What is the maximum loop length?

The maximum loop length of 110 m must be used in all installations. It is not advisable to make the loops longer than 110 m. The reason for this is due to the head pressure from the pump, the pump used is only capable of pressurising water through 110m of pipe. 110 m of multilayer pipe will cover an area of approximately 25 m2. A useful note is to always take the feeder pipes into account from the manifolds.
