Faucet Leaking from Hole in Stem: How to Fix When Turned on

Leaking Faucet

Faucets just like other plumbing elements can break and cause a leaking hole on the stem. These holes are not good news.

Even if they are small and insignificant, they can cause water damage to your whole property. Therefore, the holes need to be attended to as soon as they are noticed to prevent bigger problems. 

What causes a faucet to leak from hole in stem

Several reasons cause a faucet to leak from a hole in stem. These include:

1. Faulty O-ring

This is a very common cause especially if you have a cartridge faucet. The cartridge is the valve in the faucet that controls the water flow into the faucet spout.

If it is leaking, then it means that it is loose or worn out. To add to that, a problem with the sink handle can cause a faulty O-ring.

2. Corroded valve seat

The valve seat is the part that connects the faucet to the spout. If the leak is coming from the spout, then the problem may be at the valve seat.

This problem is caused by too much sediment build-up that corrodes the valve seat to cause leakage. 

3. Worn-out washers

If you notice that you have a faucet leak from a hole in stem, worn-out washers can be the cause.

Washers sit against the valve and the friction that occurs in that area can lead to them getting damaged.

To add to that, leaks can happen if the washer is not properly installed or if you bought an oversize or small size washer that does not fit properly. Also, when washers are replaced wrongly they can cause leakages.

4. Worn out seals

Seals are other parts where leaks can occur. When you allow water to accumulate in the seals, the inlet and outlet seal are at risk of corrosion.

Stagnant water around the seals leads to easy corrosion. This is a problem that is mostly overlooked because it is usually hard to ascertain whether there is stagnant water around the seals or not. 

5. Loose Parts

If there are loose parts in the installation of a faucet, then you are likely to deal with leaks within no time. Adjusting rings and packing nuts are likely to get loose over time and can cause leakages.

To prevent leaky faucets, these two parts have to be regularly checked. 

6. Broke parts

If any parts break during the installation process or any other time, leaks can occur in faucets. Any part of the faucet can break and once this happens repair should be done as soon as possible.

Fixing broken parts may require a professional if you are not sure how to go about it.

Why outdoor faucet has holes? How to fix it

Outdoor faucets have holes known as weep holes that prevent water from building up and filling the faucet. This hole is not a defect or an indication that the faucet is damaged.

Fixing a weep hole requires a hole to be drilled at the back of the outdoor faucet. They are small circles with small diameters.

The diameter of the weep holes varies by manufactures. A hole at the back of the faucet sounds like a simple task to do but weep holes should always be installed by professional plumbers.
