Dear YoRepareros! How are they? On this occasion I annoy you to ask them about the correct installation of a VF Toilet Valve, the model is 368.01. I understand that the downpipe has to leave the tank directly and has to be 1.5 ''. That's true? The question specifically is the following: the pipe from the tank to the bathroom makes the following route: 0.50mts vertical, then 4mts horizontal, and then another 2mts vertical to where the valve would be. On the other side below the tank I have a Rowa Tango 20 pressurizing pump. So I wanted to know what I have to take into account for the installation and that it works well. Do I go down from the pump? Do I go down directly from the tank? How many meters is good? the height is ok? Anyway, I need the advice of the experts here so that then the water sweeps everything well and not doing all this wrong. Thank you. Gaston
