Three-Way Valve Replacement for Toronto Condos
Valve stuck, leaking, or can't modulate? Temperature swinging wildly? Your fan coil's 3-way valve may need replacement—a repair we handle routinely.
Three-way valves control water flow in your fan coil by mixing or diverting supply and return water. When they fail, you lose temperature control—stuck at one extreme, fluctuating constantly, or leaking water. Hudson HVAC diagnoses and replaces failed 3-way mixing and diverting valves from Belimo, Honeywell, and all manufacturers found in Toronto condos.
Corroded or stuck 3-way valves are common in older condos. We diagnose whether you need a valve body or actuator replacement.
Expert Valve Service
Three-way valve replacement is more involved than actuator-only repairs but is a routine job for our technicians. We carry common valve sizes and can complete most replacements in a single visit. Restore proper temperature control to your suite.
Signs your three-way valve needs replacement
These symptoms indicate a failing or failed 3-way valve. A professional diagnostic determines if you need a valve body replacement or just an actuator.
Valve Leaking
Water dripping from valve body or stem. Seals have failed or body is corroded. Requires valve replacement.
Temp Fluctuating
Temperature swings wildly, won't hold steady. Valve can't modulate properly due to corrosion or mechanical wear.
Stuck at Extreme
Unit stuck full hot or full cold. Valve ball/plug seized in one position and won't move.
Grinding Noise
Grinding or straining sounds from valve area. Actuator fighting against corroded/stuck valve internals.
No Flow
Actuator moves but no temperature change. Valve stuck closed internally, blocking water flow.
Visible Corrosion
Green/white buildup on valve body, pitting, or obvious deterioration. Valve nearing or past end of life.
What causes 3-way valve failure in Toronto condos?
Three-way valves are mechanical components exposed to building water 24/7. Water quality, age, and usage patterns all affect their lifespan.
Age & Wear
Valve seals, seats, and internal components degrade over time. Most 3-way valves last 15-25 years, but constant cycling and water exposure eventually cause mechanical wear.
Scale & Corrosion
Minerals in building water deposit on valve internals, restricting movement. Corrosion from dissolved oxygen or improper water treatment pits metal surfaces and causes seizing.
Debris Accumulation
Particles from old pipes, rust flakes, and sediment can accumulate in the valve, preventing proper seating and causing leaks or stuck conditions.
Actuator Stress
A failing actuator can damage the valve by applying excessive force. Conversely, a stuck valve can burn out actuators. Both should be checked together.
Poor Water Treatment
Buildings with inadequate water treatment programs see accelerated valve corrosion. Aggressive water chemistry attacks metal components, especially in older buildings.
Our three-way valve replacement process
A methodical process to replace your failed valve and restore proper temperature control. Here's what to expect.
Diagnostic Assessment
We determine if the valve body, actuator, or both need replacement. We check for leaks, test actuator operation, and inspect valve condition to recommend the right solution.
Part Identification
We identify the correct valve size, type (mixing or diverting), and connection style. We stock common sizes and can source specialty valves within 1-2 days.
Water Isolation
We isolate water supply using in-suite valves or coordinate with the building for a riser shutdown if needed. Water is drained from the work area.
Valve Replacement
We remove the old valve, install the new one with proper connections, and mount the actuator. All connections are sealed and secured for leak-free operation.
Leak & Function Testing
We restore water flow, check all connections for leaks, test actuator operation, and verify temperature modulation from the thermostat.
Documentation
You receive a detailed service report with photos, old/new part info, and warranty details. We note any additional recommendations.
