One faucet, one cabinet, one filter change a year. That’s the whole footprint of an under-sink reverse osmosis system in a Sun City kitchen. It removes most dissolved minerals, metals, and off tastes from drinking and cooking water, and it can feed the refrigerator’s ice maker as well. We size it to your water and leave the service dates written on the housings.
Water in Sun City arrives carrying roughly 15 to 20 grains of dissolved mineral per gallon. That is chemistry, not gossip, and it settles in the bottom of every tank and the throat of every valve in town. Run the numbers for your own house and most questions about this kind of work start answering themselves.
“It tastes like the pool.” That is how a lot of people describe Phoenix tap water, and they aren’t entirely wrong. Utilities add disinfectant so the water stays safe across a very long network of pipe, and in summer the rivers and canals that feed the Valley can bring an earthy, musty note along with it. Add the minerals that make the water hard, and a glass from the tap has a lot going on. Little of it is harmful. Plenty of it is unpleasant.
Signs the system needs service
The RO faucet trickles
Slow flow usually means clogged prefilters, a fouled membrane, or a tank that has lost its air charge. All three are fixable, typically in one visit.
That taste is back
Chlorine or a musty note in RO water means the carbon stages are spent. Change them before the chlorine reaches the membrane.
A TDS reading close to the tap’s
The membrane has stopped rejecting much of anything. Membranes wear faster on hard water, and a spent one looks perfectly normal from the outside.
Water running to the drain all night
A steady trickle under the sink long after the tank should be full points to a failed shutoff or check valve. The system keeps producing, and wasting, around the clock.
Drips inside the cabinet
Filter housings, tubing connections, and the drain saddle are the usual sources. Particleboard cabinet floors swell fast, so it’s worth a look whenever the trash goes out.
When were the filters last changed?
If nobody in the house knows, it has been too long. Prefilters generally want changing about once a year, more often on hard or well water.
