Common questions

Do you charge for service calls or site visits in the Phoenix area?

No. Site visits, consults, and service calls are always free across the Phoenix Metro — you only pay for the work you approve.

How often should RO filters be replaced in Arizona?

With Phoenix-area water hardness, prefilters and DI resin need changing every 3–6 months, and membranes every 1–2 years. We test your water and set the right schedule — or put you on a maintenance plan so it's handled automatically.

Do you service RO/DI systems for reef tanks and aquariums?

Yes — aquarium and reef RO/DI is a specialty. We install and service RO/DI units, replace DI resin, and set up TDS monitoring for stable, pure top-off water.

Which brands do you service?

We're a SpectraPure® authorized dealer and repair center, and we service every major RO and RO/DI brand.
