Replacing a Jabsco manual toilet

[crossy]

Hi All,

Looking for some advice for replacing a Jabsco manual toilet with an electric equivalent in a Sunseeker Portofino 400 please (and before anyone asks why, it's a SWMBO'd thing).

I had originally purchased the Jabsco lite flush, primarily because it has the same footprint as the old manual, but unfortunately when I removed the toilet the old bolts sheared. Rather than using self tappers into plywood Sunseeker seemed to have glassed some threaded steel into the base which have, over time, reacted with the bolts and corroded solid.

Rather then trying to drill out and re-tap the old bolts I subsequently purchased a Jabsco quiet flush raw water option as an alternative which I was going to install yesterday as it has a different footprint. However, upon opening the packaging I noticed that the waste pipe is only 1" ID which looks awfully small (I believe human urine reacts with sea water and calcifies and I don't fancy regularly replacing the waste pipe....).

I have looked around at the better quality options (Tecma etc) but unfortunately it is being fitted into such a small space (180mm max depth footprint) that nothing else looks like it will fit, with the possible exception of the Sanimarin Maxlite.

My question is therefore, is the Quiet flush with it's 1" waste pipe a reliable toilet or should I be looking at alternatives? Does anyone have any experience of the above toilets or are there others which could be options?

Thanks in advance,
Andrew

We have had a Quite flush for two years now on our school boat, works well, no issues, we had a lite flush before but that died and the parts weren't available so I would not use one again.

I was told by our mercan loo guru that the 1 inch outlet pipe gave additional velocity to the product transiting to the holding tank.

the outlet calcifies when not enough water is used to flush out efluent.
umpteen strokes manual, or easy with electric, just use lots of water to flush.

The 1" pipe is all that is required as the loo has a macerator. You will find all macerator outlets such as those used for pump out holding tanks are 1". Same with a macerator household toilet - no need for large bore pipes.

You get a 1" to 1-1/2" adapt or in the kit so don't need too much 1" pipe before it goes into larger pipe, the problem is often what's flushed can block up impeller, once it's in the pipe it's away ok.

Great, thanks for the replies.

In that case, I'll stick with the Quiet flush then and return the lite Flush.

Thanks all for the help,
Andrew
