This question is regarding Aqualisa Multipoint Pink Combi Boiler Cartridge with Gasket - 022802

Kitchen flooded after changing boiler

What Aqualisa cartridge do I require for the Junior 28i Combi boiler installed April 2015? In 1995 Ferroli boiler fitted. Shower fitted with 2 cartridges since. Took out Grey Cartridge, this week, because; leak behind the shower control & tiles, (Removed 2 large tiles) which was soaking the wall. Suspect; that is why the kitchen floor had flooded. The floors have dried out since I isolated the shower and cut the supply for a week. The flooding always seemed to happen between 1am to 9am. Read somewhere that is when the water pressure is higher. How would that impact on the shower supply to leak more? Your website has been very informative, and suggests; that the 022802 pink should be the cartridge for the new Combi boiler. My Aqualisa has all chrome fittings - shower head and rail. Do I need the cartridge with the chrome screws? Are the chrome screws plated on brass screws? Because I would not want to fit brass screws in case they break.

The use of grey or pink cartridges is solely down to the function of the cartridge at different pressures. A correctly fitted cartridge , whether pink or grey should not leak.

The screws in with the chrome finish are the same screws used with all the cartridges , but with a coating. These are used mainly for aesthetics.
