Fwiw, USCG regs require that all waste tanks
have a means of determining when the tank is at least 3/4 full. The Sealand Tankwatch I which has only one short internal probe was designed specifically to meet this requirement. However, the proble is so short that in most tanks
it's definition of 3/4 full is actually only about 1 flush away from FULL. If the tank is readily accessible for visible inspection
, it's not necessary to install a gauge. However, if its not, you need one.
But whether you do or not, it's a wise investment that prevents overflows out the vent that inevitably result in a blocked vent.
