Step-by-Step Guide On How To Fix A Leaking Water Filter.

Step 1: Look For Leaks On The Exterior 

Before you plan on removing the entire house water filter housing, locate where exactly on top it is leaking.

Is it leaking from the threads?

Are there any cracks? 

Is the pipe leaking, or is the pipe damaged?

If there is some noticeable damage/ crack along with the housing, you are most pretty lucky cause all you have to do is replace the filter instead of repairing the whole thing.

Step 2: Remove Whole House Filter Housing 

If you do not see a visible leak in the whole house filter housing, the time has come to remove the filter body so you can investigate it properly. 

The first and foremost step always is to shut down the water supply. After you have shut off the water, you can press the pressure release button on the top of the whole house filter.

And afterward, we suggest you open a faucet and drain all the water out of the filter. This way, when you remove the whole house water filter, you will not have to worry about your home flooding.

In case you have an ‘outlet’ shutoff valve, which is on the supply side of the whole house water filter, turn this valve off to avoid flooding.

Furthermore, before you remove the housing, it is a brilliant idea to put a container under the filter to get any water.

Step 3: Check the Rubber O-Ring 

The moment when you remove the canister, very carefully remove the O-ring to check it for any potential damage and which might be the source of the leak. You can pry out the O-ring with a screwdriver or even tap the canister upside down, and the rubber ring might drop. 

Clean the O-ring, and see if for scratches or damage. Is the O-ring still adaptable and damage-free? In case there is any damage to the O-ring, it needs to be replaced. 

Furthermore, before re-installing the O-ring, it must be covered with a silicone lubricant to give it a robust seal. Also, make sure to clean the O-ring break on the canister in case it is dirty or has any debris. 

Step 4: Examine The Housing Interior and Threads 

After you are done assessing the O-ring, we suggest that you examine the housing interior and the threads. If you have a torch or a flashlight, it will be helpful to to notice the defects. 

You might want to clean the interior of the canister and threads first so you can carefully see any hairline damages. Furthermore, remember to examine the threads on the housing. Also, do not just examine the threads on the housing but also where the housing is screwed onto and the top of the filter. And, in case you notice any breaking or damage on the housing or the threads, we strongly suggest replacing the whole filter housing than trying to fix it.

Step 5: Re-install The Whole House Filter Housing 

If you could not track down any noticeable deformities or damage, the leaking may simply be an aftereffect of a poorly installed O-ring, or the canister was not tight enough. 

After re-installing the filter into the housing, ensure that the filter is placed appropriately on the bottom (the areola should fit perfectly inside the lower part of the filter). Moreover, use the filter wrench to fix the canister back onto the system.

Step 6: Turn On Water and Inspect For Leaks 

Once you are all set with the above-given steps, now is the time to turn on the water supply of your filter. 

If your filter has a pressure release button, press the button. 

Also, if you have an outlet shutoff valve (supply side), turn it on. We would like to emphasize turning the water supply on gradually since, in case that you turn on the water supply too fast, it can cause a leak. 

Step 6: Turn On Water and Inspect For Leaks 

Once you are all set with the above-given steps, now is the time to turn on the water supply of your filter. 

If your filter has a pressure release button, press the button. 

Also, if you have an outlet shutoff valve (supply side), turn it on. We would like to emphasize gradually turning the water supply on since if you turn on the water supply too fast, it can cause a leak. 

Now very carefully assess the top of the filter using a flashlight. Mostly, lubing up the O-ring and re-fixing the canister should have stopped the leak.
