Curated by Workshop Notes · Updated June 2026
Built for homeowners running the Express Water WH100, 200, or 300 series who need to maintain pressure and flow through seasonal sediment spikes. Not for municipal users on lead-specific remediation plans — this shop focuses on heavy-duty sediment and chlorine removal.
Curator's pick: Food Grade Silicone Water O-Ring Lubricant
Most people over-tighten the housings to stop leaks, which ruins the seals; a thin coat of this silicone is the actual trick to getting a watertight seal with just hand-tightening. It makes the next filter swap significantly easier on your back and your wrench.
⚠ Worth knowing: These standard 5-micron filters will struggle and clog prematurely if your well water has high concentrations of fine 'glacial flour' or heavy iron bacteria. If you are replacing filters every two weeks instead of every six months, you need a dedicated backwashing pre-filter, not just larger cartridges.

How to use this together
1
Gather Your Tools and Filters
Before starting, ensure you have the Whole House Water Filter Housing Wrench, Food Grade Silicone Water O-Ring Lubricant, and your selected replacement filters (Sediment Water Filter, Granular Activated Carbon Filter, Activated Carbon Block Filter). Having all items ready prevents interruptions during the process.
2
Shut Off Water Supply & Depressurize
Locate the main water shut-off valve before your whole house filter and turn it off. Open a nearby cold water faucet to relieve system pressure, which will make it easier and safer to unscrew the filter housings. This step is critical to prevent water spills.
3
Replace Filters and Lubricate O-Rings
Using the housing wrench, carefully unscrew each filter housing. Remove the old filters and clean the housings. Apply a thin layer of Food Grade Silicone Water O-Ring Lubricant to new O-rings before placing them back in the grooves, then insert the new Sediment Water Filter, Granular Activated Carbon Filter, and Activated Carbon Block Filter in their respective stages. This lubrication ensures a watertight seal and easier future replacements.
4
Restart System and Check for Leaks
Screw the filter housings back on snugly with the wrench (do not overtighten). Slowly turn the main water supply back on. Allow the system to fill and purge air from any open faucets. Check around each housing for any leaks, addressing them immediately by ensuring O-rings are seated correctly and housings are tight.
