How to access shower sump hose on Catalina 310 for replacement?

My shower sump is no longer working. There is no suction. I've cleaned the filter. The pump makes a noise, yet it won't drain the shower sump or the refrigerator when the Y valve is set to that position. On my 2002 Catalina 310, the shower sump hose runs from the sump to a Y-valve under the sink, which is shared with the refrigerator drain hose, and then to a seacock under the sink. How would I access the drain hose from the shower sump to the y valve if I want to replace it? It is an original hose.

I have the same setup, your hose is probably ok. If the fridge drain also doesn’t work, then I suspect the gasket on the filter is the issue. That’s what happened with me. I went to the local hardware store, found a similar rubber ring and trimmed a bit off so it would fit. Has worked for a couple of years now…..
Good luck.

Thanks! I will give that a shot.

So where is the filter? This is a new one for me and I lost suction too

Going to the boat in a couple of hours, will take pics.
my filter is under the sink, beside the y-valve. It is clear with a metal screen in it.

Pictures…. The filter is the 1st pic. There is a gasket available, for a couple of $$, but with delivery to Canada I didn’t do it. Cheers
