Variables

What changes the number

These are the specific factors that determine your quote — knowing them lets you compare quotes apples-to-apples instead of guessing. For your real installed price, use the get an instant plumbing quote link below — it accounts for all of these automatically.

Under-sink vs. whole-home

Under-sink RO covers drinking + cooking water at one tap. Whole-home RO treats every fixture in the house — much higher capacity, requires storage tank + repressurization pump.

Number of stages

3-stage: minimum (pre-filter, RO, post). 4-stage: adds carbon. 5-stage: adds remineralization (better taste). 6+ stages add UV or alkaline (mostly marketing for Utah water).

Membrane GPD rating

50 GPD: standard. 75 GPD: faster recovery for high-use families. 100 GPD: light commercial use.

Tankless RO

Newer tankless RO units skip the storage tank for a more compact install. Slightly higher cost, takes 5–10 seconds to dispense.

Scope

What's included vs. extra

Compare this list against any other Utah quote you receive — line items hidden in one quote and itemized in another are how the same job ends up “cheaper” on paper but more expensive after add-ons.

FAQ

Frequently asked questions

Is reverse osmosis worth it on Utah municipal water?

Yes for drinking + cooking + ice. Utah TDS levels (300–500 ppm typical) are within EPA limits but on the high end of palatability. RO drops TDS to 10–30 ppm, eliminates chlorine taste, and removes any contaminant traces. We don't recommend whole-home RO for Utah municipal — overkill — but under-sink RO is a quality-of-life upgrade most families notice immediately.

Why do RO systems waste water?

Standard RO produces 1 gallon of clean water per 3–4 gallons of input — the rest goes down the drain as concentrate. Tankless RO units have improved this to 1:1 efficiency. Worth knowing for high-water-bill homes; not a meaningful cost for typical Utah usage.
