Appears I had something in the freshwater tank or line to the strainer causing a slight blockage. I put air pressure backwards from the strainer into the tank and now I’m getting full pressure back. Little concerning since the tank and hoses are under the teak floors with no access I see. My mechanic is advising my 2 pumps are for added / consistent pressure and redundancy. I did run the tank dry this summer. Maybe picked up something on the feed tube. Hoping this keeps the problem away. Thanks for all the input.

My 2003 3800 runs all freshwater systems without pulsing with either pumps 1 or 2 and without the need to actuate any valves manually.

On my 2003 38 Open if I only run 1 pump and open the kitchen faucet fully and use bathroom shower at the same time the pressure fluctuates somewhat based on the pump used. When I use both pumps the pressure is constant, no fluctuations.... M2C

Forgot to post the fix. Turns out when I ran the tank dry I must have gotten crud somewhere in the line before the screen filter. I used an air compressor and blew air back into the tank. Cleared it immediately and no further issues. Not sure if the tank pickup has a screen on the end like some fuel pick ups or if it just got caught up on a bend etc. But no issues for the last 2 weeks.

What would be a good replacement for the Flo Jet 4305-500? Several have mentioned a stronger pump.
