Re: Holding Tank O'Day 30
To be functional, you need much more than 6 gallons. Remember, you have to empty the contents of the bowl, then pump enough clean water behind it to move all the waste up to the vented loop (which should be above the waterline at max heel) and then all the way to the tank, wherever it is. A gallon per flush is commonly necessary. If you don't evacuate the rise to the loop, that hose will stink over time. Failing to flush all the contents to the tank is a prime cause of clogging.
Good choice of hose.
Use only barbed fittings with dual hose clamps. Some insanely come with smooth hose fittings. No goop/glue/sealant should ever be necessary. Any pipe fittings on the seacock or diverter should not require any adds to be water tight, but I don't see the harm in teflon tape or pipe dope. Someone may know better here.
