It can be cheap because it is very basic but still good-looking and reliable. In this case, there is no problem. But beware of too low-priced faucets that offer you a ton of advanced features like pull-out spray wand, fingertip operation of the handle or even touch sensitivity. If your faith is strong enough, such can serve you well for some time, but I fear to make a guess how long or short it can be.
To disassemble unscrew the setscrew and pull off handle. Tighten the plastic adjusting ring inside the cap by turning it with a special flat adjusting tool-or fit tow screwdrivers into the slots and cross their blades to turn the ring. If your ball-style faucet with this type of cap is leaking from the spout, first try tightening the cap with channel pliers. Still leaking? Disassemble and replace worn/broken parts. Often you need to lift out the ball and replace the rubber seats and springs on both sides of the valve. If the faucet leaks around the spout, replace worn o-rings. Replace rotating ball only if clearly worn.
A small drip from a leaky faucet might seem like a little annoyance, yet it actually can cost you hundreds of dollars a year in water down the drain and next to nothing to fix. A leaky faucet is one of the most common home plumbing problems. Faucets are relatively easy to fix-once you know how they work and what to do to fix them.
Important: After making repairs to a disc faucet, it is imperative the handle in the ON position, then open the shutoff valves slowly. The ceramic discs can be cracked by the sudden release of air from the faucet. Once the water is running steadily, it is safe to close the faucet.
