Seriously, you don't think I know what voltage my boat runs?

Jaysus. Please stop posting on this.

I was commenting on what they (Sealand) designated as a "series."

I hope you looked at the labels on your DC equipment to make sure you have a 32v system.

To the OP, do you have a resolution yet that you can share?

Our 400 MS has a macerator ball valve AND the overboard has a ball valve. Are both open?

It's ten o'clock, do YOU know what voltage(s) your boat system is?

My pump wouldn't prime and the pump was new. I filled the tank about 1/2 full of water first. The tank was plastic so I drilled a small hole in the top and used my inflatable pump to pressurized it. After a few minutes it pumped it out. Then I put a plug in the small hole I had drilled into the tank. I was surprised, but it worked.

I've owned mainship before with same problems.
1) check through hull from inside boat after you take inside hose off of seacock. Open valve slowly on seacock and see if water comes in. If it does, go to 2.
2) attach hose to seacock and replace both hose clamps with new ones. Open sea cock again and sea if water comes through hose between seacock and open end of hose. This is where my problem was. At first nothing happened then slowly I got a slow poop sludge coming at me. I let it go into a bucket until clear. Yuck.
3) attached end to my brand new macerator after I had tried to rebuild old one. Don't waste your time rebuilding. The gaskets are crap, I discovered a threaded rod and nut broken. Big mess and waste of time. Few bucks more you get new one. Keep a spare with you.

Always have diver keep your through hulls open and barnacle free.

Also, I could not get 1/2 full tank to pump out but full tank would. When the plastic tank bulged, I flipped on pump and pushed down on top of bulging tank and away went trouble down the drain.

You having a bad day? Thatís a pretty snarky response to someone that is kindly offering you information that might be helpful.

Might not apply to you, but the next guy reading it might need that info. FWIW, there are boats (mine included) that run both 12 and 24 volt equipment (and 120v and 240v) so its not always so obvious what the voltage would be for a specific item or system.

See, you just learned something after all. You can thank Peggie for that.

Too funny.

Yep, mine is 24v and 12v (electronics). Has been since I bought it too. Go figure that I knew that.

But given I have been boating since I was eight years old and having owned my own boats since I was 24, I found the comment condescending and insulting.

Note I said I found it that way. You or anyone else didn't have to, that's fine with me. And I am sure Peggy, who I have been communicating with for over 20 years, can hold her own corner.

Now I look forward to see what the resolution was, to see who nailed it.

hi,

vacuflush is upstream of the holding tank. it doesn't care what kind of pump you have emptying the holding tank. as an aside i think the vacuflush system uses diaphragm pumps.

we switched to a diaphragm pump on our holding tank 13 years ago. all winters spent in bahamas where there are no "pumpout" boats. it has never failed. it's worth every penny.

I find the best solution is gravity. Mount your black water tank above the water line and just open the drain valve to empty.

Right on! Thats what we did. I moved my tank to the middle of the salon. Gravity takes it away. Only down side is we trip over the tank as we walk around. Thinking about making it into a coffee table.

thought i posted this but i guess i'm imagining things.

vacuflush is upstream from holding tank and has nothing to do with pump used to empty holding tank. btw, i think vacuflush system uses diaphragm pumps.

we replaced our macerator 13 years ago with a sealand diaphragm pump. all those winters were spent in bahamas where you live or die by being able to pumpout. never failed us and worth every penny.
