A leaking shower can be more than just an annoyance—it can lead to water damage, increased utility bills, and even structural issues if left unaddressed. From dripping showerheads to faulty valves and damaged seals, shower leaks come in many forms. This guide will help Exeter homeowners identify the source of shower leaks and provide practical solutions for common problems.
Common Causes of Shower Leaks
Before you can fix a leaking shower, you need to identify the source of the problem. Here are the most common causes of shower leaks we encounter in Exeter homes:
- Worn-out washers or O-rings - These small rubber components create watertight seals in your shower fittings and wear down over time.
- Damaged cartridge or valve - The internal mechanism that controls water flow and temperature can deteriorate.
- Cracked shower tray or base - Small cracks can develop in shower trays, allowing water to seep through.
- Deteriorated grout or sealant - The waterproof barrier between tiles can break down over time.
- Loose connections - Pipe connections behind the wall or under the shower can become loose.
- High water pressure - Excessive pressure can cause components to fail prematurely.
Diagnosing Your Shower Leak
The first step in fixing a leak is determining exactly where it's coming from. Here's how to diagnose different types of shower leaks:
1. Dripping Showerhead
If your shower continues to drip when turned off, the problem is likely with the valve cartridge or washers. To confirm this:
- Turn off the shower and observe where the dripping is occurring
- Check if the dripping stops when you adjust the handle slightly
- Note whether the leak happens with both hot and cold settings
2. Shower Mixer Valve Leaks
If water is leaking from around the shower control handle or escaping from behind the wall plate, you likely have a problem with the mixer valve:
- Look for water seeping from around the handle when the shower is running
- Check for damp patches on the wall surrounding the controls
- Listen for dripping sounds coming from inside the wall
3. Shower Tray or Enclosure Leaks
If water is escaping from the shower enclosure or tray:
- Inspect the silicone seal around the base of the shower for gaps or deterioration
- Check for cracked or damaged grout between tiles
- Look for water stains or dampness on ceilings below the shower
- Examine the shower tray for any visible cracks
DIY Shower Leak Repairs
Depending on the cause of your shower leak, here are some repairs you might be able to tackle yourself:
Replacing a Leaking Showerhead
If your showerhead is leaking where it connects to the arm, try these steps:
- Turn off the water supply to the shower
- Unscrew the showerhead from the arm (wrapping the arm with cloth to protect the finish)
- Clean any mineral deposits from the threads using vinegar
- Check the rubber washer inside the showerhead connector and replace if worn
- Apply plumber's tape to the threads of the shower arm
- Reattach the showerhead and hand tighten (avoid overtightening)
Resealing Shower Enclosure
To fix leaks around the shower tray or enclosure:
- Remove old, damaged silicone sealant using a silicone removal tool or blade
- Clean the area thoroughly with anti-fungal bathroom cleaner and allow to dry completely
- Apply new bathroom-grade silicone sealant in a continuous bead around the joint
- Smooth the sealant with a wet finger or specialized tool
- Allow to cure for at least 24 hours before using the shower
Repairing Grouting
Damaged grout between tiles can allow water to penetrate behind the tiles:
- Remove damaged grout using a grout removal tool or multi-tool with appropriate attachment
- Clean the gaps thoroughly and allow to dry
- Apply new waterproof grout, following the manufacturer's instructions
- Wipe away excess grout with a damp sponge before it sets
- Allow to cure for the recommended time before using the shower
- Apply grout sealer to protect from future moisture penetration
When to Call a Professional Plumber
While many shower leaks can be addressed with DIY repairs, some situations require professional expertise:
- Leaks inside walls - If water is coming from inside the wall, it could indicate damaged pipes that require professional access
- Shower valve replacement - Replacing a faulty shower mixer valve or thermostatic cartridge often requires specialized tools and knowledge
- Cracked shower tray - Repairing or replacing a cracked shower tray is a major job that usually requires professional installation
- Persistent leaks - If your DIY fixes aren't solving the problem, a professional can properly diagnose the underlying issue
