From the first shower we could tell the water was cleaner and softer. Dishes sparkle, skin feels better, and the OneSource team handled the install same-day. The copper work is spotless.

The crew rerouted and cleaned up our old exterior lines. The new copper work is tight, clean, and polished. They even pressure tested before leaving.

We finally ditched bottled water. The RO system fits neatly under the sink and runs quiet. Water tastes crisp and pure — best upgrade we've made this year.

They replaced our old water lines and filtration at the same time. Everything is solid and polished — feels like a high-end remodel upgrade.
