A: The Canyon Matrix accommodates pumps up to 2500 GPH. Choose your pump based on your waterfall height and desired flow rate. For most backyard waterfalls, pumps in the 1000-2000 GPH range work well. Q: Do I need to purchase a pump separately? A: Yes. The Canyon Matrix is a pump vault that houses your pump—the pump itself is sold separately. This allows you to select the pump that best matches your specific requirements. Q: How does the autofill feature work? A: The Canyon Matrix includes an autofill spinweld connection point. Add the optional autofill kit (PB1342, sold separately) to automatically maintain proper water levels as water evaporates, reducing maintenance and preventing pump damage. Q: Can I use this for a pondless waterfall? A: Absolutely. The Canyon Matrix is ideal for pondless waterfall installations. It serves as the underground reservoir that collects water and houses the pump. Cover the area with decorative rock for a beautiful, low-maintenance water feature. Q: How do I access the pump for maintenance? A: The Canyon Matrix features a pump access lid that allows easy access to the pump chamber. Simply remove the lid to service the pump or perform routine maintenance without excavating the vault. Q: What does the lifetime warranty cover? A: Blue Thumb's lifetime manufacturer's warranty covers defects in materials and workmanship for the Canyon Matrix vault. Refer to warranty documentation for complete terms and conditions. Q: How much water does this hold and why does that matter? A: The Canyon Matrix holds 21 gallons. This capacity provides reserve water for your waterfall system, reduces refilling frequency, and helps prevent the pump from running dry during evaporation or splashing. Q: Can I install this myself? A: Many DIY enthusiasts successfully install the Canyon Matrix using the straightforward design. However, professional installation is recommended if you're unfamiliar with waterfall construction, pump selection, or landscape excavation. Q: What size hose does the passthrough accommodate? A: The Canyon Matrix has a 2" passthrough hole designed for 1.5" flex hose, which is the standard size for most waterfall and stream applications. Q: Do I need to cover this with anything? A: Yes. The Canyon Matrix is designed to be buried and covered with decorative rock, gravel, or landscape material. This conceals the vault and creates the natural appearance of a waterfall or stream while maintaining access to the pump lid.
