pump out via deck fitted macerator

[Jamesb4uk]

Afternoon all,

 

After 2 years on a narrowboat with cassette loo's I've now got a broads cruiser with pump out... (will still carry a porta potty!!)

 

Question is - I'm currently moored at tidal Medway Bridge with no pump out facilities - they all use sea toilets here - Allington's the nearest pump out station.

 

Can I construct/buy a macerator pump concoction to suck out from the tank deck connector overboard rather than rip out he current bog, fit a sea loo & under water sea cock outlet?

Dont most (domestic type) macerators use lots of water to do the flushing plus dont suck but are installed at the same level as the supply & push?

yeah in in built systems I believe they do.

 

the bowl I have now goes straight into the tank, so no pump/macerator inside the boat - what I'm thinking if possible is to do a external one fitted to the deck connector.

 

if not its just an excuse to go boating I suppose!

I know one boat which has a macerator connected at the bottom of the tank, pumping to a normal pump out fitting on the roof. A screw in adaptor takes a hose,

I'm not sure if it would work with the macerator outside, though, as it might be difficult to prime the pump..

I think all you would need is a 1" diaphragm bilge pump attached to the tank. This is standard practice in France for boats with a holding tank - there's no pump out there.

 

Everything goes to sludgy liquid quick enough just don't put toilet paper down the loo.

 

T-off from the main output pipe and go through the pump to its own skin fitting 6" above the water line.

Standard pump out kit fitted inside boat and short pipe fitted to the out put fitting. Toilet paper dissolves so no problem

Thanks all,

 

might go with the pump out kit inside as it keeps the gunwale free...
