Looking for our new boat, continued!

[drverbrian]

The search for our new home goes on with boats being rejected for various reasons. One of these being cassette toilet. I really dont fancy the rest of my life being spent emptying cassettes. I am aware of the arguments about being iced in and unable to get to a pump out and intend to carry a potta potti for emergencies.

 

Finally he gets to the question!

 

Is it possible, and if so financially reasonable, to after fit a pump out system onto a narrow boat? Has anyone ever looked into this or even better done it?

 

Over to you!

[Alan de Enfield]

Yes - do a search for "self pump-out"

 

You will find some very nasty photos, strong words & heated discussions about the rights & wrongs.

 

The problem is finding somewhere to use the system as you can rarely pump-out into an elsan point as the flow is too great, the bowl gets blocked and you get 'blow-back'.

 

Edit - think I may have mis-read the question.

 

Question - fitting a pump-ot toilet and tank, my reading - fitting a self-pump-out. Sorry !!!!

It is possible, but much easier to find a boat that you like with one already fitted.

Yes realize that but it would give us more options!

I think you have probably misread the OP's question.

 

He is not asking about self pump out, but the practicality of changing a boat that doesn't currently have pump out to incorporate it.

We had our pump out changed from dump through to macerator with tank under the bed, pretty easy and we also moved the pump out point and rinser to the top of the boat.

Retro fitting a pump out...

 

problem where to put it so that it does not effect the trim of the boat, fit it to one side and the boat will list at varying angles depending on the amount of effluent in it.

 

where to run the pipe work (large diameter) macerate type

 

Where to fit the outlet for pumping out, gunwale (gunnel) or roof, when fitting to gunwale whether to have two, one each side of the boat. It will always be on the 'wrong' side if you only have one.

 

ps. my boat has a pump out tank across the whole width of the boat and two outlets but it came like that

Having read it again - you are correct. Amended my post.

It's not impossible to retro fit a pumpout loo, but the degrees of practicality vary with each boat, so it's difficult to geralise.

In our boat I designed the main loo to be next to the washbasin with a plastic tank fabricated to fit between the floor bearers - the hull builder knew where the bathroom was going to be - so there was no challenge in fitting the tank.

The rear 'crew's loo' has the tank running under the access stair.

 

We've had no problem with trim in that respect

 

In hire boats we've used the tank was fitted under the bed next to the bathroom with the forward end forming the loo pedestal.

This would seem to be a better solution for a retro fit as - provided there's a space in the next room for the bulk of the tank - there's no need to hack through the floor.

 

Discharge of waste for both loos goes through the roof, I've found that fittings in the gunnel are a pain; sometimes it's difficult to get a goo seal for the vacuum.

 

Another option is to install a macerator loo. There's more flexibility in where the tank can go and the macerated waste can be run through (relatively) small bore pipes.

 

So not impossible or totally impractical, but you'll have be good at visualising each case on its own.

Yes you can retro fit a pumo out and no it isn't expensive.

 

Pick the boat that is,right for you not the toilet it has?!

Why? Edited November 9, 2014 by dekker

[Geordie.narrowboat]

A few reasons.

 

1. We did not like a dump through.

2. The holding tank was small

3. The holding tank was near rusted through

4. We needed to move the hose connector as it was on the side of the boat, not on the gunwhale as ours are narrow gunwales - allowing us to re-site it on the roof

5. The change enables a flat floor

6. The toilet is now at an acceptable level- was too high

7. All this done as we we're rebuilding the bathroom, it needed refurbish anyway

Think that's enough

Oh, we also fitted a tank full indicator
