I turn the valve off at the switch and then open the tap and for a fraction of a second water comes out of the tap at mains pressure and then the valve cuts in. If the tap was just open a tiny bit and was dribbling at the time that the switch was turned to off the tap would continue to dribble forever.Â* So just hitting the switch alone will not possible cut off the water to a small leak. The switch needs to be switched to off and a tap need to be turned fully on to force the valve to fully close. However Surestop now claim no dripping taps so perhaps they have improved the design since I installed their previous model many many years ago? Reading between the lines at.... http://www.surestop.co.uk/owners/about/ My Surestop is the original design. It looks as if it was redesigned in 2008 for 0 bar operation so my observation about not fully shutting off unless a tap is fully opened may no longer be true with the later design. Thanks. That was good reading. -- Adam |
