Pegasus makes a good cartridge to fit its faucet, using a hollow device made of metal or plastic you insert and fit tightly next to the faucet. The only thing you have to do when it needs repair is put a new cartridge in, and it usually will stop faucet leaks. The cartridge replacement procedure is simple.
Locate the sink's water valve and turn the water off. Turn the lever all the way to the right. You can usually find the valve under the sink. If your plumbing system does not have individual shutoff valves, close the main source of water. The shutoff lever is near your water meter.
Open every faucet in the house to allow any water remaining in the pipelines to drain out. Wait to begin disassembling your existing Pegasus faucet until water stops draining out.
Remove the handle from the faucet. Look for a small. hidden screw on the handle and remove it by turning it to the left. The handle will lift off after the hidden screw is removed. Sometimes you must jiggle the screw to get it to come off. All models are different, so check with the installation manual that came with your original faucet.
Look for the lock nut and ring that hold in the cartridge. If your Pegasus faucet has the lock nut and ring, you might not be able to pull out the cartridge until you remove them. Use a pair of pliers to pull out the cartridge very carefully.
Slide in the new Pegasus cartridge exactly where the old one was. Purchase this at any hardware store.
Put the faucet back together, following the steps in reverse order. Open up all water valves and then open the faucets. Make sure there are no leaks in the faucet after you turn on the water.
