The customer has a bearded collie that loves muck and is always needing a shower off. Inside is a TMV3 valve with a lever valve after it to isolate in the winter. The TMV has single check valves on the inlet and this is the lowest point on the hot water system so this is sufficient to prevent backflow. The cold is mains fed through a pressure reducing valve so I've fitted another single check before the PRV to provide the required DC protection. Took me about 3 hours to fit, mainly because the plumbing under the sink inside was done by a kitchen fitter and all push fits so I really struggled doing up the compression couplings with it all waving about. There was a nice pair of flexis on the tap as well.
