'94 3200 shower drain line after sump

[geoffm70]

Ugh, is there any semantic drawings of the plumbing lines for a 94 3200? I have cleaned out and tested my shower sump and it works perfectly. The drain line from the sump to ?? is blocked/clogged. Does if go direct out, above the waterline like the sinks? Do they have shut off valves? I can't see where the line goes!

I believe there is detail in the owners manual which is located under Documents.

Hopefully there’s enough information to help you figure it out.

The drain line from the sump to out of the boat was and still is somewhat clogged. I used and auger from inside out and managed to get the new sump to pump out once on it's own. After that, I have to wiggle the drain line to get it to work again. Must still have crap in the line. Going to try vinegar and baking soda from the outside in today.

If it’s a ribbed hose I would consider replacing it with a smooth hose.

Not, smooth, clear 1/2"line. How the heck to you replace that?! Going to have to rip apart the mid cabin wall?!

Not familiar with you model enough to answer that one.

Ok. Took a quick look at the manual and based on where the thru hull is located you may be able to access it from the mod-berth by ways of a removable panel. I know my 2400 has one on each side.

Thanks Mike, in the 3200 there is access to the water pump at the bottom of a cupboard in the midcabin and you can see the shower sump drain hose travel under it, but zero access.

update. the discharge line was partially clogged, totally clear now. New sump box installed and then run the shower, and perfect, box fills, the float triggers the pump, water gets pumped over. Perfect! HOWEVER!!!! when the box fills the 2nd time, the float triggers the brand new pump, but the water won't go out??!? I can wiggle the drain hose manually and sometimes the water starts to pump out! WTF?!?

Can you see the entire length of the line? It may have a slight kink in it somewhere.

I got an endoscope camera and it's clear ;o(

I feel sorry for your next patient 🤪

Maybe a borescope 😁

How about removing the hose and installing a new one that discharges into a bucket to see if you get the same results.

Good idea, thanks

FYI, took until yesterday (over a month) but I found access to most of the bathroom fittings. In the 3200, there is a cutout into the behind the bathroom sink wall behind the galley table, seat-backrest.

the sump has a black nipple in the discharge outlet that was creating an airlock.
