Re: Holding tank mystery

Thomas Kleman
 

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.

In the USA, this is a very common home plumbing pipe that can be found in pretty much every hardware store anywhere in the country.  You can also get it on online on Amazon and eBay and MRO sites like McMaster-Carr and Grainger.  Search for "2" Schedule 40 PVC Pipe".

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.

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,

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.

I noticed after our 17 day rather rough ride between Oahu and FP that my aft head flushes very slowly.

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.

I just repacked my rudder stuffing box and found that the same piece of PVC pipe that I use to seat the C-Drive seals works well to help seat the packing material in the stuffing box.  I also used a 1/4" (6mm) piece of hardwood to seat the packing.

Re: New LiFePO4 Batteries for Aquarius

Scott SV Tengah
 

That's a fantastic deal and far less than what I paid for my Victron batteries. If mine ever die I might consider this manufacturer after some more research.

A few things I paid attention to when setting up my system and I noticed here, that might help those of you designing your systems for longevity:

1) For this battery, the recommended charge current is 50-80amps for each 300AH. That's around .16 x Capacity to .26C. Keep that in mind when sizing your chargers. Victron recommends 0.5C, so with my 450AH system, I am running 200 amps of charging into it, below Victron's recommended limit. Battle Born recommends 0.5C also. With an equivalent 450AH system from this manufacturer, it seems you should not have more than 75-120amps of charging. Not a big deal but it will definitely increase your generator runtimes if you don't have enough solar/wind.

2) The maximum continuous recommended discharge current is 0.66C whereas Victron recommends 2.0C. Battle Born recommends 1.0C. For most uses, this is not a concern but be aware if you're maxing out a 5kw inverter and running your water maker, that is nearly 225amps. We have done that on occassion.

3) Someone really should ask or better yet, test to see what happens at low and high voltage cutoff. Does it completely disconnect the offending 3.3v cell and if so, how does that affect bank voltage? Or does one offending cell disconnect 8 cells so that your voltage is not affected? Perhaps it does what Victron does and turn off charging, but leaves the battery connected? This is important because I have definitely gotten a few high voltage cutoffs on my system in the last 2 years. You don't want to find out that the BMS cuts all your power off in the middle of a storm in the event of a relatively common high voltage disconnect.

4) I know Victron's low voltage cutoff strategy is to disconnect the load, not something I would like to happen in a storm. I don't deal with low voltage disconnect the way Victron wants me to, rather relying on the generator to come on and raise the voltage. What is the response in this system?

FYI Mastervolt has even higher charge and discharge limits, so I don't think my system is the "most robust". I do know that MV is much more expensive than Victron and it is what it is, but it's important to respect those limits. I cannot imagine Victron/MV is less conservative with their ratings compared to Chinese retailers, so it probably has to do with the internal connections.

Re: Deck hatch dogs reinforcements

Pierre Blouin
 

Guys, I just finished getting this part made at a local machine shop.  I brought him the sample you see in this picture Bill attached (that was a picture I took). So the machine shop took my sample, reversed engineered a drawing and made a few more for me, it's made of aluminum. Coincidentally, I was just about to come offer to this group a bulk order,  if anyone is interested, just send me an email offline at blouin_dion@....  Depending on the volume, price will be ~ $20 USD each + shipping,

I don't have a picture of the new one unfortunately, brought the new parts on Viva yesterday, about to install them.  I'll come back with a picture in the next few days.

P.S. This is my first post, we bought our SM 6 months ago. We're thrilled. What a great group this is, joined this group over 8 months ago, and have been following every thread since.

Re: Holding tank mystery

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.
