Your unit. A clear installation plan.

Under-sink RO installation
with the details checked first.

This service is for a customer-supplied drinking-water system at the kitchen sink. The model, cabinet space and existing plumbing determine the installation scope.

01 / Systems with a tank

Room for the unit and storage tank

Dustin reviews the available cabinet space, mounting locations and route to the drinking-water faucet before confirming the work.

02 / Tankless systems

Check the model’s power requirements

A powered system needs suitable existing electrical power. Adding an outlet, circuit or wiring is not included in this installation.

03 / Dishwasher connections

A dual air gap when the setup calls for it

A compatible dual air-gap assembly can accommodate the dishwasher and RO wastewater lines in an existing opening. The assembly and connections are reviewed as part of the quote.

What the installation covers

Mount. Connect.
Flush and check.

The agreed work includes mounting the system, connecting it to suitable existing water and drain connections, and installing its drinking-water faucet in an existing compatible opening.

Startup flushing and leak testing follow the system’s installation instructions. Send the complete model information so the required parts and setup can be reviewed.

A working, accessible shutoff and compatible connections matter. Corroded fittings, unsuitable drain arrangements or missing parts can change the work needed.

A useful first conversation

Show the whole cabinet,
not just the box.

Text the product link or model number, a wide photo inside the sink cabinet, and a close view of the water and drain connections. Include the sink’s available faucet opening and your Irvine ZIP code.

If you already have a system installed, include a photo of it and say what you want changed. Dustin can review the proposed installation before you commit to equipment.

What affects the estimate?

  • The tank or tankless model and included fittings
  • Mounting space and access around the sink
  • Condition and compatibility of existing shutoffs and drain connections
  • The drinking-water faucet opening and any dual air-gap assembly needed
  • Suitable existing power for a model that requires it

You receive a project-specific installation quote. The customer supplies the RO system.

Common questions

Before your RO installation

Do I supply the reverse osmosis system?

Yes. This service is for a customer-supplied unit. Send the model or product link before ordering so Dustin can review the installation requirements and visible connections.

Can you install a tankless RO system?

Compatible tankless under-sink systems can be assessed for installation. The cabinet, connections and any required existing power must suit the model. Electrical work is not included.

Does installation include a new hole in the countertop?

This scope uses an existing compatible opening for the drinking-water faucet. If you do not have one, mention that before buying the system or scheduling installation.

What if the dishwasher uses the existing air-gap opening?

Send a photo of the sink deck and under-sink drain arrangement. A suitable dual air-gap assembly may be part of the agreed work, depending on the RO model and existing connections.

How much does RO installation cost in Irvine?

Dustin quotes the installation after reviewing the unit, cabinet space, faucet opening and connections. Send the model and photos for a scope-specific estimate; no equipment package price is included here.

Dustin from Ultra Home Repair did an excellent job professionally descaling my tankless water heater and optimizing its settings\. Before his visit, the hot water wouldn’t turn on unless I opened two faucets, and even then, it took a long time to arrive\. Since Dustin serviced the unit and switched it to Comfort Mode, the hot water has been working beautifully\. The improvement has been life\-changing\! The service cost was also very reasonable\. Ultra Home Repair is honest and upfront, and they won’t gouge you like others\. Professional, knowledgeable, and highly recommended\. Thank you, Dustin\!
