Re: Holding tank mystery


 

Thomas,

A few more ideas:

Maybe the vent is blocked at the deck cap. You can eliminate this possibility by opening the cap to see if there is any difference.

And, did you check the voltage at the pump?

Of course, it could be a not-so-good or a bad pump.

Tom,

 

A couple of after thoughts:

 

Is the chopper plate and the centrifugal impeller securely fastened to the motor shaft and not worn? And, is the macerator housing oriented correctly? There is also a seal housing in that same area. If the lip seal or o-ring is worn, the pump will suck air into the system rather than move black water.

 

 

With best regards,

Tom,

 

Welcome to FP.

 

Can you clarify, please. Is it the water coming in, or the water going out? I assume by removing motors etc. you are having trouble with the water leaving. If so, have you cleaned the through hull from outside of the boat. Perhaps you picked up some critters along the way.

 

 

With best regards,

 

Mark

I noticed after our 17 day rather rough ride between Oahu and FP that my aft head flushes very slowly. OK, no big problem (not my first rodeo), so change the hoses (clogged), use my drill driven auger on the fitting and.......only about 50 pct better and not nearly the speed of the bow head. Next I break out the medieval tools, pipes I've sharpened and cut to length and I can now make contact with the top of the holding tank from the bottom of the fitting (with a big pipe)...ie. there is no blockage. Better, but still not overly fast. New macerator motor, new hoses, no blockage in fitting......not sure what to do next. If I damaged the copper pipe fitting on its way up to the top of the tank, it wouldn't effect flush speed (I think ?)
