Sorry late getting back. as janpcs said it doesnt matter, but when you look at the recurc. pipe needs to be at lowest point to have plenty size for the silicone pipe. As far as cold water in, in a counterflow fashion over the pipes for cooling.Red pipe (hot) out doesnt matter. take care. Bri
I think you are using it upside-down. The hose connected to the pump pipe and the hot side exit should be upwards.
Do you think that it makes any difference? Maybe it's easier on the pump?
you may have a point on that m8👍😁
