How-To & Support: Maintenance and Troubleshooting Tips
Here are answers to common questions that help simplify water filter troubleshooting and care:
How often should I change my whole-house filters?
As a general rule, replace your filters every 6–12 months, depending on your household’s water quality and usage. Houses with poorer water quality or higher water consumption may require more frequent changes.
How do I know if my O-ring needs to be replaced?
Look for signs such as cracks, flattening, dryness, or a poor seal. If you notice water leakage or resistance when sealing the housing, it’s time for a new O-ring.
How can I troubleshoot a leak?
First, check the O-ring for wear or improper placement. Ensure the fittings are tightened correctly and that PVC connections are secure. A simple adjustment or replacement often solves the issue.

FAQ
Can I use a universal replacement part with my APEC Water system?
While some home water filtration system parts are universal, we recommend using APEC water filters whenever possible. They’re designed to ensure a proper fit and reliable performance. Using off-brand components may cause leaks or reduce efficiency.
I have a leak coming from my filter housing. What should I check?
Start with the O-ring, ensure it’s clean, properly seated, and not cracked or worn. Also, check that the housing is tightened securely using a filter wrench, and inspect PVC fittings for loose or damaged connections.
What should I do if my water tastes or smells bad even after a filter change?
This could indicate that your filter needs to be flushed after installation, or that other filters in your whole house water filter system are due for replacement. If the issue persists, check your water source for changes in quality and consider upgrading filter stages.
How do I install a new O-ring on my filter housing?
First, remove the old O-ring and clean the groove on the housing. Apply a light layer of food-grade silicone lubricant, then carefully place the new O-ring in the groove. Ensure it sits flat and even before tightening the housing.
What is a mounting bracket used for, and how do I install it?
A mounting bracket secures your filter housing to a wall or frame, preventing strain on plumbing connections. To install, attach the bracket to a sturdy surface with screws, then fit the filter housing into place before connecting the plumbing.
How do I know when it's time to replace my water filter?
Most whole-house filters should generally be replaced every 6 -12 months, but timing depends on your water quality and usage. Signs it’s time for replacement include reduced water pressure, bad taste or odor, or visible dirt in the filter.
Can I replace my water filters myself, or do I need a professional?
Most parts, like filters, O-rings, and accessories, are designed for DIY repair or replacement and can be replaced at home with simple tools.
For more complex plumbing changes or if you’re unsure about compatibility, professional installation may be helpful.
