The Everpure EV962716 (7FS-BW) is the replacement pre-treatment cartridge for the Everpure MRS-600HE II reverse osmosis system. It reduces chlorine taste and odor, filters particles, and controls scale ahead of the RO membrane. It’s designed for owners and facility managers who keep that system in service. On-time Everpure EV962716 filter replacement keeps that protection in place.
Below, you'll find when to replace it, how to confirm it's the right cartridge for your system, and a full walkthrough of the replacement itself.
Why & When You Should Replace the Filter
Everpure EV962716 filter replacement keeps three pre-treatment functions working for your RO system. The cartridge's carbon filter reduces chlorine taste and odor, it filters dirt and particles as small as 5 microns, and it controls scale formation to help extend membrane life. All three depend on the cartridge's rated capacity, which is used up as water runs through it. A cartridge past that point gives the RO membrane less of the protection it relies on.
Everpure specifies changing the cartridge on a regular one-year preventative maintenance program. It should be changed sooner if it reaches its 30,000-gallon (113,562 L) rated capacity or if pressure falls below 10 psi (0.7 bar), whichever comes first. Signs it's time:
- The cartridge has reached 30,000 gallons
- It's been a year since the last change
- Pressure has fallen below 10 psi

Step-by-Step Replacement Guide
Signs Your New Filter Is Not Installed Correctly
If something seems off after a replacement, check for these common installation issues. For any of them, shut off the water and release system pressure (Steps 1–2 above) before reseating the cartridge.
- Leaking at the filter head or fittings: The cartridge may not be fully seated in the head. Remove it, then align it and twist it back in until it's secure. If the leak is at a fitting, inspect the fitting and tubing and reseat the connection.
- Cartridge not fully seated or not hanging vertically: The cartridge should hang straight down with the head above it. If it sits crooked or feels loose, it hasn't been twisted all the way in. Reseat it until it's secure.
- Restricted flow or low pressure: Confirm the water supply is fully back on and the cartridge is seated properly. If pressure stays low, see the Why & When section, since low pressure is also a replacement trigger.
- Air or carbon particles that persist after the flush: Some air and fine carbon particles are normal at first. If they're still showing up after the flush, reseat the cartridge and flush again. See What to Expect After Installing the New Filter below.
What to Expect After Installing the New Filter
Flush the new EV962716 by running water through it at full flow for 5 minutes. Everpure calls for this flush at initial installation and at every cartridge change. Here's what's normal during and right after the flush:
- Air in the line: Trapped air purges out as the flush runs.
- Fine carbon particles: Loose carbon fines from the new cartridge are expected at first and are cleared by the flush.
- Air and particles clear: Once the 5-minute flush is done, the water should run free of air and carbon particles.
- Quick final check: Confirm steady flow, no leaks at the filter head or fittings, and pressure within the operating range listed in the Prepare section.
If air or carbon particles are still showing after the flush, recheck that the cartridge is fully seated and that there are no leaks at the head or fittings. Then flush again at full flow for another 5 minutes.

Maintenance Tips for Longer Filter Life
A few simple habits keep each EV962716 cartridge doing its job for its full service life:
- Follow the annual replacement program: Keep to the preventative maintenance schedule covered in the Why & When section above.
- Don't run past capacity or low pressure: Once the cartridge reaches its rated capacity or pressure drops below the threshold in the Why & When section, replace it rather than keep it in service.
- Inspect fittings and tubing for leaks: Check them periodically and reseat any connection that isn't tight.
- Clean the exterior gently: Use a mild, non-abrasive cleaner on exterior surfaces.
- Stay within the operating limits: Keep water pressure and temperature within the ranges listed in the Prepare Your Replacement section.
- Keep the RO membrane protected: The cartridge controls scale formation ahead of the membrane, so keeping it on schedule helps extend membrane life.

Troubleshooting & FAQ
The new EV962716 cartridge is leaking. What's wrong?
The cartridge usually isn't fully seated in the head, or a fitting has worked loose. Shut off the water and release system pressure, then reseat the cartridge until it's secure. Inspect the fittings and tubing too, and reseat any loose connection.
The used cartridge is hard to remove.
Make sure the water supply is off and system pressure has been released before you try to remove it (see Steps 1–2 in the Step-by-Step Replacement Guide above). Then twist it out of the head, following the instructions packed with the new cartridge.
Flow is slow after replacing the EV962716 cartridge.
Check that the water supply is fully back on, the cartridge is seated properly, and the full flush has been completed (see What to Expect After Installing the New Filter above). If slow flow or low pressure shows up once the cartridge has been in service a while, it may be due for replacement. See the Why & When section for the schedule.
How do I confirm I'm ordering the right cartridge?
Match the model on your used cartridge and your system against EV962716 / 7FS-BW. See Verify Filter & System Compatibility in the Prepare section above for the full details.
