Pipe size from flow master pressurised system

[lynda100]

Hi everyone,
I joined this forum for some professional advice. Can anyone tell me please how far the 22ml pipe should run from a flow master tank on a pressurised system. The person who installed has fitted only 12inches before reducing it - is this ok?

The hot pipe running to the taps?

Might be a daft question but are you actually having problems?

Hi John
The 22ml pipe (12inches of it), then it changes to 15ml, comes out of the top of the flow master and after that goes up the wall and then I don't know. The pressure in the taps is not good. Someone told me it should be 22ml to the first t section is that correct?

To many variables to be honest. What is the supply to the cylinder? What is the supply's flow and pressure? What is the number and type of outlets? What are the pipe lengths and routes?

If the supply to the cylinder is poor it probably won't make much of a difference? If it's good then it probably will make a lot of difference.
