Freshwater leak while on city water.
After hooking up to city water I noticed a leak from the freshwater tank opening after applying city water pressure.
I wish I could remember where I saw this trick, but it's a simple fix if the problem really is a little bit of debris in the pump system.
First, shut off your city water and switch on your fresh water pump.
Next, run a combination of hot and cold water at your kitchen sink faucet for about 15 seconds and shut off th faucet. Then repeat that process half a dozen times.
Then shut your waterpump off and restart your city water.
This little trick worked just fine. Saved me from thinking then I might have to replace the pump.
Hope this helps someone who has the same problem.
