Boat plumbing what a nightmare. It all started innocently enough. During the initial inspection of our Sealine 240 we noticed that the heads sea cocks didn't close. So with the Sealine out of the water for servicing this was an ideal time to get stuck in. Of course the old double walled and reinforced pipes wouldn't come off so out with the knife. 10 minutes later both sea cocks were out. The waste seacock was lined with something resembling concrete so no chance of it every closing again. The new ones fitted easily enough but the hoses wouldn't stretch enough to fit now. Back to the chandlers for some new pipes. Then the first problem reared its head. Despite a lot of huffing and puffing the old hoses running behind the cabin mouldings wouldn't come out and there wasn't enough room to even see what was going on let alone run new pipes. Seems Sealine must have fitted out the cabin moulding before fitting it in the hull /forums/images/graemlins/frown.gif

Whilst ponding this drama I noticed the hatch in the mid cabin which gives access to the fresh water tank. 9 screws later the hatch was unfastened, but wouldn't come out of the berth, simply to big again must have been fitted during the build. However the fresh water tank compartment was a disaster that would do Gludy proud /forums/images/graemlins/wink.gif The tank was sat in 2" of dirty water as was the wires for the shower pump /forums/images/graemlins/shocked.gif Corrosion on the Ali tank didn't look good either. Only one thing for it, out with the tank by cutting more hoses.
Whilst carrying it to the back garden and the hose pipe I noticed the tank rattled. Tipping it up white lime scale chips fell out and the large intake pipe appeared to be lined with a brown slime, yuk /forums/images/graemlins/frown.gif . Filling the tank from the hose revealed the worst. Several little fountains coming out from the seams finalised the decision, it was scrap. Back to the chandlers to investigate tanks. Plastic ones were either to small or just woudn't fit the space available, but a 100 lire flexible tank from plastimo was available at £52. Some new hoses and clips added to the bill. Fitting was simple enough and I chose to secure it in place with two webbing straps although no instructions were given.

The following day meant back to the loo. Since the old pipes would have to be replaced a new loo could now be considered. Some lengthy research on these forums gave dire warnings if you didn't fit £2000 of baby blake toilet, which could only end in disaster. Back in the real world £2000 for a boat toilet was out the question, the trailer didn't cost that much. Two seperate chandlers in Fareham recommended Jabsco and they carried a good range of spares, a good sign ? Cutting the original pipes short and out of the way, the new pipes were rigged though three bulkheads and across the end of the mid cabin. Some pieces of timber hid the pipes from view but now means they are easily removable in the future.


So will the toilet block ? will the flexible tank prove too flexible and leak only time will tell,

Of course the mid cabin is about 3 feet in height, spending 3 days working in there with your hands in through a hatch was great fun. Just hope those sea cocks are water tight when she goes back in. And I suppose the skin will grow back on my knuckles /forums/images/graemlins/frown.gif

Don't talk to me about Sealines and plumbing! Back in 1993, I nearly lost (that's "lost" as in "sunk") a Sealine 255 off Portland Bill because of their crap plumbing!
 
I know the feeling, I had to completely remove the linings & center bulkhead wall to remove the fuel tank from our sealine 240, that too was installed before the deck was put on & has to be removed via the midberth.

Took 3 weekends, 2 days to remove, 4 days to put back, & yes the fuel tank is made from the same ally as the water tank.

A job I dont want to do again.
 
Oh great /forums/images/graemlins/frown.gif I thought the fuel tank came out via the engine bay, however that one can wait until next year. Whats the easiest why just to view it, is that possible?

To remove the fuel tank the inspection hatch has to be removed from the engine bay as well as dismantling the midberth.
The tank has to come out through the midberth unless you want to remove the engine!!!!

It's a pig of a job, the fill & vent hoses are on the port side corner of the tank, getting them off although tricky is no problem but the space surounding the tank is just enough to get your hand in.

Putting them back on is a complete nighmare & that goes for the fuel line which is center top, easy when the fitters installed before the deck went on, all the clips & fittings are pointed upwards because they were put on from above, now the space is approx 2 inches all round.

At times I did wonder if it was even possile to get the tank out, it is, but it's very tight.

If you do smell fuel the tank in set into a 6 inch bund, look in the midberth down the bulkhead, under the berth cushion.
If you see fuel in the bund then it's time for the tank to come out.

I don't have to add that with petrol this can be a very testing time, I hope you will never need to do it. /forums/images/graemlins/frown.gif
 
Thanks for the reply, that can wait until next year me thinks. Just scraping the anti foul off my hands after an interesting day spent horrizontal under the trailer and boat.
