We have a new washing machine -cold fill only. When turning on cold water valve to clean pipes before connection to WM, noticed pressure is very high. This is what it is set at and is now connected to the WM - is this ok? I have no way of measuring what the pressure is. Any help greatly appreciated. Becka (PS - the pics i have attached show that the cold fill is turned to the left - I think the tap is turned full on - although can't be sure).
