New owner for 13' Scamp as of August 2023. Only challenge has been using water heater to heat water. Haven't gotten to work so far. Winterized Scamp per instructions.  De-winterizing now. When fill water in tank and turn on pump, and when connect via city water...all water is draining through outside space where water heater sits. Seems to be coming from top back of space. Not sure if something burst or if missed step not laid out in instructions.  Any help is appreciated!   Thank you.
