.

So if you don’t have epoxy, take a piece of rub­ber from a glove, an inner tube, or even some plas­tic wrap and wrap it around the crack. Secure it tight­ly with elec­tri­cal tape, duct tape, or zip ties. And then four, clamp it down.

If you have this avail­able, use a hose clamp or even a C‑clamp to keep pres­sure on the patch. This pre­vents water from push­ing through. Why does this work? Well, epoxy put­ty forms a sol­id mechan­i­cal bond when it hard­ens, tem­porar­i­ly seal­ing the crack.

And two, rub­ber and tape solu­tions use hydro­sta­t­ic pres­sure. As water push­es against the rub­ber, the tight wrap rein­forces the pipe struc­ture. I love physics.

Okay, now let’s talk about fix­ing a hole in a pipe. If your pipe has a hole, a fast trick can help stop the leak until the plumber arrives. Notice I keep say­ing until the plumber arrives.

Yeah, some­times you got to get a plumber involved. First, to fix the hole in the pipe, turn off the water sup­ply. Always, always the first step.

Two, coin and clamp method. Okay, what this is, is if the hole is small, place a coin direct­ly over it and secure it tight­ly with a hose clamp or a zip tie. The coin dis­trib­utes the water pres­sure, block­ing the hole effectively.

Okay, the next step. Three, a plas­tic bot­tle wrap. Cut a plas­tic bot­tle so that it can wrap around the pipe.

Secure it tight­ly with duct tape, hose clamps, or zip ties. The air trapped inside cre­ates a vac­u­um effect, reduc­ing the leak. And four, rub­ber and tape method.

Just like for a crack, wrap­ping the hole with rub­ber and secur­ing it with tape can cre­ate a nice short-term seal until the plumber arrives. Okay, so now, why does the coin trick work? Well, because it spreads pres­sure over a larg­er area, mak­ing it hard­er for water to escape. The plas­tic bot­tle method works on the prin­ci­ple of neg­a­tive pres­sure, where trapped air pre­vents water from escap­ing as easily.

And final­ly, the rub­ber and tape method relies on com­pres­sion seal­ing, which redi­rects the water pres­sure. So while these tricks can save you from a big mess, they’re not per­ma­nent solu­tions. You got­ta call a plumber.

And call them as soon as you can, okay? But to pre­vent future leaks, here are a few tips. One, inspect your pipes reg­u­lar­ly for signs of wear. Two, avoid over-tight­en­ing the joints.

This can weak­en the fit­tings. Three, use pipe insu­la­tion to pre­vent crack­ing due to tem­per­a­ture changes. And then four, know where your water main shut off valve is to act quick­ly in emergencies.

Or in our case, when you’re get­ting ready to throw a par­ty, and all of a sud­den, the water spews a leak. It’s always right before a par­ty, isn’t it? So, it’s Fix-A-Leak Week. I hope these tips help, and I hope they help to remind you to inspect your pipes.

So that’s it for today’s episode of Math Sci­ence His­to­ry. I hope you enjoyed today’s Flash­card Fri­day, and I hope you found these emer­gency plumb­ing fix­es help­ful. Remem­ber, a lit­tle math and physics can go a long way in solv­ing every­day problems.
