Installing a Whole-House Water Filter
Time Required: Under 2 hours
A whole-house water filter will filter out various water impurities that can potentially get into your household water supply, such as chlorine, fluoride, perchlorates, pesticides, etc. The result is your water will be cleaner and healthier, so you can enjoy great tasting tap water and save money by not having to buy bottled water. Plus, you won’t have to shower or bathe in water that is impure.
This guide details a whole-house filter installation near the water shutoff valve.
- Shut off the water supply to the house.
- Cut into the water supply line near the shutoff valve. Follow the manufacturer’s instructions to ensure you cut away enough pipe to accommodate the filter, the new shutoff valve and any connecting fittings.
- Install a shutoff valve on the house side of the supply line. If you are sweating the valve, remove the insides of the valve before applying heat.
- Dry-fit as many fittings as possible. You may need an adaptor on either side of the filter in order to join your size and type of pipe.
- Mark the final piece for cutting by holding the pipe in place against the end of the shutoff valve.
- Check to see whether your electrical panel has its ground wire attached to the pipe or to a rod driven into the ground. If the ground wire is attached to the pipe, you will need to add a jumper cable to restore an important safety feature that prevents the filter from interrupting the ground path.
- Install grounding clamps on either side of the filter and run a thick wire from clamp to clamp and secure tightly.
