I have a 18.57.9 and I've already done a dozen mods to get it to what I call, operational. One I'm yet to figure out is the lack of mains pressure into the van (particular for the internal and external showers). I have good mains pressure but this does not convert to good pressure in the van. I can understand having restricted pressure from the tanks but mains I thought it should be nearly the same (maybe a little less). Does anyone know if there is a pressure valve or a inline 'water saver' restricting flow (I've looked)?
