Watch original on Youtube

This bundle provides the essential components and tools for installing a whole-house water filtration system, as demonstrated by This Old House. It is designed for homeowners and DIYers who want to improve their water quality throughout their home. The selection covers the main filter unit, necessary plumbing fittings, shut-off valves, and specialized tools for assembly and maintenance.

Curated by The Shelf Curator · Updated June 2026

Built for homeowners or facility managers who need a comprehensive hardware package for permanent inline sediment and chemical filtration. Not for renters or temporary setups — this shop focuses on sweat-free, high-pressure copper plumbing integration.

Curator's pick: Lead-Free Brass Full Port Ball Valve

This is the most critical failure point in any filtration loop, and a full port brass design ensures zero flow restriction while providing a reliable hard shut-off for annual filter housing maintenance. Unlike standard gate valves, the quarter-turn actuation and heavy-duty brass construction prevent seizing in high-mineral environments.

⚠ Worth knowing: The ProPress fittings included here require a specialized hydraulic press tool for installation; manual crimpers or standard solder methods will not work with these specific elbows. If the project lacks access to a press tool, traditional sweat fittings are the necessary alternative to prevent high-pressure leaks at the filter inlet.

How to use this together

  1. 1

    Plan Your Installation & Shut Off Water

    Before beginning, identify the main water line entry point into your home and the best location for your Heavy Duty Whole House Water Filtration System. Ensure you have enough space for the filter and access for future maintenance. Critically, turn off your home's main water supply at the shut-off valve and drain the pipes by opening faucets to relieve pressure. This prevents flooding and injury during the installation process.

  2. 2

    Cut Pipes & Install Bypass Valves

    Using the Ridgid 2-in-1 Close Quarters Tubing Cutter, make precise cuts in your main water line to accommodate the filter system and bypass. Install the Lead-Free Brass Full Port Ball Valve on either side of where the filter will go, and one on a bypass loop. The ball valves allow you to isolate the filter for maintenance without shutting off all water to your home, and the bypass ensures water flow during filter changes.

  3. 3

    Assemble Filter Housing & Connections

    Mount the Heavy Duty Whole House Water Filtration System securely to a wall or stable surface. Begin connecting your plumbing. For copper pipes, use ProPress Copper Press Fitting Elbows for secure, solder-free joints where turns are needed. Apply Teflon Pipe Thread Sealant Tape to all threaded connections to ensure a watertight seal, preventing leaks that could compromise your system's integrity or damage your home.

  4. 4

    Check for Leaks & Restore Water

    Once all connections are made and the filter is securely in place, slowly turn your main water supply back on. Inspect all connections, especially those with Teflon tape and ProPress fittings, for any signs of leakage. Address any leaks immediately. Gradually open faucets in your home to purge air from the system. Finally, use the Universal Filter Housing Wrench to ensure the filter housing is tightened properly, but do not overtighten.
