Sweet Smelling Loo

It doesn't work! (but the blue water looks good) Wait a few days and then see if it still smells sweet then. Stinky loos are caused by dead 'sealife' in the inlet pipe and when you first pump, out it all comes. The only solution is to fill the inlet pipe with FRESH water. I did this with a seperate 5gallon container, a 3 way ball valve fitted as close to the inlet cock as possible & a short length of hose to dip into the fresh water. When you leave the boat you shut the inlet cock, dip the hose into the fresh water and turn the valve to suit, pump fresh water thro' the loo, shut of the 3 way valve and the outlet cock and that's all. I've left for up to 2 months and on the first pump there is NO smell!! Guaranteed to work!
 
Agree completely dickh.

I only ever flush the loo with fresh water - that, combined with replacing a dodgy macerator pump and corroded breather skin fitting, has removed ALL poo-smells from my boat. No chemical treatments used whatsoever. It's taken me long enough to realise it, but I'll never flush with sea water again on a boat with a holding tank. All you do is feed the fermentation process when pumping sea water into the tank. This helps the bacteria in the tank to produce a seriously whiffy outcome.

And another benefit is that there's not much of a whiff when we pump out, too. /forums/images/graemlins/wink.gif
 
I agree as well, don't work and when new I thought the perfume in that thing was way to powerful.
The other reason I got this was to get a bit of chemicals down in the tank, dunno yet if it has made a difference.
 
My Filter thing worked for a while but the smell in the miships cabin is now so powerfull that it makes sleeping in there unpleasant. I spoke to an owner of an identical boat berthed on the same pontoon and he replaced the pipe from the loo to the grey water tank and repiped his supply from his fresh water tank instead of the sea cock, using a non return valve or two. It appears that this is the only way to stop the bacteria building up in the outlet pipe as it is some form of sea creature that causes it. Looks like a job for the rainy bank holiday.
 
We replaced all the hoses, and the macerator to no effect. Then we added a 100lt bladder tank for freshwater flushing and now the bog smells sweet, but the whiff was still there under the floor. Then it started to get worse. It's bilgewater that's gone bad (thanks to Headmistress for the tipoff). I've yet to get round to completely flushing and cleaning, but as an interim measure, the pet odour remover stuff from the petshop works a treat.

Hmm - Headmistress will not be happy at this - I believe the water supply for the heads should be completely seperate from fresh water for food prep/drinking otherwise you run the risk of germs entering the domestic supply.
