Fresh water gunwal shower nozzle and faucet will not work

Plan to work on line issues tomorrow. Both pumps work. What is interesting is, having not changed out any water lines, the pumps both have reached prime individually and run continuously individually on different occasions. Makes me think there is a water line problem in the line or lines going to the gunwal faucet and shower? The cabin sink faucet continues to work ok.
? Plan to drain fresh water tank and flush out all water lines as next step? I guess this needs to be done on the two incoming lines as well as the two outgoing lines?

I am somewhat perplexed!

Have you checked the in-line screen(s)located just prior to the pump? Had the same issue with mine and the screen was gunked with algae. Cleaned it out and water ran fine.

Also the aerators.

Also the aerators.

Will check. Thanks. Where are the aerators?

Just like in a home faucet - it's the thingy that screws onto the end of the faucet. In the case of the shower, there may be a screen where the hose connects.

Thanks, I will check the things you site. Feel like it is a suction problem given one of the two pumps in the system runs continuously while the other works properly?

I also note that the cabin faucet works irrespective of which pump is primed? Also either pump will prime while the other runs continuously. I am thinking there must be a suction leak in the out going or incoming line that feeds the gunwal faucet and shower? I am somewhat perplexed!
