Hi scroggin........thanks for the help, I'll check out the specs of the pump
is 1400 L/H a lot of movement of water?
I did see something on youtube about these valves helping to back up water so that it could be directed to higher places, for instance the water will go to the lowest point but this chap I watched installed a ball valve and was able to back up the water enough to feed a higher water fall first!
I'll do some homework on the pump and just have a fiddle, it may be the perfect pressure without needing the valve but will see.
