Installing your whole house water filter
#1. Use buckets and trays to catch leaks
Turning off your water at the main shut-off and draining your system before beginning installation is a must. Use the lowest faucet in your home to let water and pressure escape.
Even after this, however, small leaks are likely to occur as you set things up and check everything is correctly aligned. Protect your floor and maintain a safe working environment by placing buckets or trays underneath major connections and places where filter components are threaded together.
(Extra tip: leave the nearest faucet to the filter open during installation to allow any residual water or air to escape.)
#2. Leave room for a sediment filter and conditioner
Almost everyone who needs a whole-house filter for their well will also want a sediment filter to remove small particles before the water reaches the more delicate filter elements. Using a sediment filter will contribute to water purity and prolong the lifespan of expensive filter stages.
Because groundwater is naturally harder than surface water, many well owners also add a well water softener or conditioner alongside their filter system. So if your system doesn’t already include these things, try to leave room for them in case you decide to add them at a later point.
Remember that you’ll need room to access your filter periodically to check for leaks and change filter cartridges. Try to find a spot with sufficient space along the main water line before it branches to the various appliances in your home, and also allows for mounting the system to a wall or floor joist.
#3. Include a bypass valve
Installing your filter and/or softener on an additional line that can be bypassed with valves gives you the option to disconnect your filter without turning off the water supply to the rest of your home.
A bypass valve can make the process of changing filter cartridges less tiresome—especially if you go the extra mile and also install shut-offs between each filter stage so that you can isolate individual parts of your system.
Sediment filter screens often need to be cleaned or switched out every few months, while carbon filters require annual or biannual replacement.
#4. Flushing and checking for leaks
When your new filter system is connected, turn the water back on to flush the system out and check for any leaks.
Sometimes, slightly dripping from the filter casings compression fittings can be simply fixed with careful tightening. With more significant leaks, components may need to be taken apart and reconnected with great precisions.
Popular hacks for solving leaks include wrapping Teflon tape around the threads, greasing them, or using extra O rings.
Flushing your filter system will help to clear any dust or residue from manufacturing and installation, as well as prime the filter cartridges. Carbon filters, in particular, can require extensive flushing and may produce small pieces of black charcoal for hours or days, as air in the carbon block is replaced with water. This is normal and safe.
Once water is running clean and clear without air bubbles, your system should be running at full efficiency.
#5. Don’t be shy to call in a professional
Many people decide against DIY installation and instead reach out to a professional to fit their new filter system. Some manufacturers and suppliers will also offer installation services when you purchase the system, and many plumbing companies have a filter fitting service.
Always use licensed professionals when installing filters, drilling wells, servicing heaters, or commissioning any other plumbing jobs on your property.
