      Viqua 18 gpm

      Received system fast. Everything was almost ready to use. Even sleeve with o rings were installed. Verified filter, I could see Gary's 'signature' grease to prevent leaks. Just need it to insert UV lamp and connect it to power.

      Thank you Catalin for your purchase and review. We're glad to hear that you're pleased with the system and that it was easy to set up. We hope you enjoy using it!
      We look forward to helping you again soon.
      Take care and stay safe.
