Hi
This wouldnt fill with water. so disconnected fill hose to release pressure, then filled ok just once.
Checked pressure chamber & hose etc, all ok
So you can get it to fill by releasing the prssure chamber , then stops again
Would this be a fault on the aquastop ?
The aquastop is causing it but it may be doing what it’s intended to do? Check when the side chamber drains into the sump and cocks the ‘float’ that the water runs through quickly enough and doesn’t overflow into the small chamber to the right of the float chamber.
If it does it will cause the aquastop to operate, which means the hose or where it fits to the sump is partially blocked 😉
What I meant to say is , I switch the tap off & undo the hose, then put it back on etc & its fills ok, but only once
The pressure chamber is ok, all clean etc. It was a new one fitted just a few months ago and it’s all still clean
