After a huge rebuild
on my holding tank/pump system where I replaced everything and made all the hoses a lot shorter by putting them back in the position that they were when the boat was new, I now find the reason that a previous owner moved them in the first place. The antisyphon valve on the holding tank
pump out is about 12 inches too low, the result being that the holding tank
fill up with sea water
. Currently I'm just closing the seacock but would like to fix the problem.
I could put the pipes back to where they were, dont want to, as they snaked all through the boat.
I could raise the whole valve by cutting two holes in the self the sink is in, would work, but will require me then building a cabinet to hide the valve.
OR, and this is the question, can I just lengthen of the duckbill valve unit off the entire antisyphon with a yet to be designed extension tube, that way I dont have to cut into my sink shelf and can snake it up and around behind stuff.
Dumb idea, or a brilliant solution?
