Judaline’s Plumbing Toolbox

Here are some of the most essential tools Judaline brings with her every day on the jobsite:

Channellock Pliers

Judaline’s go-to pair of pliers is this set of “baby” Channellocks. This compact pair of pliers is a versatile tool Judaline can use for a variety of tasks, while also small enough that she can easily carry it around in her pocket.

Four-Way Screwdriver

If you’re only going to carry a few tools with you, make one of them a multitool. Judaline always has this four-way screwdriver from Milwaukee on-hand while she’s working. It’s a versatile tool that comes with eight bits and three nut drivers.

Tape Measure

Trying to work with a low-quality, banged-up tape measure can really slow you down. That’s why Judaline always has this trusty, 25-ft. tape measure at her side. The blade is covered in an anti-tear coating and its fully-reinforced frame can withstand up to an 80-ft. drop.

Pipe Wrench

No plumber’s toolbox is complete without a quality pipe-wrench. Judaline carries around this heavy-duty wrench from RIDGID which features a fully-adjustable hook jaw that fits a wide range of pipe diameters.


When she’s on the jobsite, Judaline wears either a bandana or a beanie, depending on the weather. Her favorites are this beanie from Carhartt and this bandana from Tools and Tiara’s. Judaline founded Tools and Tiara’s, an organization dedicated to giving a helping hand to young girls and women who want to pursue a non-traditional trade.
