I have just remodelled my kitchen and decided to reuse the 2021 model Mondella Credenza vege wash tap. When I reconnected everything the water flow was very low. After rechecking everything I tried removing the non-return valve from the tap. The flow is much better and back to what it used to be.
Do I need the non-return valve? I've never seen one on a tap before and I notice some of the newer Mondella taps don't have them. I must have got some dirt in there somehow and I can't see any way to disassemble it and clean it out.
The non-return valve was connected in the single hose that comes from the tap to the aerator.
