Issue with Red Reefer 350 main control valve

[Paleozoic_reefer]

Hi everyone,

For the past month I’ve been having to constantly adjust the control valve to keep the system quite. Every time I find the sweet spot on the water level in the overflow (right below the Red Reefer sticker) it says quiet for a few days then sure enough in the middle of the night I wake up to the flushing toilet sound...any ideas on what might be going on???

I would start by taking the line/valve off. Disassemble and clean. See if that fixes it. Could have a restriction. I have read posts where members just replace the valve all together.

HotRocks, I saw a video online the other day with someone doing that exact same thing! I'll clean it out and see what the issue is and hopefully that'll fix the issue.

thanks!

Red Sea used an iffy diaphram valve for the part and this is something that I think a lot of us reefer owners struggle with. Some people have replaced the stock diaphram valve with a gate valve, but you need to do some research because Red Sea uses metric connections, so you may have to get an adapter. I think there are instructions on this board if you're looking.

Personally I don't feel like messing with the plumbing on my Reefer 450 so I just adjust it every couple of days when it starts to get noisy again.

Thanks KoolAidMan; glad to know this is an issues with other RS Reefer owners!

I slipped a 1 inch silicone hose over the emergency overflow pipe so it effectively raises the pipe about a 1/2 inch. Seems to have taken some of the sensitivity
out of it.
