We need to save water, it’s our shared responsibility. With summer now here, there are some simple but effective solutions that plumbers can implement in new systems, as well as retrofits, which can really help to ensure that water is used most efficiently. 

Here are our four key tips to help end-users save water through optimised plumbing systems.

Conduct a survey

Conducting a survey on all fixtures and appliances will allow you to calculate their precise flow rate. 

First, establish exactly how much water is being used and where. Toilets often have built-in devices that limit the water supply to the cistern to a 6 or 9l flush, so are easy to calculate, however taps, baths, and showers often don’t have these, and therefore need to be measured to establish the exact flow demand. 

Second, look to benchmark these calculations against water saving standards to ensure they only draw the amount of water that’s recommended.

Check for leaks 

One of the most effective ways to ensure water is being used efficiently is to look for leaks in the system and address them. 

Whether it’s a dripping tap or water leaking into a WC pan, over time the water wasted soon adds up. Installing a leak detection system, like the Reliance Valve Multisafe, to monitor for leaks can really aid in prevention, and ensure that no matter how small the leak, it can be located and rectified easily.

Install flow regulating valves

Flow regulating valves, like the Reliance Valves Floreg Isolating Valve, are fitted to a fixture or appliance to ensure a stable flow rate is achieved. But they also guarantee a set flow rate by ensuring that excessive amounts of water cannot be pulled through. 

On applications that require a high flow rate, for example baths, taps, or showers, we would still advise to control the flow so it isn’t too excessive – and doing this can really aid in calculating the pipe sizing required to serve these outlets. Oversized pipework can add to unnecessary water waste, therefore correct sizing and regulation ensures an accurate and reliably measured flow rate.

Reduce the pressure

You can limit excessive flow by reducing pressure in the system. The higher the pressure, the higher the flow rate, so by installing a PRV, like the 315i Pressure Reducing Valve, you can stabilise water consumption in an application.
