sealand electric toilet

We're on the road on the way to Nac.  Our electric toliet is intermitant, refusing to flush and then working fine.  When it does flush, we hear the sound of a pump which goes on for a long while and sounds like it's pumping dry.  We haved serviced the ball with toliiet seal lube.  Any ideas??

Larry,

Spray everything electrical, circuit boards, switches, connectors, etc. with CorrosionX.  If corrosion is the problem this will clear it up overnight.  Probably will not kill the corrosion instantly but will definitely do so overnight.  Could certainly save you some service cost.

CorrosionX can be sourced at MOT, Xtreme Paint and Graphics or on the web at CorrsionX.com I believe.

Works great to lube moving parts too and on all other electrical items in the coach.

When it does flush, does it put water in the bowl showing that your pump in not pumping dry?
What model toilet is it?

Is it a vacu-flush, by any chance?  If so, have you replaced the duckbill valves and the seals recently (or within the last 3 years as per the maintenance schedule)?

(The vacuum generator for the vacu-flush looks like this, so you can tell if you have one)

We have a vacu-flush and Steve is quite familiar with portions of it.  We'll be in Nac sometime tomorrow afternoon (at MOT) if it's that style and you want to pick his brain.

The toliet is a  sealand 3058 and has the pump shown in Michele's picture.  It fiils with water when it feels like flushing. I've noticed air escaping around the toliet ball so I assume we have a problem with vacumn loss.  We just got the coach and I doubt there was any service to this system.  It probably needs some attention.  Is there anything remedial I can do out in the boonies?  Thanks for all the help, I'm g :)oing to p/u some CorriosionX, sounds great

We will be at FT on 3/19 for 3 or 4 days.  Hope to see everyone who is making the scene.

If the air escape is around the ball, the ball isn't sealing well.  Happens at times, we've found especially after use with hard water. 

Get yourself some paper towels, maybe a little liquid dish or hand soap if you want, rubber/latex gloves if you're inclined.  Pull the ceramic cap off the back of the toilet - you'll see a circuit board with some toggle switches.  The switch settings SHOULD be shown on a piece of paper, possibly on the underside of the cap. 

Put the toilet in service mode with the appropriate switch.  This should open the ball.  You may need to depress the flush level as well, or even experiment with a few combinations (it can be finicky).

Once the ball is open, put on your gloves if using, take your paper towels, wad them up, dampen them with water and use soap if you like.  Now clean the surface that the ball seats against, especially the rubber seal itself.  Clean the ball edges as well (as best you can).  Do take care not to scratch the surfaces (or drop anything down the plumbing).  Take it out of service mode and see how it works (again, this may take some combination of returning the toggle to operate mode and depressing the flush lever).

It's a good idea to carry a spare ball and ball seal with you, just in case.  Every 3 years you're supposed to replace the 4 duckbill valves, ball, and ball seal IF you're using the unit a lot.  We went a bit longer than that before doing so.  The ball seal and ball aren't too bad; the duckbills are inside the vacuum generator pump and tend to collect "material".  Not an extremely difficult job, just somewhat unpleasant.

I'll see if we have the manual in .PDF format and have Steve upload it here.

Yes, these toilets do take more maintenance, but the flushing power is well worth the effort.  These are apparently pretty common toilets in marine applications.

Thanks for the ideas, we tried them out with some success  The toilet is still occasionally inop but you can use the service function in a pinch to get things movin.  The manual is great, much more detail than what was in our box of coach info. Again, thanks.

Larry,

If the toilet won't flush because the leak in the ball seal has pulled the bowl dry (pumping sounds and red "do not flush" light on the indicator panel), add water to the bowl (manually - pour it in) so that the pump has something to pump against.  If the leak isn't too bad, the pump will eventually pull good enough vacuum and the green "ok to flush" light will come on.

Your black tank will, of course, fill up faster having to do this, but it's something you can do if needed.

Around here most of the Vacu- Flush units are being replaced. Last year I replaces the two Vacu-Flush toilets on the boat with  Tecma Silence Plus units due to the high maintenance of the Sealand units. The Tecma  pushes the waste keeping the mechanics of the system out of the waste path. getting rid of vacuum generators, duckbills, seals and working in the mess when things do not flush.....

Only a couple of engineers could get excited about a toilet, BUT this is interesting, since if we could get rid of the vacuum generator we'd have the space for a water softener....

Will have to look into it further and how challenging it would be to replumb....  Our black tank is not directly under the commode, hence the need for the current VacuFlush.

Michelle,
I am sure Steve could work out the pluming. all components are located inside the toilet. so all you have is hose/ pipe to the holding tank. It is over 30' from my forward head to the aft holding tank. we used 1 1/2" Trident Sanitation Hose.

 We seem to have minimized the problem by doing the following (which I admit is a shot gun approach). 1. we continued the use of Thetford toilet seal lub( Camping World). 2. Sprayed the seals with CRC heavy duty Silicone spray as suggested in the toilet manual.  3.  Fill the bowl with water as required.  We only have a failure every 10th time or so.
