The service covers new connections, upgrades and repairs, with a tidy approach that helps keep your site running with minimal downtime. ## What commercial appliance water connections cover A correctly installed connection protects your appliance, your water supply, and your premises. Typical work includes: - New hot or cold water supplies to commercial appliances - Alterations to existing pipework to suit new layouts or equipment - Isolation valves for safe shut-off during maintenance - Backflow protection (for example, check valves or air gaps where required) - Pressure and flow checks to support correct appliance performance - Leak finding and repairs on feeds, fittings and supply pipework - Replacement of worn, non-compliant, or poorly installed components - Commissioning checks and basic user handover on shut-off points ### Who this service is for This service is well suited to offices, retail units, cafés, small hospitality sites, and light industrial premises that need dependable appliance feeds. It is often booked when you are fitting new equipment, refurbishing a kitchen or staff area, or dealing with repeated leaks and low pressure. Landlords and facilities contacts also use it to keep sites compliant and reduce call-outs. ### How the work is delivered Work usually starts with a quick review of the appliance requirements and the existing supply route, then agreeing the most practical isolation points and protection measures. The connection is installed or repaired, then tested for leaks and correct operation before the area is left safe and tidy. Where access needs to be managed around trading hours, the aim is to sequence shut-offs and testing to limit disruption. ### After the connection is completed You will be shown where the isolation valve is and what to do if you ever need to shut the appliance supply off quickly. If issues like scale, debris, or pressure instability are likely to affect performance, you can be advised on options such as filtration, pressure reduction, or a small rework of the feed to improve reliability.

Most plumbed-in commercial appliances can be connected, including coffee machines, dishwashers, glasswashers, ice makers and water boilers. The connection method depends on the appliance spec and the required backflow protection. Do you make sure the connection meets water regulations? Yes, the connection is set up with compliance in mind, including suitable fittings and backflow prevention where needed. If existing pipework is not compliant or is unsafe, you will be told what needs changing before work proceeds. Can you work outside of opening hours to reduce disruption? Where practical, shut-offs and noisy work can be planned around your quieter periods. You will be advised in advance if a water isolation is required and roughly how long it is likely to affect the area. What if the water pressure is too low for the appliance? Pressure and flow can be checked as part of diagnosing poor performance. If improvements are needed, options may include adjusting the feed route, replacing restricted valves, or fitting a pressure booster or reducer where appropriate. Do you repair leaks on existing appliance feeds? Yes, leaking valves, hoses, fittings and supply pipework can be repaired or replaced. The connection is then tested to confirm it is watertight and safe to leave in service.
