Frequently Asked Questions
What accessories are available for AMPAC USA residential RO systems?
This category covers the full range of add-ons and spare parts including replacement filter cartridges, dedicated RO faucets, pressurized storage tanks, tubing, fittings, pressure gauges, and post-treatment options such as alkaline and pH filters. Everything needed for installation, upgrade, or routine maintenance is available here.
Do I need a dedicated faucet for my RO system?
Yes. RO systems require a separate faucet mounted at the sink to deliver purified water independently from the main cold water tap. AMPAC USA offers standard single-handle RO faucets and air-gap models in chrome and brushed nickel finishes to match common kitchen hardware.
What size storage tank do I need for a residential RO system?
Standard under-sink RO systems pair with 3.2 to 4-gallon pressurized tanks, which hold about 2 to 2.5 gallons of usable water. Households with higher demand or low production rates may benefit from a larger 6-gallon tank. Tank pre-charge pressure should be set to 7 to 8 PSI.
What type of tubing is used in RO systems?
Most residential RO systems use polyethylene (PE) or John Guest push-fit tubing in 1/4-inch outer diameter. It is food-safe, easy to cut, and compatible with standard quick-connect fittings. AMPAC USA accessories include replacement tubing and fittings in common lengths for repairs or system extensions.
How do I know which accessories are compatible with my AMPAC USA system?
Most residential accessories use industry-standard sizing: 10-inch filter housings, 1/4-inch tubing, and standard tank valve threads. Check your system model number on the product label and match it to the replacement kit or part listing. Contact AMPAC USA support if you need help confirming compatibility.
