Undersink Delphi Water Ionizer help
Practical guidance for choosing and installing your Undersink Delphi Water Ionizer.
The main ionizer and filtration components are installed inside the sink cabinet and connected to a dedicated ionizer faucet at the sink. Installation requires suitable cabinet space, a water connection, power, and an opening for the faucet; professional installation is recommended if you are not comfortable with plumbing.
Only the dedicated faucet and its controls remain visible above the counter. The main ionizer body and filtration components stay inside the cabinet, making this the best fit for a clean, uncluttered countertop.
Choose 13 plates for the highest hydrogen performance in the range, or 9 plates for strong everyday performance in an integrated design. Compare H₂ output, plate count, live price, and available finishes before choosing.
Often, an unused soap-dispenser or accessory opening can accommodate the dedicated ionizer faucet if its diameter and location meet the faucet requirements. Measure the opening and surrounding clearance before installation; otherwise, a new sink or countertop opening may be needed.
The cabinet must accommodate the ionizer, filtration components, tubing, and service access without pinching hoses or blocking the drain plumbing. Check the selected model’s dimensions and reserve enough clearance to replace filters and perform maintenance.
Flow can vary with incoming water pressure, filter condition, tubing layout, and the selected ionization level. Correct sizing and installation help maintain normal operation; unusually low source pressure or clogged filters should be addressed before judging ionizer performance.
Filters and cleaning points must remain reachable inside the cabinet. Replace filters according to the model indicator and owner’s manual, and follow the recommended cleaning schedule—especially in hard-water areas—to manage scale and maintain consistent flow.
