A leaking faucet can seem like a small problem at first, but if left unfixed for long, could worsen. Once the leaking increases, water losses can lead to higher water bills or cause rusting of metals in its path. Knowledgeable homeowners should fix the leakage as soon as it appears. The services of a qualified plumber might be sought if the problem is severe. Leakage could be caused by a wide variety of reasons, among them;
Valve seat corrosion
The valve seat is the connection between the faucet and the spout. After some time, the minerals and chemicals or sediments in the water can start corroding the valve seat. The corrosion may become adverse with time and lead to leakages. A corroded valve seat is seen through leakages in the spout area.
Worn out or faulty washers
Rubber washers usually wear down after prolonged use due to the constant pressure applied by the valve seat. The washers may also have been installed incorrectly leading to gaps or misalignment with the valve seat. Likewise, if a washer of the incorrect size is installed leakages are likely to happen.
Loose stem screw parts
If water is leaking from the faucet handle, the problem could be a loose or worn out O ring. The stem screw holds the handle in place. The two are connected by the O ring to prevent water from seeping out. After prolonged use, it can wear out thus letting water out. Other parts that can result in leakages include the adjustment rings and the packing nuts.
The sediments and chemicals in piped water can corrode the seals after prolonged use. The seals are crucial in ensuring the faucet works appropriately. Continued corrosion of the seals usually causes the faucet to leak.
Regardless of what causes your faucet to leak, you should try to fix the problem as soon as you first notice it. If the leakage is severe, you should call a qualified plumber to come check it out immediately. Regular cleaning and maintenance of the water system can help avert many of the problems that cause faucet leakage.
