Home Water Filter & Water Softener Maintenance: A Closer Look

January 10, 2025

Whenever our water quality team at Save Home Heat Company speaks with a homeowner about water treatment products that make sense to consider for her or his home, we take the time to review necessary routine maintenance for the system they’re considering, before a purchasing decision is made. Effectiveness, reliability, durability, and maintaining the valuable protections that the product provides – without taking proper care of your water filter or water treatment system, these benefits can’t be enjoyed year after year. This routine maintenance is a commitment you should plan on making when you pull the trigger on a purchase, or your investment will be for naught.

This emphasis on proper routine maintenance also holds for when we service or consult on an existing, permanent home water filter or treatment system. Just like with air filters, furnaces, heat pumps, tankless heaters, and many other products that our team at Save Home Heat installs, routine water filter or related servicing simply should not be ignored.

In this post, we’ll provide an overview of some of the more common water treatment products that we install and service, taking a closer look at their routine maintenance needs.

Water Softeners & Routine Upkeep

As many homeowners are aware, a water softener is a whole-house water treatment system that removes hardness from water entering your home from either a municipal or private well source. The potential negative impacts of hard water are several and varied, from affecting your health, to shortening the life of manual and automatic water valves, a range of appliances (including your water heater), and even the copper piping in your home. Excessively hard water can prove costly if neglected for too long.

Water softeners periodically require the addition of a special salt to the system. Our water quality team at Save Home Heat normally recommends and uses these salts in a pellet form. While there’s plenty of variables that affect how often salt should be added to a softener, every six months, or about twice a year, is fairly common. Many homeowners handle this task, themselves, but we’re glad to help out.

Good Rule of Thumb: Avoid water softener salts that advertise special additives! Talk with our team if you’re considering such a product.

Additional Water Softener Maintenance Considerations

Water softeners typically contain two relatively small water tanks, the softener tank and the salt tank. These tanks do not normally need regular inspecting, cleaning, or replacement. Of course, if you detect leaks or noticeable changes in the performance and effectiveness of your water softener, that’s the time for a closer look by a qualified water quality specialist. In the Denver Metro, Boulder and North area, you can count on our team at Save Home Heat Company to be the right fit your needs.

If your water supply contains chlorine and your softener is 10 years old or more, we recommend speaking with our water quality team about assessing the condition of your system. There may be aging issues with your system relating to salt resin buildup, that you should be aware of.

Reverse Osmosis (RO) Water Filter Maintenance

Commonly known as RO water filters, reverse osmosis water filters are highly effective water filters, capable of removing a broad range of water contaminants. If you’re looking to achieve the purest water, this is the product you want.

Reverse osmosis water filters are often installed in point-of-use locations such as below a kitchen sink, in a master bathroom, or even in a home bar, but they can also be adapted for whole-house applications. In a point-of-use application, an RO filter employs a small side water tap, adjacent to the main faucet.

RO filters contain a number of internal filters that require regular replacement. These include a sediment filter, carbon filters, an RO membrane, and possibly other stage filters such as a remineralizer. Replacing the internal filters should be done approximately once a year, although usage patterns can impact this schedule. It’s not unusual for our team to install or service RO filters that have from 3 to 5 stages.

Virtually all RO water filter systems have a small, pressurized storage tank, which, depending on the size of the tank, is located either under the sink along with the filter or in the mechanical area of the home. The pressure in the RO storage tank should be checked at least once per year, but we recommend checking it more often. In most systems we install and work on, the pressure in the tank should be between approximately 7 and 9 psi (pounds per square inch).

Maintenance for Whole-House Lead, PFAS, and Sediment Filters

Whole-house, inline water filters are designed to remove a wide variety of substances from simple sediment particles to substances that have been identified as posing serious health risks. There’s a wide range of whole-house filters available, and nearly all of them have a replaceable filter cartridge of some sort in common.

Sediment Filters

Simply put, sediment filters remove particles that are suspended in the water, and are rated by the particle size that they are effective capturing. One of the most common types of whole-house, inline sediment filters is designed to remove particles whose size is 5 microns or larger, similar in performance to the prefilters used in products such as RO filters – but without any additional filtration stages. There’s also sediment filters available that can do much heavier lifting, including more effective performance at smaller particle sizes.

Generally speaking, the filter cartridge in most inline sediment filters should be replaced about every 6 months, but of course this can vary depending on water consumption patterns. You should check your filter at least twice a year, or more often if you have a large household that uses lots of water. If you notice dirt collecting at the bottom of the filter sump housing or the filter is considerably darker in color than a new one, it’s time to replace it. Like with many other water filters, they’re designed so that a reasonably handy homeowner should be able to handle the task his or herself. When in doubt, get the advice of a pro like our team at Save Home Heat, serving the Metro Denver and North area for over 45 years.

Lead & PFAS Water Filter Maintenance: The PIONEER Pb

Certain whole-house, inline water filters are designed to take performance to another level, and are highly effective at removing a wide range of water pollutants, beyond basic sediment. These pollutants include lead, PFAS chemicals, certain parasites, chemicals such as chlorine and chloramine, and more.

The PIONEER Pb, from Enpress, is our go-to water filter for removal of many pollutants that pose significant health risks. If you are concerned about lead, PFAS and PFOAs, this is the product our team most often recommends. It is also effective at mitigating the negative side effects of the common municipal water sanitizers, chlorine and chloramine, as well as parasites such as Giardia.

Regarding how often this highly effective water filter’s cartridge should be replaced, it depends to an extent on the primary purpose the filter is being used for, and on how much water has flowed through the unit. The PIONEER Pb has an LED light system that keeps you informed of how much water the unit has processed. When nearing the end of the filter’s effectiveness, the light changes color to yellow (90,000 gallons) or red (100,000 gallons), giving an indication that replacement of the cartridge is recommended by the manufacturer. However, depending on the specific pollutant targeted, the filter may still have effective life remaining. Our Water Quality Association-certified Master Water Specialist would be glad to elaborate. On the average, the PIONEER Pb’s filter is normally replaced every year or two.

Carbon Filters

Carbon water filters are available for either whole-home or point-of-use applications. These filters mitigate the potential undesirable effects of the sanitizers chlorine and chloramine, as well as other substances such as VOCs, organic pesticides, and potential sanitizer byproducts. They’re also effective at addressing taste and smell issues.

In homes that are served by a municipal water system, carbon water filters should be checked annually by testing the home’s water for chlorine. If chlorine levels are not at or very close to zero, it’s time to replace the filter element. Depending on the design of the carbon filter, this could be a very simple procedure, or it might require the assistance of a water quality professional like our team at Save Home Heat Company.

UV Treatment Filters

Ultraviolet treatment water filters, also known as UV water purifiers, are often employed where unhealthy bacteria in a water supply has been identified. These types of filters are most commonly used in rural and mountain areas where a private well is in use, however, they may also be recommended in urban areas where unusual conditions are present.

Virtually all manufacturers of the ultraviolet bulbs used in these products recommend bulb replacement every 10,000 hours. Since these water treatment products are powered-up 24/7, and considering that one year equals approximately 8,760 hours, replacing the bulb annually, or nearly so, is the best way to ensure full effectiveness of your UV water purifier. When replacing the bulb assembly, it’s important to check the clear sleeve that houses the UV bulb to see if it needs a light cleaning. UV light must be able to bath the water that flows by, and a clean, clear sleeve is important. Of course, our team does not encourage homeowners to perform this procedure unless they are fully versed and comfortable with the procedure – this goes for any water filters mentioned in this post!
