This was my first order from APEC
This was my first order from APEC. Bought a +$400 water filter system. I forgot to apply the 10% new customer discount when I submitted my order so I immediately emailed customer service with the code info. I got an AI automated reply that they wouldn’t do it. Even though the order wouldn’t ship out for another couple days. Disappointing start. Update from 8.3: Thank you for the reply. OK, can you please swap out the subscription for the 10% discount?

Ordered new inline FI-ES-TCR-QC filters for essence 50ES. The price was reasonable for 3. I also installed an Aquatec pump to provide more PSI at the tank and deliver more ice from our ice makers. I ended up order a 60 PSI TSO to increase pressure again and I'm totally happy with the system now.

After 1 1/2 years of using my system…
After 1 1/2 years of using my system all the filter housing had small cracks inside the upper lid near the inlet for the tubing. Originally thought it was gaskets so I changed those. After replacement and still leaking I had to find replacement housings. APEC is way over priced for replacement parts and shipping. I Ultimately had to replace all the housings. The water leak ruined my kitchen Island. I know I did not overtighten when replacing water filter as it closes very snuggly with barely any pressure.In my opinion they are using cheap parts and have a horrible warranty as it will probably fail after a year. When it was not leaking it was great. Very disappointed. Buyer beware.

Dear Ron, Thank you for taking the time to share your feedback. We sincerely apologize for the inconvenience you experienced. Hairline cracks in the filter housings or caps are often the result of sudden or consistently high water pressure entering the system, which can gradually cause plastic fatigue. We recommend checking your water pressure at your earliest convenience to ensure it does not exceed 80 psi, as higher pressure may lead to leaks or damage. We’re always here to help if you encounter any issues with your system. Please feel free to contact us at 800-880-4808. We’re available Monday to Friday from 8 AM to 5 PM Pacific Time, and our team is dedicated to providing you with a 5-star customer service experience. We’ll do everything we can to assist you and ensure you continue to enjoy your RO system. Best Regards, APEC Customer Service
