The fastest way to swap filters on a Rhodi 0 flow during a job

|Mohammed Sohag

The fastest way to swap filters on a Rhodi 0 Flow during a job is to maintain a "pre-loaded" service kit in your van including a universal filter wrench and spare 10-inch sediment and carbon blocks. Because the Rhodi 0 Flow utilizes non-proprietary housings, a swap takes less than 5 minutes. Regularly replacing pre-filters every 2–4 months prevents unexpected pressure drops, ensuring your system maintains its consistent 0.5 GPM flow rate. By following the 10 ppm rule for resin, you can plan swaps between jobs rather than interrupting your workflow on a commercial site.

Downtime is a Profit Killer

When you’re in the middle of a $1,000 commercial glass contract, the last thing you want is a clogged filter slowing your flow. If your water-fed pole starts "sputtering" or your height reach drops, you likely have a saturated sediment filter.

Because the Rhodi 0 Flow stands 49 inches tall and is built with a stable 50 lb steel frame, it’s designed for easy access. You don't need to take the whole system apart to get to the "guts." Here is the 5-minute professional "Pit Stop" method.

The 5-Minute "Pit Stop" Method

Step 1: The Pressure Bleed

Never try to unscrew a housing while the system is pressurized.

  • Turn off the water at the tap.
  • Open your brush valve or the waste valve to let the remaining pressure out.
  • Pro-Tip: If the housing is hard to turn, it’s because there is still internal pressure. Bleed it dry first.

Step 2: The Quick-Spin Swap

Using your universal filter wrench (which should be provided withyour Rhodi 0 Flow system), unscrew the housing.

  • Drop the old filter.
  • Quick-rinse the housing with a splash of water to remove any trapped silt.
  • Slide in the new 10-inch filter. We use non-proprietary sizes so you can grab these from any local supplier or from us in 2026.

Step 3: Lube and Seat

Before screwing the housing back on, check the black O-ring. A dry O-ring is the #1 cause of leaks that drop your flow rate below 0.5 GPM.

  • Apply a tiny amount of silicone lubricant to the O-ring.
  • Hand-tighten the housing, then give it a 1/8th turn with the wrench. Do not over-tighten.

Plan Your Swaps: The 10 ppm Strategy

The fastest swap is the one you do before the job starts.

  • The 10 ppm Rule: Monitor your final output. If you’re at 8 ppm at the end of Monday, don't start a massive commercial job on Tuesday expecting it to last. Swap your resin in the garage Monday night.
  • Carbon Defense: Remember, your carbon filter needs a swap every 2–4 months to protect your RO membrane. Since the membrane is the "heart" of your Lifetime Warranty system, don't rush this swap. Do it carefully to ensure no chlorine reaches the Stage 3 membrane.

The "Emergency Kit" Checklist for Your Van

To ensure you never lose a day of work, keep these four items in a dedicated "Rhodi Box" in your rig:

  1. Filter Wrench: The universal tool for 10-inch housings.
  2. Spare O-Rings: Cheap insurance against a pinched seal.
  3. 2x Sediment Filters: These clog the fastest in old cities.
  4. TDS Meter: To ensure you are hitting that 0.5 GPM at 0-10 ppm standard.

The Verdict: Built for Speed

We built the Rhodi 0 Flow because we hate proprietary systems that require a PhD and a special toolset to maintain. At 50 lbs of powder-coated steel, this system is a tank, but its maintenance is as simple as it gets.

Minimize your downtime and maximize your glass time.
