Shower Valve Repair in Ajax

Telltales that call for shower valve repair

Shower valves wear slowly. The handle gets stiff, the temperature drifts, or the shower takes a long time to stop dripping after you turn it off. Sudden scalding or icy bursts when someone flushes a toilet point to a pressure-balancing part that has failed or a valve that never had one.

• A steady drip from the showerhead or tub spout
• Hot water that fades early, though the heater is fine
• A stiff or loose handle
• Water temperature that jumps when another tap is used

How we do the work

We shut off the water, take off the trim and look at the brand and model of the valve. Most single-handle valves use a replaceable cartridge, and a new one usually brings back smooth control. Older two- and three-handle valves have stems and seats we can rebuild. If the hot water is short, we check whether the cartridge's temperature limit stop needs resetting before blaming the water heater.

When parts are no longer made or the valve body is corroded, a replacement is the honest answer. From the front that usually means opening the tile around the valve; from behind, through an access panel or the closet wall.

On Ajax streets

Many Ajax homes from the 1970s and 1980s have original valves from brands that changed their parts lines years ago. In those houses we often bring a selection of cartridges and seats, and sometimes order parts after the first visit. Hard water also wears seals faster, which is one reason a softener helps showers last.

Price swings on

A cartridge swap on a common valve is a short visit. Older or uncommon valves take more time to find parts, and a full replacement depends on how the wall can be opened.

Worth asking the plumber

• Is my valve pressure-balancing or thermostatic?
• Can it be repaired from an access panel?
• Should the valve be upgraded during a renovation?

Signs of a hidden leak

A worn valve can leak inside the wall rather than out of the spout. Watch for loose tiles near the handle, peeling paint on the ceiling below, or a musty smell from the closet next door. If you notice any of these, shut off the shower supply if you have one and call before the damage spreads. Our leak detection work can confirm where the water is going.

Shower valves also need the trim sealed properly against the tile; a failed seal lets water behind the wall every time you shower.

Keep any spare cartridge we leave in a labelled bag near the water heater.
