Hi there,
I am making connection to the backboiler on a Rayburn. It has 1"BSP female threads. I understand I need to use male BSP iron connectors with fibre washers.
I need the flow pipe to exit and immediately turn a sharp right angle downwards, in order to avoid part of the fitted kitchen. I do not have room to use a compression fitting and bend the pipe, so I propose to use a 90 deg BSPM to compression. However, how can I ensure that it will end up facing the right direction when tightened?
Two proposals which occur to my non-plumbers brain, are:
1) To pack the thread with additional washers until the angle is correct. I suppose it is possible, knowing the thread pitch to calculate the washer thickness required to rotate a required angle?
2) To thread a backnut onto the male thread before connecting to the boiler, and use it to tighten the fitting once correct angle is achieved. Concerned this may leave me with insufficient thread to make a secure connection between fitting and boiler.
I look forward to more experienced replies.
Many thanks
