The Need of a Water Filtration System in Your Home

The water treatment plants in your local water supply are able to eliminate a good amount of contaminants in order to offer you clean water. Though there are limitations to this as some harmful contaminants can still pass through the filtration process and enter your home plumbing system. 

With the help of water filtration systems, these dangerous contaminants are filtered out in order to purify the water system in your home. This provides you with water that’s safer, cleaner and without the risk of having any potential plumbing and health issues from contaminated water. 

The Right Type of Whole House Water Filter you Need

It’s important to get the right type of water filter for your home to get the best results and prevent any issues in the future. To get the right kind of whole house water filter, you need to take into account the following factors:

  • Water Filter Port Size
  • The Size of the Water Filter
  • Flow rate of the Water Filter
  • Lifespan of the Water Filter

Getting the right type of water filter will also depend on how large your home is and your plumbing system. It’s also a good idea to ask a professional to see what’s the best option before buying a water filtration system to avoid purchasing the wrong one.

Buying a whole house water system that’s too large or too small for your home will affect its overall performance and can even have a huge impact on your electricity bill. 

Can a Whole House Water Filter Affect Water Pressure?

The short answer to this question is yes. Installing a whole house water filter can actually have a huge effect on your overall home water pressure. Though the impact that the water filtration system does on water pressure isn’t as big as it actually seems.

These water systems are designed to properly filter out any harmful contaminants from the outside without causing any convenience to the homeowner. This means that your water pressure will only drop to an insignificant amount, making sure that you won’t notice it at all.

If there’s a chance that you’ve noticed that your water pressure has dropped to a notable amount, then there might probably be a malfunction to the water filter. When this happens, you should contact a plumber to see if there’s anything wrong with your water filter or check if there’s a leak in your plumbing system. 

Factors that can Decrease Your Water Pressure due to a Whole House Water Filter

Improper Water Filter Installation 

If you’ve recently bought and installed a water filter for your home and have noticed that your water pressure suddenly dropped, then there’s a chance that it wasn’t properly installed.

Water filtration systems are designed to function where they wouldn’t cause any problems regarding the flow of water to your house. Any chance of it interrupting your water pressure to a significant amount may mean that there’s an issue with the installation such as a loose pipe or even a leak. 

Hiring a professional to install your whole house water filter is necessary to avoid any possible issues once it starts running. 

Lack of Maintenance

Any type of appliance in your home needs regular maintenance in order for it to run smoothly, this includes your whole house water filter.

You should always check your water filter every 3 to 6 months to see if there are any issues that might cause a probable drop in water pressure. Problems that may arise from leaving your whole house water filter alone can be a malfunction to its regulator or even breakage which can lower its lifespan.

It’s necessary to pay attention to your water filter so that it’s able to perform properly and provide you with clean drinking water and prevent it from affecting your water pressure.

Clogged Water Filter

Having a clogged water filter means that there’s a specific choke point in your water system that restricts the flow of water in your home. This can cause your regular water pressure to drop to a significant amount and even to a point where it’s difficult for the water to reach your shower.

There are two possible culprits for this issue. One is that your water filter cartridge hasn’t been changed, causing it to be filled up with contaminants. It reaches a point where there are too many contaminants for the water to be able to pass through the filter.

The other reason for clogging is that the water filter cartridge isn’t able to handle the amount of contaminants contained in your local water supply. To avoid clogging, it’s necessary to frequently change your cartridge filter or do a water test to see if your water filter is capable enough to filter out the minerals and sediments surrounding your water system.


Installing a whole house water system to your home is more of a “need” than a “want”. The reason for this is that there’s a lot of contaminants that can cause unnecessary health and home risks around your house.

Make sure to find the best type of water filtration system that’s fit for your home and is able to keep almost all of the contaminants that are filled in your local water supply.
