You should use the monument spanner 🔧 22 - 15 mm nuts 🤩

Just replace the cartridge and happy days

The cartridge is not compatible for this type of diverted valve because it's with bypass pipe.

Just wondering why you took the whole block out, i thought you could unscrew the top of the diverter valve and screw in a new one. Im no expert its just what ive seen being done on other channels

The cartridge is not compatible with the tree port valve with bypass pipe.

@@bheating ah OK got you, thanks

[@leebuchanan8194]

Plus if its snapped you change entire lot anyways,unless you can fish bits out

[@davecavaghan7889]

why didn’t you source a compatible cartridge for the boiler model/ serial number

[@bheating]

For diverter valve with bypass there is no cartridge replacement awalaible.

I'm sure there is, seems like a tough job for a simple cartridge change
