The cartridge is not compatible for this type of diverted valve because it's with bypass pipe. www.screwfix.com/p/baxi-7656807-erp-models-3-way-valve-cartridge-without-by-pass-only/291TP?tc=ET6&gad_source=1&gclid=Cj0KCQjw8pKxBhD_ARIsAPrG45na_KR8zPgnN0dwE6cROfAMfpBTLR-C7h6Ky5MeGB-MVvrTYis8XB4aAnizEALw_wcB&gclsrc=aw.ds

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

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