PEX Manifold, Backflow & Water Heater Rough-In

Project Overview

During a whole-house renovation in Larchmont, the contractor asked us to replace all of the original supply piping and set up a new mechanical area in the garage.

We installed a PEX home-run manifold with individual fixture valves, a pressure tank and filtration loop, an exterior backflow preventer for the irrigation system, and a new water heater with sump and condensate routing.

What We Did

Scope of work for this repiping & leak detection project in Larchmont, Norfolk:

  • System design & layout
  • Copper / PEX supply piping
  • Isolation & zone valves
  • Pressure test & inspection
  • Labeled, serviceable install
PEX Manifold, Backflow & Water Heater Rough-In in Larchmont, Norfolk

The Challenge

The walls were open for only a short window before insulation, so every line, stub-out and valve had to be placed and pressure tested on a tight schedule.

  • Short open-wall window
  • Irrigation cross-connection
  • Low incoming pressure
  • New mechanical area layout
  • Multiple trades on site
  • Inspection timing

The Outcome

Rough-in passed inspection on the first visit and the homeowners now have a manifold that lets them shut off any single fixture from one place.
