Why Is My Outside Tap Not Working? How To Fix It?

Outside taps, also referred to as faucets, are devices used to control the flow of liquids, especially water from a pipe or the primary source. Most outside taps are used to provide water supply for use around the homestead for domestic purposes. However, it is exposed to several risks outside the house, which may lead to its failure.

These are risks that many people have come to terms with after identifying the problem and solution.

Reasons Why Your Outside Tap Is Not Working


This is usually one of the many reasons why the outside tap may not be producing water. Blockages are in the form of sediments that have built up, stopping the flow of water by causing clogging in pipes. This is due to metal deposits in the main source of water, debris, and even rust. 

When these particles clog in the pipes, they end up blocking the pipe conveying water to the outside tap.

How To Fix It?

  • For a blocked pipe, it would be advisable to call a plumber. Plumbers conduct a drain camera inspection, determining the cause of the blockages and repairing it.
  • One can also use a high-pressure jet to clear up the dirt causing the blockages.
  • Sometimes the tap is the problem; therefore, replacing the tap with a new one is the best option in the long run.

Corrosion Of The Washer

Corrosion occurs when oxidation takes place in the interior of the pipe walls. This happens when the tap has not been used in a while, leading to the washer becoming welded/corroded. The seat is the main place where corrosion occurs. It seals the tap and stops water pressure from flowing. It first reduces the water to trickles before stopping the flow completely.

You may also identify this problem by noticing chatters from the tap. When the tap starts producing unfamiliar noises such as chattering, it signifies a damaged washer.

Possible Fixing Ways

  • Get a new tap/washer since the old one is corroded and ensure proper installation for efficient results.


Leakages divert water away from your tap and prevent it from reaching the endpoint. Some small holes and cracks in your pipes could be causing this leakage by enabling water to escape to the ground before it reaches your faucet. This causes the tap not to work as effectively as it should.

The pipes could leak and create low pressure due to constant drips and dents. Therefore, in the long run, this causes the water flow to stop. Leaks are the most common cause of failure of tap water coming out.

How To Fix?

  • Carry out pipe fixing by fixing the dents or entirely replacing the pipes with new ones if the dents are too big to be fixed.
  • If the leaks are coming from the primary source of water, the main tank may need to be drained and fixed to stop the leaking.

Low Pressure From The Main Water Source

This is the kind of pressure that cannot pump enough water from the main tank through other taps. Hence no water comes out of the taps. For instance, if there has been no rain, the main tank taps water from rainwater.

This pressure becomes too low to convey water into the pipes, which is another reason outside taps are not working. The primary water source becomes the reason for low pressure. Another reason why there is low pressure from the primary water source could be a broken pressure regulator

Pressure regulators are designed to maintain the outlet pressure despite any internal fluctuations in the inlet pressure, and if the pressure regulator is broken, it won’t pump water out to the faucet.

How To Fix It?

  • Regularly check on your main tank to ensure that there is enough water to pump through the pipes to the taps.
  • Refill your tank with water or wait until the rains are back and check if the taps will run water normally.
  • Check if the main water valve is closed, which could be why there’s no water coming out of your faucet.
  • Adjust the pressure regulator
  • In the case of a faulty regulating device, contact a plumber to get it fixed or replaced.

Jammed And Wrecked Valve

Most outside water taps are simply installed with a one-way double check valve inside them. This valve jams sometimes, and hence no water comes out of the tap. These valves get damaged, especially during the cold, harsh weather.

The cold weather might have exerted very high pressure along the supply pipe due to freezing and the expanding ice. This will automatically lead to jammed-up valves, which can eventually break valves.

Possible Fixing Ways

  • This might seem to be a repeated issue in cold weather. There is a way of unfreezing, which is using a hairdryer on the pipe.
  • One can also get a double NRV (non-return valve) fitted and ensure proper installation.
  • Install a winter insulation hood on the outside tap to avoid such repeated occurrences.
  • Open up the tap for the winter to ensure no back-pressure builds up.


Rust is one main reason why taps will suddenly stop working. Generally, you may notice rust on the outside of the tap and think that the inside is okay. However, plumbers have concluded that rust from the outside shows that it is present in the interior too and will just continue to spread if you don’t act quickly.

This mainly occurs on metals when they come in touch with water. Moreover, they rust after a long time of use and exposure to the sun. This rust leads to wearing out and tearing, leading to blockage.

How To Fix?

  • Rust is permanent; therefore, the best way to fix this problem is by replacing your tap with a new one. By doing so, the tap will adequately work if it is the issue.

Other Taps

This is another critical thing to check. If there are several taps in your household, you should check if water is properly flowing through them. This is in a case whereby they are newly installed, and only the outside tap is not working.

If all the other taps are working, then it could be an issue of the tap being faulty, but if none of the taps are working, then the problem could be more prominent.

How To Fix?

  • This is quite unfortunate as one will have to replace the faulty tap altogether. In most cases, call the plumber who installed the other taps to replace them or your supplier.


Outside water taps have eased the work while gardening or taking care of flowers around houses. You do not have to carry around watering and jerry cans to water your garden tap. You only need to connect the water pipes to the outsi
