Fixing a shower involves troubleshooting and potentially replacing various components to ensure proper functionality. Here’s an overview of the components commonly involved:

FIX-A-SHOWER Shower Hand Piece AYLA CP 3F CD1 Unpackaged 280213

Showerhead: The showerhead is the component that disperses water. If there’s poor water flow or irregular spray patterns, it may need cleaning or replacement. Mineral deposits can clog the spray nozzles, affecting water flow. You can try soaking the showerhead in a vinegar solution to dissolve deposits. Under our brand FIX-A-SHOWER, we sell an array of water efficient shower heads and more complete shower kits, with different designs and features to suit your tastes.

Shower Valve: The shower valve controls the flow and temperature of water. If there’s a leak, low water pressure, or inconsistent temperature, the valve may need repair or replacement. This involves shutting off the water supply, disassembling the valve, and replacing any worn-out seals or cartridges. What kind of repair part you need depends on what kind of tap you have. If you have a shower mixer, with one handle to control the hot and cold water flow, a mixer tap cartridge could help solve your problem. If you have separate 360 turn hot and cold taps, you may need a new tap valve or a new or refinished tap seat.

Shower Faucet Handles: Handles control the on/off function and temperature of the water. If they’re loose, difficult to turn, or leaking, they may need tightening or replacement. Depending on the type of faucet, this might involve simply tightening screws or replacing worn-out parts.

Cartridges: These are internal components of the shower valve that regulate water flow and temperature. Over time, they can wear out, causing leaks or temperature fluctuations. Replacing cartridges and seals can resolve these issues. It’s important to ensure your replacement part matches your shower valve. Common sizes of mixer tap cartridges are 25mm, 35mm and 40mm.

FIX-A-SHOWER Handshower Washer Flexi Fibre BP20 Unpackaged 233233
Seals and washers: If your shower is leaking between joins, a new washer may be all you need. FIX-A-SHOWER sell an array of shower washers to fix these types of leaks.

FIX-A-SHOWER Shower Wall Elbow CP DZR Brass CD1 Unpackaged 280404

Shower Elbows: This is the join between your shower hose and the pipe threads on the wall. It can be easily replaced by installing a new wall elbow.

FIX-A-SHOWER Shower Hose Flexible 1.5m S/S Chrome CD1 Unpackaged 280336
Shower Hoses: If you have a hand shower where water flow is not sufficient, it could be a blockage within your shower hose. Poorly maintained shower hoses can also lead to leaks and can look unsightly. Fortunately these are easy to replace. FIX-A-SHOWER has a range of shower hoses which can easily be screwed in for a fast fix.

For many of the above issues, it may simply be easier to purchase a new shower kit. These products conveniently contain all parts for replacing a shower, with many being easy to install! For simple shower kits, simply screw the new kit onto the wall pipe and the job is done. For rail kits, the job can be a bit more difficult if there was no rail previously installed, however if there was, our FIX-A-SHOWER rail kits all feature adjustable fixings, so that they can be adjusted to fit to your old tile holes.

Piping and Plumbing Connections: Leaks in the piping or connections behind the shower wall can cause water damage. Identifying and fixing leaks may involve tightening fittings, replacing damaged pipes, or applying sealant to connections. For major plumbing issues, it’s advisable to seek professional help.

Grout and Caulk: The grout and caulk around the shower enclosure can deteriorate over time, leading to leaks and water damage. Repairing or replacing grout and caulk can prevent water from seeping into the walls or floor. This typically involves removing the old material and applying new grout or caulk.

Drain Assembly: If water isn’t draining properly from the shower, there may be a clog in the drain or the assembly may need adjustment. Removing hair and debris from the drain or adjusting the drain stopper can improve drainage.

Water Pressure Regulator: In some cases, low water pressure in the shower may be due to a malfunctioning water pressure regulator. This component regulates the water pressure entering your home. If it’s faulty, it may need adjustment or replacement.

Shower Enclosure: If the shower enclosure itself is damaged or leaking, repairs may involve resealing seams, fixing cracks, or replacing damaged panels.

Water Heater: Issues with water temperature in the shower could be related to the water heater. If the water isn’t heating properly or fluctuates in temperature, the water heater may need repair or maintenance.

When fixing a shower, it’s essential to prioritize safety and follow proper procedures. If you’re unsure about how to proceed or if the issue seems complex, it’s best to consult a professional plumber. They can accurately diagnose the problem and recommend the most appropriate solution.
