The waterstop connector is causing the problem

I realise that, the P/W instructions do recommend against using one.

replace it or remove the disc & spring.

But I like having the waterstop end so I can switch from P/W to rinsing
with a hoze nozzle without going back to turn off at the tap, and with
care when connecting, it's rarely a problem.

I just fold my hose to stop the water if I want to change an attachment. I find the waterstop valves too restrictive.
