Once you get your unit, you’ll need to install it. This can be accomplished with basic plumbing knowledge, but it will require you to cut the copper supply lines and install the appropriate fittings. If you don’t feel comfortable with this kind of work, it’s recommended to hire a pro so you can ensure it’s done properly. Wondering how to install a whole-house water filter on your well?
Installation instructions vary slightly depending on your setup, but here are some things to keep in mind:
Installation Location – You’ll want to install your setup where the water supply first enters your home. This may be in your utility room, basement, or wherever your water heater/storage tanks are located. Unlike other filters, whole-house setups generally won’t install under your kitchen sink, and they require a good amount of space. Make sure to measure your installation area to ensure it will fit properly.
Prefilter – You’ll want to consider if your filter setup already includes a prefilter/sediment filter, or if you’ll want to purchase one separately. Prefilters will remove some heavy sediment and minerals, but won’t actually purify your water. Using a prefilter can help to reduce the workload on your main filter unit. It’s particularly important if you live somewhere with very hard water.
Plumbing Skills – Before you get started, think about your experience with plumbing and your general comfort level when it comes to handyman skills. If you have no experience with plumbing, it may be worthwhile to hire this job out. Whole-house water filter installation costs vary significantly, but you can expect to spend at least a few hundred dollars for an installation.
Water Quality – Well water can be very clean and high-quality – but it can also become contaminated quite easily. Environmental factors around the well can easily contribute to contamination. Lawn treatment chemicals, pesticides, spilled fuel, and other contaminants can sometimes seep into well water from nearby sources. It’s important to maintain healthy water quality in your well, and a filter can help.
Safety – When you draw from a private well, you are solely responsible for the safety of that well water. There are no government regulations or treatment practices in place to protect your water supply. There are a lot of very dangerous potential well water contaminants to be concerned about – most of which can be addressed using a filter.
Testing – When drawing from a private well, it’s important to conduct routine tests on your water supply. The EPA recommends testing at least once per year, in order to gauge the safety and quality of your drinking water.
Hard Water – Wells are also prone to having hard water, which is water rich in dissolved minerals. While not harmful to human health, hard water can cause stains on showers and sinks, and can also damage appliances. Some of the best whole house water filter for well water options also soften water.
Well-Specific – We chose models that were specifically designed for use with well water. There are actually surprisingly few well-specific models out there, as the majority are made for city use. We found the best options on the market that are actually intended for use with private well water.
Filtration Technology – We of course looked at the actual filtration technology of each unit. It’s important to have an effective filter that can safely remove harmful contaminants.
Flow Rate – Since these products need to supply water to your whole house, the best whole house water filter for well water needs to have a high flow rate. We chose models with adequate flow rates to supply an entire average-sized home with filtered water.
Value – There’s quite a range of prices in the industry, and even products on this list range from less than $400 to over $1800. Instead of looking solely at the cost, we analyzed the actual value each product offered, compared to its upfront and ongoing costs.
