for ***** sake these bloody toilets

cheers jimmy

this pic of the impeller

I can vaguely remember seeing a part that looked like this but too be honest I thought the chopping blades were the impeller so didn't pay much attention to the part in your picture :o still learning :D

where can I get a service kit that will include the impeller so I have at least got a new one to fit once it is stripped

cheers

Shaun when you strip the loo to inspect / replace the Impellor, I would see if you can increase the outlet pipe size to 38mm to as close to the loo outlet as possible. The longer the 19mm pipe run the more resistance to flow, especially for the more heavy stuff.

I was thinking along the same lines as you here but will it be ok why would fairline use 19mm to a connector then change to 38mm there must be a reason for this if I use 38mm of the back of the loo will it create a too bigger area and the impeller may not be able to cope with the large area and may not be able to force it through as the 19mm pipe comes off the toilet then goes vertical for about 800mm to a connector / u bend the it changes to 38mm pipes and heads back down to the holding tank so the waste gets pumped up hill over the bend and then down into the tank there must be a reason for this or they would just send it down hill all the way from the loo as the loo is higher than the holding tank
 
you're right. A wider diameter pipe will have more gunge to push through to the tank, and also the flow rate will be slower, possibly allowing deposition of hard solids. Keep it to the19mm when you have solved the reason for lack of flow.

The pumps 'Lift' won't change, but the resistance to flow will reduce, so having a wider diameter won't increase the back pressure at the pump. My conversion goes up a similar distance (this is to ensure the pipe can't backfill and sink the boat), I expect Fairline fitted 19mm simply because the outlet stub from the loo is 19mm, and this was the (in-)convenient place to increase the size.

I would say suck it and see, but perhaps not for this thread !

Just had a look at the drawing - it shows a 1"(25mm) outlet, then the exploded view shows an adaptor - item10, that looks like it increases the pipe outlet diameter. I would order an item 10 or contact them and ask for the dimension of the outlet from this part.

What a wonderful thread! Shows how you have to abandon squeamishness if you want to run a boat.

And reminds me of some winter maintenance to be done on my Jabsco electric "silent" flush, namely to replace the joker valve. Happy New Year.
 
I was also about to suggest you contact jabscoshop. Their website illustrates all the different types of jabsco electric toilets together with diagrams and parts lists. They also offer technical advice on 0870 738 8001 or,for trade, 01462 480 380, so might be worth a call tomorrow. It does seem a coincidence that both your toilets appear to be suffering the same problem, which would more likely suggest an issue with the system rather than the individual toilets. However, I have been told in the past that one of the major causes of these toilets becoming increasingly less efficient at flushing until they no longer flush at all is a clogged-up joker valve (number 11 on the previously shown diagram) ,though the usual cause of this is calcium build up caused by using hard water in the freshwater versions. As it happens, the main replacement part of the service kit for the model shown in this diagram is the joker valve. Personally,based on my own experience of having had 2 similar jabsco toilets,albeit using freshwater, for the last 6 years with between 2-4 people spending a total of about 60 weeks aboard with no problem, despite some of the visitors' apparent belief that I own a toilet roll factory, I do think it should only be a short-term problem for you.
 
I think mine is slightly different to this drawing and I don't recall the joker valve mine has the exit from the bowl and fits directly to the s shaped black pipe with nothing in between as I have removed all of this to thoroughly clean it all

I need to get the model of my toilet from fairline if possible then go from there the macerator bit looks the same in the drawing but the base does not have all the other stuff as far as I recall

the more I look into it with the info you have given me I think people are correct in suggesting I change the impeller kits after looking at diagrams I have not seen these as they are behind the chopper blade so need to strip further I think

cheers
 
This toilet does not have a joker valve, the purpose of it on a hand pump toilet is to push the waste into a small size , small enough to go down the pipe and to stop a back flush of sea water into the bowl.

Shawn the impeller is behind the chopper blade housing, you have to remove the chopper blade, then pull off the remaining housing, the impeller blade is behind there. The chopper blade alone will not flush the waste out the toilet its only there to chop the waste.

yes cheers paul I understand this now I have not checked the impeller itself and as you say I bet this IS the problem with both toilets I was mistaken and thought the chopper blades were used to chop and flush the toilet

another full strip down to look forward to for both toilets oh well get it all done before summer then I can enjoy it

cheers
 
As said earlier, sounds like it may have been blocked previously before using it for the last time?

then is forced towards the rubber impeller then down the pipe, I'd say 99% that there will be blades missing off the impeller part no 16 on the drawing, my money is that you still have the impeller in the pump as per the other model shown, its the impeller that sucks away the waste.

It's another strip down to find the rubber impeller .

Hiya, Two more pence worth as I have had the same WCs'. I've been lucky, not had any problems with toilets flushing on my Phantom or Targa, both have worked properly all the time.
I'm with VPaul on this one though, item 16 on parts list and also check for any other accumulated debris around the spindle behind the metal macerator as they pick up fluff and hair etc.

Recently, I had a minor water seep and needed to replace the 'O' ring behind the pump. In trying to lock the spindle when trying to tighten the 2 bladed metal macerator impeller arm, I accidentally snapped off one of the blades of the plastic impeller. (not rubber) I then re-opened the service kit and fitted the other one and she worked fine again. We use any lower quality toilet paper as it breaks up so easily if given a minute to soak. Kitchen role will not go through. How do I know this?

Our main difference is that we use fresh water to flush as this stops any odours when we come back to the boat. We also have a separate fill switch, therefore we are able to fill the bowl manually prior to hitting the flush/empty switch. The standard operation is to flush while drawing in water by impeller vacating space and sucking in more water from sea or a domestic source.

When you're all clear again this is a very nice low cost mod that I would def. recommend. :encouragement:

Good luck tho.

this is my toilet set up

toiletpictureblownup_zpse426dd1f.png


I am going to order 2 x the following no's for both toilets 8,11,12,13,14,15,16

this should cover it for both toilets more shuffling around in small spaces but hopefully worth it if it sort the problem out

I kind of disagree - we've had electric Tecma toilets on our boat and all three have been faultless for the nearly 7 years we've had it - and they've definitely been put through their paces! That said, I respect Shawn for sticking with what he's got and trying to resolve the problem - this can't be normal and replacing the existing toilets would be a waste IMHO. So my hat's off to Shawn - good luck with it :)

Fair enough. I guess that I just don't like the idea of being totally reliant upon electrics and a functioning macerator to go to the loo. :)

On our first boat, a 22' Ballerina (odd looking thing with a large metal pole in the middle and strange pieces of linen - hoistable main engines I then understood!) we had a 'manual flush toilet' AKA a bucket. Even now with two electric loos we still carry the good old bucket, mind you SWMBO is a bit older and apparently wiser now, so not so sure the good old days would necessarily impress her in this regard now, but then on a Mobo having no power likely means we have no propulsion either, so not being able to use the loo would likely be a lesser concern.

Yep, you've got it. Apols for earlier, I said part16 but it was in fact part 13 as pictured with the four blades. The service kit is pretty standard and most shiny shops like Force 4 have them or will get them for you.:encouragement:
Enjoy.

Once you get them fixed, they should be fairly reliable. I've had these toilets for six years with few problems, and we just use cheap toilet paper from the supermarket, so I disagree about the need to use expensive chandlery stuff. They do block if someone puts face wipes or kitchen roll down though, but that's no surprise.

The problems I've had have all been related to scale forming on the inside of the pipes, then breaking off and blocking the diverter sea cock, so not really related to the toilet itself. I notice that the chopping blade on new service kits seems to be plastic, which doesn't sound so good.
