How To Fix A Leaking Water Filter?

Leaking water filters often present a problem for homeowners. There can be several reasons for water leaking.  Fortunately, with the right knowledge and tools, you can repair leaking water filters and save money on professional repairs.

What Are Common Signs Of A Leaking Water Filter

• Dripping sounds: If your water filter is leaking, you might be able to hear it. Listen for a steady dripping sound from the filter or around the area where the filter connects to your plumbing.
• Water spots: If you have noticed water spots around or underneath the filter, the filter is likely starting to leak. If left unchecked, this can lead to water damage and further problems in the future.
• Changes in water pressure: A common cause of leaking water filters is a change in the local water pressure. This can cause a sudden increase or decrease in pressure, which could lead to leaks around the filter’s seals.
• Unpleasant taste or smell of water: You may also notice your water’s unpleasant taste or smell after it passes through the filter. This is a sign of a blockage in the filter caused by accumulated debris and dirt that must be removed.
• Visible leakage: If you can see water dripping from the connection, it is a sign that the filter needs to be replaced.

Causes Of Water Filter Leakages

• Loose fittings: If the water filters components, such as hoses, tubes, or connections, are not tightened properly, this can cause a leak. Over time fittings may come loose due to regular use and vibrations.
• Cracked filter housing: If the housing of your water filter is cracked, this can lead to water leaking out.

  

• Faulty O-rings or seals: O-rings and seals are common culprits for leaking water filters. The O-ring is a rubber ring between the filter head and the housing cap. It is designed to provide a seal around the connection area, preventing water from leaking out.

  

• Clogged or damaged tubes: If there is a hole or tear in the tubes connected to the water filter, then this could be the cause of your leaking water filter.
• Worn-out filter cartridges: A worn-out filter cartridge is the most common cause of a leaking water filter. If your filter’s housing is not cracked, the issue may be with the cartridge itself. Check that the seal around your filter cartridge is still intact, and if it has become worn down or damaged, it should be replaced.
• Sediment Buildup On O-ring Channel: Sediment building up in the O-ring channel is another common cause of leaking water filters. The O-ring is a rubber ring that seals the filter housing, and if it gets clogged with dirt or debris over time, this can prevent the seal from forming properly and lead to leaks.
• Incorrect Installation Or Incompatible Adapters: An incorrect installation or incompatible adapters are other common causes of a leaking water filter. A misaligned adapter or an adapter with the wrong diameter may not fit properly and lead to a leak in your water filter. If you recently changed your water filter, it is worth double-checking that the adapters have been installed correctly and are compatible with your filter.
• Over-Tightened Filter Housing: If the filter housing is tightened too much, it can cause a leak. To fix this issue, loosen the filter housing slightly until the water stops leaking.
• Hot Water Damage: If the leaking water filter is connected to a water heater, you may be dealing with hot water damage. When hot water comes into contact with metal or other materials, it can cause corrosion and oxidation. If left unchecked, this can lead to serious property damage and create an unsafe environment.

How To Fix A Leaking Water Filter?

Shut Off The Water: Before starting any repair work, shutting off the water running through the filter is important. This will help ensure that no water damage occurs while you fix it.

Release The Water Pressure: If you have a water filter with a separate faucet, release any built-up pressure. If there is no separate faucet, open all the taps in your house and let them run until they stop dripping. This should allow most of the pressure to be released from the filter.

Remove The Water Filter Housing Bottom: The first step in fixing a leaking water filter is to remove the housing bottom. This process can vary depending on your specific model and brand of water filter but typically involves undoing two screws at the unit’s base and then gently sliding the bottom off. If you have been experiencing a nasty leak, checking for any cracks or visible damage to the housing bottom before moving on is important.

Check The Filter Housing O Ring: check the filter housing O ring for any signs of damage, tears or cracks. If you find the O ring damaged, replace it with a new one. Make sure to use the same type and size of O-ring as the old one.

Lubricate Filter Housing O Ring: If the leaking comes from the filter housing, the O ring likely needs to be lubricated. Check your user manual for instructions on removing and lubricating the O ring. Make sure you use food-grade silicone grease or vaseline with no additives. Wipe off any excess before re-installing.

How To Properly Change Your Water Filter To Prevent Leaks?

Step 1: Locate the water filter unit near where the water line enters your home.

Step 2: Unscrew the filter cap and remove the old water filter from its slot.

Step 3: Clean any debris inside the housing, and ensure it is free of rust or other discolouration caused by leaking water.

Step 4: Insert the new filter in the slot, paying attention to any arrows or other markings that indicate the proper installation position.

Step 5: Secure the cap back on tightly, ensuring it is sealed properly with no gaps between the cap’s edges and housing.

Step 6: Turn on your cold water line to flush out any dirt/debris that may have been left behind in the lines.

Step 7: Check for any leaks from the filter housing and tighten if needed, or replace them with a new one if the leak persists.

What If My Water Filter Still Leaks After I Have Cleaned It?

If your water filter is still leaking after you have cleaned it, try replacing the seals. The seals can become brittle or worn over time and may need to be replaced to stop the leaking. You will likely need a spanner or similar tool to loosen and remove the existing seals before fitting new ones. Ensure you buy seals compatible with your water filter, as using the wrong type may lead to further leaks or damage.

How To Prevent Leaks In Under-Sink Water Filters

• Use High-Quality Filters: A high-quality filter is the best way to avoid leaks in an under-stalled correctly. If the filter is of low quality, it may not be able to withstand normal water pressure and could cause a leak.
• Clean the O-Rings Regularly: O-rings are the rubber seals around the filter connections. If they become dirty or harden over time, they can create a gap allowing water to seep through. To ensure your connections stay leak-proof, clean the O-rings regularly with warm soapy water and dry them thoroughly before reassembling the filter.
• Don’t Over-Tighten the Filter Housings: When installing a filter, it is important not to over-tighten the filter housing. If you screw the housing down too tightly, it can cause the seals or gaskets to be damaged and create leaks. You should only tighten the housing until it is snug, no more than one full turn afterwards.
• Check your System Regularly: A leaking water filter likely needs more than one repair fix. To ensure that your water filtering system remains in good working condition, it is important to check the connections regularly. Ensure all components are properly tightened and that nothing appears loose or damaged. If any part of the system looks like it is not functioning correctly, then take the time to repair or replace it as soon as possible.
