Hi Kevin, is it possible to replace the Pressure Maintaining Section, i.e. the top section which is adjusted to maintain pressure? My unit, Caleffi Automatic filling Unit, Series 553, ( Calaffi 01025/05 GB) is constantly losing pressure. It is not identical to the unit you illustrated, which clearly shows how pressure is adjusted by turning the screw in the centre of the pressure dial and see the pressure one requires. With my unit, one must remove a plastic cap, then adjust a plastic screw embedded in the cavity, which distorts far too easily. I am based in Rep. of Ireland and would appreciate where in Ireland or UK can such an item be replaced? In anticipation of a positive response, thank you for your assistance
My backup flow preventer still leaking. So annoying. Even after changing out to new oem watts Backflow preventer

We have a replacement cartridge available for the 553 autofill. You would have to remove the top cap and pull the cartridge to clean or replace.
