I’ll show you exactly how to replace the cartridge in a quarter turn washerless faucet. To find the right cartridge for your faucet, explore our website below. To begin, you’ll a set of cartridges, a crescent wrench, Phillips screwdriver, a small flat blade screwdriver (or one-eighth inch allen wrench) and a cloth. Quarter turn faucets are another common faucet found in homes. Unlike compression faucets, quarter turn faucets don’t use washers. As the handle is turned, a small disc inside the cartridge opens up to allow water to flow out. Leaks can be caused by worn out o-rings and cartridges. Replacing the cartridges is a common fix and only takes a few minutes. First, close the shutoff valve. Turn on the faucet to completely drain the lines and relieve any built up pressure.
Next, plug your sink so you won’t lose any pieces during the repair. First, pop off the handle caps with a flat blade screwdriver. Now, use a Phillips screwdriver to unscrew the handles from the cartridge. Use a crescent wrench to remove the bonnet nut from the cartridge. Once the nut is off, remove the cartridge. If you need extra leverage, use pliers to pull on the stem. Now, soak up the water in the faucet shank.
First, align the tab on the new cartridge to the slot on the faucet. Now, screw on the bonnet nut and tighten with a crescent wrench. Reinstall the handle and pop the caps back on. Finally, turn the water back on. Test the faucet and check for any leaks.
