Tips For Long Life of Single Handle Faucet

Clean Faucet Regularly

Regular cleaning of the faucet is essential. If you don’t clean it, dirt, buildup, and grime will form on it. Also, its finish won’t look as new longer. Water spots and fingerprints will make the finish dull and unsightly.

When you clean it regularly or at the end of every day, its life increases and it looks new for longer and also works well without any issues.

Use Only Soft and Clean Water

Water quality also affects the life of a single handle tap. Hard water contains minerals that create buildup outside and inside the faucet. With time, the thickness of the buildup increase which affect the flow of water and eventually stop it.

Buildup also damages the internal parts of the faucet. When you use a water softener, it removes minerals from the water. If you see white spots near the spout, it means your water quality is not good and you should make it soft. It would be a good idea to install a common water softener in the house to clean water for all faucets.

Replace Faulty Parts

Single handle fixture is like a machine. When its different parts move, it initiates or stops the water flow. Like other machines, its parts also become faulty or damaged.

When there is a damaged part inside the faucet, it will cause a leak, water pressure issue, wrong temperature, or any other issue. It is not a small thing and you should not ignore it. If you ignore replacing a faulty part, with time it will damage other parts of the faucet. So, you should replace a faulty or damaged part as soon as you notice it.
