Rinker 342 bathroom drain pump

The automatic drain pump on our 2003 342 will not shut off after a shower.  Any idea on how I can fix this?

Check the float switch

Also the drain is not keeping up with the water.  Does anyone know how I access the drain pump?

The shower sump is under the aft bunk port cushion. There is a screen to clean in it. The float switches can/ do go bad. Likely gunky in there and it is sticking. 

Looks like this.

Thank you!

Replacing it is only $70 and 30 minutes of work.  If it's the original from 2003, you got your money's worth out of it.

None of the new shower sumps fit in the location though. So unless it is leaking, replace the float / pump as needed.

Agree that you should replace the pump at the very least, if not the whole thing. BD is right that it's a tight fit. I replaced my original with this Atwood box last spring in my 06 342 and it did fit, tight but it fits:

I needed to replace mine on my 242 last year. I couldn't find a new one that would fit. I also couldn't find a pump that would fit. I ended up buying a new unit and modified everything to fit in the old box.

Good find Liberty. I was hunting for one last week. Got mine working again with a good cleaning. Redoing how it is held in place today. Tired of the 8 screws holding the box down pain.

Agree getting it screwed in is the major pain. My original had an l bracket screwed in to the side opposite the hoses to help, it was screwed ans caulked right in to the tank.

I cleaned out the screen.  Hoping this will fix the problem.  Thanks everyone!

My fix to hold it down and much easier to clean out too!
