I do have a couple of other questions though...
Around here we don't have to have holding tanks
at all (I'm putting one in because I want to, not because I'm obliged to), so as a result, pump-out facilities are few and far between. So, the question is; will it ever be necessary to be able to physically pump the contents of the holding tank out through the pump-out deck outlet, or will all
pump-put facilities have the pump capacity to suck iit all out without any assistance from on-board systems?
Also, would a 12v maverating pump be the way to go for pumping the tank to the through hull
outlet (when offshore), or would some other sort of 12v pump be better (assuming it has already been macerated by the toilet pump)? Or would a manual pump be better?
Next. If I understand the posts above, a vented loop on the inlet side of the toilet needs to be between the pump and the bowl, because if on the suction side fo the pump, it will not function properly becauseit will suck air through the vent in the vented loop. That being the case, one must either (a) put the vented loop between the pump and the bowl, or have a solenoid operated vented loop that closes when the pump operates (as per Jabsco
12v toilets). Does anyone have any opinions on such solenoid operated doo-dahs? (my prejudice is KISS, but I'm often wrong
Finally,is it worth having an extra inlet into the tank to for flushing
it out, or is it viable to just flush it by pumping water through via the toilet?
