Ever since our house flooded at midnight (though thankfully First We slept in), my wife and I are diligent about installing water alarms throughout the house, so we’ll get critical warning as soon as something leaks or backs up.
Well, the other night, the alarm under the kitchen sink went off while the dishwasher was running – and, sure enough, water was coming out of the sink drain. Luckily, I was able to turn off the water and clean everything up before my cabinets and floors were completely ruined. I started investigating the problem, and about three seconds later, it became clear: There was a huge gap in my sink drain:

It was truly astonishing – a piece of pipe was simply gone, and what was left was as fragile as tissue paper. I called a few plumbers, but no one could get in touch with me for a few days (plumbers have a very narrow definition of the term “emergency”). I faced the prospect of not being able to use my kitchen sink or dishwasher for a period of time or risk causing further damage to my home.
But I had another option: a quick solution with epoxy putty.
Epoxy putty is an easy, water-resistant solution to leaks
Epoxy putties all generally work the same way: They contain a resin and a hardening agent, and when these clay-like ingredients are combined, a chemical reaction causes them to harden instantly, no matter what shape you make them. There are some major brands to choose from, including JB Waterweld, PC-Plumbing Epoxy Putty, Otay Stick Fix-It, and Loctite Epoxy Putty. Coincidentally I had some Waterweld, so I used that to save my kitchen, but any of these products would probably work just as well.
How to Fix Epoxy Putty Leaks Quickly
The process is pretty straightforward: First, you remove as much putty as you think you’ll need (wear gloves – this stuff can irritate your skin):

What do you think so far?

Now apply the putty to your leak. In my case, I used almost the entire package to clog the large hole in my kitchen drain:

Different products will have different working time and hardening time. Waterweld takes about 25 minutes to set, so you need to work relatively quickly. Fortunately, temporary plumbing repairs don’t need to be pretty. I simply rolled it over the groove, pressed it into place, and worked the edges to create a seal. It is important to note that epoxy putty products like this are meant for low-pressure repairs; Although they can potentially plug pinhole leaks in high-pressure pipes, repairs of this size will not work under any type of intense water pressure.
Waterweld cures in about an hour, so after waiting it out, I went to run water in the sink for a while to test it – and not a drop came out. Then I ran the dishwasher with the water alarm on and had no problems. The putty repair took three days, requiring a plumber to attend (to add insult to injury, he was not impressed with my spectacular temporary fix either). In the meantime, we were able to use the kitchen normally without the risk of further water damage. For a product that costs around $7, that’s not bad.
