As long as your current mixing valve meets the minimum operating pressure requirements, then there is no needs to replace your mixing valve. Minimum operating pressure is 1 bar/100 KPA/14.5 PSI. The handset needs a ½ inch BSP hose. This will be compatible with most existing fittings.
The handset is made of quality crafted materials. Rua is made entirely of high-performance polymers. The handle and faceplate cover are made of ABS as it allows a hard wearing chrome plated surface to be applied. All internal engine components are made from PPO as it is highly durable, has exceptional dimensional accuracy and very good chemical resistance. The impinging surface is made from PP, chosen specifically for its low surface energy, meaning it resists build-up and preserves spray quality. Everything that comes into contact with water complies with global standards.
Rua feels like no other shower. It offers an enveloping warmth that gently invigorates. This delivers an amazing shower experience like no other that puts you in a good space every time. Rua generates big droplets in an evenly distributed pattern, which delivers up to a lot of total spray force, to stimulate nerve endings. Conventional showers simply drop water, in an uneven, narrow pattern. But why settle for that, when water is capable of so much more. Rua great water contact with the skin at any given time, delivering an amazing and invigorating shower.
Rua's the impinging surface is made of a hydrophobic material which helps to repel water and avoid build-up of limescale. Build up of minerals is still possible within the spray nozzles themselves like most conventional showers. Limescale can be cleaned by soaking the shower head in a mild acid such as warm vinegar so regular attention to this would be good for areas with particularly hard water.
