Professional Shower Valve Replacement in Oakville – Behind the Scenes with 17 Plumbing

Inside a Recent Shower Valve Upgrade Project in Oakville

At 17 Plumbing & Construction Design Ltd., we recently completed a full shower valve replacement in Oakville, and we're sharing the process to help homeowners understand when and why this service is necessary.


Problem Identified

The client reported inconsistent water temperature and poor water flow in their shower. Upon inspection, we discovered a corroded and outdated three-knob valve setup behind the wall, causing the issue. The system was no longer code-compliant and showed signs of internal failure.

Step-by-Step Replacement Process


1. Wall Access & Valve Exposure

To begin the replacement, we carefully cut the tiled wall to expose the existing plumbing behind it. Our team used precision tools to minimize tile damage while safely accessing the valve.

2. Old Valve Removal

The worn-out shower valve body was removed completely. We ensured the surrounding copper piping was intact and prepared for new fittings.

3. Installation of New Pressure-Balanced Valve

A modern pressure-balanced shower valve was installed using high-quality brass fittings. This new valve improves water flow control, ensures consistent temperature, and meets current plumbing code requirements.

4. Precision Soldering

Our technician used a torch to solder all copper connections securely. Every joint was pressure-tested for leaks and proper flow before reassembling.

5. Modern Chrome Trim & Spout Installed

Once the valve was securely in place, we installed a sleek chrome handle, trim plate, and matching tub spout — giving the shower a clean, updated look.



The system was tested thoroughly for leaks and temperature regulation. The client was thrilled with the improved pressure, updated look, and peace of mind from having a reliable, code-compliant shower system.
