This Bristan Sirrus Gummers Shower Valve features adjustable pipe centres and elbows, allowing it to replace showers with various pipe centre configurations, including 110mm, 130mm, 138mm, and the industry standard 150mm, as well as anything in between. It offers automatic thermostatic shut-off in case of hot or cold water failure, check valves, and serviceable filters as standard. The shower is chrome plated to BS EN 248 and comes with a 1-year guarantee covering manufacturing faults. Please note, this is the valve only and does not include a riser kit. The included elbows can be adjusted for exposed pipework running vertically on the wall with a wide range of centre configurations. Each Bristan Mini Valve is supplied with two sets of elbows, enabling replacement of almost any shower mixer valve with inlet centres ranging from 110mm to 155mm. Choose the correct elbow configuration based on your inlet centres: 2 x small elbows for 110-130mm centres, 2 x large elbows for 136-155mm centres, or 1 small and 1 large elbow for 125-145mm centres. It provides single sequential control for both temperature and flow, offers high performance even at 0.5 bar inlet pressure, and includes automatic shutoff in the event of hot or cold water supply failure.
