What matters

Shutoffs, slope, future access and leak testing.

Costly mistake

Concealing an unverified connection.

When to delegate

Permit or authorized contractor depending on the change.

Respiratory protection

Select for the hazard, never by appearance

Full mask guide

Possible hazards

  • task-specific dust or products to confirm
hazard assessment first

Priority controls

  • Eliminate or reduce dust/vapour at the source before relying on a respirator.
  • Use appropriate wet methods, HEPA capture, local exhaust and isolation.
  • Read the SDS and exact product instructions.

What is not sufficient

  • Choosing a respirator by appearance or colour is not a selection method.

Stop if

  • Stop if the contaminant is unknown, air is inadequate, a seal is impossible or symptoms occur.

Final selection depends on contaminant, concentration, SDS, fit and the applicable program. An air-purifying respirator does not supply oxygen.

Red phase — professional oversight

Plumbing, drainage and water management

A red page does not authorize a homeowner to perform regulated or high-consequence work. It is for preparation, oversight, documentation and acceptance. Permits, sealed drawings, provincial/municipal rules, manufacturer instructions, inspections and required trades prevail.

Absolute limit

This page explains expected professional work and homeowner oversight; it does not provide a procedure for personally performing regulated or hazardous operations.

Complete system to oversee

  1. 1

    source, pressure and shutoff

  2. 2

    distribution and contamination protection

  3. 3

    fixtures and connections

  4. 4

    drainage, slope, venting and cleanouts

  5. 5

    leak tightness, supports and freeze protection

  6. 6

    testing, flushing and commissioning

Homeowner can do

  • Define the need, expected result, constraints and maximum budget.
  • Photograph, measure without dismantling and gather available drawings, invoices and history.
  • Verify the authority having jurisdiction, permits, licences, insurance and references.
  • Compare quotes using identical scope, products and quantities.
  • Prepare access, protect belongings, keep a log and retain photos.
  • Observe inspections without touching open, energized or pressurized systems.
  • Refuse concealment of work that has not been inspected, tested and photographed.
  • Complete written acceptance and retain final payment until corrections and documents are delivered.

Sometimes possible if allowed and competent

  • Move furniture and protect unaffected areas if this can be done without exposure.
  • Paint or complete cosmetic finishes only after concealed work is accepted, if permitted and within skill.
  • Purchase products approved in the quote without substituting system components.
  • Perform user maintenance listed in the manual after training and commissioning.

Must be done/verified professionally

  • diagnose pressure, flow, drainage and pipe condition
  • confirm required materials, sizes, slope, venting and safeguards
  • isolate, drain and protect the area before opening
  • install and support piping, devices and fixtures to the plan
  • perform pressure or leak tests before concealment
  • flush, disinfect where required, adjust and deliver valve map

Never improvise

  • Never open an electrical panel, alter gas/refrigerant connections, defeat a safeguard or work energized.
  • Never remove a load-bearing element or start excavation without design, stability controls and utility locates.
  • Never disturb suspected asbestos/lead material or significant contamination without qualified assessment.
  • Never enter an unknown, confined or oxygen-deficient atmosphere with an air-purifying respirator.
  • Never backfeed a home through a receptacle or improvise transfer equipment.
