Installation & Maintenance

No – Kelda showers are designed for straightforward installation by qualified installers. They use standard plumbing connections and are engineered to integrate easily into both new build and retrofit projects, without adding unnecessary complexity.

Yes – Kelda showers are designed to work with standard 150mm pipe centres, making them compatible with common UK plumbing layouts and ideal for retrofit installations.

Yes – Kelda systems are well-suited to retrofit applications. Their compatibility with standard plumbing layouts and focus on reducing hot water demand make them a strong addition to whole-house energy efficiency upgrades.

Kelda showers require both a water supply and an electrical connection, as the system uses air-powered technology to enhance performance while reducing water use.

No specialist certification is required. Any qualified plumber or installer can fit a Kelda shower, with guidance provided where needed to ensure a smooth installation process.

Kelda showers are designed to be low maintenance, with no complex servicing requirements under normal use. Their robust design supports long-term reliability in both residential and commercial settings.

Kelda systems perform reliably in hard water environments. Their design helps minimise the impact of limescale, reducing the likelihood of blockages and performance issues over time.

Kelda showers are built for durability and are already used in high-demand environments such as leisure facilities, where they are used over 100 times per day.

No – Kelda’s Air-Powered™ technology enhances the shower experience by combining water with air, delivering a powerful and immersive spray while using up to 55% less water.

Yes – Kelda showers are designed for consistent, everyday use in both residential and commercial settings, combining efficiency with long-term reliability.

Routine cleaning:

• – Wipe with a soft cloth and warm water
• – Use a glass cleaner to remove fingerprints (spot test first)

Important:

• – Avoid leaving chlorine, bleach, detergents, shampoos, or soaps on the surface
• – These can damage the finish and lead to rust spotting if not cleaned off

If deeper cleaning is needed:

• – Use a suitable stainless-steel cleaner to restore and protect the surface
• – If rust spotting occurs, thorough cleaning with a stainless-steel cleaner can help restore the finish

• – Isolate power supply to the Control Hub
• – Remove the air supply hose (loosen jubilee clip and ease off the air outlet adapter)
• – Remove the 90° elbow connector (unscrew ¾” air nut and loosen jubilee clip)
• – Remove the air return hose (loosen jubilee clips and remove from air inlet adapter and backplate vent)
• – Keep all jubilee clips and components safe
• – Submerge hoses fully in a disinfectant solution
• – Clean internally using a pipe cleaning brush, then flush through with disinfectant until clear
• – Rinse thoroughly with fresh water, shake out excess, and dry
• – Reassemble all components (air supply hose, 90° elbow connector, air return hose) and secure clips
• – Reinstate power to the Control Hub
• – Run the shower for 2–3 minutes to remove residual moisture

Important:

• – Do not direct water at the shower head while in use
• – Avoid abrasive or strong chemical cleaners, including bleach or chlorine

Kelda showers are designed for easy, low-maintenance cleaning.

Daily or weekly:

• – Wipe down the shower head and external surfaces with a soft cloth
• – Use a mild detergent or soap solution if needed
• – Rinse away any cleaning residue to prevent discolouration

For stainless steel panels:

• – Use a cleaner suitable for stainless steel only
• – Avoid bleach, chlorine, or harsh chemicals
• – If exposed to harsh cleaners, rinse and clean immediately with a stainless steel product

• – Dismantle the shower head
• – Clean, sanitise, and remove any light limescale from components
• – Reassemble following the provided instructions

Thanks to Kelda’s limescale-resistant technology, blockages are rare, so cleaning is driven by hygiene rather than performance issues.

Cleaning frequency can be adjusted based on site usage and maintenance schedules.

• – Inspect the shower head and air hoses for debris, wear, or damage
• – Clean or replace components if needed
• – Isolate the water supply and clean the strainer/filter

If a thermostatic mixer is fitted, follow the manufacturer’s maintenance guidance for that model.

• -Remove the fascia plate screw cap with a small flat head screwdriver (1)*.
• – Remove centre screw using a posi-drive PZ2, ensuring the fascia plate (2) and atomisation engine (3) are held until the screw is removed.
• – Slowly lower the fascia plate and atomisation engine.
• – Carefully detach the rubber hose from the water chamber (4), ensuring not to remove the hose from the other end.
• – Carry out clean, descale, and sanitisation of shower head components using industry-standard cleaning products.
• – To reassemble, follow the steps in reverse. Take care to correctly align nozzles (5).

After a period of non-use, the system should be disinfected and fully flushed in line with standard water hygiene procedures. All outlets should be flushed first, with Kelda showers left until last, ensuring water runs clear of any debris or discolouration. Filters and strainers should also be checked and cleaned.

Failure to properly flush the system may allow debris or limescale to block internal components such as solenoid valves, which can affect performance and may not be covered under warranty. Disinfection chemicals should remain in the system for 1–2 hours before flushing.
