Accessing Shower Sump & Vacuflush Unit

[gratcho]

A couple technical questions about our 2001 350 Mariner

I'd like to inspect and clean out the shower sump; what's the best way to access it? I could not find info in my paperwork.

Our vacuflush head is working fine, but I have a feeling I may need to change the duckbill valves this year (I have them ready if needed). The vacuum unit is visible through a small floor hatch in the stateroom, I'm having trouble figuring out how to service it. Do I unscrew the one fastner I can see holding the unit to the bilge floor and slide it under the opening so I work on it?

Thanks for the advice.

are you saying they didn't provide a hatch large enough???

there should be 4 fasteners holding those compact vac tank/pump unit. on those combo, you just need to detach the pump from the tank (4 screws but only two need to be completly removed, the other two go thru a slot), the unscrew the fittings (inlet and outlet) and pull the DB

but if it aint' broken, dont' fix it!

You're right it appears there must be a trick to this, the floor hatch is about 12" x 10". I can reach in with one arm and reach under the floor to touch the port side of the unit, but doubt I could effectivly work on the unit.

Any advice is welcome.

As far as the access to the sump pump, welcome to the world of Carver. I had the same problem when I had to replace my fresh water pump. I spent hours trying to figure out how to do it. It finally hit me what to do and took me about 1-1/2 hours to do the job.

As far as your head goes, ask your question on the sanitation forum. You will get better results there.

I thought Sea Ray held the the patent on systems you can only reach with one arm!

Not at all. As bad as the access was to my water pump, the aft cabin sump is much worse.
