Hi All

Looking to fit a Jabsco 58500 Lite Flush toilet in place of the original Jabsco manual currently fitted

All the dimesnsions show that it will be a straight swop(?) and will fit in the same place and footprint

My question is electrical

It will draw 20 amps from a 12V supply and a short cable run could use a 4.0mm cable, I would like to use 6.0mm (just because) but will the terminals on the toilet accept the 6.0mm conductor (can't see this info on the technical spec sheet) and will the terminals on the overhead dash board circuit breaker also accept such a large conductor, is there a route for the cable from the dash board above to below the floor in the heads?

Alternatively, is the supply to shaver socket rated at 20 amps and fed from where? It would be easier to get rid of the shaver point and take the supply from there than from the overhead dash

Wish I could go to the boat!
 
Dont know about the electric draw and 6mm on that particular head sorry. But if it is not already make it a fresh water flush while you are doing it a job you will never regret.
 
Plus 1 for fresh water flushing. Have you checked whether you can just buy an electric conversion kit instead of replacing the whole thing? I did my conversion by a simpler means, electric fresh water pump in via a small dedicated pump and manual pump out. It works very well.
 
Good call re the Sealine forum

I've found the cost of the electric conversion kit to be as much as a whole new thing, and the new loo looks nicer, more streamlined and smooth, easier to clean
 
If you change to a fresh water flush should this be taken back to the tank or can it be taken fron the cold water presurised system?
 
I think the best thing for fresh water flush is to have it's own tank, preventing any "feedback"

I'm going with the sea water flush initially
 
I fancy the Jabsco as it should be a straight swop, apart from the electrical connections, and unlike the manual it has a macerator

From the tank via a non return valve then a dedicated pump, which also acts as a non return valve. The reason I have a non return valve just before the pump is that there is a long pipe run from the tank and it took a long dry pump run before the pump primed so I added a non return valve at the top of the uphill bit of pipe just before the pump as the valves in the little pressure pump itself are not perfect.
 
I feel that most fresh water systems are just taken off the sink in the head compartment with an isolation valve (Most are Hepwoth plastic pipe systems) which is always higher than the toilet itself. It is not possible for the flush system to allow water back through so will not contaminate the tank.
It is well worth the investment, it stops the bacteria build up and smell. If you can go for electric you will not regret it. Lee sanitation are a great help with all these systems and bits they have a good web site as well. They are great for advice as well I used them at the boat show before to get spare parts.
 
Agreed, I changed the manual Jabsco pump WCs on my last yacht to electric flush Tecma WCs. Installed a changeover fresh/seawater in case we ever ran out of fresh, never happened. Having nice non-smelly no-effort WCs were a key factor in persuading Mrs Scala to take to the whole boating experience even though some other aspects proved problematic. Hence we now have a Mobo. With leccy / FW flush WC...
 
Fresh flush water from the sink sounds like a good idea, will just being higher than the loo prevent any backflow and water tank contamination?

Am I right in thinking that not all toilets are suitable to take their flush water from a pressurised system?

You don't need to connect the pressurised pump output to the toilet. Just squirt the shower outlet down it and pump out, assuming your shower is on a roaming hose.

We have done that for years since finding sea water flush created a bad smell when left unused for several days .

I guess its not fit for purpose ........or perhaps they are simply protecting themselves against you being poisoned by your own bacteria.
 
Similar query... at present we have the standard jabsco with electric conversion. As noted it's really noisy as in waking the dead when used at night.
Are there any alternatives that are significantly quieter that will fit the same mounting without major surgery - tecma? But which model?
