I just wonder if any one has a copy of the drawing of the big boiler Tich , or a photo copy . Only the boiler details are needed , the drawing in the book is a bit small for my eyesight !!!!!
Hi, can anyone tell me the working pressure for a 3 I/2 inch Tich so I can get the boiler tested? I think it's the large boiler but pressures for both small and large boilers would be much appreciated.
