What this job involves
The incoming valve outranks every other valve in the house, and in many older Oakville homes it is the one nobody trusts. Old wheel-handled gate valves seize, weep around the stem, or close only part way. A full-port ball valve with a lever takes its place, closing completely with one ninety-degree swing, so in a crisis even a teenager home alone can stop the water.
How the job goes
- Arrange for the curb stop to be closed if the house valve will not hold.
- Drain the house lines to the lowest tap.
- Cut out the old valve and dress the pipe ends.
- Install a full-port ball valve with sound joints.
- Restore water and show everyone home where the lever is.
Warning signs on your pipes
- The wheel will not budge.
- Water beads around the valve stem.
- The wheel turns but water keeps flowing.
- Shelving or drywall hides the valve.
- Nobody in the house knows where it is.
From the job notes
In older Oakville homes the incoming valve often hides in a front basement corner, behind a furnace-room partition or tucked under the stairs.
In older Oakville homes the incoming valve often hides in a front basement corner, behind a furnace-room partition or tucked under the stairs. If a finished basement has swallowed it, we can fit an access hatch.
Swapping it may require the curb stop to be closed. Halton Region manages curb stops, and we follow their process when that step is needed.
