Scope
What we handle
Supply pipe repair & repiping
Copper, PEX, and full polybutylene replacement, section by section or whole-house.
Water heaters
Tank and tankless: replacement, expansion tanks, T&P valves, and recirculation.
Fixtures
Toilets, sinks, tubs, showers, laundry boxes, hose bibs, and utility sinks.
Valves & controls
Main shut-offs, angle stops, pressure-reducing valves, and backwater valves.
Pressure problems
Diagnosing whether low pressure is the city supply, the PRV, or scaled pipe.
The short answer
Depex repairs and installs the full potable-water side of your home or building — supply lines, shut-off valves, water heaters, toilets, sinks, showers, and outdoor bibs. We work on copper, PEX, poly-B replacement, and galvanized retrofits across the Tri-Cities, Burnaby and Pitt Meadows, and we quote a flat price before any work starts.
Signs it's time to call
- Water pressure has dropped across the whole house, not just one tap
- Grey polybutylene supply pipe visible at the water heater or under sinks
- Rusty or discoloured water first thing in the morning
- A water heater older than about twelve years, or one that rumbles
- Shut-off valves that seize or weep when you try to turn them
Live answer 24/7 — no overtime charges.
Local detail
What's different about this job in the Tri-Cities
Polybutylene is the one to know about in this region. If your Tri-Cities home went up between roughly 1978 and 1995, there is a fair chance the supply lines are grey poly-B with acetal fittings — a system with a well-documented tendency to fail at the fitting, without warning, behind a wall. Replacing it on a planned schedule costs a fraction of replacing it plus the drywall, flooring, and insurance deductible afterwards.
Answers
Plumbing Repair & Installation: common questions
The questions we get asked on almost every one of these calls.
How long does a water heater replacement take?
A straightforward like-for-like tank swap is usually three to four hours including draining the old unit, hauling it away, and testing. Converting to tankless is a bigger job — gas line sizing, venting, and often an electrical circuit — and typically takes a day.
Should I repipe the whole house or just fix the leak?
It depends on what the pipe is. A single pinhole in otherwise sound copper is a spot repair. A poly-B fitting failure is a warning — the rest of the system is the same age and the same material. We'll show you what we found and let you decide, with a price for each option.
Do I need a permit?
For a like-for-like fixture swap, generally no. For altering or extending pipe, moving a fixture, or replacing a water heater in most cases, yes — and we pull it. Permitted work gets inspected, which is protection for you when you sell.
