1992 e34 535i auxiliary water pump

Auxiliary water pump, the one located under heater control valve just broke on my e34 535i, i take it out and plug the hose directly in to heater valve.

Pump was already non functional and power disconnected before.

Drove the car to home, some 20km, heating and temperature was normal, is it good idea to live it without this pump?

Also what are the symptoms if heater valve is non functional.

Radiator was replaced yesterday since the old one started leaking, can this non functional pump be reason for putting too much pressure to the rad too? im afraid of damaging the new rad.

Any help appreciated.
