Hello, so I’m changing over to a cassette toilet and am hoping to get rid of the pump out system or at least some of the parts. It seems a shame to chuck it al as it’s all in working condition! Does anyone know of someone/ a company or something that might be interested in taking it? Thanks!

What are you selling?

Toilet? Maker/model? Condition?

Tank? Size? Material? Condition?

Other parts?

For sale as a whole or are the parts available separately?

Already dismantled or would the buyer have to do this?

Where to collect from?

How much?

Great decision - you'll never look back.

Yes, and throw the kit away and save any other boaters from fitting it.

I gave mine away because I wanted it gone quick - plenty of people wanted it. Within a couple of days someone came past in their boat and picked it up. Much easier than organising transport to a local tip if you don’t drive…and then having to carry the tank and toilet around. 
 

I used Facebook Marketplace, seems to have pretty high traffic for boaty stuff!

Have you seen the "For Sale & Wanted" section on this forum?

 

That's probably the first place I'd list it.

 

I had a pump-out on my first boat so I've lived with both and I'd always avoid them. But like everything else it's a personal choice and some people prefer them.

On a price/visit over the life of the loo that could make for a very expensive 'spending a penny'!

It was  25 years old when I sold it so less what I got for it that would have been  about £170 a year or 20p a day between 2 of you that's not so bad.

ETA it came as part of the boat I didn't fit it. Only reason it went was the tank perforated

The longevity of the tank was my only concern with our pump-out system. Much preferred that to using elsans (which we are familiar with from our campervans).

Curiosity:  When (too-thin) poo tanks perforate, don't they do so at the top?  I have the idea that the parts of the tank that are immersed in the gunk do not corrode anywhere near as fast as the inside top, which gets a lot of condensation.  Is this true or am I imagining things?

Yes it was the top in my case.

I could have put a new top on but just not worth the hassle as the rest of the tank was in  unknown condition after 25 years.

I would probably never have noticed if I wasn't being lazy and delaying the time for a pump out by a  day or two.  I noticed a smell and found there was a damp patch on the tank with some rust round it.........

What I got from selling the toilet paid for the cassette system and some.😎

How thick should they be?

 

When I was moored at Cogenhoe a neighbour bought a boat from Whilton with a dump through pump out tank which was perforated at the top. I don't know if it was Whilton's boat or they were acting on behalf of a seller. The problem had been identified pre-purchase and the broker said it would be fixed. Much later my neighbour found it had been fixed by sticking a piece of ply onto the top of the tank with mastic! 

 

Anyway, mild steel pump out tanks illustrate short-term thinking because at some point they will corrode through. Any boat builder or fitter who does this is cutting corners & costs, while any DIYer who does it on their own boat should probably be aiming to sell within 7- 8 years or so...

Other than cost, are there any objections to an HDPE black tank? They wouldn't corrode, but do they have a good service life?

I've thought the same. A bit like the benefits of Shaun's HDPE NBs, it would be lovely to think that your poop tank was never going to rust through.

Since underground drainage pipes are HDPE I would suggest it is a material that has more than adequate chemical  resistance.

Both my grey and black water tanks are built into the GRP keel on my cruiser - that should never rust thru' either.

My Liverpool boat had a HDPE black tank which sat above the floor, boxed in by the bathroom with a drop through toilet on top. Worked as well as a pump out could work, the tank was remarkably thick and heavy when I removed it.

 

Have heard of larger ones under double beds in wide beams splitting though, but that might be due to poor installation.

Thank you, I can see why they use mild steel for black tanks, both stainless and plastic are expensive, making the whole installation costly to fit, and more to expense to pump out. You have to pay for the convenience of not having to empty a cassette.

How does the material of the tank affect the cost of a pump-out ?

Probably being dim, but why would it be more expensive to pump out? I can see the thickness of a plastic tank would reduce its capacity a little - and therefore reduce slightly the time between pump outs - but why more expensive?

Are the grammarian, let me correct it for you, so that it cannot be misunderstood.

 

.....and more to expense to pump out.  Will that do?

 

I suppose not, there is an additional expense, with a pump out when you pay to empty it. Will that do it, for you?

I'm still puzzled. Do you mean it adds extra (unnecessary) expense to the overall cost of retrofitting a pump-out toilet system.

Ok, you were comparing the ongoing cost of pump-out Vs cassette toilets. I had taken myself down the wormhole of thinking about HDPE toilet waste tanks Vs mild steel tanks.

I think he means that a plastic or stainless tank will be more expensive for the initial fitting, and then there is still the pump out charges that he feels are expensive.

 

I suspect a cassette fan who pays nothing or very little to dump.
