Hey guys , here's the problem I have ... I live in my 32ft trailer in fort mcmurray where temperatures can dip below -40 Celsius .. I have all my water lines heat wrapped also my trailer is skirted in with 2 heat bulbs going underneath .... Now normally the water works fine but last night the temp. Got down to -32 ... In the morning the water wouldn't work .. So of course I assumed the water was frozen but I checked all my lines and they seem ok ... Then I filled my holding tank and still no dice . The pump seems to trying to work but nothing is coming out . ..( although when I loosen the intake on the water pump a little water starts sputtering out but then stops ). ..... Anyone have any ideas ?
