Need a new electric toilet. When purchasing one it says to choose either 12v or 24v....

Assuming it is 12v as when I switch on my DC breaker, the existing electric toilet works.

Also assuming 24v is wired to AC? Could be completely wrong, I have no clue with electrics.
 
what are the electrics on your boat?
12V or 24V?
usually 24V if boat is over 13m (but it all depends)
wont see a sub 10m running 24V and wont see a 16+ running 12V

220-230V is another thing. Toilet will run on the 12 or 24, nothing directly having to do with 220V (except that 220V is typically used to run the battery charger).

V.

PS. to complicate matters more, even a 24V boat will have a 12V circuit to run things like VHF, radio, maybe plotter, etc...
 
Thanks for replies so far.

So, I want to be a hero and fit this new loo myself. Here are my thoughts -

1. Replacing the loo itself should be simple - install new toilet, and rewire with existing 12v cables (I am assuming here, but hoping this is the case)
2. Existing hoses should be ok to use on new loo
3. My only issue - the new loo needs a pump attached to draw in the raw water. I have not installed one before and know f all about electronics. It's 12v, but no idea where to wire it to or what to use. Can you wire it to an existing 12v connection using anything? Any pointers well received!!!

YES

2. Existing hoses should be ok to use on new loo

YES BUT ... ask Jimmy the builder. I would clear them with Acid when you do it. Jimmy had to replace his which was tricky. Also are the hose routings the same and are the hoses long enough. Any I have dealt with have very small amounts of play in them ( assume to stop sag and trapped efluent )

NO

The T40 uses a fresh water flush so there should be no raw water ( sea) and if there was it would smell.

The new WC will have a solenoid that simply controls the fresh water flush water - this water coming from the cold water system of the boat.

If you don't currently have fresh water flush then make sure you do post your DIY fun and games as it will no longer smell when left.

The T40 has raw water flush currently, it doesn't have freshwater.

Correct. OE was raw water flush.

Watch out for hose sizing when speccing your new wc. As you already know, routing new hoses to/from the wc is difficult, so think carefully before buying a new unit that needs bigger hoses than existing.

Reusing the elec connections will probably be ok simply because the existing unit is already quite a heavy consumer. Worth checking the requirements of the new unit against the existing, in case wiring (unlikely) or breaker need to be uprated.

The wiring itself is a bit tricky to get at - you need to remove the cupboard liner from underneath the basin (easy) and then you'll find that the wiring tracks underneath the wc pan moulding. On my boat there wasn't much slack to play with there.

Is the existing toilet electric?

By implication, have you already bought the new unit? If so - what did you buy?

In terms of wiring up any new pump, I'd use the existing wc circuit. It is simple enough, although if you're not sure about the difference between 12 and 24v, and ac and dc, then perhaps you might be better getting someone in to assist (I'm not trying to be smartarsey here, just responding to your post above).

Yeah I totally get that. It is a fair point and I will likely do that, or see if I can get someone to show me how, as I want to learn for the future.

Regarding the new unit I wanted to keep it raw water to keep it as the current set up is. Looked at loads of threads on toilets re Tecma and Planus, but it just made sense for me to stick with raw water. I have ordered a SaniMarin SN31 with electric control panel. I looked at it at the SIBS and liked it. The Jabsco quiet flush,out of interest needs a seperate pump now instead of the set up where you dont need one! Anyway the SaniMarin is quieter so going for that.

Just out of interest, why do you need a new one? A simpler solution will be to but a manual to electric conversion kit that contains all the components necessary to overhaul your old one.

Hi Pete, the existing is electric. A Jabsco Quiet Flush, but its completely packed up now. So replacing rather than repairing.
