Whole-Home Repipe + Tankless Conversion in Richmond, Texas

This home had already received a horizontal, attic-only PEX-b repipe after the 2021 freeze. When that system began failing across the house, Republic Plumbing rebuilt the entire water-distribution system and coordinated the repipe with a tankless conversion, filtration, fixture work, a new water service, and restoration.

Project overview

A second repipe—this time planned as a complete system.

This owner-occupied, slab-on-grade residence was approximately 2,184 square feet, with three full bathrooms and one half bathroom. A horizontal, attic-only PEX-b repipe had been installed shortly after the 2021 freeze. It did not replace every part of the water-distribution system.

Failures later developed in multiple areas and caused water damage across the home. After substantial damage occurred in a back bedroom, the homeowner chose to remove the prior repipe system and replace the remaining original piping rather than continue treating each failure as an isolated event.

Diagnosis first

The previous repipe had not solved the whole system.

On the first day of field work, Republic Plumbing found multiple out-of-code connections associated with the earlier installation. Several had already been sources of leaks, and additional connections were close to failing.

The issue was not simply that the house contained PEX-b. The decision was based on the documented failure pattern, connection methods, repeated water damage, remaining original piping, access conditions, and the homeowner’s decision to stop repeating partial repairs.

The leak history was the symptom. The condition and configuration of the larger system helped determine the scope.

One leak alone still does not establish that another home needs a repipe. This home’s accumulated evidence did.

Planning the water system

The work behind the finished walls

Republic Plumbing planned a complete Uponor® PEX-A water-distribution system from the whole-house shutoff to the fixture supply connections. Routing had to account for the slab foundation, attic and wall access, pipe support, insulation, existing fixtures, new valves, the tankless conversion, filtration, and the recirculation loop.

Because this was an occupied home, access and restoration were planned with the plumbing work. Openings were made where required to reach connections, while the work sequence and routing were organized to limit unnecessary reconstruction.

Open-wall routing, insulated water lines, fixture connections, valves, and pipe support during the Richmond whole-home repipe — Open-wall routing shows how water lines, fixture connections, valves, insulation, support, and existing building systems had to share the same wall.

Documented completed scope

More than replacing the water lines.

The repipe was the center of a broader plumbing-system rebuild. Each part had to connect to the same routing, access, shutoff, recirculation, and restoration plan.

Exterior supply workThe complete water service feeding the home was replaced, along with the broken irrigation-system PVB.

Before, during, and after

Rebuilding the mechanical wall as part of the whole system.

The original tank water heater used a separate recirculation pump, while the recirculation line emerged from the wall without proper support. With no filtration in place, the recirculation line had also become visibly discolored.

The finished arrangement combines whole-home filtration with a tankless heater that has an internal recirculation pump. Republic Plumbing incorporated the required return loop while repiping the house, then completed the wall around the new system. The completed work passed inspection without issues.

Restoration coordination

Plumbing access and finished-space planning belong in the same conversation

This project included documented restoration coordination associated with access openings and finish work. The exact restoration scope for another home is project-specific and should be defined in the proposal—not assumed from this example.

Republic Plumbing’s goal is to plan access and restoration clearly before work begins, while recognizing that conditions behind finished surfaces can change the final approach.

Field evidence

A project documented from failure pattern through finished work.

The case is supported by the prior system history, documented connections, open-wall routing, mechanical-wall progression, fixture work, restoration, water-service replacement, and a completed inspection.

What this project shows

Real experience, with clear limits.

This project demonstrates

Diagnosis of failures after a prior partial repipe
Complete Uponor PEX-A system planning
Tankless, recirculation, and filtration integration
Water-service, irrigation PVB, fixture, and valve coordination
Access, restoration, and inspection across a multi-step project

This project does not prove

That one leak means every home needs a repipe
That PEX-b alone determines replacement
That every repipe needs a new water heater or filtration
A universal price, duration, or access plan
That another home has the same conditions
