Hammering pumps are common in RVs Does not necessarly indicate a malfunction, HOWEVER... (Will come back to this) Mine has gotten very loud from time to time epically if the tank is a tad low on water.. Then without explanation it will go dang near silent. (I really have to listen hard) And though I said it SEEMS to happen more if the tank is near empty.. It also happens with the tank is near overflowing.
NOW: I did find one cause one time.. A couple of screws had worked loose on the pump housing, This causes several issues, Running of pump when it should not, Strange pressure issues, and more... Tightening screws helped.
The fact you froze up, Means the pump may have been damaged in this manner.
ONE SYMPTOM.. When I watched the pump, it also SPRAYED water
