I have a 2 year old Cyclone. I mostly am on full hookup but the few times I was not the pump always worked fine. Couldn't get the water pump to work last time without hook up so I called a Mobil repair place to check it out. He installed a new Surflow pump and all was well. A week later however no water again. Was still at the same site so I call the repair guy to come back. He checked and said that the pump was not self priming. Took the intake hose off and sucked on it to prim the pump. Worked fine again for another week. Moved to a new site in a different state and no no water again. Can hear the pump running but no water. Not sure if new pump is bad and not priming or if hose may be kinked after replacement of pump? New pump for sure is still under warranty but don't want to pay labor to new Mobil repair man. Any suggestions from the Forum Family?
