Plumbing Help !

[mbird59]

Hi,

This is my first post and I have tried to search the forum but I am unable to find an answer (that i understand).

I have a 30ft x 9ft GRP river cruiser that is pretty much just a shell and I need to plan an entire plumbing system.

Can anyone please advise me on ,or point me at a suitable plumbing diagram. I understand that i will need a fresh water system for a couple of sinks and a shower with the necessary drainage, I will also need a toilet and I guess a pump out system etc.

As much advice as possible would be appreciated.

Many Thanks,
Mick

Don Casey's web page is very good. I have the reinforced vinyl hose that he recommends in my fresh water system. If I was to do it today, I'd probably use the SeaTech system. It's really easy to install.

Thanks very much, already impressed by the great feedback.

Welcome aboard! You'll find this to be a lively group!

I'll be glad to help you spec out the sanitation system.

Am I right that you're not in the US? 'Cuz that would make it kinda useless to point you to the US mfrs and retailers. So where ARE you?

Thought it might be the UK...in which case your best source for everything you need for both the fresh water and the sanitation systems is Tek-Tanks Tek-Tanks - Custom made or standard fit water, waste and fuel tanks . Click on "Boats" and you'll find that they offer toilets, water tanks, calorifiers, hoses, fittings...you name it! You'll want to spend some time on their site, 'cuz they provide a lot of material to help you know what to buy. They should be able to help you spec out both systems. Everything they do is top drawer, so you can rest easy about relying on their advice. If you need more help or have questions about choices, I'll be glad to help you sort things out.

I need to start to plan and install the fresh water system and I am going to use a push fit system (speedfit). It is available in 10mm, 15mm and 22mm I am assuming the 22mm is a bit too big should I use the 10mm or 15mm or does it not really matter.

Thanks.

Outlet number?
Pump type?
etc etc
15mm will do the job. 10 might be O.K. depending on the length of the pipe runs and flow required.

ooooppps
Just read the rest of the thread
A few more questions.
Are you going to liveaboard or is it a weekender. You can get away with a lot less on a weekender.
Do you want a hot water system? There are many ways of heating water
Are you going to be river cruising? Holding tanks will be required. Boat safety scheme will also come into play.

[mbird59]

River cruising and will be a weekender. I have been reading the BSS and have spent a lot of time researching etc.

I have got tanks for fuel and fresh water but have not yet purchased a holding tank.

I also have a fairly small calorifier which will conect fairly easily on to the BMC 1.5 I have.

Having said all that I am sure I will be asking lots and lots of questions.

Thanks,
Michael

Another vote for Pex with the push fit fittings. I did the plumbing on my little boat 4 year ago. Very easy installation which I found a big plus. You can get brass push-fit fittings at many hardware stores. I found the brass fittings worked better for the threaded connections to faucets and the water heater. They seem to work pretty good. Unless you have a big boat 10mm or 1/2" will be more then enough. 1/2" will support 4-5 GPM which is more then enough for two faucets running. 99%+ of the time this will be more then enough.
