Check you connections again!

[Dr. D]

As I was going about winterizing my boat, the fresh water pump apparently stopped functioning. The motor was running, but no fluid (the antifreeze I put in the water tank) was moving. I quickly checked the connections and all seemed OK. I decided the pump had an internal failure. As the boat was soon going to be on the hard, I bought a new pump.

On the boat with the replacement pump, I looked carefully over the setup. Looked to be a two hour job and I didn't have the time. So I took 15 minutes to disconnect every fitting, then reconnect them. Fired up the pump and the fluid was flowing. Appears there was an air leak somewhere and the pump was just sucking in air.

Good find and thanks for posting about it.
