I had this installed in the summer in our new kitchen extension. The plumber said he had checked it and soon after emigrated to Australia and so is now uncontactable. When we tried to use it I have found that a part on the manifold is missing, so when I open the isolation valve the water gushes out. The part fits into the pipe just below the temperature selector as shown on the photos, and I guess it was mislaid when it was installed so I can't really go back to the supplier. I have tried to contact Polypipe for a spec on the missing part but they were not helpful. I have tried various plumbing fittings such as a half inch male flanged plug but the thread wasn't the same. At the moment my only option is to buy a complete new manifold which is obviously expensive so if anyone has any ideas I would be really grateful. [/list]
