WC Holding tank

[Daydreams]

My WC holding tank needs replacing as its got a small leak.Its a bag type. I have another bag which came with the boat when I purchaed it a few weeks ago. The only thing is that the new bag has only one moulded in connection. Does anyone know if I can add otherconnections sucessfully?Having said all that, I would much prefere to put a rigid one in there, does anyone know the maximum size I can put in through the v-berth access hatch?thanks

Well I just read and article in one of the boat repair mags. It showed that you could relocate the fittings quite easily. Where you get them I would not know... that being said My S299 has a 2 foot by 2 foot triangular opening(my best guess) and I would guess you could make it larger if needed.

They make TOP quality plastic tank for a very reasonable price and have more than 400 shapes and sizes to choose from--over 100 of which are non-rectangular. And the put fittings in the sizes and locations specified by the customer when they mak the tank. Their catalog is here: http://www.ronco-plastics.comIf you do end up using the bladder (which is not recommended for waste holding), you'll have to install TWO new fittings...one of which has to be a vent line fitting. You can't use an unvented bladded to hold sewage...CG regs require that all waste holding tanks be vented to the outside of the boat.

I've recently outfitted my S299 with a new head and holding tank system. I used a ridged 9 gal holding tank and moved the pumpout up next to the anchor locker and vented the HT into the anchor locker. I did add a subfloor in the area under the v-berth to give it a flat surface the sit on...
