I have a refrigerator that doesn't drain on my 2004 310. At first I looked for a Y valve and there isn't one. I've gently tried inserting a probe into the drain with no luck Is there something else I can use to resolve this?
The stock plumbing for the C310 uses a Y for the shower sump and reefer drain (no sump for the reefer-it's a direct connection). That normally goes to a dedicated thru hull. I'm pretty sure PaulJ made the modification teeing the sump outlet with the head inlet himself. It does eliminate a thru hull.Why in the world would you tie something as simple as an icebox drain to a sump into the toilet flush water inlet plumbing?? Or into the toilet plumbing at all???? Rube Goldberg (look him up if you're too young to know who he was) would have loved you!

This was the setup on early models. Later models put the pump and the Y-valve under the head sink. So look for where the Y-valve is located. You will need to turn the Y-valve to the proper side, open the through-hull and then push the shower sump button above the head.Spellman66: the Y valve should be on the right side under the galley sink. The filter and pump are also there.
Catalina keeps us on our toes. That also explains why somebody else had room to put his battery charger under the galley sink-right where my pump, filter, and y-valve are mounted.This was the setup on early models.

Good luck and fair winds.

Picture shows the Y valve on the right. Looking forward, from aft, rotate valve fully clockwise. That puts it in the reefer drain position.
Open the head inlet water seacock (picture #2, looking aft, valve on right). The water exits through that seacock. Turn on the shower sump switch on the main power panel. Push the shower rocker switch above the head. It can take several seconds for the pump suction to pull the reefer water through the lines into the pump. You will hear an audible change in the sound of the pump. View attachment 156775
Interesting. I was wrong about you making that change, must have been Catalina. Maybe they moved it from the galley to the head so shower was the shorter section of tubing, instead of the reefer? So you’ve only got one thru hull under the galley sink?Seems you also have the same RUBE GOLDBERG design as I.

One through hull under the galley sink is correct.Interesting. I was wrong about you making that change, must have been Catalina.
