A leaking shower in Kingston rarely starts with a flood. It starts with a drip from the showerhead after the water is off. It starts with water pressure that fades a little each month. It starts with a handle that turns stiff or a temperature that swings hot and cold without warning. The cause often sits behind the wall. The shower valve controls the flow and the mix of hot and cold water. Inside the valve, a cartridge does the work. When the cartridge wears out, the valve cannot shut off cleanly or mix water properly. The shower drips, loses pressure, or runs at the wrong temperature. Leak Free Plumbing repairs showers for homes and businesses in Kingston, Odessa, Bath, Inverary, and Amherstview. Call (613) 876-6688 if your shower drips, loses pressure, or will not hold a steady temperature.
What a shower valve and cartridge do
The shower valve sits behind the wall, behind the handle and the trim plate. It connects to the hot and cold water lines. The cartridge inside the valve controls how much water flows and how the hot and cold mix. Turn the handle and the cartridge opens the flow. Shut the handle off and the cartridge should seal the flow completely. The cartridge has seals and moving parts that wear with use and with mineral buildup in the water. A worn cartridge cannot seal fully. Water keeps passing through after the handle is off. That water shows up as a drip from the showerhead or the tub spout. A worn cartridge can also stick, which is why a handle turns stiff or the temperature jumps.
Signs the valve is the problem
Watch for a showerhead that drips for minutes after you turn the water off. Watch for a slow drip that never stops, even with the handle fully closed. Watch for water pressure that drops in the shower while other taps in the house run fine. Watch for a handle that feels stiff, loose, or gritty when you turn it. Watch for temperature that swings hot and cold during a shower without anyone touching another tap. Watch for water staining or dampness on the wall behind the shower or on the ceiling below it. A drip that never stops plus a stiff handle points to the cartridge. A pressure drop in the shower only, with good pressure elsewhere, also points to the shower valve or the showerhead, not the main water supply.
Why shower valves fail
Shower valves fail for ordinary reasons. The cartridge wears out with years of daily use. Mineral buildup from hard water coats the cartridge and the valve parts, which makes them stick and wear faster. Rubber seals inside the cartridge harden and crack with age. A valve installed years ago may use parts that are no longer made, which limits repair options. In many cases the tile, the showerhead, and the pipes are fine. The repair focuses on the valve and the cartridge behind the wall.
What a shower valve repair involves
A shower valve repair starts with shutting off the water to the shower. The plumber removes the handle and the trim plate to reach the valve. The old cartridge comes out and gets checked for wear, corrosion, and mineral buildup. A matching replacement cartridge goes in, with new seals. The plumber then turns the water back on and checks the flow, the temperature mix, and the shut-off. If the valve body itself is corroded or damaged, the plumber replaces the valve. That is a bigger job, since the valve sits behind the wall, and it may need a small access opening. The job also includes a check for water damage. A leak behind the wall can soak drywall and framing, and dampness there needs attention before it spreads.
What not to do with a leaking shower
Do not keep using a shower that drips all day. A slow drip wastes water every hour, and a leak behind the wall damages the structure a little more each day. Do not force a stiff handle. Forcing it can break the cartridge or crack the valve body, which turns a cartridge swap into a valve replacement. Do not ignore a temperature swing. A cartridge that cannot hold a steady mix can send scalding water without warning. Do not seal over a leak with caulk around the trim plate. Caulk hides the water without fixing the valve, and the leak keeps soaking the wall behind it.
When to call a plumber
Call a plumber when the showerhead drips after the water is off. Call when the shower loses pressure while other taps run fine. Call when the handle turns stiff or the temperature swings on its own. Call when you see dampness on the wall behind the shower or on the ceiling below it. These are valve problems, not cleaning problems. A prompt repair protects the wall and keeps the shower safe to use. Leak Free Plumbing provides 24/7 emergency service and repairs for homes and businesses. Every job is priced individually for its own situation, with flat-fee pricing quoted per job and approved before work begins.
FAQ
Why does my showerhead drip after I turn the water off?
A worn cartridge inside the shower valve cannot seal the flow completely. Water keeps passing through after the handle is off and drips from the showerhead. A new cartridge usually fixes it.
Can a leaking shower damage my house?
Yes. A drip from the showerhead wastes water. A leak behind the wall is worse. It soaks drywall and framing, which can lead to mould and structural damage over time. A damp wall near a shower or a stain on the ceiling below it needs a plumber soon.
Is low shower pressure always a valve problem?
No. Low pressure in the shower only, with good pressure at other taps, often points to the shower valve, the cartridge, or a clogged showerhead. Low pressure at every tap points to the main supply or the main valve instead.
How do I know if I need a new cartridge or a new valve?
You usually cannot tell without opening the valve. A plumber removes the trim and the cartridge, checks the cartridge for wear, and checks the valve body for corrosion. A worn cartridge gets replaced. A corroded or cracked valve body needs a new valve.
