I have Symons Callie SLW-7112-RP faucet and recently there is a water leakage on both hot and cold water. It is clear that the valve cartridges need to be replaced. I followed the instruction and replaced the cold water valve cartridge. But at the hot water side the cartridge seems stuck and can't be removed easily. I attached few images to show the situation.
- above is the cartridge without the handle ad cap
- above is the instruction guide shows that the cartridge is screwed into the control valve and this is the stuck point, I can't remove it out from the control valve. I have used WD 40 and no help
- above just shows that the instruction says how easy to remove the cartridge from the control valve base. I think I need some tool to hold the base. Currently when I turn the cartridge, the whole parts is truing.
Any suggestion or recommendation on tooling is appreciated.
