Holding tank mystery
|
Thomas Kleman
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 ?)

Power drill with a 9’ length of 10mm rigging wire took two weeks of rotor rooting but now every flush is a delight 🤣. Now I flush 29 seconds every time Cheers Courtney Trippin 54#101

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

Sorry for the incomplete info. The toilet doesn't empty rapidly into the holding tank. The discharge port, joker valve, macerator motor, hoses are all new. The copper pipe going up into the tank is perfectly clear, as is the junction fitting between the smaller and larger hose. I'm totally at a loss on this one.

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,
Mark

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.

Hi Thomas Any chance you changed the polarity of the wiring when you swapped the macerator? I have had a (non-Amel) experience where this happened and the macerator did work but very inefficiently. Dave Ritten

I made a video on how we fixed our toilet who drained VERY slowly. https://www.youtube.com/watch?v=b62ZtpxCPnE&t=5s&ab_channel=Paul%C3%96sterberg Paul on SY Kerpa SM#259 Lagos, Portugal sykerpa.com

Many thanks for the replies and ideas. It ended up being two problems. First, the sanitary hoses and copper inlet tube were blocked. I have a number of tools to quickly deal with that so that's why the slowness of drainage while flushing was perplexing, even after changing everything in the system. The other culprit was my hot wire to the motor having enough corrosion under the "waterproof" connector to reduce performance. Now when you push that red button......stand back three feet...... it's like a jet's engine intake.
