A Bit More Advice Te Soil Pipe Please.


Ray

Recommended Posts

In the photo of the diverter valve you can see last years new pipe from the wc to valve on the right and the older pipe I want to replace on the left.

In the photo of the top of the holding tank you can see the pipe to be replaced going in to the tank and running beside it the new pipe to the diverter valve.

It seems to me I could simply cut the new pipe at this point and connect into the holding tank.

This would cut the journey length of waste by nearly 2 metres and remove the obstruction of the valve. It would also remove a slightly uphill section.

I would flush and seal the diverter valve, leaving it in place to avoid any interference with the hull and having it available if some future owner takes her off broads and wants to use it.

Any thoughts or potential problems I've missed please?

What you suggest makes sense if you never plan on using the direct discharge option, If you are going to leave the spare pipe attached to the hull valve I'd be tempted to pump any water out and put a drop of neat anti-freeze down it before capping in case of future bad cold snaps when you've forgotten it's there as chances are a drop of water will slowly get past the valve eventually filling the pipe to waterline.

I'd take the diverter off and make up a pipe blank to put in there, maybe a bit of 40mm plastic bar turned down to 38mm leaving a couple of small ridges convenient hose clip distances apart and push inside the hose and clip.

I just had another look after reading your post. That's good advice, thank you 🍺

Hi Ray if you dont use the diverter valve(ie pump toilet overboard and not going to sea) anything that shortens the length is a good thing , good to see that you have two stainless clips on each joint, ideally the saddles should be opposite each other BUT dont change them now as they are set on the hose but perhaps doing this on the new hose joints.

Thank you John, if I do this the waste hose from wc to holding tank will be about 2 feet long and all on a slight slope down to the tank.Β 

I cant imagine I would ever want to use the facility to pump overboard but with the outlet already fitted in the skin converting her back would be quite a straight forward job I hope.

I'm just about decided to do it, I have to change a pipe anyway and this could even be a (slightly) less unpleasant way to get the job done and end up with a more efficient system πŸ‘

Sorry to ask so many questions but I think I may leave the diverter valve fitted in the boat and cut off short (3 or 4 inches) the current pipes from the wc and to the holding tank and seal them off.

Would either of these items be suitable please - https://www.amazon.co.uk/gp/aw/d/B08155HPJP/ref=sspa_mw_detail_1?ie=UTF8&psc=1&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9kZXRhaWwy&th=1

I have this morning found and ordered some 40mm bar so it'll be belt and braces for me now anyway.

I'm leaving the diverter valve in place which I'm guessing also has some mechanism for stopping water ingress at the point where it would discharge.

So the skin valve, the diverter valve and some good effective bungs in the cut off pipes.

Belt, braces and a fetching pair of garters if you will πŸ˜‚

Seriously I'm very grateful for all the advice from you both πŸ‘πŸΊ

The only things I keep telling myself are that I have to do something anyway and this should make a real improvement to the one thing that would be good to improve.

On the other hand... I can offer volunteers beer, tea, coffee, cake, never ending gratitude, money, my car, my house... a pact with the devil? πŸ˜‚

I could offer to come and watch, but c*cking it up in front of an audience may not be good for your self esteem, not to mention my nose!! πŸ˜‰
