I've two heads on my boat and am considering converting the guest one to electric. Primarily as I have a young daughter who just will not flush manually. I also have the perennial rotten egg smell when it is first flushed.

However I'm far to tight to spend £300 on a new electric one, and would continue to be smelly.

As an alternative I'm pondering taking a solenoid valve controlled fresh water feed to fill the bowl, and fitting a macerator to evacuate. The valve and pump off eBay would be around £60.

I would fit a three way switch so up would fill and down would empty.

I could possibly set it up so I can leave the existing manual pump in place so it could be used to fill with sea water if at long term anchorage, saving fresh water.

Next step may also be a small holding tank for when no2 beckons and the marina loos are just too far.


Would it work?
 
I have a very clean second hand electric loo you can have for £50 plus £10 delivery, needs a small pipe available from chandlers for about £10 and the pump delivers the water, macerates and empties. The pump like you say costs about £60. I can't remember the make, very popular in Australia if I remember, I bought it for £50 from Vyv Cox but fitted a Jabsco electric instead. Like you, the twin reasons were the children not being able to manually flush and the smell, both of which are no longer a problem.

Surely that's ThURD hand? Sounds great can you post a picture of the beauty with model details?

I did have an electric one on a previous boat it work fine but I always got a sense of panic as the water would fill until close to almost overflowing then slowly empty again.

Probably one of these. https://www.whitworths.com.au/main_itemdetail.asp?cat=133&item=89672&intAbsolutePage=1
 
The smell is due to small amounts of waste getting past the piston, in the shared cylinder, into the inlet pipework. The quantity is small enough that it doesn't smell directly, but it sets up the bacteria colonies that do. People say that it's simply stagnant seawater and nothing to do with sewage, but Vyv has disproved this pretty thoroughly with a whole series of non-smelling seawater samples in an experiment lasting several months.

So, logically, the smell should be prevented simply by setting up a new inlet pipe with a separate flush pump, whether manual or electric. No need to connect your drinking water supply to your toilet bowl, which is pretty dubious hygienically and would be illegal on land.

Thanks, so any electric head which I'm guessing relays on separate pumps (same motor?) should improve matters.
For the opaque, fertile water I typically moor in a fresh water feed still appeals. I agree some kind of break in the supply would be needed to prevent the risk of contaminating the water tanks.
 
Yes, the toilet I sold to Lazy Kipper was a TMC. Was working perfectly well when I tried it on the boat we bought. I have now found the switch for it but not available until later in the year. FOC if you want it.

My Jabsco LITE that has no means of sending foul water into the supply side never smells in the slightest.

Toilet identified in the above posts, £50 plus a bit of postage.
